Abstract: Several factors lead to expectations that the scale of larval dispersal and population connectivity of marine animals differs with latitude. We examine this expectation for demersal shorefishes, including relevant mechanisms, assumptions and evidence. We explore latitudinal differences in (i) biological (e.g. species composition, spawning mode, pelagic larval duration, PLD), (ii) physical (e.g. water movement, habitat fragmentation), and (iii) biophysical factors (primarily temperature, which could strongly affect development, swimming ability or feeding). Latitudinal differences exist in taxonomic composition, habitat fragmentation, temperature and larval swimming, and each difference could influence larval dispersal. Nevertheless, clear evidence for latitudinal differences in larval dispersal at the level of broad faunas is lacking. For ex le, PLD is strongly influenced by taxon, habitat and geographical region, but no independent latitudinal trend is present in published PLD values. Any trends in larval dispersal may be obscured by a lack of appropriate information, or use of ‘off the shelf’ information that is biased with regard to the species assemblages in areas of concern. Biases may also be introduced from latitudinal differences in taxa or spawning modes as well as limited latitudinal s ling. We suggest research to make progress on the question of latitudinal trends in larval dispersal.

Abstract: In demersal marine fishes, the dispersal of larvae determines the geographical scale of population connectivity, and larval behaviour may influence dispersal. Yet, little is known of the ontogeny of behaviours that can influence dispersal. The present study examined the development of these behaviours in pelagic larvae of tropical marine fishes (4–21 mm) that occupy non-reef habitats as adults: Eleutheronema tetradactylum (Polynemidae) and Leiognathus equulus (Leiognathidae). In the laboratory, critical speed (Ucrit) increased from 3 to 34 cm s–1 at 1.3–1.7 cm s–1 per mm of size, with the fastest larvae up to 50% faster. In situ speed increased from 4 to 25 cm s–1 at 0.7–2.2 cm s–1 per mm, and was 10–14 body length s–1 (60–90% of Ucrit). Endurance increased from 0 to km at 2.4–4.7 km per mm. In the sea, orientation precision did not change ontogenetically, both species tended to swim in loops, and neither significant overall directionality nor ontogenetic change in orientation was present. Larval orientation of these non-reef species was less precise than that of reef fishes. The two species differed in depth distribution, and one ascended ontogenetically. These behaviours can potentially influence dispersal outcomes over the full size range of these larvae.

Abstract: Latitude and body size are generally considered key drivers of swimming performance for larval marine fishes, but evidence suggests that evolutionary relationships and habitat may also be important. We used a comparative phylogenetic framework, data synthesis and case study approach to investigate how swimming performance differs among larvae of fish species across latitude. First, we investigated how swimming performance changed with body length, and we found that temperate reef fishes have the greatest increases in swimming performance with length. Secondly, we compared differences in three swimming performance metrics (critical swimming speed, in situ swimming, and endurance) among post‐flexion larvae, whilst considering phylogenetic relationships and morphology, and we found that reef fishes have higher swimming capacity than non‐reef (pelagic and non‐reef demersal) fishes, which is likely due to larger, more robust body sizes. Thirdly, we compared swimming performance of late‐stage larvae of tropical fishes with oceanographic data to better understand the ecological relevance of their high‐capacity swimming. We found that reef fishes have high swimming performance and grow larger than non‐reef fish larvae, which we suggest is due to the pressures to find a specific, patchily distributed habitat upon which to settle. Given the current bias towards studies on percomorph fishes at low latitudes, we highlight that there is a need for more research on temperate reef fish larvae and other percomorph lineages from high latitudes. Overall, our findings provide valuable context to understand how swimming and morphological traits that are important for dispersal and recruitment processes are selected for among teleost fish larvae.

Abstract: Lobotes, Datnioides and Hapalogenys are assigned to a newly defined Acanthuriformes on the basis of their pattern of tooth replacement (termed posterolateral tooth replacement), where new teeth form at the posterolateral ends of series. Posterolateral tooth replacement is shown to be a synamorphy of the order. The order is expanded to include Chaetodontidae, Pomacanthidae, Drepaneidae, Ephippidae, Leiognathidae, Antigonia, Scatophagidae and Capros, along with the more traditional members, Siganidae, Luvaridae, Zanclidae and Acanthuridae. Three-item analysis of 63 adult and larval morphological characters yields two optimal trees that differ only in the relative positions of Capros and Siganidae. The intersection tree of the two optimal trees is: (((Hapalogenys (Datnioides, Lobotidae)) (Pomacanthidae (Drepaneidae (Chaetodontidae (Ephippidae (Leiognathidae (Scatophagidae (Antigonia (Siganidae, Capros (Luvaridae (Zanclidae, Acanthuridae)))))))))))). This cladogram is compared with recent phylogenies based on analyses of sequence data, and few differences are found once the weakly-supported interior nodes of the latter are collapsed. Aside from expansion of the Acanthuriformes, the following classification changes are proposed in order to reflect the phylogenetic relationships: redefinition of the Lobotidae to include Lobotes, Datnioides and Hapalogenys separate families for Antigonia and Capros (Antigoniidae and Caproidae, respectively) continued recognition of Drepaneidae (often considered a synonym of Ephippidae). The larvae of Capros aper are illustrated to show features overlooked in earlier descriptions.

Abstract: For much of their pelagic larval dispersal (PLD) stage, larval perciform fishes are able to directly influence their dispersal by horizontal swimming, but it is unclear which means of measuring swimming ability is most appropriate for modelling dispersal and studying demographic and genetic connectivity. Most studies use critical speed (Ucrit), a laboratory flume measure derived by increasing flow until larvae can no longer maintain their position. Most swimming ability data on fish larvae are Ucrit, usually for larvae nearing the end of PLD. Recognizing that a forced laboratory measure is inappropriate for dispersal, researchers have used decreased Ucrit values, usually by 50%, and have argued that Ucrit is strongly correlated with more relevant swimming measures. Here I examined the suitability of Ucrit versus in situ speed (ISS), wherein speed of larvae is measured by ers following them in the ocean with a flow meter. Considerations of dispersal require inclusion of swimming ontogeny. Swimming speed regressions of speed on size of 10 species in 8 families showed that Ucrit and ISS are not well correlated. The Ucrit:standard length (SL) slope was greater than the ISS:SL slope in 6 species, and did not differ in the other 4 species. No overall metric, e.g. X % of Ucrit = ISS, was appropriate for conversion of Ucrit to ISS. Conversion of Ucrit to ISS is not straightforward. Ucrit measures swimming potential, not what larvae do in the ocean, whereas ISS directly measures larvae swimming in the ocean. Ucrit ontogeny is less variable, but ISS ontogeny is more relevant to dispersal. Ucrit may be useful for other purposes.

Abstract: Dispersal emerges as a consequence of how an in idual's phenotype interacts with the environment. Not all dispersing in iduals have the same phenotype, and variation among in iduals can generate complex variation in the distribution of dispersal distances and directions. While active locomotion performance is an obvious candidate for a dispersal phenotype, its effects on dispersal are difficult to measure or predict, especially in small organisms dispersing in wind or currents. Therefore, we analyzed the effects of larval swimming on dispersal and settlement of coral‐reef fish larvae using a high‐resolution biophysical model. The model is, to date, the only biophysical model of marine larval dispersal that has been statistically validated against genetic parentage estimates of larval origin and destination, and incorporates empirically‐estimated larval behaviors and their ontogeny. Larval swimming, in combination with depth, orientation and navigation behaviors, actually reduced dispersal distances compared to those of passive larvae. Swimming had no consistent effects on long distance dispersal, but increased the spread of settlement locations. Swimming speed, in contrast, did not consistently affect median dispersal distances, but faster swimming larvae had greater mean and maximum dispersal distances than slower swimming larvae. Finally, faster larval swimming speeds consistently increased the probability of settlement. Our analysis shows how larval swimming differentially affects multiple properties of dispersal kernels. In doing so, it indicates how selection could favor faster larval swimming to increase settlement and local retention, which may actually result in longer dispersal distances as a by‐product of larvae trying to locate habitat rather than to disperse greater distances.

Abstract: Behavioural and ecological observations were made on young, reared Platax orbicularis in Opunohu Bay, Moorea, French Polynesia, during their transition from the pelagic, dispersive stage to the reef-orientated demersal stage. Seventy-two young P. orbicularis (17-75 mm standard length, LS ) were released in the pelagic zone and 20 (40-70 mm LS ) adjacent to the reefs. Swimming speed was slow (mean 5·2 cm s(-1) ) and independent of size. An ontogenetic descent was observed: the smallest P. orbicularis swam at the surface, medium-sized P. orbicularis swam in midwater (mean 5-13 m) and the largest P. orbicularis swam to the bottom, where many lay on their sides. Platax orbicularis swam southerly on average, away from the ocean and into the bay. Smaller P. orbicularis were more likely to swim directionally than larger in iduals. Young P. orbicularis released near reef edges swam at similar, but more variable speeds (mean 6·6 cm s(-1) ). About half of those released near reefs swam away, but fewer swam away from an inshore fringing reef than from a patch reef near the bay mouth. Many P. orbicularis swam up the slope onto the reef top, but the little settlement observed was near the reef base. Average, near-reef swimming direction was also southerly. Some reef residents, in particular the triggerfish Balistapus undulatus, harassed young P. orbicularis.

Abstract: Nearly all demersal teleost marine fishes have pelagic larval stages lasting from several days to several weeks, during which time they are subject to dispersal. Fish larvae have considerable swimming abilities, and swim in an oriented manner in the sea. Thus, they can influence their dispersal and thereby, the connectivity of their populations. However, the sensory cues marine fish larvae use for orientation in the pelagic environment remain unclear. We review current understanding of these cues and how sensory abilities of larvae develop and are used to achieve orientation with particular emphasis on coral-reef fishes. The use of sound is best understood it travels well underwater with little attenuation, and is current-independent but location-dependent, so species that primarily utilize sound for orientation will have location-dependent orientation. Larvae of many species and families can hear over a range of ~100-1000 Hz, and can distinguish among sounds. They can localize sources of sounds, but the means by which they do so is unclear. Larvae can hear during much of their pelagic larval phase, and ontogenetically, hearing sensitivity, and frequency range improve dramatically. Species differ in sensitivity to sound and in the rate of improvement in hearing during ontogeny. Due to large differences among-species within families, no significant differences in hearing sensitivity among families have been identified. Thus, distances over which larvae can detect a given sound vary among species and greatly increase ontogenetically. Olfactory cues are current-dependent and location-dependent, so species that primarily utilize olfactory cues will have location-dependent orientation, but must be able to swim upstream to locate sources of odor. Larvae can detect odors (e.g., predators, conspecifics), during most of their pelagic phase, and at least on small scales, can localize sources of odors in shallow water, although whether they can do this in pelagic environments is unknown. Little is known of the ontogeny of olfactory ability or the range over which larvae can localize sources of odors. Imprinting on an odor has been shown in one species of reef-fish. Celestial cues are current- and location-independent, so species that primarily utilize them will have location-independent orientation that can apply over broad scales. Use of sun compass or polarized light for orientation by fish larvae is implied by some behaviors, but has not been proven. Use of neither magnetic fields nor direction of waves for orientation has been shown in marine fish larvae. We highlight research priorities in this area.

Abstract: Fish swimming capacity is a key life history trait critical to many aspects of their ecology. U-crit (critical) swimming speeds provide a robust, repeatable relative measure of swimming speed that can serve as a useful surrogate for other measures of swimming performance. Here we collate and make available one the most comprehensive datasets on U-crit swimming abilities of tropical marine fish larvae and pelagic juveniles, most of which are reef associated as adults. The dataset includes U-crit speed measurements for settlement stage fishes across a large range of species and families obtained mostly from field specimens collected in light traps and crest nets and the development of swimming abilities throughout ontogeny for a range of species using reared larvae. In nearly all instances, the size of the in idual was available, and in many cases, data include other morphological measurements (e.g. “propulsive area”) useful for predicting swimming capacity. We hope these data prove useful for further studies of larval swimming performance and other broader syntheses.

Abstract: We describe the larval development of the sparid Pagellus natalensis based on 34 field specimens of 2–19 mm from the western Indian Ocean off South Africa. P. natalensis has unusual larval morphology for a sparid: in particular, extensive head spination including a serrate supraoccipital crest, serrate supraocular, pterotic, and supracleithral ridges, interopercular spines, strong preopercular spination, and pitted frontal bones. Development in the family Sparidae is briefly reviewed, and larval development of P. natalensis is central to this review. We suggest that larval morphology reveals much about sparid relationships, and pose several hypotheses for further testing. These include: Pagellus, Pagrus and Dentex as currently conceived are polyphyletic Pagellus affinis, bellottii and natalensis and Pagrus pagrus are closely related, as is an unidentified larval sparid from the eastern north Atlantic spiny larval morphology is derived within the Sparidae and indicates that the currently recognized subfamilies are polyphyletic Spondyliosoma is monophyletic Calamus and Spondyliosoma are sister taxa.

Abstract: Artificial-reef units (rolls of plastic garden mesh) attached to subsurface floats were used to study settlement behaviour of larval reef fishes. These units were located 3, 5, 7 and 9 m above the bottom in water 15–19 m deep in the Great Barrier Reef Lagoon, 1 km from natural reefs. Larvae of 50 species (15 families) settled on these units. The nine most abundant reef-fish taxa were in the families Apogonidae, Blenniidae, Gobiidae, Monacanthidae, Pomacentridae and Tetraodontidae. The less abundant of these taxa (n = 4) settled uniformly. The more abundant taxa (n = 5) had clumped settlement. Four taxa preferred structurally complex reef units, whereas five showed no preference. Apogonids, gobiids, tetraodontids and a pomacentrid preferred deep units, one pomacentrid had no depth preference, and a blenniid and a monacanthid preferred shallow units. Experiments evaluated visual, olfactory and auditory cues that reef-fish larvae may use to locate and settle onto reefs. Visual cues (large white panels) did not enhance settlement. Experiments on olfactory cues (corals in vented containers) and auditory cues (‘the nocturnal chorus’ of tropical reefs) were compromised by low and highly variable settlement, but show the potential of the method. The advantages of subsurface moorings for study of settlement behaviour are discussed.

Abstract: Nearly all teleost reef fishes are pelagic during the larval stage, returning at the end of this stage to settle in a reefal habitat. Little is known about their sensory capabilities or how larvae detect and locate a reef. Sound is the most likely cue, particularly since reef shrimp and fish choruses are audible at considerable distances. Playback experiments off Lizard Island, Great Barrier Reef, broadcast nocturnal reef sounds and artificial sounds (pure tones) in the presence of settlement stage larvae of the coral-reef damselfish Chromis atripectoralis, released during the day within 100 m of the underwater speaker 500–1000 m from the nearest reef. Larvae consistently swam to the south in the absence of playback and during playback of artificial sounds. During playback of reef sounds, they showed no overall swimming direction, indicating that they can hear and can distinguish between a sound with potential biological significance and one without. Light traps with and without playback of reef sounds on 33 paired (playback: nonplayback) trap nights resulted in higher catches for 14 of 17 families for which & in iduals were trapped. This suggests that not only can larvae hear, but they also have some aural localization capability.

Abstract: The larval stage is the main dispersive process of most marine teleost species. The degree to which larval behavior controls dispersal has been a subject of debate. Here, we apply a cross-species meta-analysis, focusing on the fundamental question of whether larval fish use external cues for directional movement (i.e., directed movement). Under the assumption that directed movement results in straighter paths (i.e., higher mean vector lengths) compared to undirected, we compare observed patterns to those expected under undirected pattern of Correlated Random Walk (CRW). We find that the bulk of larvae exhibit higher mean vector lengths than those expected under CRW, suggesting the use of external cues for directional movement. We discuss special cases which erge from our assumptions. Our results highlight the potential contribution of orientation to larval dispersal outcomes. This finding can improve the accuracy of larval dispersal models, and promote a sustainable management of marine resources.

Abstract: Biophysical dispersal models for marine fish larvae are widely used by marine ecologists and managers of fisheries and marine protected areas to predict movement of larval fishes during their pelagic larval duration (PLD). Over the past 25 years, it has become obvious that behaviour—primarily vertical positioning, horizontal swimming and orientation—of larvae during their PLD can strongly influence dispersal outcomes. Yet, most published models do not include even one of these behaviours, and only a tiny fraction include all three. Furthermore, there is no clarity on how behaviours should be incorporated into models, nor on how to obtain the quantitative, empirical data needed to parameterize models. The PLD is a period of morphological, physiological and behavioural change, which presents challenges for modelling. The present paper aims to encourage the inclusion of larval behaviour in biophysical dispersal models for larvae of marine demersal fishes by providing practical suggestions, advice and insights about obtaining and incorporating behaviour of larval fishes into such models based on experience. Key issues are features of different behavioural metrics, incorporation of ontogenetic, temporal, spatial and among-in idual variation, and model validation. Research on behaviour of larvae of study species should be part of any modelling effort.

Abstract: Late pelagic stages of coral reef fishes captured with light-traps were in idually released during daylight by SCUBA ers in open water, 20-35 m deep, in the Great Barrier Reef Lagoon at three sites 1 km from the reefs of Lizard Island. Observations in situ on 111 in iduals of 11 families, but primarily Apogonidae, Chaetodontidae and Pomacentridae, constitute the first data of their kind. Most fish showed no overt reaction to the ers. Some in iduals of some taxa of three families settled quickly to the bottom. Acceptable observations on swimming were made on 66 larvae. In iduals selected a wide range of depths, but when grouped by family, mean depths chosen by in iduals were: apogonids, 6.5 (� 1.5, 95% CI) m pomacentrids, 7.7 (� 1.5) m and chaetodontids, 9.3 (� 1.3) m. Rough estimates of speed of up to 30 cm s-1 varied among taxa. Swimming directions of 59 of the 66 larvae were non-random. Mean directions differed among sites and were offshore at all of them. Most larvae swam offshore regardless of the side of the island where they were released. The late pelagic stages of coral reef fishes are strong swimmers capable of active horizontal and vertical movement. They swim directionally, can apparently detect reefs km away, and orientate relative to those reefs. A taxonomic component is evident in many of these behaviours.

Abstract: The larvae of the two species of Pinjalo are described for the first time based on seven specimens of P. pinjalo (4.3–7.5 mm) and 23 specimens of P. lewisi (5.6–15.0 mm) captured in plankton tows and midwater trawls in the eastern Indian and western Pacific Oceans. Identification was confirmed by fin meristics. These deep-bodied, compressed larvae share all the characteristics of lutjanid larvae, and have some of the most well-developed head spination and fin spines of any lutjanids. The robust spines of the dorsal, anal and pelvic fins bear strong serrations. The preopercular spines are particularly enlarged, some bear fine serrations, and the anterior end of the maxilla also has fine serrations: these fine serrations are rare in lutjanine lutjanids. The two species of Pinjalo can be distinguished by the meristics of dorsal and anal fins, the relative lengths of the first spine of the dorsal fin and the spine of the pelvic fin. The larvae have distinctive pigment on the dorsal fin, head and caudal peduncle. The body shape, pigment pattern, fin-spine morphology, and the fine serrations on the head spines of the two Pinjalo species are very similar to the larvae of Lutjanus erythropterus and L. malabaricus, and may indicate a close relationship among these four species.

Abstract: Larval fishes are a useful metric of marine ecosystem state and change, as well as species-specific patterns in phenology. The high level of taxonomic expertise required to identify larval fishes to species level, and the considerable effort required to collect s les, make these data very valuable. Here we collate 3178 s les of larval fish assemblages, from 12 research projects from 1983-present, from temperate and subtropical Australian pelagic waters. This forms a benchmark for the larval fish assemblage for the region, and includes recent monitoring of larval fishes at coastal oceanographic reference stations. Comparing larval fishes among projects can be problematic due to differences in taxonomic resolution, and identifying all taxa to species is challenging, so this study reports a standard taxonomic resolution (of 218 taxa) for this region to help guide future research. This larval fish database serves as a data repository for surveys of larval fish assemblages in the region, and can contribute to analysis of climate-driven changes in the location and timing of the spawning of marine fishes.

Abstract: The larval stages of most marine fishes spend days to weeks in the pelagic environment, where they must find food and avoid predators in order to survive. Some fish only spend part of their life history in the pelagic environment before returning to their adult habitat, for ex le, a coral reef. The sensory systems of larval fish develop rapidly during the first few days of their lives, and here we concentrate on the various sensory cues the fish have available to them for survival in the pelagic environment. We focus on the larvae of reef fishes because most is known about them. We also review the major threats caused by human activities that have been identified to have worldwide impact and evaluate how these threats may impact larval-fish survival and orientation abilities. Many human activities negatively affect larval-fish sensory systems or the cues the fish need to detect. Ultimately, this could lead to decreased numbers of larvae surviving to settlement, and, therefore, to decreased abundance of adult fishes. Although we focus on species wherein the larvae and adults occupy different habitats (pelagic and demersal, respectively), it is important to acknowledge that the potential anthropogenic effects we identify may also apply to larvae of species like tuna and herring, where both larvae and adults are pelagic.

Abstract: Climate change is leading to shifts in species geographical distributions, but populations are also probably adapting to environmental change at different rates across their range. Owing to a lack of natural and empirical data on the influence of phenotypic adaptation on range shifts of marine species, we provide a general conceptual model for understanding population responses to climate change that incorporates plasticity and adaptation to environmental change in marine ecosystems. We use this conceptual model to help inform where within the geographical range each mechanism will probably operate most strongly and explore the supporting evidence in species. We then expand the discussion from a single-species perspective to community-level responses and use the conceptual model to visualize and guide research into the important yet poorly understood processes of plasticity and adaptation. This article is part of the theme issue ‘The role of plasticity in phenotypic adaptation to rapid environmental change’.

Abstract: Spatial and temporal distribution patterns of scombrid larvae along the east coast of South Africa were investigated from ichthyoplankton collections made during May–June 1990 (winter), October 1990 (spring) and February 1991 (summer). Results were analysed in relation to oceanographic conditions and known spawning localities of tuna and mackerels in the western Indian Ocean. In total, eight species were represented in the s les, with highest ersity in February and lowest numbers in May–June. Larvae of the temperate chub mackerel Scomber japonicus were most abundant at shelf stations during October. Larvae of neritic tunas Auxis sp. and Euthynnus affinis occurred in shelf stations off KwaZulu–Natal in February and extended southward in a plume along the shelf edge. Larvae of skipjack tunaKatsuwonus pelamis were most abundant in the Agulhas Current during February. Only a few larvae of oceanic tunas Thunnus spp., wahoo Acanthocybium solandri and king mackerel Scomberomorus commerson were collected in the Agulhas Current in the north of the study area during February when there was an intrusion of warm Tropical Surface Water. This indicates that spawning of these species probably does not occur off the east coast of South Africa.
