Abstract: The use of biotelemetry in hibian behaviour, migration, dispersal and homing research has increased with the miniaturisation and improved reliability of telemetry equipment. Here we synthesise biotelemetry methods and outcomes from the past two decades of published studies ( n = 128 1 January 2000–31 December 2020). We discuss trends in hibian study duration, transmitter weight and transmitter attachment methods. The most commonly used harness designs for external transmitter attachment and surgical methods for internal implantation are described, and the benefits and potential problems of these methods are discussed. We recommend improved practices for future studies and address gaps within the current hibian telemetry literature in regard to accurately reporting study endpoints and study subject survival. Finally, we highlight emerging technologies that could influence the next 20 years of telemetry research on hibians.

Abstract: Biotic interactions can shape phylogenetic community structure (PCS). However, we do not know how the asymmetric effects of foundation species on communities extend to effects on PCS. We assessed PCS of alpine plant communities around the world, both within cushion plant foundation species and adjacent open ground, and compared the effects of foundation species and climate on alpha (within-microsite), beta (between open and cushion) and gamma (open and cushion combined) PCS. In the open, alpha PCS shifted from highly related to distantly related with increasing potential productivity. However, we found no relationship between gamma PCS and climate, due to ergence in phylogenetic composition between cushion and open sub-communities in severe environments, as demonstrated by increasing phylo-beta ersity. Thus, foundation species functioned as micro-refugia by facilitating less stress-tolerant lineages in severe environments, erasing a global productivity - phylogenetic ersity relationship that would go undetected without accounting for this important biotic interaction.

Abstract: Fire appears to be a rare event in alpine vegetation, suggesting that its effects might be more persistent than in most lowland vegetation types. However, it has been suggested that the Australian alpine biota is resilient to infrequent large fires. This paper describes decades-scale vegetation and soil change after fire in paired plots over fire boundaries in Tasmanian alpine coniferous heath. The effect of fire on soils persisted for decades. Recovery of vegetation was extremely slow by global standards, with delayed reinvasion of previously dominant species. There was low cover of the most fire-sensitive species 43–69 years after fire and much bare ground still evident, with the rate of revegetation declining through time. Gymnosperm shrubs increased at the expense of angiosperms in the unburned plots in the same period and cryptogams declined in both burned and unburned plots. These results suggest that the Tasmanian alpine flora cannot be characterised as resilient to infrequent large fire, although most species survive its incidence. The many centuries that it appears are necessary for coniferous heath to recover to its pre-burn state suggest that fires caused by increased ignitions from lightning and arsonists are the major issue for conservation of the vegetation type.

Abstract: Observations were made across 11-40-year-old fire boundaries in Tasmanian alpine areas of varying macroenvironment and flora. Organic matter and total nitrogen in the surface soil were significantly less where the vegetation had been recently burned. There were no significant differences between recently burned and recently unburned plots in contents of phosphorus, potassium, calcium or sodium or in pH. The burned plots contained few or no gymnosperms or deciduous shrubs, the most frequent dominants of the unburned vegetation. Most other shrubs were markedly less important in the burned than in the unburned plots, although most species of bolster form were little affected by fire, and some composite shrubs were most abundant on the burned plots. Most herbaceous species had equal or greater cover on the burned plots than on the unburned plots. The burned vegetation of the eastern mountains appeared to regenerate more quickly than that of the more oligotrophic western mountains.

Abstract: Interactions among species determine local-scale ersity, but local interactions are thought to have minor effects at larger scales. However, quantitative comparisons of the importance of biotic interactions relative to other drivers are rarely made at larger scales. Using a data set spanning 78 sites and five continents, we assessed the relative importance of biotic interactions and climate in determining plant ersity in alpine ecosystems dominated by nurse-plant cushion species. Climate variables related with water balance showed the highest correlation with richness at the global scale. Strikingly, although the effect of cushion species on ersity was lower than that of climate, its contribution was still substantial. In particular, cushion species enhanced species richness more in systems with inherently impoverished local ersity. Nurse species appear to act as a 'safety net' sustaining ersity under harsh conditions, demonstrating that climate and species interactions should be integrated when predicting future bio ersity effects of climate change.

Abstract: The relative impacts of clearfelling followed by slash-burning, clearfelling, and no treatment were monitored for 2 years in two major types of eucalypt forest in south-eastern Tasmania. Rates of change in species cover were significantly greater in the burned area than in both the clearfell and control areas. More than half the species for which suitable data were available increased most in the burned area and least in the control. More higher plant taxa were present in the permanent burned plots 4 months after the burn than before the burn. By the last 8 months of recording, new taxa were invading at a rate of only 0.1 per month. Composites and shrubs constituted most of the late invaders. The behaviour of ersity measures was largely a function of the behaviour of a few of the taxa. Fire intensity, as measured by degree of soil baking, had a pronounced influence on species composition and cover. The species composition of aerially sown seed had little influence on the species composition of the eucalypt regeneration, with species not sown by the Forestry Commission recovering vegetatively, and much of the sown seed not resulting in seedling establishment. The clearfelling and burning, and clearfelling treatments did not result in the loss of any native species but there was substantial invasion by introduced herbs. However, lack of substantial impact in the short term does not guarantee the same in the long term.

Abstract: If snow cover in alpine environments were reduced through climatic warming, plants that are normally protected by snow-lie in winter would become exposed to greater extremes of temperature and solar radiation. We examined the annual course of frost resistance of species of native alpine plants from southern New Zealand that are normally buried in snowbanks over winter (Celmisia haastii and Celmisia prorepens) or in sheltered areas that may accumulate snow (Hebe odora) and other species, typical of more exposed areas, that are relatively snow-free (Celmisia viscosa, Poa colensoi, Dracophyllum muscoides). The frost resistance of these principal species was in accord with habitat: those from snowbanks or sheltered areas showed the least frost resistance, whereas species from exposed areas had greater frost resistance throughout the year. P. colensoi had the greatest frost resistance (-32.5 degrees C). All the principal species showed a rapid increase in frost resistance from summer to early winter (February-June) and maximum frost resistance in winter (July-August). The loss of resistance in late winter to early summer (August-December) was most rapid in P. colensoi and D. muscoides. Seasonal frost resistance of the principal species was more strongly related to daylength than to temperature, although all species except C. viscosa were significantly related to temperature when the influence of daylength was accounted for. Measurements of chlorophyll fluorescence indicated that photosynthetic efficiency of the principal species declined with increasing daylength. Levels of frost resistance of the six principal alpine plant species, and others measured during the growing season, were similar to those measured in tropical alpine areas and somewhat more resistant than those recorded in alpine areas of Europe. The potential for frost damage was greatest in spring. The current relationship of frost resistance with daylength is sufficient to prevent damage at any time of year. While warmer temperatures might lower frost resistance, they would also reduce the incidence of frosts, and the incidence of frost damage is unlikely to be altered. The relationship of frost resistance with daylength and temperature potentially provides a means of predicting the responses of alpine plants in response to global warming.
