Interactions between the introduced European honey bee and native bees in urban areas varies by year, habitat type and native bee guild
Publisher: Oxford University Press (OUP)
Date: 05-04-2021
DOI: 10.1093/BIOLINNEAN/BLAB024
Abstract: European honey bees have been introduced across the globe and may compete with native bees for floral resources. Compounding effects of urbanization and introduced species on native bees are, however, unclear. Here, we investigated how honey bee abundance and foraging patterns related to those of native bee abundance and ersity in residential gardens and native vegetation remnants for 2 years in urbanized areas of the Southwest Australian bio ersity hotspot and assessed how niche overlap influenced these relationships. Honey bees did not overtly suppress native bee abundance however, complex relationships emerged when analysing these relationships according to body size, time of day and floral resource levels. Native bee richness was positively correlated with overall honeybee abundance in the first year, but negatively correlated in the second year, and varied with body size. Native bees that had higher resource overlap with honey bees were negatively associated with honey bee abundance, and resource overlap between honey bees and native bees was higher in residential gardens. Relationships with honey bees varied between native bee taxa, reflecting adaptations to different flora, plus specialization. Thus, competition with introduced bees varies by species and location, mediated by dietary breadth and overlap and by other life-history traits of in idual bee species.

Leioproctus zephyr Prendergast (Hymenoptera, Colletidae, Leioproctus), an oligoletic new bee species with a distinctive clypeus
Publisher: Pensoft Publishers
Date: 31-10-2022
DOI: 10.3897/JHR.93.85685
Abstract: A new species Leioproctus zephyr (Hymenoptera: Colletidae) is described from both sexes. Leioproctus zephyr sp. nov. is remarkable in featuring a large longitudinal ridge on the clypeus. This diagnostic morphological feature present in both sexes, along with various other distinctive characters including the male genitalia, female hind-tibial spur, and glossa morphology, clearly distinguish this species from all other Leioproctus . Along with these unique traits, L. zephyr cannot be classified into any of the existing subgenera of Leioproctus , sharing some, but not all, of the characters of the subgenera Ceratocolletes , Charicolletes , Protomorpha and Odontocolletes . DNA barcoding with the CO1 gene confirmed the sexes belonged to the same species and it did not match any previously barcoded species. This species is restricted to native vegetation remnants in the southwest Western Australian bio ersity hotspot, and is highly specialised, foraging only on a few species in the genus Jacksonia (Fabaceae). The unusual clypeus may be an adaptation for foraging on the keeled papilionaceous flowers. The limited number of sites this species has been collected from and its oligolectic diet suggest L. zephyr should be considered to be a species of conservation concern. Further taxonomic research is required to determine the phylogenetic position of this unusual Leioproctus .

The evidence for and against competition between the European honeybee and Australian native bees
Publisher: CSIRO Publishing
Date: 03-03-2022
DOI: 10.1071/PC21064
Abstract: In Australia, the European honeybee (Apis mellifera) is an exotic, abundant, super-generalist species. Introduced two centuries ago, it thrives in the absence of many diseases adversely impacting honeybees elsewhere. Australia’s native bees may be vulnerable to competition with honeybees, leading to reduced abundances, reproductive output or even loss of bee species. We review the literature concerning competition between honeybees and Australian native bees in order to: (1) identify the valuence and strength of honeybee associations with native bees, and how this varies according to the response variable measured (2) assess potential research biases (3) use ecological theory to explain variation in results and (4) identify key knowledge gaps. We found honeybees typically comprised the majority of in iduals in surveys of Australian bee communities. Data on whether honeybees outcompete native bees is equivocal: there were no associations with native bee abundance, species richness, or reproductive output in most cases. However, there were more negative than positive associations. Data indicate effects of honeybees are species-specific, and more detailed investigations regarding how different species and life-history traits affect interactions with honeybees is needed. We propose the following investigations to address deficiencies in the current literature: greater geographic and landscape representation trait-based investigations quantifying resource availability and overlap disease and predator interactions experimental feral colony removals and studies spanning multiple seasons and years. Identifying conditions under which honeybees have negative, neutral or positive effects on native bees, and how the ecological traits of native bees are affected by honeybee competition can guide conservation and management.

Potential and pitfalls of citizen science with children: Reflections on Pollinators in the Playground project
Publisher: Wiley
Date: 11-03-2021
DOI: 10.1111/AEC.13031
Abstract: Engaging school‐age children in activities involving ‘real‐world’ science and interacting with scientific researchers can promote an interest in appreciating and understanding the natural world and the scientific method. Here, we describe a project involving five female early‐career and PhD researchers who facilitated a citizen science project with school‐age children. Under the guidance of the researchers, across five schools, children created artificial flowers and installed them on school ovals. Over repeated 10‐min observations, students recorded how colour (yellow vs. blue) and configuration (isolated, clumped adjacent, clumped mixed colour and clumped single colour) influenced how many and what taxa of insects visited. Here, we reflect on what we were able to achieve including creating a simple, fun, cost‐effective project anecdotal student interest in insects, and positive female STEM role models. We also acknowledge constraints and shortcomings, including set curricula resulting in suboptimal season for pollinator studies confounding of results due to children’s observations and being unable to verify the data. We offer recommendations for more robust projects in future, which include collecting specimens to verify results, and measuring learning outcomes. If these recommendations are met, researcher–student projects can engage children in conducting scientific experiments with applications for home and school garden management.

A global review of determinants of native bee assemblages in urbanised landscapes
Publisher: Wiley
Date: 10-02-2022
DOI: 10.1111/ICAD.12569
Abstract: Loss of natural habitat through land‐use change threatens bees. Urbanisation is a major, increasing form, of habitat loss, and a novel, pervasive form of disturbance known to impact bee ersity and abundance in a variety of often inconsistent ways. We conducted a comprehensive, semi‐quantitative review, involving 215 studies, on responses of bees to urban landscapes, and local and landscape variables proposed to influence bee abundance and ersity. Urban areas tend to be favourable habitat for bees compared with agricultural ones, but compared with natural areas, urban areas often host more abundant populations yet fewer species. Factors associated with urban landscapes, including changes in foraging resources and nesting substrate types and availability, contribute to changes in abundance, species richness, and composition of native bee assemblages. However, the conclusions of studies vary greatly because of the difference in the ecological traits of bees, habitats surveyed, and geographic region, as well as noise in the data resulting from inconsistencies in s ling methodology, and definitions of ‘urban’ and ‘natural’. Identifying what biotic and abiotic features of cityscapes promote or threaten the persistence of urban bee ersity is critical. We provide a comprehensive evaluation of how bees (both in aggregate and according to their ecological guild) have responded to the urban environment, identify gaps in knowledge in urban bee ecology, and make recommendations to advance our understanding of bees in urban environments to promote conservation of erse bee communities.

Honey bees (Hymenoptera: Apidae) outnumber native bees in Tasmanian apple orchards: Perspectives for balancing crop production and native bee conservation
Publisher: Wiley
Date: 03-02-2021
DOI: 10.1111/AEN.12521
Abstract: Apples are a major crop globally, including in Tasmania (Australia) – known as ‘the Apple Isle’ owing to the key role of apples in Tasmania's history and economy. Most apple cultivars are obligate entomophilous species, and fruit quantity, quality and economic value are enhanced under insect pollination. Whilst the introduced European honey bee ( Apis mellifera ) is often assumed to be the main pollinator of apple in most regions of the world, including Australia, there is an increasing interest in alternative pollinators. The pollinator community of Tasmanian apple crops, however, has never been assessed. In this study, we surveyed four apple orchards for 3 days each during peak bloom in the Huon Valley region to characterise bee assemblages visiting blooming apple trees and the native bee fauna associated with surrounding flowering vegetation. Our results show that honey bees were the predominant visitors to apple blossoms (90.7% of visits), followed by the introduced bumble bee Bombus terrestris (5.9% of visits), with only a minor contribution by native bees (3.3% of visits). Twenty‐six species of native bees were collected in total, of which only 10 species (five Exoneura (Apidae), four Lasioglossum (Halictidae) and one Euryglossa (Colletidae) species) were collected from apple blossoms, with Exoneura being the most abundant visitors. Few native bees were captured on apple blossoms, however co‐blooming surrounding native vegetation, as well exotic flowers, hosted a high ersity and abundance of native bees. Site conditions influenced community composition, including abundance and representation of introduced bees compared to native bees visiting apples. Additionally, warmer temperatures favoured native bees. Collectively, our results suggest that Tasmania's apple production in its current state is unlikely to rely exclusively on native pollinators. Native bees nevertheless warrant conservation in such an insular crop production system. This can be achievable through retaining native flowering plants and even exotic non‐crop flowers in and around orchards. Promoting the ersity and abundance of native bees through habitat enhancement may have additional benefits, such as filling current and future pollination demands and gaps, a key strategy under scenarios of climate change.

Spatial and temporal scale of analysis alter conclusions about the effects of urbanisation on plant–pollinator networks

DOI: 10.1007/S11829-022-09925-W
Abstract: Bipartite networks of flowering plants and their visitors (potential pollinators) are increasingly being used in studies of the structure and function of these ecological interactions. Whilst they hold much promise in understanding the ecology of plant–pollinator networks and how this may be altered by environmental perturbations, like land-use change and invasive species, there is no consensus about the scale at which such networks should be constructed and analysed. Ecologists, however, have emphasised that many processes are scale dependent. Here, we compare network- and species-level properties of ecological networks analysed at the level of a site, pooling across sites within a given habitat for each month of surveys, and pooling across all sites and months to create a single network per habitat type. We additionally considered how these three scales of resolution influenced conclusions regarding differences between networks according to two contrasting habitat types (urban bushland remnants and residential gardens) and the influence of honey bee abundance on network properties. We found that most network properties varied markedly depending on the scale of analysis, as did the significance, or lack thereof, of habitat type and honey bee abundance on network properties. We caution against pooling across sites and months as this can create unrealistic links, invalidating conclusions on network structure. In conclusion, consideration of scale of analysis is also important when conducting and interpreting plant–pollinator networks.

Monitoring the birds and the bees: Environmental DNA metabarcoding of flowers detects plant–animal interactions
Publisher: Wiley
Date: 08-03-2023
DOI: 10.1002/EDN3.399
Abstract: Animal pollinators are vital for the reproduction of ~90% of flowering plants. However, many of these pollinating species are experiencing declines globally, making effective pollinator monitoring methods more important than ever before. Pollinators can leave DNA on the flowers they visit, and metabarcoding of these environmental DNA (eDNA) traces provides an opportunity to detect the presence of flower visitors. Our study, collecting flowers from seven plant species with erse floral morphologies, for eDNA metabarcoding analysis, illustrated the value of this novel survey tool. eDNA metabarcoding using three assays, including one developed in this study to target common bush birds, recorded more animal species visiting flowers than visual surveys conducted concurrently, including birds, bees, and other species. We also recorded the presence of a flower visit from a western pygmy possum to our knowledge this is the first eDNA metabarcoding study to simultaneously identify the interaction of insect, mammal, and bird species with flowers. The highest ersity of taxa was detected on large inflorescence flower types found on Banksia arborea and Grevillea georgeana. The study demonstrates that the ease of s le collection and the robustness of the metabarcoding methodology has profound implications for future management of bio ersity, allowing us to monitor both plants and their attendant cohort of potential pollinators. This opens avenues for rapid and efficient comparison of bio ersity and ecosystem health between different sites and may provide insights into surrogate pollinators in the event of pollinator declines.

Impacts of the introduced European honeybee on Australian bee‐flower network properties in urban bushland remnants and residential gardens
Publisher: Wiley
Date: 19-05-2022
DOI: 10.1111/AEC.13040
Abstract: The European honeybee Apis mellifera is a highly successful, abundant species and has been introduced into habitats across the globe. As a supergeneralist species, the European honeybee has the potential to disrupt pollination networks, especially in Australia, whose flora and fauna have co‐evolved for millions of years. The role of honeybees in pollination networks in Australia has been little explored and has never been characterised in urban areas, which may favour this exotic species due to the proliferation of similarly exotic plant species which this hyper‐generalist can utilise, unlike many native bee taxa. Here, we use a bipartite network approach to compare the roles, in terms of species‐level properties, of honeybees with native bee taxa in bee‐flower (‘pollination’) networks in an urbanised bio ersity hotspot. We also assessed whether the abundance of honeybees influences overall network structure. Pollination networks were created from surveys across seven residential gardens and seven urban native vegetation remnants conducted monthly during the spring‐summer period over two years. There were consistent differences in species‐level properties between bee taxa, with honeybees often differing from all other native bees. Honeybees had significant impacts on network properties, being associated with higher nestedness, extinction slopes of plants, functional complementarity and niche overlap (year two), as well as lower weighted connectance and generalisation. These associations all are indicative that competition is occurring between the introduced honeybee and the native bee taxa in bee‐flower networks. In conclusion, the introduced honeybee occupies a dominant, distinct position in bee‐flower networks in urban habitats in the southwest Western Australian bio ersity hotspot and has a major, potentially disruptive, influence on plant‐pollinator network properties in these areas.

Screening Canola Genotypes for Resistance to Ammonium Toxicity
Publisher: MDPI AG
Date: 18-04-2023
Abstract: Soil ammonium toxicity can decrease plant growth, and many crop species have low resistance to ammonium, including canola, an economically important crop. Different genotypes may differ in their resistance to ammonium toxicity, and therefore determining if there are genotypes that exhibit variation in their ability to tolerate soil ammonium is a research priority. Here, we evaluate how soil ammonium impacts canola root and shoot growth and characterise differences among canola genotypes in regard to resistance to ammonium toxicity. In the first experiment, eight ammonium chloride treatments and five calcium nitrate treatments were tested for their impact on the canola genotype Crusher TT, where high application (60 mg N/kg soil) significantly decreased the dry weight of canola shoots and roots and acidified the soil from pHCaCl2 5.9 to 5.6. In the second experiment, 30 canola genotypes were screened at selected concentrations of NH4+-N, using nitrate as the control. There was wide variation among genotypes in sensitivity to high NH4+-N application. Genotypes G16, G26, and G29 had greater shoot dry weights and the highest shoot N concentration of all genotypes, and G16, G26, and G28 had root dry weight up to 35% higher at high soil NH4+-N compared with other genotypes. In contrast, genotypes G3, G13, and G30 showed the largest reduction in shoot weight, and genotypes G13, G23, and G30 showed the largest reduction in root weight at high NH4+-N application. Residual NH4+-N/kg soil in soil was higher for sensitive than resistant genotypes, suggesting lower NH4+-N use in the former. These results reveal the potential for selecting canola genotypes that are resistant to high NH4+-N concentrations in soil.
Continental risk assessment for understudied taxa post‐catastrophic wildfire indicates severe impacts on the Australian bee fauna
Publisher: Wiley
Date: 30-09-2021
DOI: 10.1111/GCB.15879
Abstract: The 2019–2020 Australian Black Summer wildfires demonstrated that single events can have widespread and catastrophic impacts on bio ersity, causing a sudden and marked reduction in population size for many species. In such circumstances, there is a need for conservation managers to respond rapidly to implement priority remedial management actions for the most‐affected species to help prevent extinctions. To date, priority responses have been biased towards high‐profile taxa with substantial information bases. Here, we demonstrate that sufficient data are available to model the extinction risk for many less well‐known species, which could inform much broader and more effective ecological disaster responses. Using publicly available collection and GIS datasets, combined with life‐history data, we modelled the extinction risk from the 2019–2020 catastrophic Australian wildfires for 553 Australian native bee species (33% of all described Australian bee taxa). We suggest that two species are now eligible for listing as Endangered and nine are eligible for listing as Vulnerable under IUCN criteria, on the basis of fire overlap, intensity, frequency, and life‐history traits: this tally far exceeds the three Australian bee species listed as threatened prior to the wildfire. We demonstrate how to undertake a wide‐scale assessment of wildfire impact on a poorly understood group to help to focus surveys and recovery efforts. We also provide the methods and the script required to make similar assessments for other taxa or in other regions.
First records of the introduced African carder bee, Pseudoanthidium (Immanthidium) repetitum (Hymenoptera:Megachilidae), in Western Australia
Publisher: CSIRO Publishing
Date: 2020
DOI: 10.1071/PC20041
Abstract: Globalisation has increased the occurrence of species being introduced outside of their natural range. The African carder bee, Pseudoanthidium (Immanthidium) repetitum (Hymenoptera: Megachilidae), is one such species. P. repetititum was first recorded in Australia in 2000 in Queensland (north-east Australia), and rapidly spread down the east coast of Australia, and by 2015 was reported to be a common component of bee assemblages in urban community gardens in Victoria (southern Australia). Here, I report the first occurrences of this species in Western Australia, on the other side of the continent, representing a major expansion of the distribution of the species. Thus far there are three confirmed and one unconfirmed localities where this species has been seen, all localised to the Mandurah region in residential areas of Western Australia. Female specimens were collected from a garden in Halls Head, where it was observed to be abundant. Other bees, both native and the introduced European honeybee, were foraging alongside it. The occurrence of P. repetitum represents a major expansion in its distribution. It remains rare and localised however, given known negative impacts of introduced species on native fauna and flora, especially in Australia, vigilance is required to monitor this species.
Checking in at bee hotels: trap-nesting occupancy and fitness of cavity-nesting bees in an urbanised biodiversity hotspot
Publisher: Springer Science and Business Media LLC

DOI: 10.1007/S11252-023-01381-5
Abstract: With urbanisation leading to loss of nesting resources, and increasing public interest in helping bees, bee hotels (trap-nests) are becoming popularised. However, their success is relatively understudied. The influence of habitat type in determining occupancy and emergence is also poorly known. Over two years across 7 bushland remnant and 7 residential garden sites, trap-nests were installed and completed nests collected monthly over spring-summer. Bees appeared to take a month to find the trap-nests, irrespective of month they were installed. A small percentage (13% and 6% in the two years) of tubes were occupied, but this was within the range of other trap-nesting studies. Smaller 4 and 7 mm diameter nests had a higher occupancy rate than 10 mm diameter tubes. An impressive number − 24 bee species – occupied the trap-nests. Representation however was dominated by five species. The species composition (species and their relative abundances) of cavity-nesting bees differed greatly between those using the trap-nests compared with those observed in the field. Bushland remnants tended to have more bee hotels occupied, and male body size of emerged bees was larger in this habitat. Unexpectedly native and total flower ersity reduced bee hotel occupancy, whereas native flower parameters tended to positively influence bee fitness. Overall installing bee hotels can provide additional nesting resources for native bees in urbanised areas, and providing high proportions of native flora in the vicinity should enhance fitness of the bees using them.

Natural history note: Urban domestic gardens support nesting populations of the native bee Leioproctus (Leioproctus) plumosus
Publisher: Wiley
Date: 17-02-2022
DOI: 10.1111/AEC.13016
Abstract: The nesting habits of many Australian native bees are poorly known, with observations of nests being few and far in between. Here, I report three independent nesting aggregations of a native colletid bee Leioproctus (Leioproctus) plumosus , accompanied by videos of its nesting behaviour and photographs of its nesting substrate. These discoveries were made possible through the citizen science group ‘Bees in the burbs’. Despite extensive surveys in the region, the only nesting occurrences of L. plumosus have been found in domestic gardens, all in highly urbanised areas. With this species more frequently encountered in residential gardens, this suggests that despite evidence of ground‐nesting bees being relatively disadvantaged by urban development due to replacement of bare ground with impervious surfaces, this species is able to still use residential areas for nesting. I propose potential explanations for this phenomenon, which includes new observations of commonly foraging on Callistemon – a popular tree in gardens and on nature strips. That this native bee’s nests appear to be associated with residential gardens provides both opportunities to engage citizen scientists in documenting and preserving native bee populations, but also indicates the threat ongoing urban development may pose.

DOI: 10.26786/1920-7603(2022)695
Abstract: During the main COVID-19 global pandemic lockdown period of 2020 an impromptu set of pollination ecologists came together via social media and personal contacts to carry out standardised surveys of the flower visits and plants in gardens. The surveys involved 67 rural, suburban and urban gardens, of various sizes, ranging from 61.18° North in Norway to 37.96° South in Australia, resulting in a data set of 25,174 rows, with each row being a unique interaction record for that date/site lant species, and comprising almost 47,000 visits to flowers, as well as records of flowers that were not visited by pollinators, for over 1,000 species and varieties belonging to more than 460 genera and 96 plant families. The more than 650 species of flower visitors belong to 12 orders of invertebrates and four of vertebrates. In this first publication from the project, we present a brief description of the data and make it freely available for any researchers to use in the future, the only restriction being that they cite this paper in the first instance. The data generated from these global surveys will provide scientific evidence to help us understand the role that private gardens (in urban, rural and suburban areas) can play in conserving insect pollinators and identify management actions to enhance their potential.

A framework and case study to systematically identify long‐term insect abundance and diversity datasets
Publisher: Wiley
Date: 13-04-2022
DOI: 10.1111/CSP2.12687
Abstract: Bio ersity is in crisis, and insects are no exception. To understand insect population and community trends globally, it is necessary to identify and synthesize erse datasets representing different taxa, regions, and habitats. The relevant literature is, however, vast and challenging to aggregate. The Entomological Global Evidence Map (EntoGEM) project is a systematic effort to search for and catalogue studies with long‐term data that can be used to understand changes in insect abundance and ersity. Here, we present the overall EntoGEM framework and results of the first completed subproject of the systematic map, which compiled sources of information about changes in dragonfly and damselfly (Odonata) occurrence, abundance, biomass, distribution, and ersity. We identified 45 multi‐year odonate datasets, including 10 studies with data that span more than 10 years. If data from each study could be gathered or extracted, these studies could contribute to analyses of long‐term population trends of this important group of indicator insects. The methods developed to support the EntoGEM project, and its framework for synthesizing a vast literature, have the potential to be applied not only to other broad topics in ecology and conservation, but also to other areas of research where data are widely distributed.
