Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Feeding habits of herbivorous fish play an important role in the form and function of coastal marine ecosystems. Rabbitfishes (Siganidae) have been recognized as important consumers of macroalgae in the coral reefs of the Indo-Pacific region. However, it is unclear how their diet varies among and within species at biogeographical scales. The present study assessed the inter- and intra-specific [...]

In a recent and impressive analysis of avian morphological data (covering >250 000 male birds from 105 species), Youngflesh et al.1 report that birds breeding in North America have become significantly lighter over the last three decades, coincident with rising breeding season temperatures. Because these observations recapitulate predictions under Bergmann’s Rule (i.e., that the body size of [...]

Octocoral Symbiodiniaceae, but not bacterial communities, are resistant to compositional changes from heat stress on a subtropical reef

Rosemary Kate Steinberg, Katherine A Dafforn, Emma L Johnston, et al.

Published: 2023-11-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology

Microbes are essential to the holobiome of all organisms, so when organisms are impacted by environmental stressors the changes to microbial communities can inform on the health state of the host and even cause host disease. In early 2019 marine heatwaves occurred across eastern Australia, resulting in differential bleaching across Lord Howe Island reefs. Here we examined the Symbiodiniaceae and [...]

Sharing the burden: Cabbage stem flea beetle pest pressure and crop damage are lower in rapeseed fields surrounded by other rapeseed crops

Daniel J Leybourne, Antonia M C Pahl, Petra Melloh, et al.

Published: 2023-11-04
Subjects: Agriculture, Entomology, Life Sciences, Other Ecology and Evolutionary Biology

The cabbage stem flea beetle (Psylliodes chrysocephala) is a significant pest of rapeseed (Brassica napus). Feeding by adult P. chrysocephala can cause severe leaf damage and larval infestation can reduce stem strength, both of which impact crop growth and development, causing substantial yield losses and economic damage. The structure of the agricultural landscape can regulate herbivorous pest [...]

Maternal investment and early thermal conditions affect performance and antipredator responses

Maider Iglesias Carrasco, Jiayu Zhang, Daniel W.A. Noble

Published: 2023-10-27
Subjects: Behavior and Ethology, Biology, Evolution, Other Ecology and Evolutionary Biology

Exposure to increased temperatures during early development can lead to phenotypic plasticity in morphology, physiology, and behaviour across a range of ectothermic animals. In addition, maternal effects are known to be important contributors to phenotypic variation in offspring. Whether the two factors interact to shape offspring morphology and behaviour has been barely explored. This is [...]

Functional trait dataset of benthic macroinvertebrates in South Korean streams

Sagar Adhurya, Da-Yeong Lee, Dae-Seong Lee, et al.

Published: 2023-09-22
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology

Functional traits are the result of evolution and adaptation, providing important ecological insights into how organisms interact with their environment. Benthic macroinvertebrates, in particular, have garnered attention as biomonitoring indicators for freshwater ecosystems. This study presents a functional trait dataset for benthic macroinvertebrates, comprising 447 taxa (393 at genus level, 53 [...]

Metaweb and its applications in understanding ecological interactions

Sagar Adhurya, Nisha Agasti, Young-seuk Park

Published: 2023-09-22
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology

Understanding the dynamics of ecological interactions is an essential initial step in acquiring a comprehensive understanding of the ecosystem structure and functions. Such knowledge is pivotal in effective conservation planning, sustainable development, and ecosystem management. However, the limited availability of information on ecological interactions, commonly referred to as Eltonian [...]

KF-metaweb: A trophic metaweb of freshwater ecosystems of South Korea

Sagar Adhurya, Da-Yeong Lee, Young-seuk Park

Published: 2023-09-20
Subjects: Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology

Motivation: The metaweb is a dictionary of nodes and their potential interactions developed for a particular region, focusing on a particular type of ecosystem. Based on the local biodiversity information at different spatial and temporal scales, the regional metaweb can be easily decomposed into local webs. The generated local webs are useful for understanding spatiotemporal variations in [...]

Growth and opportunities for drone surveillance in pinniped research

Pinniped species undergo uniquely amphibious life histories that make them valuable subjects for many domains of research. Pinniped research has often progressed hand-in-hand with technological frontiers of wildlife biology, and drones represent a leap forward for methods of aerial remote sensing, heralding data collection and integration at new scales of biological importance. Drone methods and [...]

Warming summer temperatures are rapidly restructuring North American bumble bee communities

Published: 2023-08-29
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology

A rapidly warming climate is a primary force driving changes in biodiversity worldwide. The impact of warming temperatures on insect communities is of particular interest given their importance for ecosystem function and service provision and the uncertainty around whether insect communities can keep pace with the rate of increasing temperatures. We use a long-term dataset on bumble bee species [...]

The unfulfilled potential of dogs in studying behavioural evolution during the Anthropocene

Christina Hansen Wheat, Clive DL Wynne

Published: 2023-08-07
Subjects: Behavior and Ethology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Zoology

Dogs are an exceptional resource for studying ecological, behavioural and evolutionary processes. However, several widespread misconceptions limit our understanding of dog behaviour and inhibit the use of dogs as model study systems in diverse areas of biological science. These include extensive anthropomorphisation of dog behaviour, a profound bias towards almost exclusively studying pet dogs, a [...]

STRyper: an open source macOS application for microsatellite genotyping

Jean Peccoud

Published: 2023-07-29
Subjects: Biodiversity, Bioinformatics, Molecular Genetics, Other Ecology and Evolutionary Biology

In the context of population genetics, microsatellite markers analyzed by capillary sequencing remain useful tools for quick genotyping and low-cost studies. This contrasts with the lack of a free application to analyze chromatograms for microsatellite genotyping that is designed for population geneticists. To fill this gap, I have developed STRyper, a macOS application whose source code is [...]

How does dispersal shape the genetic patterns of animal populations in European cities? A simulation approach

Paul Savary, Cécile Tannier, Jean-Christophe Foltête, et al.

Published: 2023-07-25
Subjects: Biodiversity, Genetics, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology

Context and objectives Although urbanization is a major driver of biodiversity erosion, it does not affect all species equally. The neutral genetic structure of populations in a given species is affected by both genetic drift and gene flow processes. In cities, the size of animal populations determines drift and can depend on multiple processes whereas gene flow essentially depends on the [...]

The killing of a runner in Northern Italy by a brown bear (Ursus arctos arctos) and the subsequent investigation of such matter highlighted a Human-Wildlife Conflict (HWC) that has been present in Trentino since the introduction of bears for conservation during the Life Ursus Project. Such conflict may be exacerbated as both human and bear populations get bigger. In this paper, I summarize the [...]
