Natural selection is less efficient at species range edges

Chloé Schmidt, Jussi Mäkinen, Jean-Philippe Lessard, et al.

Published: 2023-12-06
Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences

Changing species distributions due to global change underscore a pressing need to better understand range limits. However, our knowledge of general determinants of range limits remains poor despite over a century of work. Theoretical models demonstrate that genetic drift should strengthen across environmental gradients. This can limit natural selection to the point where populations can no longer [...]

Escape tendency and the mobility behavior of four alpine rodents do not change with altitude

Jacopo Cerri, Ilaria Melcore, Noemi Gargano, et al.

Subjects: Ecology and Evolutionary Biology, Integrative Biology, Zoology

Behavioural responses are particularly important to quantify species-specific habitat influences on natural selection. Mountains, with their wide range of habitats, can be regarded as a valuable context where the environmental conditions influence animal behaviour. We studied the inter-specific variation in the escape tendency and the mobility behaviour in four alpine rodents’ species, a bank [...]

Functional coherence among miRNA targets: a potential metric for assessing biological signal among target prediction methods in non-model species

Christopher Wheat, Rachel A. Steward, Yu Okamura, et al.

Published: 2023-11-30
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Although miRNA regulation of protein production is a likely target of adaptive evolution, high false-positive rates in the identification of mRNAs targeted by miRNAs in non-model species’ complicates interpretation of recent advances. Here we document the challenges and then outline steps for the community to address these challenges.

Vocal Dimorphism in Anna’s Hummingbirds

Whereas vocal sexual dimorphism is widespread amongst birds, it has been historically overlooked in non-passerines such as hummingbirds. By evaluating correlations among sex, behaviors, and vocalizations, the meaning and utility of intentional sound production may be inferred. Anna's Hummingbirds (Calypte anna) exhibit pronounced sexual dimorphism, with males being larger and having more vibrant [...]

Opinion: Missing half the picture, focus on stony corals during bleaching events has left critical knowledge gaps in our understanding of reef-scale bleaching and recovery

Honest Signalling Made Simple

Jacob Chisausky, Carl Bergstrom, Kevin Zollman, et al.

Published: 2023-11-24
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences

Honest communication is a common phenomenon in animal behaviour, and is frequently explained by appeal to the so-called handicap hypothesis by which signal costs deter dishonesty. However, the handicap models commonly used to explain honest signalling have has been subject to several lines of criticism in recent literature. This trend may have led researchers outside of the field of animal [...]

Measuring biological generality in meta-analysis: a pluralistic approach to heterogeneity quantification and stratification

Yefeng Yang, Daniel W.A. Noble, Rebecca Spake, et al.

Published: 2023-11-24
Subjects: Ecology and Evolutionary Biology, Statistics and Probability

Uncovering general rules enhances the predictive capabilities in ecology and evolution. Meta-analytic approaches play a critical role in this endeavour, examining the extent to which phenomena can be replicated, generalized, and transferred. However, ecologists and evolutionary biologists have largely overlooked the role of meta-analytic heterogeneity in informing generality. To reform this [...]

Amazonian soundscapes: unravelling the secrets of insect acoustic niches in diverse habitats

Leandro Do Nascimento, Cristian Pérez-Granados, Janderson B. Rodrigues Alencar, et al.

Published: 2023-11-22
Subjects: Ecology and Evolutionary Biology

Insects are the most diverse animal taxon on Earth and play a key role in ecosystem functioning. However, they are often neglected from biodiversity surveys due to the difficulties of monitoring this small and hyper-diverse taxon. With technological advancements in biomonitoring and analytical methods, these shortcomings may finally be addressed. Here, we performed passive acoustic monitoring at [...]

Local and regional processes drive distance decay in structure in a spatial multilayer plant-pollinator network

Agustin Vitali, Maya Goldstein, Matan Markfeld, et al.

Published: 2023-11-21
Subjects: Ecology and Evolutionary Biology, Life Sciences

Understanding spatial variation in species distribution and community structure is at the core of biogeography and community ecology. Nevertheless, the effect of distance on metacommunity structure remains little studied. We use plant-pollinator network data from the Canary Islands to examine how plant-pollinator community structure changes across geographical distances at a regional scale and [...]

Covariance reaction norms: A flexible approach to estimating continuous environmental effects on quantitative genetic and phenotypic (co)variances

Published: 2023-11-21
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Genetics, Integrative Biology, Life Sciences, Population Biology, Research Methods in Life Sciences, Zoology

Estimating quantitative genetic and phenotypic (co)variances plays a crucial role in investigating key evolutionary ecological phenomena, such as developmental integration, life history tradeoffs, and niche specialization, as well as in describing selection and predicting multivariate evolution in the wild. While most studies assume (co)variances are fixed over short timescales, environmental [...]

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 [...]

Rare, but potentially impactful, extreme events in socio-ecological systems (SES) can trigger significant consequences. The scarcity of theoretical frameworks for such events in SES is due to data limitations and difficulty in building coupled SES models. We explore the effect of extreme events on coupled socio-ecological systems using two stylized case studies: harvesting of old-growth forests [...]

The Pangolin Universal Notching System (PUNS): A Foundational Scale Marking Methodology for Pangolins

Subjects: Ecology and Evolutionary Biology, Zoology

Abstract Due to significant anthropogenic pressures, all eight established species of pangolin are listed on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the highest level of international protection possible. Pangolin population status assessments are incomplete, particularly in areas with high exploitation and limited field assets. [...]

Forecasting insect dynamics in a changing world

Christie A Bahlai

Published: 2023-11-16
Subjects: Ecology and Evolutionary Biology, Entomology

Predicting how insects will respond to stressors through time is difficult because of the diversity of insects, environments, and approaches used to monitor and model. Forecasting models take correlative/statistical, mechanistic models, and integrated forms; in some cases, temporal processes can be inferred from spatial models. Because of heterogeneity associated with broad community [...]
