Disentangling variational bias: the roles of development, mutation and selection

Haoran Cai, David Des Marais, Diogo Melo

Published: 2024-07-20
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology

The extraordinary diversity and adaptive fit of organisms to their environment depends fundamentally on the availability of variation. While many evolutionary studies assume that random mutations produce isotropic phenotypic variation, the distribution of variation available to natural selection is more restricted, as the distribution of phenotypic variation is affected by a range of factors in [...]

Repeatability and intra-class correlations from time-to-event data: towards a standardized approach

Many biological features are expressed as “time-to-event” traits, such as time to first reproduction or response to some stimulus. The analysis of these traits frequently produces right-censored data in cases where no event has occurred within a certain timeframe. The Cox proportional hazards (CPH) model, a type of survival analysis, accounts for censored data by estimating the hazard of an event [...]

Scanning the skies for migrants: Conservation-focused opportunities for a pan-European automated telemetry network

Accelerated biodiversity loss during the Anthropocene has destabilised functional links within and between ecosystems. Migratory species that cross different ecosystems on their repeated journeys between breeding and non-breeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem-specific threats. As these bring both lethal and non-lethal [...]

Social ageing varies within a population of bottlenose whales

Sam Froman Walmsley, Laura J Feyrer, Claire Girard, et al.

Subjects: Behavior and Ethology, Evolution, Other Ecology and Evolutionary Biology

How social behaviour changes as individuals age has important consequences for the health and function of both human and non-human societies. However, the extent of inter-individual variation in social ageing has been underappreciated, especially in natural populations of animals. Here, we leverage a photo-identification dataset spanning 35 years to examine social ageing in an Endangered [...]

Detection of energetic equivalence depends on food web architecture and estimators of energy use

Poppy Joaquina Romera, Benoit Gauzens, Ana Carolina Antunes, et al.

Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology

Ecologists have long debated the universality of the energetic equivalence rule (EER), which posits that population energy use should be invariant with average body size due to negative size–density scaling. We explored size–density and size–energy use scaling across 183 geographically–distributed soil invertebrate food webs to investigate the universality of these fundamental EER assumptions. [...]

Topoclimate buffers floristic diversity from macroclimate in temperate mountain forests.

Microclimates strongly influence the composition and diversity of forest plant communities. Recent studies have highlighted the role of tree canopies in shaping understory thermal conditions at small spatial scales, especially in lowland forests. In mountain forests, however, the influence of topography in environmental conditions (e.g. topoclimate) is ought to also influence plants’ perceived [...]

From eggs to adulthood: sustained effects of early developmental temperature and corticosterone exposure on physiology and body size in an Australian lizard

Ondi Crino, Kristoffer H Wild, Christopher R. Friesen, et al.

Subjects: Biochemistry, Biophysics, and Structural Biology, Biology, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology

As global temperatures continue to rise due to climate change, developing animals may be increasingly exposed to elevated temperatures. Additionally, elevated temperatures could affect developing animals through indirect effects such as increased exposure to maternal glucocorticoid hormones. Exposure to elevated levels of glucocorticoids during development can have immediate and sustained effects [...]

Although diverse perspectives are fundamental for fostering and advancing science, power relations have limited the development, propagation of ideas, and recognition of minority groups in academia. Gender bias is one of the most well-documented processes, leading women to drop out of their academic careers due to fewer opportunities and lower prestige. Using long-term data (2008-2019) on talks [...]

Light Pollution at Sea: Implications and Potential Hazards of Human Activity for Offshore Bird and Bat Movements in the Greater North Sea

Human activity in the North Sea is intensifying, as emerging uses, such as offshore wind farms (OWFs) and liquid natural gas (LNG) terminals, are added to fishing, freight shipping and fossil fuel production as traditional forms of resource exploitation. The volume and scale of these additional installations are projected to increase substantially in the coming decades, which amplifies the need [...]

Quantifying intermediary processes in ecology using causal mediation analyses

Hannah E Correia, Laura E Dee, Paul J Ferraro

Subjects: Applied Statistics, Longitudinal Data Analysis and Time Series, Other Ecology and Evolutionary Biology, Statistical Methodology

Ecologists seek to understand the intermediary ecological processes through which changes in one attribute in a system affect other attributes. Yet, quantifying the causal effects of these mediating processes in ecological systems is challenging. Researchers must define what they mean by a “mediated effect”, determine what assumptions are required to estimate mediation effects without bias, and [...]

Global review of shorebird tracking publications: Gaps and priorities for research and conservation

Electronic tracking has enabled rapid advances in knowledge of the movement behaviour and habitat use of shorebirds (Charadriiformes), and is thus making a growing contribution to their conservation. However, developing a useful coherent global strategy for tracking these taxa requires an overview of the current availability of data and how it varies along regional and ecological lines. To this [...]

Toxic baiting is used for the lethal control of mammalian predators. It is easily applied over large areas and can be highly effective, but also receives significant criticism. We conducted a meta-analysis of the efficacy of lethal baiting for the feral cat, red fox and dingo; our outcome of interest was predator survival. Our dataset contained 125 effects from 35 studies, comprising 1560 [...]

Cryptic species and hybridisation in corals: challenges and opportunities for conservation and restoration

Cynthia Riginos, Iva Popovic, Zoe Meziere, et al.

Subjects: Genomics, Marine Biology, Other Ecology and Evolutionary Biology

Conservation and management of coral reef ecosystems will depend on accurate assessments of reef-building coral species diversity. However, the true diversity of corals may be obfuscated by the presence of cryptic species, which are likely much more pervasive than is currently recognised. Additionally, cryptic species may sometimes hybridize, resulting in gene introgression between species. Here, [...]
