Evolution and impact of socially transferred materials
Published: 2022-05-27
Subjects: Animal Sciences, Biodiversity, Bioinformatics, Cell and Developmental Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Physiology, Systems Biology
Since the dawn of life, transfers of metabolized material between individuals have led to great innovations of evolution. When metabolized material is transferred from one individual’s body to another (as with sperm, eggs, milk, symbionts), secondary manipulative molecules that induce a physiological response in the receiver are often transferred along with the primary cargo. The bioactive and [...]
The role of climate change and niche shifts in divergent range dynamics of a sister-species pair
Published: 2022-05-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Species ranges are set by limitations in factors including climate tolerances, habitat use, and dispersal abilities. Understanding the factors governing species range dynamics remains a challenge that is ever more important in our rapidly changing world. Species ranges can shift if environmental changes affect available habitat, or if the niche or habitat connectivity of a species changes. We [...]
One hand washes the other: cooperation and conflict in hygiene and immunity
Published: 2022-05-25
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In humans and wild animals, pathogens impose costs on both the individual and the social group as a whole. To minimise these costs, group-living species have evolved many hygienic and immune traits that benefit from cooperation between individuals, thereby subjecting them to the laws of social evolution. Such social contracts include reciprocal grooming, altruistic self-isolation, spiteful [...]
GridDER: Grid Detection and Evaluation in R
Published: 2022-05-23
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics
Observations and collections of organisms form the basis of our understanding of Earth’s biodiversity and are an indispensable resource for global change studies. Geographic information is key, serving as the link between organisms and the environments they reside in. However, the geographic information associated with these records is often inaccurate, thus limiting their efficacy for research. [...]
A robust and readily implementable method for the meta-analysis of response ratios with and without missing standard deviations
Published: 2022-05-19
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The log response ratio, lnRR, is the most frequently used effect size statistic for meta-analysis in ecology. However, often missing standard deviations (SDs) prevent estimation of the sampling variance of lnRR. We propose new methods to deal with missing SDs via a weighted average coefficient of variation (CV) estimated from studies in the dataset that do report SDs. Across a suite of simulated [...]
Brood thermoregulation effectiveness is positively linked to the amount of brood but not to the number of bees in honeybee colonies
Published: 2022-05-18
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
To ensure the optimal development of brood, a honeybee colony needs to regulate its temperature within a certain range of values (thermoregulation), regardless of environmental changes in biotic and abiotic factors. While the set of behavioural and physiological responses implemented by honeybees to regulate the brood temperature has been well studied, less is known about the factors that may [...]
Within-colony segregation of foraging areas: from patterns to processes
Published: 2022-05-18
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
Spatial segregation of foraging areas among conspecifics breeding in different colonies has been observed in several colonial vertebrates and is assumed to originate from competition and information use. Segregation between sub-groups of foraging animals from the same colony (hereafter sub-colonies) has comparatively received limited attention, even though it may have strong impacts on colony [...]
A Systematic Map of Research Exploring the Ecological Modifiers and Consequences of Bark Damaging Behaviour in Squirrel Species
Published: 2022-05-17
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Zoology
Bark-stripping and browsing by mammals in woodlands can cause widespread damage to trees, inhibiting tree growth and leading to whole tree or canopy death. Sciurid species worldwide are known to incorporate inner bark or cambium tissue into their diets, and outer bark can additionally be used as nesting material. The drivers and causes of bark-stripping behaviour have been investigated and [...]
Warmer springs lead to earlier and higher peaks of arboreal caterpillars
Published: 2022-05-14
Subjects: Ecology and Evolutionary Biology, Life Sciences
Advances in spring phenology are among the clearest biological responses to climate warming. In the ephemeral temperate deciduous forest food webs, at the vanguard of research on temperature’s effect on trophic interactions, most work has focused on the average timing of phenological events. In comparison, effects of temperature on the abundance of individuals and their seasonal spread is [...]
Animating the carbon cycle through trophic rewilding could provide highly effective natural climate solutions
Published: 2022-05-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Natural climate solutions are being advanced as cost-effective and safe ways to achieve net-zero emissions by protecting and enhancing carbon capture and storage in plants, and in soils and sediments in terrestrial and marine ecosystems. Current thinking holds that these solutions have the added benefit of protecting habitats and landscapes to restore and conserve animal species diversity. [...]
Notes from the Past Show How Local Variability can Stymie Urchins and the Rise of the Reds in the Gulf of Maine
Published: 2022-05-10
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
The impacts of global change — from shifts in climate to overfishing to land use change — can depend heavily on local abiotic context. Building an understanding of how to downscale global change scenarios to local impacts is often difficult, however, and requires historical data across large gradients of variability. Such data are often not available — particularly in peer reviewed or gray [...]
Macroecological processes drive spiritual ecosystem services obtained from giant trees
Published: 2022-05-07
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Social and Behavioral Sciences, Sociology, Sociology of Religion
Giant trees that have come to have their own unique identities are often named by local people and can inspire a sense of awe and become objects of faith. Although these giant trees provide various kinds of spiritual ecosystem services that are beneficial to the spiritual well-being of the human society, the drivers of these services remain unclear. Using structural equation modeling with 38,994 [...]
Fine-scale spatial distribution of biodiversity citizen science in a natural area depends on area accessibility and differs from other recreational area use
Published: 2022-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
1. Opportunistic citizen science produces large amounts of primary biodiversity data but is underutilized in the conservation and management of protected areas despite these areas’ status as citizen science hotspots. Application of these data may be limited by the challenge of understanding sampling patterns associated with opportunistic data at a scale relevant to local area management. An [...]
Synchrony in adult survival is remarkably strong among common temperate songbirds across France
Published: 2022-05-03
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Synchronous variation in demographic parameters across species destabilizes populations, metapopulations and metacommunities and increases extinction risks. Revealing the processes that synchronize population dynamics across species allows to identify trans-specific demographic processes that are subject to environmental forcing of overarching importance. Using a Bayesian, hierarchical [...]
Community-sourced sightings of atypical birds can be used to understand the evolution of plumage color and pattern
Published: 2022-05-03
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Birds are known for their brilliant colors and extraordinary patterns. Sightings of individuals with atypical plumage often cause considerable excitement in the birding public, but receive little attention beyond reporting one-off sightings by the scientific community. In this perspective, we argue that sightings of individuals with atypical plumage submitted to community science platforms hold [...]
