Within-colony segregation of foraging areas: from patterns to processes
Published: 2022-05-19
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: 2022-05-18
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: 2022-05-12
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: 2022-05-11
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: 2022-05-06
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 [...]
Brain morphology correlates of learning and cognitive flexibility in a fish species (Poecilia reticulata)
Published: 2022-05-03
Subjects: Animal Sciences, Biology, Life Sciences, Zoology
Determining how variation in brain morphology affects cognitive abilities is important to understand inter-individual variation in cognition and, ultimately, cognitive evolution. Yet, despite many decades of research in this area, there is surprisingly little experimental data available from assays that quantify cognitive abilities and brain morphology in the same individuals. Here, we tested [...]
Litter decomposition is moderated by scale-dependent microenvironmental variation in tundra ecosystems
Published: 2022-05-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
1. Tundra soils are one of the world’s largest organic carbon stores, yet this carbon is vulnerable to accelerated decomposition as climate warming progresses. We currently know very little about landscape-scale controls of litter decomposition in tundra ecosystems, which hinders our understanding of the global carbon cycle. 2. Here, we examined how local-scale topography, surface air [...]
Integrating presence-only and presence-absence data to model changes in species geographic ranges: An example of yaguarundí in Latin America
Published: 2022-04-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Anthropogenic changes such as land use and climate change affect species’ geographic ranges, causing range shifts, contractions, or expansions. However, data on range dynamics are insufficient, heterogeneous, and spatially and temporally biased in most regions. Integrated species distribution models (IDMs) offer a solution as they can complement good quality presence-absence data with [...]
High compositional dissimilarity among small communities is decoupled from environmental variation
Published: 2022-04-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Communities composed of small populations are predicted to be strongly influenced by stochastic demographic events and, thus, less affected by environmental selection than those composed of large populations. However, this prediction has only been tested with computer simulations, simplified controlled experiments, and limited observational data. Here, using multiple datasets on fish abundance in [...]
A vegetation carbon isoscape for Australia built by combining continental-scale field surveys with remote sensing
Published: 2022-04-26
Subjects: Life Sciences, Plant Biology, Plant Sciences
Context: Maps of C3 and C4 plant abundance and stable carbon isotope values (δ13C) across terrestrial landscapes are valuable tools in ecology to investigate species distribution and carbon exchange. Australia has a predominance of C4-plants, thus monitoring change in C3:C4 cover and δ13C is essential to national management priorities. Objectives: We applied a novel combination of field surveys [...]
Patterns of selection across gene regulatory networks
Published: 2022-04-26
Subjects: Cell and Developmental Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Gene regulatory networks (GRNs) are the core engine of organismal development. If we would like to understand the origin and diversification of phenotypes, it is necessary to consider the structure of GRNs in order to reconstruct the links between genetic mutations and phenotypic change. Much of the progress in evolutionary developmental biology, however, has occurred without a nuanced [...]
