Herodotools: An R package to integrate macroevolution, community ecology, and biogeography
Published: 2022-07-05
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
Aim: Historical processes like speciation, extinction, and historical dispersal are the ultimate factors generating and maintaining biodiversity in space and time. While detecting the effect of those processes on the distribution of biodiversity has great relevance by itself, how to measure them is critical to interpreting the underlying causes of biological patterns. However, metrics of [...]
The coevolutionary mosaic of bat betacoronavirus emergence risk
Published: 2022-07-01
Subjects: Biodiversity, Bioinformatics, Biology, Biotechnology, Cell and Developmental Biology, Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences
Pathogen evolution is one of the least predictable components of disease emergence, particularly in nature. Here, building on principles established by the geographic mosaic theory of coevolution, we develop a quantitative, spatially-explicit framework for mapping the evolutionary risk of viral emergence. Driven by interest in diseases like SARS, MERS, and COVID-19, we examine the global [...]
The vocal apparatus of bats: an understudied tool to reconstruct the evolutionary history of echolocation?
Published: 2022-06-12
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Zoology
Until recently, bat phylogeny separated megabats (laryngeally non-echolocators) and microbats (all laryngeal echolocators) into two distinct clades. This segregation was consistent with the assumption that laryngeal echolocation was acquired by a common ancestor and inherited by all microchiropterans. Thus, laryngeal echolocation was regarded to have evolved once. Recent advances in bat genome [...]
Best practices for LGBTQ+ inclusion during ecological fieldwork: Considering safety, cis/heteronormativity, and structural barriers
Published: 2022-05-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Lesbian, gay, bisexual, trans, queer, and other marginalized gender and sexual identities (LGBTQ+) face unique barriers to participation in applied ecology. Such barriers are particularly relevant during fieldwork, including physical and discriminatory risks, increased isolation, and non-inclusive infrastructure.To be more inclusive, fieldwork should address LGBTQ+ safety and survival needs. [...]
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 [...]
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 [...]
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 [...]
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 [...]
Are we underestimating the ecological and evolutionary effects of warming? Interactions with other environmental drivers may increase species vulnerability to high temperatures
Published: 2022-04-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Warming, the most prominent aspect of global environmental change, already affects most ecosystems on Earth. In recent years, biologists have increasingly integrated the effects of warming into their models by capturing how temperature shapes their physiology, ecology, behavior, evolutionary adaptation, and probability of extirpation/extinction. The more physiologically-grounded approaches to [...]
Surprising Abundant Mussel Beds in the Center of Boston Harbor in the Midst of a Regional Die-Back
Published: 2022-04-05
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Mussel beds in the rocky intertidal of New England have long been a paradigmatic example of how physical forces – wave action – reduces predator abundance and enables a distinct ecological community. These beds, however, have witnessed a precipitous >60% decline since the 1970s for currently unknown reasons. Here we report on the surprising persistence of large dense mussel beds in the middle [...]
Reducing the biases in false correlations between discrete characters
Published: 2022-04-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
The correlation between two characters is often interpreted as evidence that there exists a significant and biologically important relationship between them. However, Maddison and FitzJohn (2015) recently pointed out that in certain situations find evidence of correlated evolution between two categorical characters is often spurious, particularly, when the dependent relationship stems from a [...]
Urban food forestry transforms fine-scale soil function for rapid and uniform carbon sequestration
Published: 2022-03-21
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Urbanization displaces agriculture and natural ecosystems, constraining food security and carbon (C) sinks. A proposed solution, Urban Food Forestry (UFF), promises local food from trees that can sequester C faster than other land cover types as long as soil function improves. We compared fine-scale variation in soil physical, chemical and biological properties within and between UFF and [...]
Summer temperature – but not growing season length – influences radial growth of Salix arctica in coastal Arctic tundra
Published: 2022-03-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Arctic climate change is leading to an advance of plant phenology (the timing of life history events) with uncertain impacts on tundra ecosystems. Although the lengthening of the growing season is thought to lead to increased plant growth, we have few studies of how plant phenology change is altering tundra plant productivity. Here, we test the correspondence between 14 years of Salix arctica [...]
Acute blood parasite infections induce moderate physiological costs in juvenile raptor hosts
Published: 2022-02-24
Subjects: Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Other Ecology and Evolutionary Biology, Parasitology
Parasites trigger reactions in hosts, leading to suppressive resistance and/or tolerance, aiming to limit the parasitic costs. Both colonization by parasites and defense activation can induce varying amount of costs for the host. Understanding parasite-induced effects on host fitness crucially depends on assessing parasitic costs in specific wild host-parasite systems. To evaluate potential [...]
Systemic racism alters wildlife genetic diversity
Published: 2022-02-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Humans are the defining feature of urban ecosystems. In the United States, systemic racism has had lasting effects on the structure of cities, specifically due to government-mandated “redlining” policies that produced racially segregated neighborhoods that persist today. However, it is not known whether varying habitat structure and natural resource availability associated with racial segregation [...]
