Accounting for cloud cover and circannual variation puts the effect of lunar phase on deer-vehicle collisions into perspective
Published: 2022-11-22
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology
Although several studies have focused on the influence of moonlight over deer-vehicle collisions, findings have been inconsistent. This may be due to neglecting the effects of cloud cover, a major impediment to moon illumination, and circannual variation in both deer and human activity. We modeled how median cloud cover interacted with the illuminated fraction of the moon in affecting daily roe [...]
A tale of two genomes: What drives mitonuclear discordance in asexual lineages of a freshwater snail?
Published: 2022-11-21
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
We use genomic information to tell us stories of evolutionary origins. But what does it mean when different genomes report wildly different accounts of lineage history? This “discordance” can be a consequence of a fascinating suite of natural history and evolutionary phenomena, from the different inheritance mechanisms of nuclear vs. cytoplasmic genomes to hybridization and introgression to [...]
Morphological plasticity in a caddisfly that co-occurs in lakes and streams
Published: 2022-11-18
Subjects: Ecology and Evolutionary Biology, Life Sciences
Lake and stream fauna are frequently studied, yet surprisingly little is known about ecological and evolutionary dynamics of species that inhabit both lentic and lotic habitats. There are few examples of species co-occurring in the different habitat flow types, which raises questions on how this may impact their ability to adapt to changing climatic conditions. The aquatic insect Limnephilus [...]
Misrepresenting biases in arrival: a comment on Svensson (2022)
Published: 2022-11-17
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
The idea that adaptive change is subject to biases in variation by a "first come, first served" dynamic is not part of classic evolutionary reasoning. Yet, predictable effects of biases in the introduction of variation have been reported in models of population genetics, in laboratory evolution, and in retrospective analyses of natural adaptation. This effect of "arrival bias" has potentially [...]
The cost of being a non-native English speaker in science
Published: 2022-11-10
Subjects: Biodiversity, Ecology and Evolutionary Biology, International and Intercultural Communication, Publishing, Scholarly Publishing
The use of English as the common language of science represents a major impediment to maximising the contribution of non-native English speakers to science. Yet few studies have quantified the consequences of language barriers on the career development of researchers who are non-native English speakers. Our survey demonstrates that non-native English speakers, especially early in their careers, [...]
Space-for-time substitutions in climate change ecology and evolution
Published: 2022-11-10
Subjects: Ecology and Evolutionary Biology
In an epoch of rapid environmental change, understanding and predicting how biodiversity will respond to a changing climate is an urgent challenge. Since we seldom have sufficient long-term biological data to use the past to anticipate the future, spatial climate-biotic relationships are often used as a proxy for predicting biotic responses to climate change over time. These ‘space-for-time [...]
Heritability and developmental plasticity of growth in an oviparous lizard
Published: 2022-11-09
Subjects: Ecology and Evolutionary Biology
Selective processes act on phenotypic variation although the evolutionary potential of a trait relies on the underlying heritable variation. Developmental plasticity is an important source of phenotypic variation, but it can also promote changes in genetic variation, yet we have a limited understanding on how they are both impacted. Here, we quantified the influence of developmental temperature [...]
Evolutionary origins of the Mesoamerican-eastern United States floristic disjunction: current status and future prospects
Published: 2022-11-07
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Sciences
Biogeographic disjunction patterns, where multiple taxonomic groups are shared between isolated geographic areas, represent excellent systems for investigating the historical assembly of modern biotas as well as fundamental biological processes such as speciation, diversification, niche evolution, and evolutionary responses to climate change. Studies on plant genera disjunct across the Northern [...]
The Fieldwork Wellness Framework: A new approach to field research in Ecology
Published: 2022-11-07
Subjects: Biology, Ecology and Evolutionary Biology
Fieldwork is often an important aspect of research in Ecology, Evolution, and Conservation Biology (EECB), but individuals with marginalized identities are likely to experience compromised wellness. The responsibility for structurally changing fieldwork to improve experiences and outcomes falls on the entire EECB community. We propose a Fieldwork Wellness Framework to replace traditional [...]
Iterative species distribution modeling results in the discovery of novel populations of a rare cold desert perennial
Published: 2022-11-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Niche modeling for rare and range-restricted species can generate inaccurate predictions leading to an overestimation of a species geographic distribution. We used an iterative ensemble modeling approach and model-stratified field surveys to improve niche model formulation and better understand the ecological drivers of Ivesia webberi distribution. I. webberi is a U.S. federally threatened [...]
Temperate-tropical transitions are linked with shifts in the structure of evolutionary integration in Vitaceae leaves
Published: 2022-11-01
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity. The strength, scale, and structure of integration may constrain or catalyze evolution in the face [...]
Behavioral plasticity allows ungulates to balance risk and reward following megafire
Published: 2022-10-29
Subjects: Ecology and Evolutionary Biology
Anthropogenic climate and land use change has accelerated the frequency of extreme climatic disturbances such as megafire. These megafires dramatically alter ecosystems and threaten the long-term conservation of economically and ecologically important species, including native ungulates. Recent work suggests that ungulate species may be able to adjust to the immediate effects of megafire by [...]
A globally integrated structure of taxonomy supporting biodiversity science and conservation
Published: 2022-10-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
All aspects of biodiversity research, from taxonomy to conservation, rely on data associated with species names. Effective integration of names across multiple fields is paramount and depends on coordination and organization of taxonomic data. We assess current efforts and find that even key applications for well-studied taxa still lack commonality in taxonomic information required for [...]
Beyond genes-for-behaviour: the potential for genomics to resolve questions in avian brood parasitism
Published: 2022-10-27
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Brood parasite-host interactions are among the most easily observable and amenable natural laboratories of antagonistic coevolution, and as such have intrigued evolutionary biologists for decades. It is therefore surprising they have not been at the forefront of genomic studies on evolutionary adaptation. Here we review state-of-the-art molecular methods in studying avian brood parasitism, a [...]
Deep reticulation: the long legacy of hybridization in vascular plant evolution
Published: 2022-10-26
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Biology, Plant Sciences
Hybridization has long been recognized as a fundamental evolutionary process in plants, but our understanding of its phylogenetic distribution and biological significance across deep evolutionary scales has been largely obscure—until recently. Over the past decade, genomic and phylogenomic datasets have revealed, perhaps not surprisingly, that hybridization, often associated with polyploidy, has [...]
