Major taxa studied: Virtual plant species. Location: Abruzzo (Italy). Time period: Timeless (simulated data). Methods: We simulated the occurrence of two virtual species with different ecology (generalist vs specialist) and [...]
Bird Eye Color: A Rainbow of Variation, a Spectrum of Explanations
Published: 2022-08-24
Subjects: Ecology and Evolutionary Biology, Life Sciences
Birds display a rainbow of eye colors, but this trait has received relatively little study compared to plumage coloration. Avian eye color variation occurs at all phylogenetic scales: it can be conserved throughout whole families or vary within a single species, yet the evolutionary importance of eye color variation within species and across the avian phylogeny is also understudied. Here, we [...]
The promise of an evolutionary perspective of alcohol consumption
Published: 2022-08-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Medicine and Health Sciences, Neuroscience and Neurobiology, Other Ecology and Evolutionary Biology, Other Life Sciences, Pharmacology, Toxicology and Environmental Health
The urgent need for medical treatments of alcohol use disorders has motivated the search for novel molecular targets of alcohol response. Most studies exploit the strengths of lab animals without considering how these and other species may have adapted to respond to alcohol in an ecological context. Here, we provide an evolutionary perspective on the molecular and genetic underpinnings of alcohol [...]
A test of species’ mobility hypothesis in ecological niche modeling
Published: 2022-08-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Abstract Aim: Ecological niche model (ENM) or species distribution model is a modeling technique broadly used in ecology and biogeography and is increasingly used in decision-making regarding land use and biodiversity conservation. The methodology behind ENM applications is critical for model accuracy. One critical question that every ENM study faces is how to define a model training area. [...]
Curated dataset of accessible and recreational parks in the U.S.: Comparison to greenspace metrics and sociodemographics
Published: 2022-08-23
Subjects: Epidemiology, Medicine and Health Sciences, Public Health
Most spatial epidemiological studies of nature-health relationships use generalized green space measures. For instance, coarse resolution spatial data containing normalized difference vegetative index (NDVI) values are prominent despite criticisms, such as the researcher’s inability to restrain exposure estimates to public (accessible) and private (largely inaccessible) land. Non-threatening [...]
The Risk of Avian Influenza in the Southern Ocean: A practical guide
Published: 2022-08-22
Subjects: Animal Sciences, Biology, Immunology and Infectious Disease, Life Sciences
Advice from Avian Influenza experts suggests that there is a high risk that Highly Pathogenic Avian Influenza will arrive in the Southern Ocean 2022/23-2024/25 austral summers. Since the beginning of 2022, the increasing intensity of highly pathogenic avian influenza (HPAI) H5N1 outbreaks has resulted in the death of hundreds of thousands of seabirds in the Northern Hemisphere, around the [...]
Dog days are over: climate change is predicted to cause population collapse in a cooperative breeder
Published: 2022-08-17
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
It has been suggested that animals may have evolved co-operative breeding strategies in response to extreme climatic conditions. Climate change, however, may push species beyond their ability to cope with extreme climates, and reduce the group sizes in co-operatively breeding species to a point where populations are no longer viable. Predicting the impact of future climates on these species is [...]
The Darwinian Core of Evolutionary Theory and the Extended Evolutionary Synthesis: Similarities and Differences
Published: 2022-08-13
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
In this paper, we evaluate debates surrounding calls for an Extended Evolutionary Synthesis in light of the Darwinian core of evolutionary theory, which was somewhat broader than the Modern Synthesis. We suggest that Darwin’s nuanced operationalization of natural selection rested upon two innovations: the atomization of individuals into trait-variants, and a reconceptualization of heredity in [...]
Bayesian reinforcement learning models reveal how great-tailed grackles improve their behavioral flexibility in serial reversal learning experiments
Published: 2022-08-10
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Environments can change suddenly and unpredictably and animals might benefit from being able to flexibly adapt their behavior through learning new associations. Serial (repeated) reversal learning experiments have long been used to investigate differences in behavioral flexibility among individuals and species. In these experiments, individuals initially learn that a reward is associated with a [...]
Beyond "bluespace" and "greenspace": A narrative review of possible health benefits from exposure to other natural landscapes
Published: 2022-08-10
Subjects: Environmental Public Health, Medicine and Health Sciences, Public Health
Numerous studies have highlighted the physical and mental health benefits of contact with nature, typically in landscapes characterized by plants (i.e., “greenspace”) and water (i.e., “bluespace”). However, natural landscapes are not always green or blue, and the effects of other landscapes are worth attention. This narrative review attempts to overcome this limitation of past research. Rather [...]
Genomic architecture of resistance and tolerance to Swiss needle cast and Rhabdocline needle cast diseases in Douglas-fir
Published: 2022-08-10
Subjects: Genetics and Genomics, Life Sciences, Molecular Genetics
Understanding the genetic architecture of tolerance and resistance to pathogens is important to monitor and maintain resilient tree populations. Here we investigate the genetic basis of tolerance and resistance and to needle cast disease in Douglas-fir (Pseudotsuga menziesii) caused by two fungal pathogens: Swiss needle cast (SNC) caused by Nothophaeocryptopus gaeumannii, and Rhabdocline needle [...]
Repeatability of performance within and across contexts measuring behavioral flexibility
Published: 2022-08-10
Subjects: Animal Experimentation and Research, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
Research into animal cognitive abilities is increasing quickly and often uses methods where behavioral performance on a task is assumed to represent variation in the underlying cognitive trait. However, because these methods rely on behavioral responses as a proxy for cognitive ability, it is important to validate that the task structure does, in fact, target the cognitive trait of interest [...]

The IUCN Red List is not sufficient to protect genetic diversity
Published: 2022-08-01
Subjects: Ecology and Evolutionary Biology, Life Sciences
The International Union for Conservation of Nature (IUCN) Red List is an important and widely used conservation prioritization tool. It uses information about species range size, habitat quality and fragmentation levels, and trends in abundance to assess species extinction risk. Genetic erosion is an additional key factor determining extinction risk, but the Red List was not designed to assess [...]
