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 [...]
Blood parasite infection causes marginal temporary costs in juvenile birds of prey
Published: 2022-02-24
Subjects: Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Other Ecology and Evolutionary Biology, Parasitology
Physiological costs from parasites arise from host colonization and defence activation and can vary according to the interactions of host and parasite traits and states. Parasite-induced costs crucially differ between stages of infection, but this is difficult to assess in wild vertebrates. To evaluate the effects of blood parasite infection in juvenile birds, we compared physiological measures [...]
Systemic racism alters wildlife genetic diversity
Published: 2022-02-19
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 [...]
Density dependence and disease dynamics: moving towards a predictive framework
Published: 2022-02-16
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
High population density is thought to exacerbate parasite exposure rates, leading to increased transmission and greater disease burdens. Different types of interactions exhibit different relationships with density, and therefore so do parasites that are spread by these interactions. Epidemiological models often assume a given density-transmission relationship, and the validity of this assumption [...]
Mismatch between IUCN range maps and species interactions data illustrated using the Serengeti food web
Published: 2022-02-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Background. Range maps are a useful tool to describe the spatial distribution of species. However, they need to be used with caution, as they essentially represent a rough approximation of a species’ suitable habitats. When stacked together, the resulting communities in each grid cell may not always be realistic, especially when species interactions are taken into account. Here we show the extent [...]
Inferring trends in pollinator distributions across the Neotropics from publicly available data remains challenging despite mobilisation efforts
Published: 2022-01-24
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Aim: Aggregated species occurrence data are increasingly accessible through public databases for the analysis of temporal trends in species’ distributions. However, biases in these data present challenges for robust statistical inference. We assessed potential biases in data available through GBIF on the occurrences of four flower-visiting taxa: bees (Anthophila), hoverflies (Syrphidae), [...]
Plant community data from a statewide survey of paired serpentine and non-serpentine soils in California, USA
Published: 2022-01-14
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Soils derived from ultramafic parent materials (hereafter serpentine) provide habitat for unique plant communities containing species with adaptations to the low nutrient levels, high magnesium: calcium ratios, and high metal content (Ni, Zn) that characterize serpentine. Plants on serpentine have long been studied in evolution and ecology, and plants adapted to serpentine contribute [...]
Molecular Paleobiology of the Echinoderm Skeleton
Published: 2022-01-10
Subjects: Cell and Developmental Biology, Developmental Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Molecular paleobiology provides a promising avenue to merge data from deep time, molecular biology and genomics, gaining insights into the evolutionary process at multiple levels. The echinoderm skeleton is a model for molecular paleobioloogical studies. I begin with an overview of the skeletogenic process in echinoderms, as well as a discussion of what gene regulatory networks are, and why they [...]
Identify, quantify, act: tackling the unused potential of ecological research
Published: 2021-12-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
‘Ignorance is expensive’. The statement also applies to ignorance of research inefficiencies that can generate huge waste: 85% of health research, amounting to $170 billion annually, is avoidably wasted. This alarming finding elicited a number of responses that have since reduced the waste in health research. Commonality of research and dissemination practices implies that other scientific fields [...]
Source and seasonality of epizootic mycoplasmosis in free-ranging pronghorn (Antilocapra americana)
Published: 2021-12-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Medicine and Health Sciences, Microbiology, Other Ecology and Evolutionary Biology, Pathogenic Microbiology, Veterinary Infectious Diseases, Veterinary Medicine
Mycoplasma bovis is an economically important bacterial pathogen of cattle and bison that most commonly causes pneumonia, polyarthritis and mastitis. M. bovis is prevalent in cattle and commercial bison; however, infections in other species are rare. In early 2019, we identified M. bovis in free-ranging pronghorn (Antilocapra americana) in northeastern Wyoming, USA. Here we report on additional [...]
LONG-TERM MONITORING OF THE EUROPEAN ROLLER (CORACIAS GARRULUS) IN UKRAINE: IS CLIMATE BEHIND THE CHANGES?
Published: 2021-12-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Since the 1980s there has been a long-term decline in numbers and contraction of range in Europe, including Ukraine. Our specific goals were to reconstruct the climatically suitable range of the species in Ukraine before the 1980s, gain better knowledge on its requirements, compare the past and current suitable areas, infer the regional and environmental variables that best explain its [...]
Multiple anthropogenic stressors have inconsistent cumulative effects across a large spatial gradient
Published: 2021-12-09
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Biodiversity is declining, typically because of multiple anthropogenic stressors. Cumulative effects of multiple stressors are classified as additive, when cumulative effects are as expected from the stressor’s singular effects, synergistic when greater than additive or antagonistic when less than additive. Less attention has been given to the consistency of cumulative effects. We analysed stream [...]
