Subjects: Biodiversity, Communication, Ecology and Evolutionary Biology, Environmental Studies, Library and Information Science, Life Sciences, Publishing, Scholarly Publishing, Social and Behavioral Sciences
Consulting the best available evidence is key to successful conservation decision-making. While much scientific evidence on conservation continues to be published in non-English languages, a poor understanding of how non-English languages science contributes to conservation decision-making is causing global assessments and studies to practically ignore non-English-language literature. By [...]
Microclimate shifts in nest-boxes and natural cavities before, during and after nesting
Published: 2022-01-17
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Physiology, Population Biology
Animals breeding in anthropogenic shelters such as nest-boxes experience nesting environment in which they did not originally evolve. Over the past decades, they are additionally challenged by climate change – a major environmental force influencing their reproductive ecology. Despite the central importance of nesting microclimate for offspring development and fitness, very little is known about [...]
Adaptations and plastic phenotypic responses of marine animals to the environmental challenges of the high intertidal zone
Published: 2022-01-16
Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Physiology
The high intertidal zone is home to an incredible variety of marine animals, as it offers an escape from low intertidal/subtidal predation and competition, among other advantages. However, this area of the shore also comes with many tide-driven and emersion-associated environmental stressors, such as desiccation, high temperatures and freezing stress, hypoxia, salinity fluctuations, nitrogenous [...]
A SPECIES DISTRIBUTION MODEL OF THE ANTARCTIC MINKE WHALE (BALAENOPTERA BONAERENSIS)
Published: 2022-01-15
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
The Antarctic minke whale (Balaenoptera bonaerensis) is regarded a Southern Hemisphere endemic found throughout the Southern Hemisphere, generally south of 60°S in austral summer. Here they have been routinely observed in highest densities adjacent to and inside the sea ice edge, and where they feed predominantly on krill. Detecting abundance trends regarding this species by employing visual [...]
Flower strips increase the control of rosy apple aphids after parasitoid releases in an apple orchard
Published: 2022-01-15
Subjects: Agricultural Economics, Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Horticulture, Life Sciences, Plant Sciences
Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides to control the rosy apple aphid Dysaphis plantaginea in organic apple orchards. As a proof of concept study, we tested if the presence of flower strips between apple tree rows could improve the action of three early parasitoid releases—and of other naturally [...]
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 [...]
Latitudinal but not elevational variation in blood glucose level is linked to life history across passerine birds

Subjects: Animal Sciences, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences, Physiology, Zoology
Macrophysiological research is vital to our understanding of mechanisms underpinning global life history variation and adaptation under diverse environments. Birds represent an important model taxon in this regard, yet our knowledge is limited to only a few physiological traits, mostly studied in temperate and Neotropical species. Here, we examined latitudinal and elevational variation in an [...]
Molecular Paleobiology of the Echinoderm Skeleton

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 [...]
Form, Function, Agency: Sources of Natural Purpose in Animal Evolution
Published: 2022-01-08
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
The origination and evolution of multicellular form and function is generally thought to be based on gene-based variation, with natural selection changing the populational composition in the respective variants over time. The criterion for evolutionary success is differential fitness, the relative capacity to leave progeny in the next generation. Theoretical considerations show that this model [...]
Mussels repair shell damage despite limitations imposed by ocean acidification
Published: 2022-01-08
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Terrestrial and Aquatic Ecology
Bivalves frequently withstand shell boring attempts by predatory gastropods that result in shell damage that must be quickly repaired to ensure survival. While the processes that underlie larval shell development have been extensively studied within the context of ocean acidification (OA), it remains unclear whether shell repair is impaired by elevated pCO2. To better understand the stereotypical [...]

Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
In the era of globalization, biological invasions are one of the most serious social issues. Thus, managing its impact is an urgent task. It is essential to control non-native species before they become established. However, it is insufficient to address establishment debt, which occurs when a non-native species has been introduced into an area but has not yet been established in the wild. In [...]
Behavioral flexibility is manipulable and it improves flexibility and innovativeness in a new context
Published: 2022-01-06
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Behavioral flexibility, the ability to adapt behavior to new circumstances, is thought to play an important role in a species' ability to successfully adapt to new environments and expand its geographic range. However, flexibility is rarely directly tested in a way that would allow us to determine how flexibility works to predict a species' ability to adapt their behavior to new environments. We [...]
