Behavioural ecology at the spatial-social interface

Quinn Webber, Gregory Albery, Damien R. Farine, et al.

Published: 2022-02-11
Subjects: Biology, Integrative Biology, Life Sciences

Spatial and social behaviour are fundamental aspects of an animal’s biology, and the social and spatial environments are indelibly linked through mutual causes and shared consequences. Behavioural variation at the “spatial-social interface”, which we define as the intersection of social and spatial aspects of individuals’ phenotypes and environments, has implications for ecological and [...]

1. Budgeting for biodiversity conservation requires realistic estimates of the costs of threat abatement. However, data on the costs of managing threats to biodiversity is often unavailable or unable to be extrapolated across relevant locations and scales due to a lack of transparency and consistency in how it was collated. Conservation expenditure largely occurs without a priori estimates costs [...]

Recent genomic evidence suggest that kea (Nestor notabilis) have a non-functional RH2 opsin gene potentially leading to impaired vision in the green region of the electromagnetic spectrum. In New Zealand, it is standard procedure to add green dye to aerial poison baits used in mammalian predator control operations to deter native birds from eating toxic bait. A visual deficiency could impact how [...]

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 [...]

Plant community data from a statewide survey of paired serpentine and non-serpentine soils in California, USA

Jesse E. D. Miller, Stella Copeland, Kendi Davies, et al.

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

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 [...]

Behavioral flexibility is manipulable and it improves flexibility and innovativeness in a new context

Corina J Logan, Dieter Lukas, Aaron Blaisdell, et al.

Published: 2022-01-05
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 [...]

Ecogeography of group size suggests differences in drivers of sociality among cooperatively breeding fairywrens

Allison E. Johnson, Joseph F. Welklin, Ian R. Hoppe, et al.

Published: 2022-01-05
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences

Cooperatively breeding species exhibit a range of social behaviors associated with different costs and benefits to group-living, often in association with different environmental conditions. For example, species in which collective-care of offspring reduces the cost of reproduction are more common in harsh environments (true cooperative breeding), while species that collectively defend resources [...]

State of the Amphibia 2020: A review of five years of amphibian research and existing resources

Molly C. Womack, Emma Cathleen Steigerwald, David Blackburn, et al.

Published: 2021-12-16
Subjects: Biology, Life Sciences

Amphibians are a clade of over 8,400 species that provide unique research opportunities and challenges. With amphibians undergoing severe global declines, we posit that assessing our current understanding of amphibians is imperative. Focusing on the past five years (2016–2020), we examine trends in amphibian research, data, and systematics. New species of amphibians continue to be described at a [...]

Identifying cryptic fern gametophytes using DNA barcoding: A review

Joel Nitta, Sally M. Chambers

Published: 2021-12-14
Subjects: Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Sciences

Ferns and lycophytes are unique among land plants for having sporophyte (diploid) and gametophyte (haploid) generations that can grow independently of each other. While most studies of fern ecology focus on the more obvious sporophytic stage, the gametophyte is critically important, as it is the sexual phase of the life cycle. Yet, fern gametophytes have long been neglected in field studies due [...]

Bothersome burrowers: tracking gopher (Thomomys bottae) time-averaging in a late-Holocene site in California

Maria Viteri, Elizabeth Hadly

Published: 2021-12-04
Subjects: Biology, Integrative Biology, Life Sciences

Understanding the taphonomic biases affecting fossil deposits is necessary in order to extract their true ecological signals. In terrestrial sites, the mixing of fossil material by mammalian bioturbators can substantially increase time-averaging, obscuring or even erasing stratification. In particular, pocket gophers (Thomomys sp.) are known to burrow in Holocene sites and thereby complicate the [...]

Mitochondria as the powerhouses of sexual selection: testing mechanistic links between development, cellular respiration, and bird song

Ondi L. Crino, Steph Falk, Andrew Katsis, et al.

Published: 2021-12-04
Subjects: Biology, Integrative Biology, Life Sciences

Although the influence of developmental conditions on the expression of sexually selected traits is established, the physiological mechanisms that modulate such effects remain a matter of intense debate. Here, we test the role of the developmental environment in shaping adult mitochondrial function and link mitochondrial function to expression of a sexually selected trait in males (bird song). We [...]

Early diversifications of angiosperms and their insect pollinators: Were they unlinked?

Yasmin Asar, Simon Y. W. Ho, Hervé Sauquet

Published: 2021-11-19
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

The present-day ubiquity of angiosperm-insect pollination has led to the hypothesis that these two groups coevolved early in their evolutionary history. However, recent fossil discoveries and fossil-calibrated molecular dating analyses challenge the notion that early diversifications of angiosperms and insects were inextricably linked. In this article we examine (i) the discrepancies between [...]

The role of sexual isolation during rapid ecological divergence: evidence for a new dimension of isolation in Rhagoletis pomonella

Alycia Lackey, Alyssa Murray, Nadia Mirza, et al.

Published: 2021-11-16
Subjects: Biology, Integrative Biology, Life Sciences

The pace of divergence and likelihood of complete speciation may depend how and when different types of reproductive barriers evolve. After initial reproductive barriers evolve, questions remain about how subsequently evolving barriers may facilitate additional divergence and potential speciation. We tested for the presence of sexual isolation (reduced mating between populations due to divergent [...]
