Knowing why Tasmanian Eucalyptus obliqua tall forests are so sensitive to heatwaves informs management and policy for climate change adaptation

Tim Wardlaw

Published: 2024-03-29
Subjects: Life Sciences

Tasmania’s distinctive climate environment supports highly productive and carbon-dense tall eucalypt forests, but also a vulnerability to climate change. Measurements in Eucalyptus obliqua tall forest at the Warra SuperSite in southern Tasmania showed them to be very sensitive to warmer temperatures. Gross primary productivity (GPP) declines sharply when temperatures rise above the forest’s [...]

Zebra finch song parameters are affected by the breeding status of the male, but not temperature variability

Maëlle Lefeuvre, Joanna Rutkowska

Published: 2024-03-16
Subjects: Life Sciences

Bird song is a crucial feature for mate choice and reproduction. Song can potentially communicate information related to the quality of the mate, through song complexity, structure or finer changes in syllable characteristics. It has been shown in zebra finches that those characteristics can be affected by various factors including motivation, hormone levels or extreme temperature. However, [...]

Potter Cove’s Heavyweights: Estimation of species’ interaction strength of an Antarctic food web

Iara Diamela Rodriguez, Leonardo A Saravia

Published: 2024-03-16
Subjects: Life Sciences

Understanding the complex interplay between structure and stability of marine food webs is crucial for assessing ecosystem resilience, particularly in the context of ongoing environmental changes. In the West Antarctic Peninsula, global warming has led to severe alterations in community composition, species distribution, and abundance over the last decades. In this study, we estimate the [...]

Lianas, to cut or not to cut to conserve forest biodiversity?

Ricardo A. Moreno, Gabriel Ortega-Solis, Javier Godoy, et al.

Published: 2024-03-16
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences

Although lianas play an important role in forest composition, structure, and functions, they are considered structural parasites of trees. Both contrasting ideas on the role of lianas in forests challenge practitioners during restoration activities and management decisions might be taken without specific information. Here we evaluated the effects of lianas on their host-trees in a small [...]

Behavioral DiverCity: Individual differences in behavior change along an urbanization gradient

Laura Gervais, Megan Thompson, Pierre de Villemereuil, et al.

Published: 2024-03-15
Subjects: Life Sciences

Urbanization is occurring globally at an unprecedented rate and, despite the eco-evolutionary importance of individual variation, we still have limited insight on how phenotypic variation is modified by anthropogenic environmental change. Urbanization can increase individual differences in some contexts, but whether this is generalizable to behavioral traits, which directly affect how organisms [...]

Variant calling in polyploids for population and quantitative genetics

Alyssa Phillips

Published: 2024-03-15
Subjects: Life Sciences

Advancements in genome assembly and sequencing technology have made whole genome sequence (WGS) data and reference genomes accessible to study polyploid species. Compared to popular reduced-representation sequencing approaches, the genome-wide coverage and greater marker density provided by WGS data can greatly improve our understanding of polyploid species and polyploid biology. However, [...]

Social interactions do not affect mycoplasma infection in griffon vultures

Elvira D'Bastiani, Nili Anglister, Inna Lysnyansky, et al.

Published: 2024-03-14
Subjects: Life Sciences

Uncovering the ways in which pathogens spread has important implications for population health and management. Pathogen transmission is influenced by various factors, including patterns of social interactions and shared use of space. We aim to understand how the social behavior of griffon vultures (Gyps fulvus), a species of conservation interest, influences the presence or absence of mycoplasma, [...]

Not All Mass Mortality Events are Equal

Samantha Jean Sawyer, Micky D. Eubanks, Jeffery K. Tomberlin

Subjects: Ecology and Evolutionary Biology, Entomology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Microbiology, Population Biology

Mass Mortality Events (MMEs) are defined as novel events involving many individuals dying in a relatively short period of time. In recent years, there has been an increased interest in MMEs due to their perceived increase in frequency. Current definitions are subjective and categorize mortalities varying in magnitude and frequency together. Within this manuscript, Multiple Mortality Events is a [...]

Urban greenspaces benefit both human utility and biodiversity

Nataly G. Miguez, Brittany M. Mason, Jiangxiao Qiu, et al.

Published: 2024-03-13
Subjects: Life Sciences, Social and Behavioral Sciences

Urban greenspaces are essential for both human well-being and biodiversity, with their importance continually growing in the face of increasing urbanization. The dual role of these spaces raises questions about how their planning and management can best serve the diverse needs of both people and biodiversity. Our goal was to quantify the synergies and tradeoffs between human utility and [...]

Satellite images reveal major discrepancies between mapped and operating wind turbines in a hotspot of wind energy development

Jacopo Cerri, Chiara Costantino, Davide De Rosa, et al.

Published: 2024-03-12
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

Wind energy is an emerging challenge for biodiversity conservation, due to its impacts on habitats and species. Therefore, effective mitigation and zonation policies require accurate maps of operating wind turbines. However, the current pace of wind energy development raises doubts on how fast existing maps can become obsolete. We used freely available satellite imagery from Google to check the [...]

Temperature drives the evolutionary diversification of male harm in Drosophila melanogaster flies

Claudia Londoño-Nieto, Michael Butler, Roberto García-Roa, et al.

Published: 2024-03-12
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution

Sexual selection often leads to sexual conflict via pre-copulatory (harassment) and/or copulatory (traumatic insemination) male harm to females, impacting population growth, adaptation and evolutionary rescue. Male harm mechanisms are diverse and taxonomically widespread, but we largely ignore what ecological factors modulate their diversification.  Here, we conducted experimental evolution under [...]

Community-wide masting improves predator satiation in North American oaks

Jakub Szymkowiak, Michał Bogdziewicz, Shealyn Marino, et al.

Published: 2024-03-12
Subjects: Ecology and Evolutionary Biology, Life Sciences

Mast seeding, a phenomenon observed in numerous perennial plant species, is highly variable reproduction across years, synchronized among individuals within a population. One major fitness advantage of masting lies in the reduction of seed predation rates, achieved through alternating phases of seed scarcity and abundance that starve and subsequently satiate seed consumers. Proximately, the [...]

The fecundity costs of building complex nests in birds

Claire Jayne Taylor, Iliana Medina, Mark C Mainwaring

Published: 2024-03-07
Subjects: Life Sciences

Animal nests provide a beneficial environment for offspring development and as such contribute to fitness. Gathering and transporting materials to construct nests is energetically costly, but the life history trade-offs associated with the complexity of nests built are largely unknown. Who contributes to building the nest could also mediate these trade-offs, as building a nest as a couple is [...]

Habitat fragmentation and loss is a known threat to biodiversity. Their combined effect leaves organisms in small isolated patches of habitat, contributing to the current biodiversity crisis. The first response of animals to environmental change is typically behavioral. Beyond the physical elements of the environment, the "social landscape" shapes the spatial distribution of the habitats [...]
