Pollination across the diel cycle: a global meta-analysis

Liam Kendall, Charlie C Nicholson

Published: 2024-03-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Yet, despite over six decades of research into whether plant reproductive success varies between day and night, consensus remains elusive. We compiled and analysed the [...]

Patterns in tern trophic diversity in a region experiencing rapid climate change

Natasha Jeanne Gownaris, Linda Welch, Jill Tengeres

Published: 2024-03-29
Subjects: Life Sciences

Foraging plasticity provides a mechanism for long-lived species to adapt to rapidly changing environments and, when individuals vary in their plasticity, can drive changes in trophic diversity. We use chick provisioning data and stable isotope values of blood cells and plasma to test for drivers of trophic diversity in the diet of common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea) [...]

Restrictions on UK aquaculture of Pacific oyster (Magallana gigas) will not prevent naturalised spread but suppress ecological and economic benefits to coastal communities

Alexander W Shakspeare, Tom C Cameron, Michael Steinke

Published: 2024-03-29
Subjects: Life Sciences

The Pacific oyster (Magallana (Crassostrea) gigas) was introduced to UK waters in the mid 20th century and currently accounts for over 95% of UK oyster fishery landings. Recently however, its non native origin has led policy makers to consider a limit on UK oyster aquaculture operations. M. gigas is effectively naturalised in the UK, with multiple records of populations originating from non local [...]

Blood lead increases and haemoglobin decreases in urban birds along a soil contamination gradient in a mining city

  Lead contaminated soil is a persistent global threat to the health of animal populations. Nevertheless, links between soil lead and its adverse effects on exposed wildlife remain poorly understood. Here, we explore local geographic patterns of exposure in urban birds along a gradient of lead contamination in Broken Hill, an Australian mining city. Soil lead concentrations are linked to [...]

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 as structural parasites of the tree-host. Both contrasting ideas on the role of lianas in forest ecosystems challenge the practitioners and decision might be taken without specific information. Here we present a preliminary result, applied in a unique, small, old-growth forest in the [...]

Behavioral variation changes across an urbanization gradient in a population of great tits

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 in adaptive traits, we still have very 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 [...]

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. The genome-wide coverage and greater marker density provided by WGS data, compared to popular reduced-representation sequencing approaches, 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

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 [...]

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 [...]

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 [...]
