Evolutionary perspectives on thiamine supplementation of managed Pacific salmonid populations
Published: 2024-02-10
Subjects: Life Sciences
Thiamine deficiency complex (TDC) in fishes has been identified in an ever-expanding list of species and populations. In many documented occurrences of TDC in fishes, rates of juvenile mortality have reached 90% at the population level, with many females producing no surviving offspring. Such sweeping demographic losses and concomitant decreases in genetic diversity due to TDC can be prevented by [...]
Survival patterns and population stability of cliff plants suggest high resistance to environmental variability
Published: 2024-02-10
Subjects: Biodiversity, Ecology and Evolutionary Biology
Cliffs are marginal and poorly studied habitats that are home to a high proportion of endemic or threatened species. Here, we review the survival patterns and population dynamics of plants growing on vertical cliffs and compare them to other plants with similar life histories that grow on the ground. To this end, we have compiled studies of cliff and ground plants from two main sources: MONITO [...]
The costs and benefits of publicising species discoveries.
Published: 2024-02-10
Subjects: Applied Mathematics, Biodiversity, Biology
Public information about where species are found can influence what happens to them – from building support to protect their habitat, to telling poachers where to find a target. Recent heated scientific debate about whether to release information about species’ locations when new species or populations are found have highlighted the trade-off between the risk of damage or loss versus the benefits [...]
Leveraging Biodiversity Net Gain to address invertebrate declines in England
Published: 2024-02-10
Subjects: Biodiversity, Entomology
Meeting ambitions such as the Global Biodiversity Framework 2030 targets will require multiple conservation mechanisms that benefit the widest possible range of habitats and species. Here, we evaluate the likely impact of a novel and ambitious ecological compensation policy, Biodiversity Net Gain (BNG) in England, on terrestrial insects, spiders, and other arthropods (‘invertebrates’), a [...]
Ten Simple Rules to build a Model Life Cycle
Published: 2024-02-09
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Software Engineering
Just like data, models have their own life cycle. By recognizing how one’s model fits within the life cycle of the data (or at least, ensuring that the model life cycle is understood), we can identify opportunities to foster new collaborations, encourage better practices in data analysis, and ultimately accelerate research. In this manuscript, we introduce the Model Life Cycle and develop a [...]
Global exposure risk of frogs to increasing environmental dryness
Published: 2024-02-08
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Zoology
Compared with the risks associated with climate warming and extremes, the risks of climate-induced drying to animal species remain understudied. This is particularly true for water-sensitive groups, such as anurans (frogs and toads), whose long-term survival must be considered in the context of both environmental changes and species sensitivity. Here, we mapped global areas where anurans will [...]
The impact of acoustic signalling on offspring performance varies between three biparentally caring species
Published: 2024-02-08
Subjects: Social and Behavioral Sciences
Communication plays a fundamental role in the evolution of any form of cooperative behaviour such as parental care. However, it can be challenging to understand the specific role of certain signals and how they might have evolved into complex communication systems. To investigate what effect a lack of acoustic communication can have on brood care and offspring performance, we silenced parents of [...]
Large-scale spatio-temporal variation in vital rates and population dynamics of an alpine bird
Published: 2024-02-01
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Population Biology, Statistical Models
Quantifying temporal and spatial variation in animal population size and demography is a central theme in ecological research and important for directing management and policy. However, this requires field sampling at large spatial extents and over long periods of time, which is not only prohibitively costly but often politically untenable. Participatory monitoring programs (also called citizen [...]
Sexual system variation in legumes (Leguminosae): underpinning genomic study with new tools to describe inflorescence morphology
Published: 2024-02-01
Subjects: Biology, Botany, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Sciences
Although the great majority of legume species are cosexual with hermaphrodite flowers, a variety of sexual systems are observed in the family, including monoecy, andromonoecy, androdioecy and dioecy. Such broad terms conceal much variation, details that may be of importance in understanding the evolutionary and ecological basis of reproductive systems. This variation is often inadequately [...]
Selection versus Transmission: Quantitative and Organismic Biology in Antibiotic Resistance
Published: 2024-02-01
Subjects: Life Sciences, Medicine and Health Sciences
We aimed to determine the importance of selection (mostly dependent on the anthropogenic use of antimicrobials) and transmission (mostly dependent on hygiene and sanitation) as drivers of the spread of antibiotic-resistant bacterial populations. The first obstacle to estimating the relative weight of both independent variables is the lack of detailed quantitative data concerning the number of [...]
What is the evidence that counter-wildlife crime interventions are effective for conserving African, Asian, and Latin American wildlife directly threatened by exploitation? A Systematic Map
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology
1. Counter-wildlife crime interventions ̶ those that directly protect target wildlife from illegal harvest/persecution, detect and sanction rule-breakers, and interdict and control illegal wildlife commodities ̶ are widely applied to address biodiversity loss. This systematic map provides an overview of the literature on the effectiveness of counter-wildlife crime interventions for conserving [...]
How bottlenecks shape adaptive potential: from theory and microbiology to conservation biology
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Wild populations frequently undergo demographic changes that can destabilize their persistence and, thus, the equilibrium of ecosystems. For instance, habitat loss due to human activities leads to a drastic population size reduction, a process called a bottleneck. By reducing genetic diversity, a bottleneck may prevent a population from adapting to subsequent environmental changes. In the context [...]
Adult telomere length is positively correlated with survival and lifetime reproductive success in a wild passerine
Published: 2024-02-01
Subjects: Evolution
Explaining variation in individual fitness is a key goal in evolutionary biology. Recently, telomeres, repeating DNA sequences capping the ends of chromosomes, have gained attention as a biomarker for body state, individual quality, and ageing. However, existing research has provided mixed evidence for whether telomere length correlates with fitness components, including survival and reproductive [...]
The relative contribution of acoustic signals versus movement cues in group coordination and collective decision-making
Published: 2024-01-30
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
To benefit from group living, individuals need to maintain cohesion and coordinate their activities. Effective communication thus becomes critical, facilitating rapid coordination of behaviours and reducing consensus costs when group members have differing needs and information. In many bird and mammal species, collective decisions rely on acoustic signals in some contexts but on movement cues in [...]
Satellite Observations Reveal a Positive Relationship Between Trait-Based Diversity and Drought Response in Temperate Forests
Published: 2024-01-30
Subjects: Life Sciences
Climate extremes such as droughts are expected to increase in frequency and intensity with global change. Therefore, it is important to map and predict ecosystem responses to such extreme events to maintain ecosystem functions and services. Alongside abiotic factors, biotic factors such as the proportion of needle and broadleaf trees were found to affect forest drought responses, corroborating [...]
