The legacy of privilege: Social inheritance reverses sex differences in reproductive inequality in spotted hyenas
Published: 2025-12-02
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Inequalities in reproductive success among females and males shape natural and sexual selec-tion, as well as genetic diversity. A key mechanism influencing reproductive inequality in humans and other animals is the social inheritance of privilege. Using a 29-year dataset spanning eight generations of spotted hyenas (Crocuta crocuta), a species in which social status is maternally inherited, we [...]
An overview of passive acoustic monitoring (PAM) of terrestrial vertebrates and its significance, applications and challenges in urban and natural environments
Published: 2025-11-29
Subjects: Terrestrial and Aquatic Ecology
Amidst a global biodiversity crisis and unprecedented levels of species loss, effective environmental monitoring is more important than ever, but traditional methods are often labour intensive and subjective. Passive acoustic monitoring (PAM) is rapidly establishing itself as an important non-invasive, scalable and cost-effective tool for surveying sonant fauna in both natural and urban [...]
Towards a causal understanding of bidirectional effects in ecology and evolution
Published: 2025-11-28
Subjects: Applied Statistics, Biostatistics, Ecology and Evolutionary Biology, Longitudinal Data Analysis and Time Series
Feedback loops govern many processes in the natural world and are ubiquitous in ecology and evolutionary biology. Despite their prevalence in theory, however, feedbacks and other forms of reciprocal causation are rarely quantified by empiricists working with observational datasets. This divide has been brought to the fore by the causal revolution in the natural sciences. When researchers aim to [...]
Tagged for life? Retention rates and effects on growth and condition of tagging - a long-term field study on PIT- and Carlin tagging in European eel
Published: 2025-11-28
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Different types of tags and markers are commonly used for various fish monitoring and tracking purposes. Effects of tags and markers on fish and the retention rates can affect the interpretation of mark-recapture data on both the individual (e.g. growth and body condition) and population level (e.g. survival and pro-duction estimates), making studies of this issue important. In this study, we [...]
Physiological strategies explain mortality differences amongst ecologically and culturally significant Australian desert plants following a hotter drought
Published: 2025-11-28
Subjects: Plant Biology
Climate change-induced drought and heatwave events (hotter droughts) are causing mass plant dieback events globally. Recently, Uluru-Kata Tjuta National Park (UKTNP) in central Australia saw a widespread plant dieback (mortality) event, resulting in negative impacts to the ecosystems and concern and a desire to understand more about the underlying causes of mass plant death from Anangu [...]
Modelling the current and future potential distribution areas of Columba albitorques in Ethiopia
Published: 2025-11-28
Subjects: Life Sciences
Understanding species’ responses to climate change is essential for predicting future biodiversity patterns and informing conservation strategies. However, in Ethiopia, the impacts of climate change on bird distributions remain poorly documented. This study utilized the MaxEnt model to predict the current and future distribution of the White-collared Pigeon (Columba albitorques) under different [...]
Meeting the Demand: Aligning Marine Biodiversity Data Supply with Policy Needs
Published: 2025-11-28
Subjects: Life Sciences
The effective implementation of international, regional, and national commitments on marine biodiversity depends on reliable data. However, there is often a disconnect between the information generated by scientists and the data explicitly required by policy processes. This review systematically examined more than thirty policy instruments and mapped over 1,000 explicit data requirements to [...]
Adaptive introgression in the context of climate adaptation
Published: 2025-11-27
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics
As the biosphere faces accelerating environmental disruption, including climate change, and the prospect of an anthropogenically-driven mass extinction, understanding the mechanisms that enable species to adapt has become increasingly urgent. One mechanism attracting growing attention is adaptive introgression, the transfer of beneficial genetic variation between closely related species. Although [...]
Resilience and function: Beetles as critical drivers of global ecological processes
Published: 2025-11-27
Subjects: Life Sciences
Beetles (Coleoptera), among the most diverse and ecologically significant insect groups, play vital roles in ecosystem functioning and service provision. With over 300,000 described species, their adaptability - driven by traits such as elytra and diverse feeding habits enables them to occupy nearly all terrestrial niches. Beetles contribute to nutrient cycling, pollination, seed dispersal, pest [...]
From mating to sperm storage: density-dependent plasticity in pre- and post-copulatory shared mating traits
Published: 2025-11-27
Subjects: Life Sciences
Mating interactions depend on traits expressed jointly by males and females, yet the extent to which each sex controls variation in these shared mating traits remains unclear. Because the expression of such traits (like mating latency, copulation duration, and sperm transfer) depends on both partners, their evolution is constrained by intersexual correlations yet facilitated by behavioural [...]
Ecosystem services from shellfish reefs as a nature-based solution: a global evidence synthesis to guide restoration and policy
Published: 2025-11-27
Subjects: Life Sciences
1. Context. Shellfish reefs, comprising oysters, mussels, clams, and mixed bivalves, act as ecosystem engineers and nature-based solutions (NbS), providing supporting, regulating, provisioning, and cultural ecosystem services (ES). Yet, despite rapid growth in restoration practice, the translation of ES evidence into policy and management remains uneven across regions and taxa. 2. Objectives. We [...]
Quantifying Energy-Efficient Evolution in Cursorial Avian Archosaurs Through Comparative Torque-Based Hindlimb Modeling
Published: 2025-11-27
Subjects: Evolution, Paleobiology
Understanding the way evolution drives adaptations that “optimize” energy-efficiency in cursorial species provides instrumental insights into both biomechanical and bio-inspired engineering fields. This study quantitatively models the cursorial evolution of energy-efficient locomotion in bird-line archosaurs by comparing the hindlimb mechanics of Deinonychus antirrhopus (extinct theropod) and [...]
Quantifying impacts of policy and practice interventions on biodiversity and climate
Published: 2025-11-27
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
There is urgent demand for ecosystem management interventions – targeted actions through policies and practices – that meaningfully address climate change and biodiversity loss while sustaining ecosystem delivery of water, food, fibre and fuel. Rigorous quantification of intervention outcomes is required for decision makers to identify, promote and scale effective interventions. Yet [...]
Forest fecundity declines as climate shifts
Published: 2025-11-27
Subjects: Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Tree fecundity underpins regeneration, range tracking, and seed supply for assisted migration, yet may decline as climates move beyond reproductive niches. Using 34 years of nationwide harvest records from Poland (40,530 observations across 438 forest districts) for five dominant taxa — oaks (Quercus robur, Q. petraea), European beech (Fagus sylvatica), Scots pine (Pinus sylvestris), and silver [...]

Published: 2025-11-27
Subjects: Life Sciences
Salinity stress threatens rice (Oryza sativa L.) production across 1.056 million hectares of Bangladesh's coastal regions, with intensification projected due to climate change and sea-level rise. Marker-assisted breeding (MAB) has emerged as a transformative approach for developing salt-tolerant varieties, offering precision and efficiency over conventional methods. This review examines [...]
