Insect monitoring without pitfalls: seven steps for robust insect sensing systems
Published: 2026-02-13
Subjects: Artificial Intelligence and Robotics, Biodiversity, Computer Sciences, Ecology and Evolutionary Biology, Entomology, Life Sciences
Data shortages fuel controversy about an ongoing insect biodiversity crisis. Insects are immensely diverse and functionally critical for ecosystems, yet data on insect trends remain patchy and biased. Sensors, ranging from camera-equipped light traps to weather radar stations, are set to transform entomological data collection. Meanwhile, AI models that extract biological information from sensors [...]
Assessing how far a ‘Net Zero’ strategy moves an organisation towards ‘Nature Positive’ contributions
Published: 2026-02-13
Subjects: Biodiversity
‘Net Zero’ and ‘Nature Positive’ frameworks can guide organisations to contribute towards climate and biodiversity goals, but are often implemented separately. It remains unclear whether achieving Net Zero strategies can aid progress towards Nature Positive goals. We apply footprinting methods to a case study (Wadham College, Oxford) to quantitatively assess whether an organisational Net Zero [...]
A systematic map and comprehensive database of animal organ sizes
Published: 2026-02-12
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Pharmacology, Toxicology and Environmental Health
The relationship between individual organ size and overall body size in animals is a fundamental biological phenomenon that spans multiple disciplines. However, a comprehensive synthesis of the sources of variation in organ-specific scaling remains lacking, even among mammals, the most extensively studied vertebrate group. We developed a systematic map and compiled a large database of paired [...]
The incredible vulnerability that reproduction poses for plant species in a warming world
Published: 2026-02-12
Subjects: Life Sciences
Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival. While crop scientists have found that key reproductive stages are particularly vulnerable to heat stress across plant systems, ecological and [...]
Oxygen limitation is not a major physiological mechanism restricting early life development in zebrafish
Published: 2026-02-12
Subjects: Life Sciences
Early life stages are considered particularly vulnerable to warming because tissue oxygen supply is thought to become limiting, given their underdeveloped gill function and reliance on passive oxygen diffusion. Here, we tested whether oxygen availability constrains early development under warming in zebrafish (Danio rerio). We exposed embryos and early-stage larvae to a high-resolution factorial [...]

Interplay of diet, heat stress, and the microbiome shapes health and escape behavior in amphibian larvae
Published: 2026-02-11
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Microbiology, Organismal Biological Physiology
What animals eat modulates their microbiome and is fundamental to their health. Microbiomes can improve hosts’ ability to cope with environmental stressors, including increased temperatures and altered food quantity and quality associated with climate change. Using a multifactorial experimental design, we tested whether three diets with increasing amounts of protein, fat, and components of animal [...]
Towards an integrated understanding of animal weapons
Published: 2026-02-11
Subjects: Life Sciences
Animals resolve conflict using an astonishing array of weapons – from electric fields and sonic shockwaves to deadly venom and high-impact strikes. Most weapon research has typically considered only a single weapon modality at a time with a focus separately on weapons under sexual selection or natural selection. Further, few studies have examined how weapons are integrated into the larger [...]
Have human impacts exceeded climate in shaping mammalian distributions?
Published: 2026-02-10
Subjects: Ecology and Evolutionary Biology
Human impacts are increasingly recognized as drivers of biogeographic patterns, yet it remains unclear whether they surpass climate in shaping species distributions. Here we aim to investigate the relative importance of anthropogenic vs. climatic factors in determining mammalian distributions. We modeled the relationship between the geographic distributions of 331 mammal species and 12 [...]
Should hunters fear the wolf? Effects of wolf recolonization on ungulate harvests in a multi-species European landscape
Published: 2026-02-10
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Population Biology, Zoology
1. The recolonization of European landscapes by the gray wolf Canis lupus raises questions about the ecological effects of predators and their impact on human interests such as large-game hunting bags, leaving room for alarmism among hunters. 2. We investigated the impact of wolf on recreational hunting by using long-term (2006-2023) and high-resolution (234 hunting districts) hunting bag data on [...]
Ecological facilitation hinders adaptation to climate change in a stressful environment
Published: 2026-02-10
Subjects: Life Sciences
Many plants, in (semi-)arid ecosystems in particular, rely on so-called nurse plants for protection and growth, in a species interaction called ecological facilitation. However, it is not clear whether facilitation will protect the facilitated plant from extinction if the environmental conditions change, for example due to climate change. Here, we use an evolutionary model to study the impact of [...]
Generating a national snapshot of all publicly-reported investments in ecosystem and species conservation across public, private, and philanthropic finance
Published: 2026-02-10
Subjects: Environmental Studies, Nature and Society Relations
Scaling up investment in ecosystems is a national and international public policy priority, but evaluations of the total amount spent have been severely criticised for a lack of methodological rigour. Increasingly governments are looking to the private sector to fill the nature finance ‘funding gap’, but a lack of transparent reporting of especially private finance flows is a known limitation. In [...]
Modeling evolutionary rescue
Published: 2026-02-09
Subjects: Ecology and Evolutionary Biology, Life Sciences
A population that avoids extinction by adapting to environmental change is said to be rescued by evolution. Evolutionary rescue is of fundamental interest in ecology and evolution and of great relevance in conservation, where rescue of endangered species is wanted, and in medicine and agriculture, where rescue (resistance evolution) of pathogens, cancers, and pests is unwanted. Theory plays a key [...]
Life cycle complexity drives variation in thermal tolerance and plasticity
Published: 2026-02-09
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences, Terrestrial and Aquatic Ecology, Zoology
Accumulating evidence suggests that heat tolerance varies substantially across insect development, yet patterns of variation remain difficult to generalise across species. We discuss how the diversity of insect developmental strategies shapes both the intensity and predictability of thermal environments across ontogeny, and how this likely generates variation in heat tolerance, plasticity, and [...]
The potential for passive acoustic monitoring and automated detection to improve conservation efforts of tarsiers in Sulawesi, Indonesia
Published: 2026-02-09
Subjects: Life Sciences
Tarsiers are small, haplorrhine primates that occur in Southeast Asia. Tarsiers on the island of Sulawesi range from Vulnerable to Critically Endangered, and many are data deficient, which means there is a great need for improved monitoring approaches. Sulawesi tarsiers are pair-living, territorial, and engage in duets within human hearing range, which makes them ideal candidates for passive [...]
