Different sources of wind turbine data produce sharp differences in collision risk estimates for foraging vultures
Published: 2024-12-06
Subjects: Biodiversity, Environmental Monitoring, Systems Biology, Zoology
Multiple studies assessed the collision risk of different vulture species with wind turbines. However, they relied on different sources of wind turbine data, and the effect of this data heterogeneity, on the estimated collision risk and the comparability of these assessments, has not been investigated. We used GPS and accelerometer data, collected from 6 adult Griffon Vultures living in Sardinia [...]
Unbaited underwater video evidences the presence of previ-ously unrecorded fish species, sea krait (Laticauda sp.) and a high frequency of sharks at a remote reef complex (Coral Sea Marine Park, Southwest Pacific)
Published: 2024-12-06
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
The Chesterfield-Bellona atolls and reefs are a vast reef complex located in the Coral Sea Marine Park, estab-lished in 2014 in the New Caledonian Economic Exclusive Zone. In 2013, the New Caledonia government supported the first assessment of fish and benthic habitats conducted in all habitats and over the entire area. The assessment provided a primary knowledge base for establishing the [...]
Advancing Plant Biomass Measurements: Integrating Smartphone-based 3D Scanning Techniques for Enhanced Ecosystem Monitoring
Published: 2024-12-06
Subjects: Life Sciences
New technological developments open novel possibilities for widely applicable methods of ecosystem analyses. We investigated a novel approach using smartphone-based 3D scanning for non-destructive, high-resolution monitoring of above-ground plant biomass. This method leverages Structure from Motion (SfM) techniques with widely accessible smartphone apps and subsequent computing to generate [...]
Experimental tests on the evolution of sex and recombination and their adaptive significance
Published: 2024-12-06
Subjects: Life Sciences
Sex and recombination generate genetic variation and facilitate adaptation by reducing selective interference, but they can also disrupt genotype combinations maintained by selection. We here synthesize recent experimental evolution studies on the adaptive consequences of sex and recombination in constant environments, emphasizing insights gained from population genomic data. We discuss evidence [...]
One Earth + One Health: An agile, evolutionary, system-of-systems, convergence paradigm for societal challenges of the Anthropocene
Published: 2024-12-06
Subjects: Education, Engineering, Life Sciences, Medicine and Health Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Evolutionary mechanisms enabled humans to profoundly transform Earth systems. Because the resulting Anthropocene systems are highly interdependent and dynamically evolving, often with accelerating rates of cultural and technological evolution, the ensuing family of societal challenges must be framed and addressed in a holistic fashion. An agile, evolutionary, system-of-systems, convergence [...]
Self-organising life history selection from replicating molecules to large multicellular sexual organisms
Published: 2024-12-02
Subjects: Life Sciences
During their evolution from molecular replicators over asexual unicellular prokaryotes and protozoa to multicellular sexual reproducers, biological lifeforms increased in size with heritable gene replication increasingly embedded in more organised replicating units. Natural selection theory did not explain this evolutionary unfolding for 150 years, consolidating Darwinian evolution as a [...]
Evolutionary principles shape the health of humanity as a planetary-scale organism
Published: 2024-12-02
Subjects: Life Sciences, Social and Behavioral Sciences
A study of human social systems at planetary scale examines whether our technology, economy, culture, and flows of information are component-processes in a unified, living system. Through a biological lens of structure, function, and geographic mapping of social systems, we consider this total human ecosystem from evolutionary and developmental principles. The health of this system depends on its [...]
Temperature-related developmental plasticity, not selection, affects offspring body size and shape in a bird of prey
Published: 2024-11-29
Subjects: Ecology and Evolutionary Biology
Recent climate warming has led to a reduction in bird body size and a relative elongation of their appendages, consistent with Bergmann’s and Allen’s ecogeographical rules. These changes are generally interpreted as thermoregulatory adaptations for more efficient passive heat dissipation; however, direct evidence supporting this assumption is currently missing, and laboratory studies failed to [...]
Home of the brave: is similarity of defensive behavior of Neotropical snakes (Dipsadidae: Pseudoboini) predicted by sympatry?
Published: 2024-11-29
Subjects: Life Sciences
Predation is a strong driver of prey behavior and sympatric species are exposed to similar selective predatory pressures.We test the hypothesis that this leads to similar anti-predator behaviors using the widespread Neotropical snake tribe Pseudoboini. We reviewed and compiled documented defensive behaviors for all species, adding new unreported behaviors for three species. We used a cluster [...]
Stronger together? A framework for studying population resilience to climate change impacts via social shielding
Published: 2024-11-28
Subjects: Life Sciences
1. Climate change is driving a rapid increase in the frequency and intensity of extreme climatic events, leading to substantial alterations in climate patterns and other environmental conditions. These changes are often degrading habitats and increasing thermal, water, and nutritional stress for animals, thereby elevating general stress levels and imposing energetic costs. 2. Social behaviours [...]
Enhancing Canopy Research in Africa: Insights from Tree Climbing Workshop in Ghana
Published: 2024-11-28
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology
The report shares the background and experience executing a tree climbing workshop in Ghana. In most cases, canopy research in Africa is conducted under the umbrella of parachute science, leaving local scientists deprived of canopy access skills and equipment. Consequently, tropical Africa experiences a closed canopy so far as canopy ecology is concerned. In May 2024, ten (10) early career [...]
IUCN Red List of Ecosystems, Mangroves of the Galapagos
Published: 2024-11-28
Subjects: Ecology and Evolutionary Biology, Life Sciences
Mangroves of the Galapagos is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of Eastern Galapagos Islands, Northern Galapagos Islands, and Western Galapagos Islands. The Galapagos province mapped extent in 2014 was 36.6 km2, representing 0.03% of the global mangrove area. The biota is characterized by four species of true [...]
Overcoming the disconnect between interaction networks and biodiversity conservation and management
Published: 2024-11-27
Subjects: Biodiversity, Ecology and Evolutionary Biology
Decision-makers need to act now to halt biodiversity loss, and ecologists must provide them with relevant species interaction indicators to inform on community- and ecosystem-level changes. Yet, the integration of ecological networks into conservation is still virtually nonexistent. Here, we discuss challenges and opportunities related to uncertainty, interpretability and relevance of network [...]
Individual foraging specialization and success change with experience in a virtual predator-prey system
Published: 2024-11-27
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology
The capacity of predators to match their tactic to their prey and to optimize their skills at implementing a given tactic are expected to drive the outcome of predator-prey interactions. Hence, successive interactions of predators with their prey may result in increased flexibility in tactic use or in individual foraging specialization. Yet, there are limited empirical assessments showing links [...]
Stability in the Face of Global Decline: A 20-Year Study of Arthropods in an Oceanic Archipelago
Published: 2024-11-27
Subjects: Life Sciences
Insect declines have been reported globally but whilst island ecosystems are potentially facing exacerbated challenges, no long-term studies (LTER) have confirmed this trend. This study utilises the first available LTER data on island invertebrates, targeting epigeal and canopy arthropods from the Azores, and covering over 20 years in three distinct sampling events from 30 standard sites. We [...]
