Modeling future tree species distributions under climate change to guide restoration planning: Application to the Brazilian Amazon
Published: 2025-03-01
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Other Forestry and Forest Sciences
Addressing climate change and biodiversity loss requires innovative approaches to ecosystem restoration. This study aims to (1) develop a statistical tool to predict species distribution shifts under future climate scenarios and (2) apply it to 30 key tree species in the Brazilian Amazon, a biodiversity hotspot increasingly threatened by deforestation and climate change. Using MaxEnt, we modeled [...]
theRmalUAV: an R package to clean and correct thermal UAV data for accurate land surface temperatures
Published: 2025-03-01
Subjects: Agricultural Science, Climate, Environmental Monitoring, Software Engineering
Thermal cameras mounted on unoccupied aerial vehicles (UAVs) are increasingly utilized across various environmental research fields, including hydrological modelling, wildfire detection, urban heat island studies, microclimate and precision agriculture. However, several steps are needed to convert the measured thermal signal to more relevant land surface temperature (LST). Since a number of users [...]
A Practical Decision Tool for Marine Bird Mortality Assessments
Published: 2025-03-01
Subjects: Life Sciences
Given the rise in anthropogenic, environmental, and disease events contributing to marine bird mortality, there is a critical need to improve the rigor of mortality assessments. Deficits in data collection and mortality estimation can hinder a manager’s ability to document event scales and inform population level impacts. Therefore, to inform decisions required during activities such as [...]
Climate-linked evolution and genetics in a warming Arctic
Published: 2025-02-28
Subjects: Biology, Life Sciences
The extent to which species might be able to evolutionarily respond to rapid environmental change relies strongly on their genetic diversity. Accurate knowledge of both patterns of evolution and genetic variation across the species range is important for determining appropriate conservation and management strategies. The Arctic is the fastest-warming region on the planet, with the rest of the [...]
Ecosystem services of insectivorous bats in intensively managed arable land benefit from adjacent near-natural areas
Published: 2025-02-28
Subjects: Life Sciences
Ecosystem services provided by insectivorous bats are an important yet underappreciated economic benefit of biodiversity. To investigate what is needed to maintain these services, we asked whether bat-mediated ecosystem services depend on near-natural areas adjacent to farmland. We used high-throughput tracking and genetic sequencing to determine the habitat use and diet of 128 common noctule [...]
Heterogeneous individuals impede the establishment of cultures in animal groups
Published: 2025-02-27
Subjects: Ecology and Evolutionary Biology
Social learning facilitates the diffusion of novel behaviours (i.e., inventions) through groups and is a key component in the development of culture. The speed with which an invention spreads through a group is largely determined by the strength of social connections and network structure; however, research concerning the establishment of inventions (i.e., culture) has typically overlooked that [...]
The hidden figures at species boundaries: the mitochondrial energetics behind mating signal divergence
Published: 2025-02-27
Subjects: Life Sciences
The energy expenditure of mating signals is often divergent between species and mediates heterospecific mating, thus influencing the direction of gene flow across the species boundaries. The relative energetics of the mating signals can be underpinned by mitochondrial haplotypic divergence between species, which contributes to hybrid mitonuclear incompatibility and speciation. Here, we discuss [...]
Transferable approaches to CRISPR-Cas9 induced genome editing in non-model insects: a brief guide
Published: 2025-02-27
Subjects: Animal Experimentation and Research, Animal Sciences, Entomology, Genetics, Life Sciences, Molecular Genetics, Other Genetics and Genomics, Zoology
Despite the large variety of insect species with divergent morphological, developmental and physiological features questions on gene function could for a long time only be addressed in few model species. The adoption of the bacterial CRISPR-Cas system for genome editing in eukaryotic cells widened the scope of the field of functional genetics: for the first time the creation of heritable genetic [...]
Rapid declines in southern Sierra Nevada fisher habitat driven by drought and wildfire
Published: 2025-02-27
Subjects: Forest Management, Life Sciences, Population Biology
Forest disturbances are a natural ecological process, but climate and land-use change are altering disturbance regimes at an unprecedented rate, posing significant threats to biological communities and species of concern. Our aim was to develop an automated habitat monitoring system for the Southern Sierra Nevada Distinct Population Segment of fisher (Pekania pennanti) in California, USA to [...]
No refuge at the edge for European beech as climate warming disproportionately reduces masting at colder margins
Published: 2025-02-27
Subjects: Ecology and Evolutionary Biology, Forest Sciences, Physical and Environmental Geography
Reproduction is vital for forest resilience to climate change, as tree populations depend on adequate seed production to recover demographically from disturbances and migrate to more suitable sites. Neglecting reproduction in projections of habitat suitability and range shifts risks overestimating forest resilience to climate change. For many tree species, including European beech (Fagus [...]
Ecology in Africa: historical perspectives, present state and prospects
Published: 2025-02-26
Subjects: Life Sciences
Ecology research, education and conservation policies in Africa are heavily influenced by western science and philosophy, resulting in the marginalization of African traditional ecological knowledge (TEK) systems. This legacy persists in post-colonial African government structures and academic institutions, influencing teaching methodologies, research approaches, and conservation policy [...]
There is no such thing as an herbivore: incidental and intentional ingestion profoundly affects both herbivores and plant-dwelling invertebrates.
Published: 2025-02-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Real-life ‘herbivores’ are not the herbivores of our simplistic ecological and behavioral models – real-life herbivores constantly consume other organisms both incidentally and intentionally, with the ‘prey’ usually consisting of plant-dwelling arthropods, smaller invertebrates, and carrion. A remarkable amount of disparate literature has amassed on these phenomena, yet the implications of these [...]
Tracing the history of angiosperm systematics through Liliales and Asparagales
Published: 2025-02-26
Subjects: Life Sciences
The field of systematics is central to how we understand, classify, and discuss organisms and their evolution. Systematics directly or indirectly touches every branch of biology. Over the last 50 years, methods in the field have been continually reshaped by advancing technologies, transitioning from primarily relying on morphological data to utilizing genomic-scale data sets. As the methods [...]
Combining eDNA and Museomics to Enhance Biodiversity Monitoring
Published: 2025-02-26
Subjects: Biodiversity, Life Sciences, Other Ecology and Evolutionary Biology, Other Genetics and Genomics
Biodiversity changes due to human activities highlight the need for efficient biodiversity monitoring approaches. Environmental DNA (eDNA) metabarcoding offers a non-invasive method to assess species distributions, but its accuracy depends on comprehensive DNA reference databases. Natural history museum collections often contain rare or difficult to obtain samples that could be used as a resource [...]
Landscape anthropization drives composition and diversity of butterfly communities at a regional scale
Published: 2025-02-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Aim While landscape anthropization is a key driver of biodiversity change, its effects on communities are underexplored, especially at regional scales. In the Anthropocene, climate and habitat diversity alone are insufficient to explain community structure. However, until recently, ecologists lacked accessible, synthesized data describing anthropization gradients, which limited studies to [...]
