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: 2025-02-25
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 [...]
Comunicación breve sobre germinación de 15 especies nativas chilenas, de áreas protegidas desérticas costeras, semi desértica, mediterránea y templada
Published: 2025-02-24
Subjects: Life Sciences
Las comunidades vegetales están cambiando su diversidad y composición debido al cambio climático y las presiones humanas (IPCC 2023), lo que a menudo conduce a condiciones irreversibles. En Chile, muchas plantas nativas están enfrentando dificultades ya que su rango de distribución se está desplazando o reduciendo (Anderson, 2016), aumentando la necesidad de restaurar las comunidades vegetales [...]
Investigating the Effects of Future Climate on Arbuscular Mycorrhizal Fungal Spore Dynamics in a Belgian Pear Orchard Ecosystem
Published: 2025-02-24
Subjects: Life Sciences
Climate change affects soil microbial communities, including arbuscular mycorrhizal fungi (AMF), crucial for plant nutrient uptake and resistance to pathogens. This study examines the impact of future climate on the abundance, functional group composition and temporal dynamics of AMF spores in Belgian pear orchards using an advanced Ecotron climate simulation facility. By simulating present [...]
Belowground communities in lowlands are less stable to heat extremes across seasons
Published: 2025-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Ecological responses to climate extremes vary drastically in different spatiotemporal contexts. Here, we investigate how soil communities at high- and low-elevation sites respond to extreme heat events in different seasons (spring, summer and autumn). We simulated 1-week heat events based on site-specific climatic history in laboratory experiments using 360 field-collected soil cores and measured [...]
Motif-weighted Structure Alignment for Classification and Evolutionary Studies of Carbonic Anhydrase
Published: 2025-02-24
Subjects: Bioinformatics, Life Sciences
Carbonic anhydrases (CAs) attract interest for their critical roles in various physiological processes and potential application in CO2 sequestration to combat global warming. Despite being an important enzyme family, the classification and evolution of CAs remain elusive due to their high sequence diversity and long evolutionary history. In this paper, the in-silico strategy, Motif-weighted [...]
Quantifying changes in fish population stability using statistical early warnings of regime shifts
Published: 2025-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Ecological conservation and management benefits from tools that can foresee impending problems, or those in early stages. Statistical early warnings of regime shifts, which can identify generic changes in system behavior associated with stability loss and potential abrupt changes to a new, distinct state, are theoretically well grounded and have been successfully applied in real-world settings.
