Predicting interaction frequency in plant-pollinator networks
Published: 2025-03-18
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Flowers and their pollinators represent a bipartite interaction system, whose links are hypothesised to be related to species traits. To explore whether we can predict the weight of this link, i.e. the frequency of interactions, in an validation network, we analysed 14 studies of pollinator-flower visitation network from around the world. We used information on species abundances, their traits [...]
Conservation macrogenetics reveals the potential hidden consequences of the 2019-2020 Black Summer fires on Australian biodiversity
Published: 2025-03-18
Subjects: Biodiversity, Genetics, Genomics, Life Sciences, Molecular Genetics, Other Ecology and Evolutionary Biology, Population Biology
The use of genetic analyses has become ubiquitous in conservation planning and management as biodiversity is increasingly threatened globally. Typically, such analyses are employed at the species-level, though as genetic data accrue, it is now possible to consider the genetic composition of multiple species across landscapes. Such macrogenetic perspectives can reveal the potential genetic [...]
The human fingerprint of medicinal plant species diversity
Published: 2025-03-15
Subjects: Anthropology, Biodiversity, Bioinformatics, Biotechnology, Environmental Sciences, Medicine and Health Sciences, Other Languages, Societies, and Cultures
Medicinal plants have long been crucial to human civilizations, supporting both traditional and modern healthcare systems. However, the processes influencing the global diversity and distribution of medicinal plants remain underexplored. Their diversity, like that of other species groups, is shaped by abiotic and biotic influences, which include, in unique ways, human ecological (including [...]
The Interaction Affinity Between Flowers and Their Pollinators
Published: 2025-03-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The probability of flower fertilization by its pollinator is widely recognized as being influenced by species abundances. However, this relationship has rarely been formalized for the analysis of pollination networks. In this study, I introduce a simple model, adapted from physical chemistry, to formalize this functional dependence. This approach draws upon the well-established biochemical [...]
Historical legacies of spatial and temporal climate exposure on thermal physiology shape butterfly vulnerability to recent climate change
Published: 2025-03-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Few observations are more indelible in ecology than widespread variation in the spatial and temporal occurrence of species. Although the mechanistic underpinnings of such variation are likely multifarious, temperature is argued to be a key driver. Understanding how temperature shapes species ranges and seasonal activity not only provides insights into historical biogeographic patterns, but also [...]
The emerging need to manage scavenged wildlife resources
Published: 2025-03-10
Subjects: Biodiversity
Scavenged wildlife products are a unique variety of common pool wildlife resources that are collected without killing or capturing the animal, and their collection is understudied and potentially underregulated relative to their conservation significance. The separability of these products from the animals that produce them complicates efforts to link their harvest to future resource [...]
Monitoring ecological corridors for nature and people
Published: 2025-03-06
Subjects: Biodiversity, Life Sciences
Ecological corridors designed to maintain ecological connectivity between protected and conserved areas is a conservation strategy that is increasingly embraced around the world. Monitoring corridor effectiveness is essential to gauge progress toward connectivity conservation objectives; it also fosters learning among diverse rightsholders and interested parties. In particular, monitoring how [...]
Indirect effects dominate ecosystem service losses in response to agricultural intensification
Published: 2025-03-06
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Feeding a growing human population while preventing biodiversity loss is a major challenge. Land conversion impacts multiple ecosystem services (ESs), including food production and biodiversity-dependent services; yet, the role of indirect effects on ESs within this context, such as parasitoids boosting crop yield by controlling herbivores, remains poorly understood. Using species-network data [...]
Agroecological farming promotes yield and biodiversity but may require subsidy to be profitable
Published: 2025-03-04
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
1. Intensive arable agriculture uses agrochemicals to replace ecosystem services (e.g. pest control and soil health) while simultaneously degrading others (e.g. pollination). Agroecological farming aims to reduce this reliance. Whether these practices maintain yields at a scale relevant to farm business viability is unclear. 2. In a 4-year replicated study across 17 English farms we assessed [...]
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 [...]
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 [...]
Genetic diversity is key to a nature-positive future
Published: 2025-02-21
Subjects: Biodiversity, Genetics and Genomics, Life Sciences
1. Nature-positive describes the concept of halting and then reversing the loss of biodiversity in a manner that is equitable to all, particularly indigenous peoples and local communities. 2. Genetic diversity is the foundational component of biodiversity, underpinning species and ecosystem diversity. Genetic diversity is vital to resilience and ecosystem services. While genetic diversity was [...]
Climate change intensifies plant-pollinator mismatch and increases secondary extinction risk for plants in northern latitudes
Published: 2025-02-19
Subjects: Biodiversity, Ecology and Evolutionary Biology
Climate change is altering the timing of species’ life-cycle events (i.e., phenology), but the rates of phenological shifts vary across taxa. These mismatches in phenological response may disrupt interactions between interdependent species, such as plants and their pollinators, which may lead to reduced plant reproduction via pollen limitation and contribute to secondary extinction risks for [...]
