Researchers have compiled a comprehensive updated checklist of terrestrial mammals on Hainan Island, China's largest tropical island. The study documents 95 species, including 12.91% of China's terrestrial mammalian species richness, and identifies 10 species as threatened under IUCN criteria.
Researchers found that tree-layer α-diversity peaks at mid-elevation zones, while understory α-diversity shows a bimodal trend with two diversity peaks at 400-600m and 1000-1200m. Community composition differs among low-, mid- and high-elevation zones, driven by species turnover across elevational zones.
Researchers used eDNA metabarcoding to study fish biodiversity in heavily damaged mountainous cascade dammed rivers. The study found 97 fish species, including 14 IUCN threatened taxa, with seasonal differences in species detection rates and community composition.
A recent study published in Biological Diversity reveals that ecological selection drives population differentiation and local adaptation in Capsella bursa-pastoris, a widely distributed annual herb. Genome-wide scans identified 54 candidate genes under positive selection related to energy metabolism and other processes.
The study highlights a core trade-off between spatial resolution, spectral bandwidth and plot-pixel matching in arid ecosystems. Multi-source, multi-scale remote sensing fusion is advocated for future dryland biodiversity conservation and management.
A new study reveals critical fine-scale spatial heterogeneity of mesozooplankton across three brackish bays of the Central and Eastern Baltic Sea. Salinity and temperature drive distinct zooplankton assemblages, with clear inter-bay community separation emerging.
Researchers unveil a rigorous framework to fix global forest carbon credit systems, addressing methodological defects and promoting biodiversity conservation. The new standards aim to produce high-integrity climate assets while safeguarding community interests.
The TSESOM framework proposes a dynamic service ecosystem approach to manage sustainable operations in botanic gardens, integrating biodiversity research and ecosystemic thinking. It offers a flexible tool for transformative collaboration and innovation, supporting planetary health and global sustainability transitions.
Researchers found that plant species with tougher leaves actually suffered more from insect damage, while those with higher silicon concentrations sustained less. In contrast, plants with higher heat tolerance experienced greater herbivory. Understanding these drivers is crucial for predicting forest health under future climate scenarios.
A long-term study found that invasive Burmese pythons led to a dramatic decline in woodrat populations, while cotton mouse populations surged following Hurricane Irma's landfall. The study highlights the disproportionate impact of invasive predators on endemic ecosystem engineers and underscores the need for targeted conservation efforts.
A new commentary reveals that most of Africa's biodiversity persists outside formal protected areas, challenging the reliance on fenced reserves and policies like the 30×30 target. Working landscapes, shaped by centuries of human-nature coexistence, often retain higher ecological connectivity and resilience to climate change.
A research team found that tropical forest plants increase root carbon exudation to stimulate phosphatase activity, mineralize organic P, and release organic acids to dissolve mineral-bound P. This adaptation helps alleviate P limitation under long-term N enrichment, sustaining productivity.
A research team found that tropical forest plants increase root carbon exudation to stimulate phosphatase activity and release organic acids to dissolve mineral-bound P. The organic acid pathway drove twice as much P release as the phosphatase pathway.
The study found a clear hump-shaped elevational pattern with species richness peaking at approximately 600 m, supporting the mid-domain effect. Community structure was differentiated by body size and biomass, with lizards contributing most of the individuals but only 66% of total biomass.
A research team has identified two distinct genetic lineages corresponding to low- and high-altitude habitats in Capsella bursa-pastoris. Genome-wide scans detected 54 candidate genes under positive selection, highlighting temperature seasonality and precipitation as key drivers of adaptive divergence.
A study on the phylogeography of Burmannia nepalensis, a rare mycoheterotrophic herb in subtropical China, found that historical climate fluctuations and geographic isolation shaped its evolutionary history. The research reveals limited gene flow due to mountain barriers and fragmented habitats.
A novel study in Biological Diversity reveals the integrated physiological and symbiotic adaptation mechanism underlying P. purpuratum's ex situ conservation. The research demonstrates that ex situ conservation elevates seed-set rates but incurs trade-offs in photosynthetic capacity and oxidative stress.
The Hefei Botanical Garden is a key institution for biodiversity research in East China, with over 5000 plant species preserved, including rare and endangered species. The garden promotes sustainable resource utilization, ecological education, and rural revitalization through its 'Botanical Garden + Agriculture' model.
A comprehensive study using integrated genomic approach resolves Hylodesmum's taxonomic uncertainties and EA-ENA disjunct distribution. The study confirms Verdesmum as nested within Hylodesmum and reveals a complex bidirectional dispersal pattern likely facilitated by mammal-mediated epizoochory.
