Globally, urban expansion has led to habitat fragmentation and altered resource availability, thus posing significant challenges for wildlife. The Chinese pangolin () is a critically endangered species experiencing population decline due to illegal trade and habitat degradation. This study analyzed variables affecting habitat occupancy of Chinese pangolins using a single-season occupancy model across 134 study grids (600 m × 600 m) in peri-urban areas of Dharan Sub-Metropolitan City, eastern Nepal.

  • Human activity and climate change are major contributors to the decline and potential extinction of the Reeves's pheasant, leading to its designation as a nationally protected species in China.
  • A study utilized habitat suitability models and various environmental data to predict the bird's habitat changes from 1995 to 2050, revealing significant habitat loss due to land use and climate change, with projections showing a potential loss of 89.58% of its habitat.
  • To mitigate these threats, it is recommended to enhance cooperation among government entities, restore degraded habitats, and establish ecological corridors to support the bird's population.

Biological invasions pose significant threats to ecological and economic stability, with invasive pests like the Asian longhorned beetle ( Motschulsky, ALB) causing substantial damage to forest ecosystems. Effective pest management relies on comprehensive knowledge of the insect's biology and invasion history. This study uses genomics to address these knowledge gaps and inform existing biosurveillance frameworks.

Pine stem rust, the most damaging and widespread forest disease occurring in pine trees in the Northern Hemisphere, is primarily caused by species (Pucciniales, Melampsorineae). While the phylogenetic relationships of major species have been largely elucidated, there is limited understanding of their species diversity and the evolutionary processes shaping their distribution patterns. In this work, we performed broad sampling and sequencing of taxa in China together with additional sequence data and other accessions in NCBI to investigate the diversification and to estimate the divergence time of major evolutionary events in this genus.

The decline in biodiversity poses a serious threat to natural ecosystems and has become one of the most pressing global environmental issues. Establishing conservation priorities for protected areas (PAs) is one of the most direct and effective biodiversity conservation measures. However, conservation gaps arise as a result of existing problems in spatial layout of PAs, including overlapping protection scopes, artificial fragmentation of natural ecological regions, as well as "over-protection" and "over-exploitation.

Type 1 diabetes mellitus (T1DM) is an autoimmune disease that can lead to severe diabetic complications. While the changes and correlations between gut microbiota and the pathogenesis of T1DM have been extensively studied, little is known about the benefits of interventions on gut bacterial communities, particularly using probiotics, for this disease. In the present study, we reported that the mice surviving after 5 months of streptozotocin (STZ) injection had reduced blood glucose level and recovered gut microbiota with increased proportion.

The invasion of alien woody species may have broad ecological, economic, and health impacts on ecosystems and biodiversity under climate change. Previous studies showed that disrupting the biodiversity conservation mechanisms in protected areas can seriously threaten natural ecosystems and the protection of rare and endangered species in such protected areas. However, there is currently no standard for evaluating the invasion risk of woody plants under climate change when establishing national parks in China.

Background: (Scopoli, 1763), the type species of the Osmylidae, has garnered significant research interest in taxonomy, particularly regarding its larval stages. To date, most studies have focused on the third instar larvae, but ignore the first instar larvae with the rough and incomplete morphological descriptions. This lack of studies has led to an unclear understanding of the morphological differences between larval stages, making it challenging to identify larvae, distinguish different osmylid species or even reconstruct phylogeny.

The unprecedented habitat fragmentation or loss has threatened the existence of many species. Therefore, it is essential to understand whether and how these species can pace with the environmental changes. Recent advantages in landscape genomics enabled us to identify molecular signatures of adaptation and predict how populations will respond to changing environments, providing new insights into the conservation of species.

Article Synopsis
  • The freshwater fish genus being studied consists of 75 known species, making it the largest group of cavefish, exhibiting specific adaptations for living in cave environments, such as eye degeneration and skin depigmentation.
  • The research focuses on a peculiar behavior called wall-following (WF), which is thought to be more pronounced in eyeless species of cavefish compared to their normal- or micro-eyed counterparts.
  • Findings reveal that eyeless cavefish show significantly stronger wall-following behavior, indicating this trait is likely an ancestral behavior enhanced by adaptations for life in dark, subterranean habitats.

The geographical variation and domestication of tree species are an important part of the theory of forest introduction, and the tracing of the germplasm is the theoretical basis for the establishment of high-quality plantations. Chinese pine ( Carr) is an important native timber tree species widely distributed in northern China, but it is unclear exactly where germplasm of the main Chinese pine plantation populations originated. Here, using two mtDNA markers, we analyzed 796 individuals representing 35 populations (matR marker), and 873 individuals representing 38 populations (nad5-1 marker) of the major natural and artificial populations in northern China, respectively (Shanxi, Hebei and Liaoning provinces).
