Short-term responses of ground-dwelling arthropod communities to habitat loss and fragmentation in experimental mesoscale landscapes

Scientific Reports
Habitat loss and fragmentation are main drivers of biodiversity decline. However, disentangling their respective effects remains tricky and contrasting results have emerged in previous studies leading to a call for finely designed landscape-scale ...

Noninvasive Characterization of Tumor Heterogeneity in HNSCC: From Clinical Utility to Biological Correlates

Advanced Science, EarlyView.
This study establishes a CT‐based radiomics framework to quantify intratumoral heterogeneity (ITH) in HNSCC. Using unsupervised clustering, tumor ROIs and VOIs are analyzed to calculate 2D/3D ITH scores. The score shows strong predictive value for prognosis and immunotherapy response, and is associated with tumor metabolism and immune microenvironment,

The effect of habitat fragmentation on Malay tapir abundances in Thailand’s protected areas

Global Ecology and Conservation
Habitat loss and fragmentation in tropical regions are major threats to the persistence of endangered Malay tapir (Tapirus indicus). The Malay tapir distribution is largely constrained to fragmented habitats inside protected areas. However, it is unclear

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Complex Measures of Habitat Fragmentation and Edge Can Complicate Biodiversity Conservation

Conservation Letters
Understanding habitat fragmentation effects on wildlife is critical to promoting effective conservation practices. There are many metrics of habitat fragmentation, from simple (number of habitat patches) to complex metrics designed to summarize many ...

The use of fynbos fragments by birds: Stepping-stone habitats and resource refugia

Koedoe: African Protected Area Conservation and Science, 2016
Fynbos habitats are threatened by fragmentation through land use and anthropogenic changes in fire regimes, leading to a loss of suitable habitat for birds.

Optimal resource allocation to survival and reproduction in parasitic wasps foraging in fragmented habitats. [PDF]

PLoS ONE, 2012
Expansion and intensification of human land use represents the major cause of habitat fragmentation. Such fragmentation can have dramatic consequences on species richness and trophic interactions within food webs.

Microalgae Hybrid Biosystem for Enhanced Oral Delivery of Rifaximin in Hepatic Encephalopathy Treatment

Advanced Science, EarlyView.
The microalgae‐nanoparticle hybrid system with antibacterial activity can improve the oral delivery and therapeutic efficiency for hepatic encephalopathy treatment. Oral administration of the system can reduced systemic ammonia levels, enhanced intestinal barrier function, attenuated systemic and neuroinflammation, ameliorated cognitive impairments ...

Positive effects of fragmentation per se on the most iconic metapopulation

Conservation Letters
While habitat loss is a major threat to species, the effects of habitat fragmentation independent of habitat loss (fragmentation per se) are debated.

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

Advanced Science, EarlyView.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes
