A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, EarlyView.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

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.

Macroalgal Composition Determines the Structure of Benthic Assemblages Colonizing Fragmented Habitats. [PDF]

PLoS ONE, 2015
Understanding the consequences of fragmentation of coastal habitats is an important topic of discussion in marine ecology. Research on the effects of fragmentation has revealed complex and context-dependent biotic responses, which prevent generalizations

Artificial Intelligence in Autonomous Mobile Robot Navigation: From Classical Approaches to Intelligent Adaptation

Advanced Intelligent Systems, EarlyView.
Artificial intelligence (AI) is reshaping autonomous mobile robot navigation beyond classical pipelines. This review analyzes how AI techniques are integrated into core navigation tasks, including path planning and control, localization and mapping, perception, and context‐aware decision‐making. Learning‐based, probabilistic, and soft‐computing methods

Responses of steppe birds to habitat fragmentation: Insights from niche specialization and functional traits

Avian Research
Habitat fragmentation poses a significant threat to bird communities, especially those in open and semi-open ecosystems such as steppes. This study investigates how steppe birds adapt to and utilize fragmented habitats by combining niche modeling with ...

An Estimation of Urban Fragmentation of Natural Habitats: Case Studies of the 24 Italian National Parks

Chemical Engineering Transactions, 2013
Italy is a densely populated country, where most of the land is actively used by its human population. As a result, many of the remaining natural areas are subject to different typologies of human pressures that generally cause habitat fragmentation ...

Transition from connected to fragmented vegetation across an environmental gradient: scaling laws in ecotone geometry [PDF]

, 2009
A change in the environmental conditions across space—for example, altitude or latitude—can cause significant changes in the density of a vegetation type and, consequently, in spatial connectivity.
