Article Synopsis
- Habitat anthropization negatively impacts global biodiversity, but some species show adaptive life-history responses, like increased reproduction, to cope with these changes.
- The study focused on the yellow-bellied toad and utilized a large dataset of over 21,000 individuals from various European populations to examine the effects of anthropogenic environments on their survival and reproduction.
- Results indicated that while adult toads had lower survival and shorter lifespans in human-modified habitats, their increased reproductive output compensated for these losses, helping to maintain stable population growth rates despite habitat alterations.
Article Synopsis
- Triturus cristatus and Triturus marmoratus, two protected newt species in Vienne, France, face declining populations due to their limited ability to disperse and the impact of climate change on habitat suitability and connectivity.
- The study used ecological niche modeling to assess how climate scenarios (RCP 2.6 and RCP 8.5) may alter habitat conditions, revealing that warmer temperatures could significantly reduce suitable habitats, particularly for T. cristatus.
- Findings suggest that the loss of habitat connectivity due to decreased suitability could threaten these species, providing critical insights for conservation strategies and land management policies aimed at protecting newt habitats.
