Extinctions occur when enough individual plants die without replacement to extirpate a population, and all populations are extirpated. While the ultimate drivers of plant extinctions are known, the proximate mechanisms at individual and population level are not. The fossil record supports climate change as the major driver until recently, with land-use change dominating in recent millennia.

- - Changes in land use and climate affect animal populations, with species showing various responses based on their traits; understanding these responses is essential for addressing biodiversity loss.
- - This study analyzed 2,195 populations of birds and mammals across 577 species to investigate the influence of land use, climate changes, and species traits on population changes at global, tropical, and temperate levels.
- - Results indicated that bird populations are more affected by environmental changes than mammals, which are more influenced by longevity; thus, tailored conservation strategies are necessary for birds and mammals in different regions.
Article Synopsis
- - The family Lauraceae consists of six main lineages, but there have been disputes regarding their evolutionary relationships due to differing findings from nuclear ribosomal DNA (nrDNA) and chloroplast (cp) data.
- - The study analyzed the mitochondrial genome of Machilus yunnanensis and reconstructed phylogenetic relationships using 41 mt genes from 92 Lauraceae species, revealing distinct groupings among the lineages, although inconsistencies with nrDNA and cp phylogenies were noted, particularly in certain species.
- - Time-calibrated analyses indicated significant diversification events among these lineages from the Late Cretaceous to the present, with earlier origins for lineages such as Cryptocaryeae and Laureae identified, undersc
Background: Tiny arteriovenous (AV) shunts of 10-150 µm (0.01-0.15 mm) are documented in the hands and feet.
View Article and Find Full Text PDFThe incidence of esophageal adenocarcinoma (EAC) has surged by 600% in recent decades, with a dismal 5-year survival rate of just 15%. Barrett's esophagus (BE), affecting about 2% of the population, raises the risk of EAC by 40-fold. Despite this, the transcriptomic changes during the BE to EAC progression remain unclear.
