Há 4 dias · Ocelot temporal activity patterns differed between the protected area and the mixed-use area, with increased nocturnality in areas of higher human impact. Our SECR results highlight that matrix habitats can support ocelot populations, emphasizing the need for further research on ocelot demographics in human-modified Amazon rainforest areas facing varying degrees of anthropogenic disturbance.
Há 5 dias · CO 2 addition experiments, both in glasshouse and field settings, provide critical insights into both the quantum-yield and WUE mechanisms of CO 2 fertilization in C 3 and C 4 plants, and experiments do broadly confirm that both C 3 and C 4 plants can and do experience CO 2 fertilization in a wide variety of contexts (Polley et al., 1997, 2019; Wand et al., 1999; Pan et al., 2022).
Há 3 dias · The conservation and restoration of forest ecosystems require detailed knowledge of the native plant compositions. Here, we map global forest tree composition and assess the impacts of historical ...
Há 2 dias · The investigation of taxonomic diversity within island plant communities stands as a central focus in the field of island biogeography. Phylogenetic diversity is crucial for unraveling the evolutionary history, ecological functions, and species combinations within island plant communities. Island effects (area and isolation effect) may shape species distribution patterns, habitat heterogeneity ...
Há 1 dia · Acrolein (ACR), methylglyoxal (MGO), and glyoxal (GO) are a class of reactive carbonyl species (RCS), which play a crucial role in the pathogenesis of chronic and age-related diseases. Here, we explored a new RCS inhibitor (theanine, THE) and investigated its capture capacity on RCS in vivo by human experiments. After proving that theanine could efficiently capture ACR instead of MGO/GO by ...
Há 2 dias · Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Há 4 dias · Our aims were (1) to characterize the distribution of J. sibirica and the main tree species at the treeline on these peaks, (2) to estimate tree cover, snow depth, soil temperature, and wind speed at key sites that varied in percentage of J. sibirica cover, (3) to assess temporal changes in the species composition, morphometric and areal characteristics of J. sibirica and trees on a constant ...
