Mosses Play Key Roles in Ecosystems from Tropics to Tundra
A global survey of mosses growing on soil found that the somewhat underappreciated plants cover a vast area and perform tasks such as sequestering carbon.
مراقبة تراكم الملوثات من المعادن الثقيلة في دلتا النيل
تُظهر نتائج تحاليل العينات أن إعادة استخدام مياه الصرف بدون معالجة والتوسع في إنشاء السدود يسبب زيادة تركيز المعادن الثقيلة الملوثة في دلتا النيل مما يهدد بشدة سلامة النظام البيئي والصحي والإنتاج الزراعي في مصر.
Suivie de l’accumulation des métaux lourds dans le Delta du Nil
Les analyses de sédiments montrent que la réutilisation de l’eau non traitée et la construction de barrages entraînent l’augmentation des concentrations de métaux lourds dans le Delta du Nil, menaçant gravement les écosystèmes, l’agriculture et la santé humaine.
Tracking Heavy Metal Accumulation in the Nile Delta
Sediment measurements show that flow alterations and discharges are driving increasing concentrations of multiple heavy metals in the Nile Delta, threatening ecosystems, agriculture, and human health.
Why Tropical Forests Are Important for Our Well-Being
Tropical forests play a critical role in supporting human well-being, food security, and the maintenance of biodiversity.
Glacial Ice Offers Polar Bears a Precarious Climate Refuge
An isolated polar bear population in southeastern Greenland survives in fjords, despite spotty sea ice. But this pocket of bears is not a sign of how the species could be saved.
Warmer Winters Keep Crops Sleepy into Spring, Hurting Yield
Annual crops go dormant during winter. Frosty temperatures cue them to wake up—but the warmer winters brought on by climate change scramble the cold signal, hurting yield.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
Plant-Nibbling Insects May Make It Cloudier and Cooler
Insects that eat plant leaves could change the local atmosphere, but current climate models do not account for this impact.
