A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished —doubling in numbers and growing larger. This unprecedented look into prehistoric reef communities shows how the loss of top predators cascaded through the entire food web, shifting the balance amongst coral reefs
Scientists at the University of Southampton have developed a new way of analysing fossils allowing them to see how creatures from millions of years ago were shaped by their environment on a day-to-day basis for the first time.
A recently published article in the journal BioScience reveals that endangered longleaf pine ecosystems—among North America's most biodiverse habitats—face mounting threats from intensifying hurricane regimes driven by climate change. An interdisciplinary team of authors headed by Nicole Zampieri (Tall Timbers and The Jones Center at Ichauway) describe the urgent situation: The North American Coastal Plain was once characterized by extensive longleaf pine savannas covering approximately 36 million hectares. Today, these ecosystems "now occupy less than 5% of their historic distribution, primarily because of habitat fragmentation, widespread unsustainable logging, land-use conversion, and fire suppression during the past half millennium."
Virginia Tech researchers have discovered a clever new way to detect an invasive pest — by letting ants lead the way.
