Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

River Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Phenology and phenological variability of Mexican ecosystems

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Time senes of vegetation index data provide useful information of vegetation activity. These curves can be used for retrieving key phenological stages such as the day of season onset, peak, and end. These parameters allow for better understanding the landscape and, if conducted for several years, its natural variability or human-induced change.

Breeding phenology and climate⃛

Nature, 1998
European amphibians and birds have been breeding consistently earlier over the past two to three decades1,2. These changes have been attributed to the observed trends in increasing average spring temperatures in Europe3 producing earlier growing seasons4 and increased forage availability.
