Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors: Upstream, Reservoir, Reduced Flow Sector, and Downstream. We aimed to quantify spatial a...

The southern brown shrimp (Penaeus subtilis) is the primary crustacean species commercially exploited by the industrial trawl shrimp fleet operating over the Amazon continental shelf. However, there is no information on the economic viability of this activity. Economic studies on fisheries can provide guidance in the design and implementation of management measures. This study estimated the cost and profitability of industrial...

Ecological seasonality describes the dynamic adaptation of species to changes in the biotic community and suggests predators should alter space use synchronously with seasonal prey availability. We assessed seasonal space use states (i.e., periods of similar movement and resource use) of mainland gray wolves ( Canis lupus ), moose ( Alces alces ), and white-tailed deer ( Odocoileus virginianus ) on the Grand Portage Indian Res...

Landslide runout and debris-flow inundation can disrupt areas well beyond their initial sources, causing widespread damage and extensive fatalities. Understanding where they start and how far they might travel is essential in many locations worldwide. However, most landslide susceptibility maps focus on initiation areas and fail to incorporate runout areas. Furthermore, hazards vary greatly with the degree of landslide mobilit...
