Freshwater ecosystems contribute substantially to the global fish catch. However, freshwater fisheries face growing human pressures and are underrepresented in global analyses and conservation strategies. Attempts to reconcile conservation and human welfare goals in fisheries have led to comanagement by the government and local communities, along with other stakeholders, but assessments of its effectiveness in freshwater fishe...

Inland fisheries underpin food security in many tropical countries. The most productive inland fisheries in tropical and subtropical developing countries occur in large river–floodplain systems that are often impacted by land cover changes. However, few studies to date have assessed the effects of changes in floodplain land cover on fishery yields. Here, we integrated fisheries and satellite‐mapped habitat data to evaluate the...

In the present study a unique dataset on population abundance in various community‐based management ( CBM ) and non‐ CBM areas is analysed to address the question of whether CBM can recover overexploited populations of Arapaima sp. in river‐floodplain ecosystems. All non‐ CBM areas possessed depleted Arapaima sp. populations with a mean density of 0·01 individuals ha −1 . Arapaima sp. population densities in all CBM areas chan...

Most nests of Arapaima gigas in floodplains of the Amazon were built at the margins of the forests surrounding temporary or permanent lakes and their connecting channels. They were found under forested levees in locations that were shallow and sandy. From 2000 to 2005, the adult population increased six‐fold but nest density increased only two‐fold.

Winter precipitation increases as much as seven times from south to north along the US Pacific coast. For 1948–95, nine coastal grid points are used to identify spatial and temporal winter precipitation variations and to assess atmospheric circulation influences on precipitation variability. A strong negative correlation to the northwest of each precipitation grid point is revealed by one‐point correlation maps of precipitatio...
