Carbon dioxide (CO) supersaturation in lakes and rivers worldwide is commonly attributed to terrestrial-aquatic transfers of organic and inorganic carbon (C) and subsequent, in situ aerobic respiration. Methane (CH) production and oxidation also contribute CO to freshwaters, yet this remains largely unquantified. Flood pulse lakes and rivers in the tropics are hypothesized to receive large inputs of dissolved CO and CH from floodplains characterized by hypoxia and reducing conditions.

Tropical freshwater ecosystems are some of the world's most biodiverse and productive systems where determining what sustainable exploitation of inland fisheries looks like is particularly challenging. One of the greatest obstacles to sustainable management is collecting and using quality data on fish production and yield. The biodiversity and hydro-ecology of these systems often under open-access governance, add to the complexity of managing them.

Article Synopsis
  • Understanding the genetic makeup of populations across management borders is crucial for conserving biodiversity and food resources, especially in fragmented habitats.
  • The study of the catfish species Hemibagrus spilopterus in the Mekong River basin identified two distinct genetic lineages, suggesting potential cryptic species, and indicated limited long-distance migration among them.
  • Findings revealed that fish populations in tributaries had significantly lower genetic diversity and higher inbreeding levels, making them more susceptible to threats such as human-induced habitat fragmentation from dams.
