Freshwater crabs from the highlands of the Venezuelan Guayana

, 2022
Neotropical freshwater crabs have a wide distribution range from southern Mexico to Peru, including the entire Amazon basin and the Guianas. Among them, highland species of the genus Microthelphusa Pretzmann, 1968, have a very peculiar biogeography. Their distribution is insular and discontinuous, presenting considerable separation between them. Twelve

Different processes lead to similar patterns: a test of codivergence and the role of sea level and climate changes in shaping a southern temperate freshwater assemblage

BMC Evolutionary Biology, 2011
Background Understanding how freshwater assemblages have been formed and maintained is a fundamental goal in evolutionary and ecological disciplines. Here we use a historical approach to test the hypothesis of codivergence in three clades of the Chilean ...

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Trait compensation in marine gastropods: shell shape, avoidance behavior, and susceptibility to predation [PDF]

, 2004
Many organisms have evolved morphological and behavioral traits that reduce their susceptibility to predation. However, few studies have explicitly investigated the relationships between defensive traits and susceptibility. Here we demonstrate a negative

Dietary N‐Acetylserotonin offers protection against Shewanella putrefaciens infection in Chinese mitten crab Eriocheir sinensis

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Shewanella putrefaciens is an important bacterial pathogen that poses a serious threat to Chinese mitten crab (Eriocheir sinensis) aquaculture. However, the protective effects of N‐Acetylserotonin (NAS) against S. putrefaciens infection in E. sinensis remain unknown.
