Biological nitrogen fixation (BNF) supports terrestrial primary productivity and plays key roles in mediating human-induced changes in global nitrogen (N) and carbon cycling. However, there are still critical uncertainties in our understanding of the amount of BNF occurring across terrestrial ecosystems, and of how terrestrial BNF will respond to global change. We synthesized BNF data from Latin America, a region reported to sustain some of the highest BNF rates on Earth, but that is underrepresented in previous data syntheses.

- Mangroves have lower species diversity than other tropical forests but are structurally and functionally diverse.
- The study examined nitrogen dynamics in two types of mangroves (fringe and basin) in southeastern Brazil, hypothesizing that fringe forests would show greater nitrogen cycling due to tidal influences.
- Results indicated that fringe forests had higher nitrogen mineralization rates and availability, while nitrification rates were similar to those in basin forests.
Goniopsis cruentata is a common semi-terrestrial crab in Brazilian mangroves and an important fishery resource for traditional communities in the northeastern Brazilian coast. Aiming to contribute to the knowledge about the species, this study evaluated the carapace width and weight growth curves, the relative growth of weight versus carapace width, and the temporal variation of gonadosomatic and hepatosomatic indices for the species. A total of 524 crabs were collected in a mangrove area of Ubatuba municipality, state of São Paulo.
