Relationship between isoprene emission and photosynthesis in diatoms, and its implications for global marine isoprene estimates
Global consensus estimates of marine isoprene emission (~ 1 TgC yr− 1) is significantly smaller than terrestrial isoprene emission (~ 500 TgC yr− 1), and the reasons are unclear. With the premise that isoprene emission is ...
Differentiation in reproductive traits of geminatemangrove crabs of the genus Aratus (Decapoda: Brachyura)across the Central American Isthmus
The mangrove crab Aratus pisonii was considered to have an amphi-American distribution; however, a recent study revealed that the Eastern Tropical Pacific populations were genetically distinct, thus representing a new ...
