Published in 2019 at "Environmental Science and Pollution Research"

DOI: 10.1007/s11356-019-06951-9

Abstract: Coastal wetlands are crucial to global climate change due to their roles in modulating atmospheric concentrations of greenhouse gases (GHGs) (CO 2 , CH 4 , N 2 O). Under a warming climate, we investigated… read more here.

Published in 2017 at "Journal of Sea Research"

DOI: 10.1016/j.seares.2017.06.015

Abstract: Abstract Fecundity is a key aspect of fish species reproductive biology because it relates directly to total egg production. Yet, despite such importance, fecundity estimates are lacking or scarce for several fish species. The gravimetric… read more here.
