Monitoring arthropods in protected grasslands: comparing pitfall trapping, quadrat sampling and video monitoring
Summary: Arthropod monitoring in protected areas often requires non-destructive methods in order to avoid detrimental effects on natural communities. Video monitoring recorded the highest number of individuals followed by quadrat sampling and pitfall trapping. Quadrat sampling showed the highest diversity followed by video monitoring and pitfall trapping. Thus, video monitoring has a great potential as a supplementary method for biodiversity assessments especially at the level of parataxonomic units.

Element uptake, accumulation, and resorption in leaves of mangrove species with different mechanisms of salt regulation
Summary: Populations of Rhizophora mangle (salt-excluding) and Laguncularia racemosa (salt-secreting) in the Maracaibo strait in Venezuela showed: 1) significantly larger succulence in adult leaves of Laguncularia; 2) higher concentrations of N, K, and Mg in Rhizophora and higher P, Na, Ca, and S in Laguncularia; 3) both species resorbed C, N, P and K and accumulated S, Na, Mg, Ca, Mn, and Fe. Compared to Laguncularia, Rhizophora restricted Na and S uptake, resorbed more P, and accumulated Fe.
