Data comprise tree trait data collected during September and October 2016 (the peak dry season), in the Caxiuanã National Forest Reserve, eastern Amazon, Brazil. 17 traits (including plot type, tree species name, diameter at breast height, tree light score, carboxylation capacity, electron transport capacity, leaf respiration in the dark, stomatal conductance, stem CO2 efflux, leaf mass per area, leaf nitrogen and phosphorus content, branch wood density, leaf water potential, xylem pressure, lumen conductance, percentage loss...

The response of carbon assimilation and storage to long-term drought in tropical trees is dependent on light availability

1) Whether tropical trees acclimate to long-term drought stress remains unclear. This uncertainty is amplified if drought stress is accompanied by changes in other drivers such as the increases in canopy light exposure that might be induced by tree mortality or other disturbances. 2) Photosynthetic capacity, leaf respiration, non-structural carbohydrate (NSC) storage and stomatal conductance were measured on 162 trees at the world’s longest running (15 yr) tropical forest drought experiment. We test whether surviving...

Has a river dam affected the life-history traits of a freshwater prawn?

Gicelle Maria Farias Silva, Marcelo Andrade, Breno Silva, Ingrid Palheta, Liziane Gonçalves, Rossineide Rocha & Maria Auxiliadora Ferreira
In recent years, species richness and diversity in aquatic ecosystems has declined as environments are increasingly impacted by anthropic actions. Freshwater prawns are among the aquatic organisms most capable to survive in a heterogeneous environment. Due to factors such as the distance from an estuary or dam, Macrobrachium amazonicum populations in rivers do not show amphidromy. So, the present study investigated the influence of environmental conditions on life-history traits of the Amazon river prawn, M....

Elements of fish metacommunity structure in Neotropical freshwater streams

The identification of the mechanisms underlying co-occurrence patterns of species is a way to identify which processes (niche, neutral or both) structure metacommunities. In this paper, our goals are to identify patterns of co-occurrence in neotropical stream fish and determine which processes structure the metacommunity and the gradients that underlie this structure. Our results pointed out that the metacommunity formed by the total pool of species is structured by a nested pattern (Hyperdispersed Species Loss)...
