Secondary production, longevity and resource consumption rates of freshwater shrimps in two tropical streams with contrasting geomorphology and food web structure

Freshwater Biology, 53(12), 2504–2519.

By: W. Cross*, A. Covich*, T. Crowl*, J. Benstead* & A. Ramírez*

author keywords: Atya; bioenergetics; Luquillo Experimental Forest; Puerto Rico; Xiphocaris
TL;DR: A minimum longevity model was constructed to explore the likely minimum life spans of the two dominant taxa (Atya spp. and Xiphocaris elongata) and a bioenergetics model was used to quantify annual consumption rates of major basal resources by the two taxa. (via Semantic Scholar)

Toward Quantifying the Relative Importance of Invertebrate Consumption and Bioturbation in Puerto Rican Streams

Biotropica, 40(4), 477–484.

By: W. Cross*, A. Ramírez*, A. Santana* & L. Santiago*

Contributors: W. Cross*, A. Ramírez*, A. Santana* & L. Santiago*

author keywords: Atyidae; bioenergetics; Caribbean; Decapoda; detritus; ecosystem engineer; freshwater shrimps; island; mayflies; tropical stream
TL;DR: This study suggests that bioturbation is the dominant process that redistributes and entrains fine particles after storm events, and that a variable fraction of deposited and accrued benthic material may be consumed during base-flow conditions. (via Semantic Scholar)

By: A. Ramírez* & C. Pringle*

Contributors: A. Ramírez* & C. Pringle*

TL;DR: The increase in larval biomass turnover along the phosphorus gradient indicates that a gradient of increasing energy flow exists from detrital-based resources to primary consumers and a potential gradient of increase energy flow from primary consumers to upper trophic levels as phosphorus increases.

TL;DR: The results, and those of previous experiments in the study stream, suggest that nighttime drift is driven by the presence of predatory diurnal drift-feeding fishes and nocturnal adult shrimps, suggesting that benthic communities are subject to similar stresses throughout the year, and that populations grow and reproduce continuously.
