Hydraulic Preferences of Shrimps and Fishes in Tropical Insular Rivers

Abstract: Hydraulic habitat models based on the preferences of species for the hydraulic characteristics of their microhabitats are frequently used to evaluate the impact on the habitat of a change in river flow regime. Their application in a tropical insular environment is still limited as little is known about the hydraulic preferences of species. Hydraulic preference models have been developed for 15 taxa (diadromous shrimps and fishes) sampled in 52 rivers in the Caribbean (the French West Indies) and the Indian Oce… Show more

“…Macroinvertebrate diversity and abundance were significantly lower in the HUW than at the LUW and MUW. This difference among the three rivers can probably be explained by limited food availability, habitat loss, and warmer water temperature in conjunction with the flashy discharge regimes; low invertebrate production can be a consequence of high water discharges (Heino et al 2004;Girard et al 2013).…”

“…Stream hydraulic characteristics have been reported as the main factors determining shrimp-assemblage variation in other regions (Kemenes et al, 2010;Novak, Bayliss, Garcia, Pusey, & Douglas, 2017;Richardson & Cook, 2006). Among the hydraulic characteristics, stream velocity is usually the most influential habitat variable and a key factor related to shrimp distribution and composition (Girard et al, 2014;Richardson & Cook, 2006). As a general pattern, M. inpa was more abundant in shallow locations with lower current velocities, while M. nattereri and P. amazonensis were more abundant in deeper places with higher current velocities.…”

“…In lotic ecosystems, specific biota are well recognized, including biofilms (Lear, Anderson, Smith, Boxen, & Lewis, ), diatoms (Passy, ), plankton, meiofauna (Dole‐Olivier, Galassi, Marmonier, & Creuzé des Châtelliers, ), worms (Traunspurger, ), aquatic insects (Gratton & Zanden, ), snails (Cross & Benke, ), bivalves (Sheldon & Walker, ), crustacea (Girard et al, ), and fish (Schlosser & Angermeier, ). In dryland rivers, lotic biota and ecology are less well acknowledged.…”
