  • Effects of Drought and Hurricane Disturbances on Headwater Distributions of Palaemonid River Shrimp (Macrobrachium Spp.) in the Luquillo Mountains, Puerto Rico

Crowl AND Tamara Heartsill-Scalley Ecology Center and Department of Aquatic, Watershed, and Earth Sciences, Utah State University, Logan, Utah 84322 USA Abstract. Extreme events (hurricanes, floods, and droughts) can influence upstream migration of macroinvertebrates and wash out benthic communities, thereby locally altering food webs and species interactions. We sampled palaemonid river shrimp (Macrobrachium spp.), dominant consumers in headwaters of the Luquillo Mountains of northeastern Puerto Rico, to determine their distributions along an elevational gradient (274–456 m asl) during a series of disturbances (Hurricane Hugo in 1989, a drought in 1994, and Hurricane Georges in 1998) that occurred over a 15-y period (1988À2002). We measured shrimp abundance 3 to 6 times/y in Quebrada Prieta in the Espiritu Santo drainage as part of the Luquillo Long- Term Ecological Research Program. In general, Macrobrachium abundance declined with elevation during most years. The lowest mean abundance of Macrobrachium occurred during the 1994 drought, the driest year in 28 y of record in the Espiritu Santo drainage. Macrobrachium increased in abundance for 6 y following the 1994 drought. In contrast, hurricanes and storm flows had relatively little effect on Macrobrachium abundance.

  • A Migratory Shrimp's Perspective on Habitat Fragmentation in The
    A MIGRATORY SHRIMP’S PERSPECTIVE ON HABITAT FRAGMENTATION IN THE NEOTROPICS: EXTENDING OUR KNOWLEDGE FROM PUERTO RICO BY MARCIA N. SNYDER1,3), ELIZABETH P. ANDERSON2,4) and CATHERINE M. PRINGLE1,5) 1) Odum School of Ecology, University of Georgia, Athens, Georgia 30602, U.S.A. 2) Global Water for Sustainability Program, Florida International University, Miami, FL 33199, U.S.A. ABSTRACT Migratory freshwater fauna depend on longitudinal connectivity of rivers throughout their life cycles. Amphidromous shrimps spend their adult life in freshwater but their larvae develop into juveniles in salt water. River fragmentation resulting from pollution, land use change, damming and water withdrawals can impede dispersal and colonization of larval shrimps. Here we review current knowledge of river fragmentation effects on freshwater amphidromous shrimp in the Neotropics, with a focus on Puerto Rico and Costa Rica. In Puerto Rico, many studies have contributed to our knowledge of the natural history and ecological role of migratory neotropical shrimps, whereas in Costa Rica, studies of freshwater migratory shrimp have just begun. Here we examine research findings from Puerto Rico and the applicability of those findings to continental Costa Rica. Puerto Rico has a relatively large number of existing dams and water withdrawals, which have heavily fragmented rivers. The effects of fragmentation on migratory shrimps’ distribution have been documented on the landscape-scale in Puerto Rico. Over the last decade, dams for hydropower production have been constructed on rivers throughout Costa Rica. In both countries, large dams restrict shrimps from riverine habitat in central highland regions; in Puerto Rico 27% of stream kilometers are upstream of large dams while in Costa Rica 10% of stream kilometers are upstream of dams.

  • Molecular Evidence for Sequential Colonization and Taxon Cycling In

COOK,* CATHERINE M. PRINGLE† and JANE M. HUGHES* *Australian Rivers Institute, Griffith University, Nathan, Queensland, Australia, †Institute of Ecology, University of Georgia, Athens, GA, USA Abstract Taxon cycling, i.e. sequential phases of expansions and contractions in species’ distributions associated with ecological or morphological shifts, are postulated to characterize dynamic biogeographic histories in various island faunas. The Caribbean freshwater shrimp assemblage is mostly widespread and sympatric throughout the region, although one species (Atyidae: Atya lanipes) is geographically restricted and ecologically and morphologically differentiated from other Atya species. Using patterns of nucleotide variation at the COI mtDNA gene in five species of freshwater shrimp (A. lanipes, A. scabra, A. innocuous; Xiphocarididae: Xiphocaris elongata; Palaemonidae: Macrobrachium faustinum) from Puerto Rico, we expected to detect a signature of sequential colonization in these shrimp, consistent with the concept of taxon cycling, and expected that A. lanipes would be at a different taxon stage (i.e. an early stage species) to all other species. We also examined patterns of genetic population structure in each species expected with poor, intermediate and well-developed abilities for among-river dispersal. Population expansions were detected in all species, although the relative timing of the expansions varied among them. Assuming that population expansions followed colonization of Puerto Rico by freshwater shrimp, results bear the hallmarks of sequential colonization and taxon cycling in this fauna. A.

  • Meta-Analysis: Abundance, Behavior, and Hydraulic Energy Shape Biotic Effects on Sediment Transport in Streams
    Ecology, 96(5), 2015, pp. 1329–1339 Ó 2015 by the Ecological Society of America Meta-analysis: abundance, behavior, and hydraulic energy shape biotic effects on sediment transport in streams 1,3 2 L. K. ALBERTSON AND D. C. ALLEN 1Stroud Water Research Center, Avondale, Pennsylvania 19311 USA 2School of Letters and Sciences, Arizona State University, Mesa, Arizona 85212 USA Abstract. An increasing number of studies have emphasized the need to bridge the disciplines of ecology and geomorphology. A large number of case studies show that organisms can affect erosion, but a comprehensive understanding of biological impacts on sediment transport conditions is still lacking. We use meta-analysis to synthesize published data to quantify the effects of the abundance, body size, and behavior of organisms on erosion in streams. We also explore the influence of current velocity, discharge, and sediment grain size on the strength of biotic effects on erosion. We found that species that both increase erosion (destabilizers) and decrease erosion (stabilizers) can alter incipient sediment motion, sediment suspension, and sediment deposition above control conditions in which the organisms were not present. When abundance was directly manipulated, these biotic effects were consistently stronger in the higher abundance treatment, increasing effect sizes by 66%. Per capita effect size and per capita biomass were also consistently positively correlated. Fish and crustaceans were the most studied organisms, but aquatic insects increased the effect size by 5503 compared to other types of organisms after accounting for biomass. In streams with lower discharge and smaller grain sizes, we consistently found stronger biotic effects. Taken collectively, these findings provide synthetic evidence that biology can affect physical processes in streams, and these effects can be mediated by hydraulic energy.

  • Marine Dispersal Determines the Genetic Population Structure of Migratory Stream Fauna of Puerto Rico: Evidence for Island-Scale Population Recovery Processes

Cook AND Sofie Bernays Australian Rivers Institute, Griffith University, Nathan, Queensland, Australia 4111 Catherine M. Pringle3 Odum School of Ecology, University of Georgia, Athens, Georgia 30602 USA Jane M. Hughes4 Australian Rivers Institute, Griffith University, Nathan, Queensland, Australia 4111 Abstract. Various components of island stream faunas, including caridean shrimps, fish, and gastropods, undertake obligate amphidromous migration, whereby larvae are released in upstream freshwater reaches, drift downstream to estuaries or marine waters, then migrate upstream as postlarvae to freshwater adult habitats. Longitudinal migration from estuaries to headwaters is well documented for many amphidromous species, but the degree of among-river marine dispersal is poorly known for most species. We need better understanding of the potential for marine dispersal in population processes of amphidromous species, particularly recolonization and population recovery in impacted lotic systems, such as those on Puerto Rico, because some theories of dispersal for species with marine larvae predict high rates of self-recruitment. We tested population genetic predictions for widespread marine larval dispersal and self-recruitment to the natal river for 11 amphidromous species, including shrimps, fish, and a gastropod, in Puerto Rico. Population genetic analysis of mitochondrial DNA data showed high rates of gene flow among rivers and indicated that marine dispersal determines the population genetic structure of all 11 species.

Rio Piedras, PR: U.S. Department of Agriculture, Forest Service, International Institute of Tropical Forestry. 30 p. This study develops two habitat-based approaches for evaluating instream-flow require- ments within the Luquillo Experimental Forest in northeastern Puerto Rico. The analysis is restricted to instream-flow requirements in upland streams dominated by the common communities of freshwater decapods. In headwater streams, pool volume was the most consistent factor in predicting the abundance of common freshwater shrimp. In second- and third-order tributaries, both water depth and velocity can be used to define their habitats. The most common species of shrimp are reclusive during the day; at night they prefer areas of low velocity (<0.09 m/s) and areas shallower than 0.4 m.
