Rowley, Marissa (2013) Interspecific Competition Between Prawns in The
Interspecific Competition between Prawns in the Checkhall River Marissa Rowley Dominica 2013 May 18 – June 9 ABSTRACT On the island of Dominica, nature remains virtually untouched by humans. This makes the island an exceptional choice for biological research as well as animal habitats. With its many different ecosystems, numerous animals take refuge throughout the island. Five species of prawns coexist within the Checkhall River on the island of Dominica, two of which lack pincers. In the Checkhall River, I researched competition of prawns for available food sources in different areas of the stream, including shallow areas, deep areas, and waterfall areas. Coconut was tied to fishing line, weighted down with a rock, and used as bait. The bait line was then dropped in chosen areas of the stream and watched for interspecific interactions until a clear winner was present. Multiple trials were held in each designated spot. From the results, it is clear the Macrobrachium species of prawns dominate competition in the Checkhall River. I believe this is because of their larger pincers. Their pincers can be used to obtain and keep hold of a food source and intimidate other species of prawns. This research can be helpful to future biologists studying the behavioral ecology of freshwater prawns. INTRODUCTION Dominica is a relatively small volcanic island located in the Lesser Antillean chain of the Caribbean. Appropriately nicknamed the Nature Island, Dominica is characterized by many different habitats including mountainous terrain, rainforests, waterfalls, lakes, and rivers (Discover Dominica Authority). These different ecosystems make Dominica an exceptional place for field biology research as they remain mostly untouched by humans and modern society. -
Effects of Drought and Hurricane Disturbances on Headwater Distributions of Palaemonid River Shrimp (Macrobrachium Spp.) in the Luquillo Mountains, Puerto Rico

Soc., 2006, 25(1):99–107 Ó 2006 by The North American Benthological Society Effects of drought and hurricane disturbances on headwater distributions of palaemonid river shrimp (Macrobrachium spp.) in the Luquillo Mountains, Puerto Rico Alan P.

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. Key words: dispersal, drainage networks, geomorphology, habitat preference, omnivores, prey refugia. Flow-based events often modify the important roles (Covich et al. -
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. -

Dissertation Advisor: Professor Jonathan Losos Ambika Kamath Phenotypic Variation and the Behavioral Ecology of Lizards Abstract Behavioral ecology is the study of how animal behavior evolves in the context of ecology, thus melding, by definition, investigations of how social, ecological, and evolutionary forces shape phenotypic variation within and across species. Framed thus, it is apparent that behavioral ecology also aims to cut across temporal scales and levels of biological organization, seeking to explain the long-term evolutionary trajectory of populations and species by understanding short-term interactions at the within-population level. In this dissertation, I make the case that paying attention to individuals’ natural history— where and how individual organisms live and whom and what they interact with, in natural conditions—can open avenues into studying the behavioral ecology of previously understudied organisms, and more importantly, recast our understanding of taxa we think we know well. -

Phylogeny, Ecomorphological Evolution, and Historical Biogeography of the Anolis Cristatellus Series

BRANDLEY^''^'"' AND KEVIN DE QUEIROZ^ ^Sam Noble Oklahoma Museum of Natural History and Department of Zoology, The University of Oklahoma, Norman, OK 73072, USA ^Department of Zoology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20,560, USA ABSTRACT: TO determine the evolutionary relationships within the Anolis cristatellus series, we employed phylogenetic analyses of previously published karyotype and allozyme data as well as newly collected morphological data and mitochondrial DNA sequences (fragments of the 12S RNA and cytochrome b genes). The relationships inferred from continuous maximum likelihood reanalyses of allozyme data were largely poorly supported. A similar analysis of the morphological data gave strong to moderate support for sister relationships of the two included distichoid species, the two trunk-crown species, the grass-bush species A. poncensis and A. pulchellus, and a clade of trunk-ground and grass-bush species. The results of maximum likelihood and Bayesian analyses of the 12S, cyt b, and combined mtDNA data sets were largely congruent, but nonetheless exhibit some differences both with one another and with those based on the morphological data. We therefore took advantage of the additive properties of likelihoods to compare alternative phylogenetic trees and determined that the tree inferred from the combined 12S and cyt b data is also the best estimate of the phylogeny for the morphological and mtDNA data sets considered together. We also performed mixed-model Bayesian analyses of the combined morphology and mtDNA data; the resultant tree was topologically identical to the combined mtDNA tree with generally high nodal support. -
