Amphidromy in Shrimps: a Life Cycle Between Rivers and the Sea

Bauer (Guest Editors) DOI: 103856/vol41-issue4-fulltext-2 Review Amphidromy in shrimps: a life cycle between rivers and the sea Raymond T. Bauer1 1Department of Biology, University of Louisiana at Lafayette, Lafayette, Louisiana, 70504-2451 USA ABSTRACT. Amphidromy is a diadromous life history pattern, common in tropical and subtropical freshwater caridean shrimps, in which adults live, breed and spawn small-sized embryos in freshwater but have extended larval development (ELD) in marine waters. Most completely freshwater species spawn large embryos with either direct or abbreviated larval development (ALD). An important benefit of amphidromy is dispersal among river systems via marine larvae, which increases their access to alternative habitats. Thus, amphidromous species have much broader geographic distributions than closely related completely freshwater ones with ALD. ALD and freshwater ELD species appear to have evolved from amphidromous species with marine ancestors. Delivery of larvae to the sea in many amphidromous species is accomplished by upstream hatching and river drift of larvae to the sea. In other species, the females themselves apparently migrate down to marine waters to spawn. After development, the postlarvae must find a river mouth and migrate upstream to the adult habitat. Migrations occur at night, with juveniles swimming or crawling along the river or stream bank. Larvae are released during the wet or flood season of the year, while juvenile migrations take place during the dry or low-flow season. -
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
J. N. Am. Benthol. 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. Covich1 Institute of Ecology, University of Georgia, Athens, Georgia 30602-2202 USA 2 3 Todd A. 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. -
Subterranean Crustacea Decapoda Macrura Collected by Mr. L
Int. J. Speleol. 6 (1974), pp. 231-242. Subterranean Crustacea Decapoda Macrura Collected by Mr. L. Botosaneanu during the 1973 Cuban-Roumanian Biospeological Expedition to Cuba by L. B. HOLTHUIS* To date three expeditions to explore the cave fauna of Cuba have been undertaken under the auspices of the Academies of Sciences of Roumania and Cuba; in 1969, 1970 and 1973. A paper on the cave shrimps collected by the first (1969) expedi- tion has been published (Botosaneanu & Holthuis, 1970). In that paper a review was given of the state of our knowledge of the subterranean shrimp fauna of Cuba as it was at that time, with a list of all species and references to all publications dealing with them. The 1969 expedition not only collected all species of cave shrimps then known from Cuba, but also one that was new to science. The 1973 expedition added one species to this list, the material of which repre- sents an undescribed subspecies. The number of subterranean species of shrimps collected in 1973 is smaller than that obtained in 1969, but interesting range extensions and important data on the ecology of the species could be added. In the present paper not only the shrimps are treated, but crayfishes are includ- ed as well. During the expedition Mr. Botosaneanu also collected 2 species of Macrura in epigean fresh waters, viz., a shrimp, A tya scabra (Leach, 1815) in Rio San Vicente near Vinales, Pinar del Rio Province, and the crayfish Procambarus atkinsoni (Ortmann, 1913) in Arroyo La Talega near Santa Fe, Isla de Pinos. -

AN ENUMERATION OF THE CRUSTACEA DECAPODA NATANTIA INHABITING SUBTERRANEAN WATERS par L.-B. HOLTHUIS Rijksmuseum van Natuurlijke Historié, Leiden, Holland The présent paper provides a list of the macrurous Decapod Crustacea, belonging to the supersection Natantia, that have been found in subterranean waters. The number of such species is quite small, being somewhat more than 40 in ail. Of thèse only part are actual troglobic forms, i.e. animais that are only known from caves and have not, or only incidentally, been found in waters that are exposed to daylight. A second group is formed by species that normally live in surface waters and only occasionally are met with in subterranean habitats. No sharp line can be drawn between thèse two catégories, the more so as at présent still extremely little is known of the biology and of the ecology of most of the species. -
