ABSTRACT The tip of the South American cone is one of the most interesting Subantarctic areas, both biogeographically and ecologically. Nonetheless, knowledge of the area’s biodiversity, in particular that of the subtidal marine habitats, remains poor. Therefore, in 2004, a biodiversity research project was carried out as a part of the cruise Cimar-10 Fjords, organized and supported by the Chilean National Oceanographic Committee (CONA). The results of the subtidal marine mollusk surveys are presented herein. The samples were collected aboard the Agor 60 “Vidal Gormaz” in winter 2004. The study area covered the northern Chilean Patagonia from Seno de Relocanví (41º31’S) to Boca del Guafo (43º49’S), on the continental shelf from 22 to 353 m depth. The Mollusca were collected at 23 sampling sites using an Agassiz trawl. In total, 67 -
Distribution Patterns, Carbon Sources and Niche Partitioning in Cave Shrimps (Atyidae: Typhlatya) E
www.nature.com/scientificreports OPEN Distribution patterns, carbon sources and niche partitioning in cave shrimps (Atyidae: Typhlatya) E. M. Chávez‑Solís1,2, C. Solís3, N. Simões2,4,5 & M. Mascaró2,4* Cave shrimps of the Typhlatya genus are common and widespread in fresh, brackish and marine groundwater throughout the Yucatan Peninsula (Mexico). These species are ideal models to test niche partitioning within sympatric species in oligotrophic systems. Nevertheless, their food sources remain unidentifed, and despite their frequency and functional importance, distribution and abundance patterns of these species within caves have not been fully recognized. Here, we describe the abundance of three Typhlatya species in diferent temporal and spatial scales, investigate changes in water conditions, and potential sources of carbon as an indication of food origin. Species composition and abundance varied markedly in space and time revealing patterns that difered from one system to another and in relation to environmental parameters. Isotope analysis showed that each species refects a particular δ13C and Δ14C fngerprint, suggesting they feed in diferent proportions from the available carbon sources. Overall, our fndings suggest a niche partitioning of habitat and feeding sources amongst the three Typhlatya species investigated, where environmental characteristics and physiological diferences could play an important role governing their distribution patterns. Te lack of photosynthesis in caves and the resulting limitation in food sources is one of the strongest selection pressures and drivers of evolution for life in caves1. Competition for nutrients in oligotrophic environments, such as anchialine ecosystems—defned as subterranean estuaries that extend inland to the limit of seawater penetration2, certainly requires a unique set of specialization traits that allow for niche partitioning amongst stygobionts (aquatic species strictly bound to the subterranean habitat). -

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province. -
Characterization of Hydrothermal Vent Faunal Assemblages in the Mariana Back-Arc Spreading Centre
Characterization of hydrothermal vent faunal assemblages in the Mariana Back-Arc Spreading Centre by Thomas Normand Giguère B.Sc., University of Guelph, 2017 A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE in the School of Earth and Ocean Sciences © Thomas Normand Giguère, 2020 University of Victoria All rights reserved. This thesis may not be reproduced in whole or in part, by photocopy or other means, without the permission of the author. ii Supervisory Committee Characterization of hydrothermal vent faunal assemblages in the Mariana Back-Arc Spreading Centre by Thomas Normand Giguère B.Sc. University of Guelph, 2017 Supervisory Committee Dr. Verena Tunnicliffe, School of Earth and Ocean Sciences Supervisor Dr. John Dower, School of Earth and Ocean Sciences Departmental Member Dr. Brian Starzomski, School of Environmental Studies Outside Member iii Abstract Researchers have learned much about the biological assemblages that form around hydrothermal vents. However, identities of species in these assemblages and their basic ecological features are often lacking. In 2015, the first leg of the Hydrothermal Hunt expedition identified likely new vent sites in the Mariana Back-arc Spreading Center (BASC). In 2016, the second leg of the expedition used a remotely operated vehicle (ROV) to confirm and sample two new sites and two previously known sites. My first objective is to identify the animals collected from these four vent sites. In these samples, I identify 42 animal taxa, including the discovery of four new vent-associated species, five potentially new species and six taxa not previously reported in the Mariana BASC vents. -

Determining the spatial and seasonal influences of microbial community composition and structure from the Hawaiian anchialine ecosystem by Stephanie Kimie Hoffman A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama December 10, 2016 Keywords: anchialine, microbial ecology, Hawaii, laminated mat, spatial variation, seasonal variation Copyright 2016 by Stephanie Kimie Hoffman Approved by Scott R Santos, Chair, Professor of Biological Sciences Mark R Liles, Professor of Biological Sciences Todd D Steury, Associate Professor of Wildlife Sciences Robert S Boyd, Professor and Undergraduate Program Officer of Biological Sciences Abstract Characterized as coastal bodies of water lacking surface connections to the ocean but with subterranean connections to the ocean and groundwater, habitats belonging to the anchialine ecosystem occur worldwide in primarily tropical latitudes. Such habitats contain tidally fluctuating complex physical and chemical clines and great species richness and endemism. The Hawaiian Archipelago hosts the greatest concentration of anchialine habitats globally, and while the endemic atyid shrimp and keystone grazer Halocaridina rubra has been studied, little work has been conducted on the microbial communities forming the basis of this ecosystem’s food web. Thus, this dissertation seeks to fill the knowledge gap regarding the endemic microbial communities in the Hawaiian anchialine ecosystem, particularly regarding spatial and seasonal influences on community diversity, composition, and structure. Briefly, Chapter 1 introduces the anchialine ecosystem and specific aims of this dissertation. In Chapter 2, environmental factors driving diversity and spatial variation among Hawaiian anchialine microbial communities are explored. Specifically, each sampled habitat was influenced by a unique combination of environmental factors that correlated with correspondingly unique microbial communities. -
Shrimps Down Under: Evolutionary Relationships of Subterranean Crustaceans from Western Australia (Decapoda: Atyidae: Stygiocaris)
Shrimps Down Under: Evolutionary Relationships of Subterranean Crustaceans from Western Australia (Decapoda: Atyidae: Stygiocaris) Timothy J. Page1*, William F. Humphreys2, Jane M. Hughes1 1 Australian Rivers Institute, Griffith University, Nathan, Queensland, Australia, 2 Western Australian Museum, Welshpool DC, Western Australia, Australia Abstract Background: We investigated the large and small scale evolutionary relationships of the endemic Western Australian subterranean shrimp genus Stygiocaris (Atyidae) using nuclear and mitochondrial genes. Stygiocaris is part of the unique cave biota of the coastal, anchialine, limestones of the Cape Range and Barrow Island, most of whose nearest evolutionary relations are found in coastal caves of the distant North Atlantic. The dominance of atyids in tropical waters and their food resources suggest they are pivotal in understanding these groundwater ecosystems. Methodology/Principle Findings: Our nuclear and mitochondrial analyses all recovered the Mexican cave genus Typhlatya as the sister taxon of Stygiocaris, rather than any of the numerous surface and cave atyids from Australia or the Indo-Pacific region. The two described Stygiocaris species were recovered as monophyletic, and a third, cryptic, species was discovered at a single site, which has very different physiochemical properties from the sites hosting the two described species. Conclusions/Significance: Our findings suggest that Stygiocaris and Typhlatya may descend from a common ancestor that lived in the coastal marine habitat of the ancient Tethys Sea, and were subsequently separated by plate tectonic movements. This vicariant process is commonly thought to explain the many disjunct anchialine faunas, but has rarely been demonstrated using phylogenetic techniques. The Cape Range’s geological dynamism, which is probably responsible for the speciation of the various Stygiocaris species, has also led to geographic population structure within species. -
A New Locality and Phylogeny of the Stygobitic Typhlatya Shrimps for the Yucatan Peninsula
Espinasa et al. A new locality and phylogeny of the stygobitic Typhlatya shrimps for the Yucatan Peninsula Luis Espinasa1,2, Efraín M. Chávez Solís3, Maite Mascaró4, Carlos Rosas4, Nuno Simoes4, & Gregory Violette1 1 School of Science, Marist College, 3399 North Rd, Poughkeepsie, New York 12601, USA 2 [email protected] (corresponding author) 2 Posgrado en Ciencias Biológicas, Universidad Nacional Autónoma de México, Avenida Universidad 3000, Copilco-Universidad, Ciudad de México 04510, México 3 Unidad Multidisciplinaria de Docencia e Investigación, Facultad de Ciencias, Universidad Nacional Autónoma de México, Sisal 97355, Yucatán, México Key Words: Troglobite, stygobite, anchialine, histone, shrimp, cave. Typhlatya is a genus of small, stygobitic shrimp in the family Atyidae. Species in this genus are found in subterranean anchialine habitats, and they span salt, brackish and fresh waters. None have been reported in the open sea (Botello et al. 2013). Phylogenetic studies indicate that the genus, as presently defined, is paraphyletic and needs to be redefined, as two of its 17 described species cluster with members of different genera: Typhlatya galapagensis Monod & Cals, 1970 clusters with the widespread Halocaridina and T. monae Chace, 1954 likely clusters with the Australian Stygiocaris (Botello et al. 2013; Jurado-Rivera et al. 2017). Typhlatya species often have very small ranges, limited to single caves, islands, or portions of a coast (Botello et al. 2013). The genus has a broad distribution in many coastal subterranean habitats. Species are found in the West Mediterranean region (France and Spain), West Indian Ocean (Zanzibar), Caribbean region (the Antilles, Bahamas and Yucatán), south Atlantic sea (Ascension Island) and the Galápagos (Botello et al.
