A New Cave-Dwelling Millipede Of The Genus Scutogona From Central Portugal (Diplopoda, Chordeumatida, Chamaesomatidae), Ana Reboleira, Henrik Enghoff Oct 2013

A New Cave-Dwelling Millipede Of The Genus Scutogona From Central Portugal (Diplopoda, Chordeumatida, Chamaesomatidae), Ana Reboleira, Henrik Enghoff

Ana Sofia P.S. Reboleira

A new cave-dwelling species of the genus Scutogona Ribuat, 1913, S. minor n. sp., is described from caves of Sicó karst in central Portugal. The classification and delimitation of Scutogona vis-à-vis related genera, in particular Meinerteuma Mauriès, 1982, is discussed.

On Hypogean Roncocreagris (Arachnida: Pseudoscorpiones: Neobisiidae) From Portugal, With Descriptions Of Three New Species, Ana Reboleira, Juan Zaragoza, Fernando Gonçalves, Pedro Oromí Jun 2013

On Hypogean Roncocreagris (Arachnida: Pseudoscorpiones: Neobisiidae) From Portugal, With Descriptions Of Three New Species, Ana Reboleira, Juan Zaragoza, Fernando Gonçalves, Pedro Oromí

Ana Sofia P.S. Reboleira

Three new hypogean species of the Iberian genus Roncocreagris Mahnert, 1974 are described from mainland Portugal: R. borgesi sp. nov. and R. gepesi sp. nov. from caves in the Sicó massif, and R. occidentalis sp. nov. from caves in the Montejunto and Cesaredas karst plateau. This brings to nine the number of known hypogean species of the mostly Iberian genus Roncocreagris: five from Portugal and four from Spain. Ecological comments and new localities for some of the previously known species are also included.

Subterranean Species Of Acipes Attems, 1937 (Diplopoda, Julida, Blaniulidae), Henrik Enghoff, Ana Reboleira Apr 2013

Subterranean Species Of Acipes Attems, 1937 (Diplopoda, Julida, Blaniulidae), Henrik Enghoff, Ana Reboleira

Ana Sofia P.S. Reboleira

Two new blind, cave-dwelling species of the genus Acipes Attems, 1937, are described from the Algarve, southern Portugal: A. machadoi n. sp. and A. bifilum n. sp. Acipes andalusius Enghoff & Mauriès, 1999, is reported from the mesovoid shallow substratum in Alicante (Spain), 250 km from the type locality in Andalusia.

The Genus Boreviulisoma Brolemann, 1928—An Iberian-N African Outlier Of A Mainly Tropical Tribe Of Millipedes (Diplopoda: Polydesmida: Paradoxosomatidae), Ana Reboleira, Henrik Enghoff Apr 2013

The Genus Boreviulisoma Brolemann, 1928—An Iberian-N African Outlier Of A Mainly Tropical Tribe Of Millipedes (Diplopoda: Polydesmida: Paradoxosomatidae), Ana Reboleira, Henrik Enghoff

Ana Sofia P.S. Reboleira

The genus Boreviulisoma Brolemann, 1928, is revised. The synonymy of Liliputia Attems, 1952, under Boreviulisoma is confirmed, but L. badia Attems, 1951, from Spain, is resurrected, as Boreviulisoma badium, from synonymy under B. liouvilleiBrolemann, 1928 (the type species of Boreviulisoma) from Morocco. Boreviulisoma barrocalense n. sp. is described from the subterranean environment of the Algarve, the southernmost province of Portugal. The distribution of the three known species of Boreviulisoma is mapped, main characters of the genus and its species are reviewed and a key to species of the genus is included. The isolated occurrence of Boreviulisoma badium and B. barrocalense …

Gonadal Cycle Of Northern Quahogs, Mercenaria Mercenaria (Linne, 1758), From Fished And Non-Fished Subpopulations In Narragansett Bay, Dora Marroquin-Mora, Michael Rice Apr 2013

Gonadal Cycle Of Northern Quahogs, Mercenaria Mercenaria (Linne, 1758), From Fished And Non-Fished Subpopulations In Narragansett Bay, Dora Marroquin-Mora, Michael Rice

Michael A Rice

To determine if population density in areas closed to fishing in Narragansett Bay is causing differences in the reproductive potential of the organisms, this study used two approaches to determine the reproductive condition of the animals. The first approach consisted in employing a gravimetric condition index (CI) to evaluate the general condition of quahogs from nine different sites, 3 sites open conditionally for fishing (conditional areas) and 6 sites closed to fishing. The second approach was a determination of gonadal index (GI) of a subset of the sample sites, by histological observation of gonadal tissue sections. Initial sampling included determination …

Acute Toxicity Of Copper Sulfate And Potassium Dichromate On Stygobiont Proasellus: General Aspects Of Groundwater Ecotoxicology And Future Perspectives, Ana Reboleira, Nelson Abrantes, Pedro Oromí, Fernando Gonçalves Mar 2013

Acute Toxicity Of Copper Sulfate And Potassium Dichromate On Stygobiont Proasellus: General Aspects Of Groundwater Ecotoxicology And Future Perspectives, Ana Reboleira, Nelson Abrantes, Pedro Oromí, Fernando Gonçalves

Ana Sofia P.S. Reboleira

Karst systems harbor large groundwater resources for human consumption and represent an important habitat for rare and unprotected specialized animals, the so-called stygofauna. Due to the highly adapted features towards underground life, together with the geographic isolation provided by the subterranean aquifers, groundwater-dwelling animals may lose the ability to face sudden changes on their ecosystems, and therefore the risk of extinction is remarkably high. A little is known about their sensitiveness, especially linked to contamination pressure in urbanized karst areas. Understanding the impact of contaminants on stygofauna is important for setting groundwater environmental quality and management of karst systems. We …

Genome Sequence Of Lactobacillus Pentosus Kca1: Vaginal Isolate From A Healthy Premenopausal Woman, Kingsley Anukam Mar 2013

Genome Sequence Of Lactobacillus Pentosus Kca1: Vaginal Isolate From A Healthy Premenopausal Woman, Kingsley Anukam

Kingsley C Anukam

The vaginal microbiota, in particular Lactobacillus species, play an important role in female health through modulation of immunity, countering pathogens and maintaining a pH below 4.7. We report the isolation and genome sequence of Lactobacillus pentosus strain KCA1 (formally known as L. plantarum) from the vagina of a healthy Nigerian woman. The genome was sequenced using Illumina GA II technology. The resulting 16,920,226 paired-end reads were assembled with the Velvet tool. Contigs were annotated using the RAST server, and manually curated. A comparative analysis with the available genomes of L. pentosus IG1 and L. plantarum WCFS1 showed that over 15% …

Literature Survey, Bibliographic Analysis And A Taxonomic Catalogue Of Subterranean Fauna From Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí Jan 2013

Literature Survey, Bibliographic Analysis And A Taxonomic Catalogue Of Subterranean Fauna From Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí

Ana Sofia P.S. Reboleira

A bibliographic analysis of the hypogean biological studies in Portugal is made, compiling 138 publications related to the subterranean invertebrate fauna, since its begining in 1870 until November 2012. A catalogue of hypogean endemic taxa is provided, listing 27 troglobionts and 63 stygobionts, described to be obligate hypogean and endemic from mainland Portugal (Macaronesian archipelagos excluded). The first impetus on troglobiont studies was provided by the prospections of Barros Machado during 1940’s and by an expedition of Lindberg in the spring of 1961; and the major information about stygobiont species was provided by the former Instituto de Zoologia “Dr. Augusto …
