Millipedes (Diplopoda) from Caves of Portugal
A.S.P.S. Reboleira and H. Enghoff – Millipedes (Diplopoda) from caves of Portugal. Journal of Cave and Karst Studies, v. 76, no. 1, p. 20–25. DOI: 10.4311/2013LSC0113 MILLIPEDES (DIPLOPODA) FROM CAVES OF PORTUGAL ANA SOFIA P.S. REBOLEIRA1 AND HENRIK ENGHOFF2 Abstract: Millipedes play an important role in the decomposition of organic matter in the subterranean environment. Despite the existence of several cave-adapted species of millipedes in adjacent geographic areas, their study has been largely ignored in Portugal. Over the last decade, intense fieldwork in caves of the mainland and the island of Madeira has provided new data about the distribution and diversity of millipedes. A review of millipedes from caves of Portugal is presented, listing fourteen species belonging to eight families, among which six species are considered troglobionts. The distribution of millipedes in caves of Portugal is discussed and compared with the troglobiont biodiversity in the overall Iberian Peninsula and the Macaronesian archipelagos. INTRODUCTION All specimens from mainland Portugal were collected by A.S.P.S.

Is Ellipura Monophyletic? a Combined Analysis of Basal Hexapod

The Role of Microhabitats in Structuring Cave Invertebrate Communities in Guatemala Gabrielle S.M

They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live in subterranean habitats. Using 30 m2 transects, the invertebrate fauna was collected and the substrate features were measured. The results showed that community responded to the presence of guano, cobbles, boulders, and substrate heterogeneity. The positive relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for structuring invertebrate cave communities in Guatemalan caves. -

Fax: (57) 67462563; [email protected] Recibido 27-IV-2000. Corregido 9-X-2000. Aceptado 23-X-2000. Abstract: The trophic and reproductive ecology of catfish (Trichomycterus caliense and Astroblepus cyclopus) was studied in the Quindio River upper Basin, Alto Cauca, Colombia. The pH was neutral, water oxygen content high (8.4 ppm) and temperature in the habitats was 18.63 ºC; both species are nonmigratory and sympatric with four other fish species. The ovaries mature primarily between May and September in T. caliense; between Decem- ber and May in A. cyclopus. The mean size at maturity is 8.3 cm (standard length) in T. caliense and 6.0 cm (stan- dard length) in A. cyclopus; the sex ratio is 1:1 in T. caliense (X2=3.4, P≥0.05) and in A. cyclopus (X2=1.44, P≥0.1); the fecundity is low (191 and 113 oocytes respectively) and the eggs are small (1.5 and 2.39 mm respectively). The fishes are insectivorous and specialize in Coleoptera, Diptera and Trichoptera; Spearman Rank Correlation Coeffi- cients (rs=0.464) indicated that there are differences (T= 2.5148, P<0.01) between their diets; both taxa did not agree with the expected trophic habits for sympatric species that are morphologically similar and related in the sa- me trophic level. -

A New Species of Cave Adapted Nicoletiid (Zygentoma: Insecta) from Sistema Huautla, Oaxaca, Mexico: the Tenth Deepest Cave in the World
L. Espinasa and N.H. Vuong ± A new species of cave adapted Nicoletiid (Zygentoma: Insecta) from Sistema Huautla, Oaxaca, Mexico: the tenth deepest cave in the world. Journal of Cave and Karst Studies, v. 70, no. 2, p. 73±77. A NEW SPECIES OF CAVE ADAPTED NICOLETIID (ZYGENTOMA: INSECTA) FROM SISTEMA HUAUTLA, OAXACA, MEXICO: THE TENTH DEEPEST CAVE IN THE WORLD LUIS ESPINASA AND NGUYET H. VUONG School of Science, Marist College, 3399 North Road, Poughkeepsie, NY 12601, [email protected] and [email protected] Abstract: Anelpistina specusprofundi, n. sp., is described and separated from other species of the subfamily Cubacubaninae (Nicoletiidae: Zygentoma: Insecta). The specimens were collected in SoÂtano de San AgustõÂn and in Nita Ka (Huautla system) in Oaxaca, MeÂxico. This cave system is currently the tenth deepest in the world. It is likely that A.specusprofundi is the sister species of A.asymmetrica from nearby caves in Sierra Negra, Puebla. The new species of nicoletiid described here may be the key link that allows for a deep underground food chain with specialized, troglobitic, and comparatively large predators suchas thetarantula spider Schizopelma grieta and the 70 mm long scorpion Alacran tartarus that inhabit the bottom of Huautla system. INTRODUCTION 760 m, but no human sized passage was found that joined it into the system. The last relevant exploration was in Among international cavers and speleologists, caves 1994, when an international team of 44 cavers and divers that surpass a depth of minus 1,000 m are considered as pushed its depth to 1,475 m.

Poughkeepsie, New York, USA 3210 Washington St., Killeen, TX 76541 Abstract While many cave-adapted organisms tend to be endemic to single locations or restricted to single karstic regions, the tro- globitic silverfish insects of genus Texoreddellia can be found in scores of different cave localities that cover a range of nearly 160,000 km2. They are among the most important and common representatives of the cave-adapted fauna of Texas and Coahuila, in northern Mexico. Using morphological and mitochondrial gene sequence data, we have corroborated the presence of at least six different species within the genus and provided species identifications to populations inhabiting 153 different cave locations. Results show that species ranges are larger than previously reported and that ranges tend to greatly overlap with each other. We have also found that different species of Texoreddellia commonly inhabit the same cave in sympatry. Data supports that some species of Texoreddellia can easily disperse through the extensive network of cracks, fissures and smaller cavities near the surface and epikarst. -
Distribution and Habitat Suitability Index Model for the Andean Catfish Astroblepus Ubidiai (Pisces: Siluriformes) in Ecuador
Distribution and habitat suitability index model for the Andean catfish Astroblepus ubidiai (Pisces: Siluriformes) in Ecuador Luis A. Vélez-Espino Environmental and Resource Studies Program, Trent University, Peterborough, Ontario, K9J 7B8, Canada. Fax: 1(705) 748-1026; 1(705) 748-1569; [email protected] Current address: 70 Chesterton Lane. Guelph, Ontario, N1E 7A6. Tel. (519) 780-1681. Received 03-III-2003. Corrected 19-XII-2003. Accepted 12-III-2004. Abstract. In conservation biology there is a basic need to determine habitat suitability and availability. Astroblepus ubidiai (Siluriforms), the only native fish in the highlands of Imbabura province in the Ecuadorian Andes, was abundant in the past in the Imbakucha watershed and adjacent drainages, but currently it is restricted to a few isolated refuges. Conservation actions are needed if this unique fish is to persist. A Habitat Suitability Index (HSI) for the species has been developed in order to aid management decisions. In this HSI model biomass density (B) was selected as a better indicator of habitat quality than either abundance or density. A population well-being index (PI) was constructed with the combination of B and an indicator of fish health (proportion of fish in the population with parasites and deformities). Based in other models of benthic fish the habitat variables current velocity, flow, depth, width, cover, invertebrate composition, vegetation type, terrestrial vegetation, land use, substrate, temperature, pH, TDS, oxygen, altitude, and slope were included in the analysis. An anthropogenic perturbation index (H) and a fragment isolation index (FII) were developed and included as habitat variables as well. The HSI model was applied to refuges and a sample of 15 aquatic bodies without fish populations within the study region.
