Over the last 40 years, hypogenic karst/caves have become well known and hypogene speleogenesis has been used to explain the formation of some of the largest subterranean maze caves. These hypogenic systems involve confined aquifers with upwards flow, responsible for their karstification. Such spaces begun and could be remain isolated from the surface and the contiguous subterranean habitats, including the shallow ones. We studied the invertebrate fauna and the geology/speleogenesis of two recently opened caves from Eastern Iberian Peninsula, which clearly showed features of hypogenic origin. Their scarce faunistic composition, formed by non cave-adapted fauna, is similar to other hypogenic …
The World’S Deepest Subterranean Community - Krubera-Voronja Cave (Western Caucasus), Alberto Sendra, Ana Sofia P.S. Reboleira
The World’S Deepest Subterranean Community - Krubera-Voronja Cave (Western Caucasus), Alberto Sendra, Ana Sofia P.S. Reboleira

Subsurface biota extends over a wide variety of habitats that can be spatially interconnected. The largest communities of this subsurface biota inhabit cavities and are well known mainly in caves where biologists are able to have access. Data about deep subterranean communities and arthropods living under one thousand meters was unknown. An expedition to world’s deepest cave, Krubera-Voronja in Western Caucasus, revealed an interesting subterranean community, living below 2000 meters and represented by more than 12 species of arthropods, including several new species for science. This deep cave biota is composed of troglobionts and also epigean species, that can penetrate …
Subterranean Species Of Acipes Attems, 1937 (Diplopoda, Julida, Blaniulidae), Henrik Enghoff, Ana Reboleira
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

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 …

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 …

A catalogue of arachnid type specimens of the collection kept at the Department of Animal Biology, University of La Laguna (Spain) is presented. It harbours type material of 104 species belonging to 23 families of arachnids, represented by 21 holotypes and 164 paratypes for 23 species of pseudoscorpions, and 49 holotypes, 218 paratypes and 3 syntypes for 81 species of spiders. This collection is using the criteria and standards of the Global Biodiversity Information Facility (GBIF) for cataloguing and computerization of the specimens. Type specimens were checked with the original descriptions, and relevant additional information from original labels not included …
Lusoblothrus, A New Syarinid Pseudoscorpion Genus (Arachnida) From Portugal, Occupying An Isolated Position Within The Holarctic Fauna, Ana Reboleira, Juan Zaragoza, Fernando Gonçalves, Pedro Oromí
Lusoblothrus, A New Syarinid Pseudoscorpion Genus (Arachnida) From Portugal, Occupying An Isolated Position Within The Holarctic Fauna, Ana Reboleira, Juan Zaragoza, Fernando Gonçalves, Pedro Oromí
Ana Sofia P.S. Reboleira
The new pseudoscorpion genus Lusoblothrus of the family Syarinidae is described from a cave in the Algarve region, southern Portugal, to accommodate L. aenigmaticus sp. nov., whose morphological affinities within the Holarctic syarinid fauna are not clear and resembles the Gondwanan genera. This discovery emphasizes the relevance of the Algarve region as a hotspot for relictual hypogean fauna within the Iberian Peninsula.
Squamatinia Algharbica Gen. N. Sp. N., A Remarkable New Coletiniinae Silverfish (Zygentoma: Nicoletiidae) From Caves In Southern Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí, Luís Mendes
Squamatinia Algharbica Gen. N. Sp. N., A Remarkable New Coletiniinae Silverfish (Zygentoma: Nicoletiidae) From Caves In Southern Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí, Luís Mendes
Ana Sofia P.S. Reboleira
A new genus of Coletiniinae silverfish (Nicoletiidae) similar to Coletinia Wygodzinsky and Lepidospora Escherich is described to accommodate the new species Squamatinia algharbica gen. n. sp. n. Many individuals were collected over all seasons of the year in four caves of the Algarve karst massif in the south of Portugal. An identification key for the known genera of Coletiniinae is provided, as well as some biogeographical and ecological comments.
The Effect Of Environmental Parameters And Cyanobacterial Blooms On Phytoplankton Dynamics Of A Portuguese Temperate Lake, Daniela De Figueiredo, Ana Reboleira, S. Antunes, N. Abrantes, U. Azeiteiro, F. Gonçalves, M. Pereira
The Effect Of Environmental Parameters And Cyanobacterial Blooms On Phytoplankton Dynamics Of A Portuguese Temperate Lake, Daniela De Figueiredo, Ana Reboleira, S. Antunes, N. Abrantes, U. Azeiteiro, F. Gonçalves, M. Pereira

The increasing occurrence of cyanobacterial blooms in freshwaters is of great concern due to the ability of many cyanobacteria to produce cyanotoxins. In the present work, the eutrophied Vela Lake (Central Portugal), used for recreational purposes and as a water source for agriculture, was monitored every fortnight between 2000 and 2001. Phytoplankton diversity and densities were measured and correlated to environmental parameters. A seasonal phytoplanktonic succession was observed and it was mainly correlated with conductivity, temperature, total suspended solids and nutrients availability (particularly phosphorus). Diatoms were dominant during winter months (inferior temperatures and higher nutrients availability) followed by green algae …
