Hypogenic Versus Epigenic Subterranean Ecosystem: Lessons From Eastern Iberian Peninsula, Alberto Sendra, Policarp Garay, Vicente M. Ortuño, José D. Gilgado, Santiago Teruel, Ana Sofia P.S. Reboleira

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 Jun 2013

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 …


The Subterranean Fauna Of A Biodiversity Hotspot Region - Portugal: An Overview And Its Conservation, Ana Sofia P.S. Reboleira, Paulo A.V. Borges, Fernando Gonçalves, Artur R.M. Serrano, Pedro Oromí Jun 2013

The Subterranean Fauna Of A Biodiversity Hotspot Region - Portugal: An Overview And Its Conservation, Ana Sofia P.S. Reboleira, Paulo A.V. Borges, Fernando Gonçalves, Artur R.M. Serrano, Pedro Oromí

An overview of the obligate hypogean fauna in Portugal (including Azores and Madeira archipelagos) is provided, with a list of obligated cave-dwelling species and subspecies, and a general perspective about its conservation. All the available literature on subterranean Biology of Portugal since the first written record in 1870 until today has been revised. A total of 43 troglobiont and 67 stygobiont species and subspecies from 12 orders have been described so far in these areas, included in the so-called Mediterranean hotspot of biodiversity. The subterranean fauna in Portugal has been considered moderately poor with some endemic relicts and it remains …


Biologia Subterrânea Em Zonas Cársicas Portuguesas, Ana Sofia P.S. Reboleira, Pedro Oromí, Fernando Gonçalves Mar 2010

Biologia Subterrânea Em Zonas Cársicas Portuguesas, Ana Sofia P.S. Reboleira, Pedro Oromí, Fernando Gonçalves

Ana Sofia P.S. Reboleira

O domínio subterrâneo, composto por uma vasta rede de cavidades e fissuras, alberga um ecossistema peculiar, rico em microendemismos e espécies que exibem adaptações morfofisiológicas à vida em profundidade. Os ecossistemas subterrâneos estão sujeitos a variadas pressões ambientais decorrentes da utilização do solo à superfície. A sensibilidade ecológica que caracteriza as regiões cársicas, acrescida de um conhecimento científico incipiente, traduz-se na irreversível degradação destes ecossistemas. A extensão dos habitats subterrâneos é bastante alargada, contudo a sua Biologia é, em boa medida, desconhecida. O conhecimento actual da Biologia subterrânea das regiões cársicas baseia-se, sobretudo, em trabalhos de taxonomia clássica realizados no …


Qualidade Da Água Da Nascente De Anços (Serra De Sicó) Com O Uso De Fitoperifiton, Ana Sofia P.S. Reboleira Mar 2005

Qualidade Da Água Da Nascente De Anços (Serra De Sicó) Com O Uso De Fitoperifiton, Ana Sofia P.S. Reboleira

Ana Sofia P.S. Reboleira

O estudo diatomológico da nascente do Rio Anços (Serra de Sicó), foi efectuado sazonalmente, entre o Verão de 2002 e o Outono de 2004. Escolheu-se uma estação de colheita, na parede da nascente exposta à água que provém do interior do Maciço. Com o intuito de monitorizar a qualidade da água, foram recolhidas diatomáceas perifíticas. Condutividade, pH, temperatura e oxigénio dissolvido foram medidos na estação em cada colheita efectuada. Vinte e sete espécies, distribuídas por dezasseis géneros foram observados. Cocconeis placentula Ehrenberg var. lineata (Herenberg) Van Heurck foi a espécie dominante, seguida de Navicula minima Grunow, N. cryptotenella Lange-Bertalot, Gomphonema …
