- Biodiversidad, regiones y conservación de la fauna subterránea hispano-lusaPublication . Sendra, Alberto; Achurra, Ainara; Barranco, Pablo; Beruete, Enrique; Borges, Paulo A. V.; Herrero-Borgoñón, Juan J.; Camacho, Ana I.; Galán, Carlos; Garcia, Lluc; Jaume, Damià; Jordana, Rafael; Modesto, Juan; Monsalve, M. A.; Oromí, Pedro; Ortuño, Vicente M.; Prieto, Carlos; Reboleira, Ana Sofia; Rodríguez, Pilar; Salgado, José M.; Teruel, Santigo; Tinaut, Alberto; Zaragoza, Juan A.El primer Encuentro Ibérico de Biología Subterránea, celebrado en Valencia el pasado julio de 2009, logró reunir un nutrido elenco de investigadores y profesionales en diversos aspectos de la Biología Subterránea que trabajan en España y Portugal. Entre los objetivos del citado encuentro se pretendía publicar los resúmenes de las ponencias que abordaron la biodiversidad, distribución y aspectos de conservación de la fauna y flora del medio subterráneo de la Península Ibérica e islas Baleares, Canarias y Azores. Sin embargo, no todos los grupos y regiones biogeográficas quedaron representados en el encuentro de Valencia, por lo que se decidió proponer la colaboración a otros especialistas. El siguiente artículo nos aproxima de forma breve y concisa al estado actual de los conocimientos en el campo de la biología subterránea hispano-lusa completado. Textos que se acompañan de una selección de referencias y material gráfico. En la redacción del artículo se ha querido respetar la organización de ponencias seguida en el encuentro de Valencia, de tal modo que, en primer lugar, se aborda la biodiversidad que se puede hallar en el medio subterráneo ibero-insular. Desafortunadamente, y por motivos diversos, en esta primera parte algunos grupos importantes no han podido incluirse, como araneidos, quilópodos o diplópodos; también se echa en falta algunos grupos que a pesar de hallarse escasamente representados si poseen unas pocas especies estrictamente dependientes del medio subterráneo, como ácaros, palpígrados o zigentomas, entre otros. Por cuestiones prácticas, los crustáceos de vida acuática con una alta diversidad en el medio subterráneo han sido reunidos bajo un solo epígrafe, con excepción de las batinelas. En segundo lugar, son tratadas las distintas regiones biogeográficas que abarca el territorio hispano-luso, siguiendo con cierta fidelidad la división clásica, propuesta por el Dr. Francesc Español (1969). Por último, y en tercer lugar, son tratados algunos aspectos de la conservación de la biodiversidad y de los espacios subterráneos, con referencia a la problemática en España y Portugal.
- EU needs groundwater ecosystems guidelinesPublication .

However, the proposal foregoes environmental quality standards specifically tailored to sensitive groundwater species and fails to require biomonitoring for groundwater ecosystems. Despite repeated calls for consideration (2, 3) since the first Water Framework Directive in 2000 (4), groundwater ecosystems are at risk of being overlooked yet again.
- Fundamental research questions in subterranean biologyPublication . Mammola, Stefano; Amorim, Isabel R.; Bichuette, Maria E.; Borges, Paulo A. V.; Cheeptham, Naowarat; Cooper, Steven J.

Judson; Zagmajster, Maja; Cardoso, PedroFive decades ago, a landmark paper in Science titled The Cave Environment heralded caves as ideal natural experimental laboratories in which to develop and address general questions in geology, ecology, biogeography, and evolutionary biology. Although the 'caves as laboratory' paradigm has since been advocated by subterranean biologists, there are few examples of studies that successfully translated their results into general principles. The contemporary era of big data, modelling tools, and revolutionary advances in genetics and (meta)genomics provides an opportunity to revisit unresolved questions and challenges, as well as examine promising new avenues of research in subterranean biology. Accordingly, we have developed a roadmap to guide future research endeavours in subterranean biology by adapting a well-established methodology of 'horizon scanning' to identify the highest priority research questions across six subject areas. Based on the expert opinion of 30 scientists from around the globe with complementary expertise and of different academic ages, we assembled an initial list of 258 fundamental questions concentrating on macroecology and microbial ecology, adaptation, evolution, and conservation. Subsequently, through online surveys, 130 subterranean biologists with various backgrounds assisted us in reducing our list to 50 top-priority questions. These research questions are broad in scope and ready to be addressed in the next decade. We believe this exercise will stimulate research towards a deeper understanding of subterranean biology and foster hypothesis-driven studies likely to resonate broadly from the traditional boundaries of this field.
- The subterranean fauna of a biodiversity hotspot region - Portugal: an overview and its conservationPublication . Reboleira, Ana Sofia; Borges, Paulo A. V.; Gonçalves, Fernando; Serrano, Artur R. M.; Oromí, PedroAn 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 to be demonstrated if this fact is still true after investing in standard surveys in cave environments. The major problems related to the conservation of cave fauna are discussed, but it is clear that the protection of this specialized fauna implies an adequate management of surface habitats.
- Temperature variation in caves and its significance for subterranean ecosystemsPublication . Medina, Maria J.; Antić, Dragan; Borges, Paulo A. V.; Borko, Špela; Fišer, Cene; Lauritzen, Stein-Erik; Martín, Jose L.; Oromí, Pedro; Pavlek, Martina; Premate, Ester; Puliafico, Ken P.; Sendra, Alberto; Reboleira, Ana SofiaABSTRACT: Climate change affects all ecosystems, but subterranean ecosystems are repeatedly neglected from political and public agendas. Cave habitats are home to unknown and endangered species, with low trait variability and intrinsic vulnerability to recover from human-induced disturbances. We studied the annual variability and cyclicity of temperatures in caves vis-à-vis surface in different climatic areas. We hypothesize that cave temperatures follow the average temperature pattern at the surface for each location with a slight delay in the signal, but we found three different thermal patterns occurring in caves: (1) high positive correlation and a similar thermal pattern to the surface, (2) low correlation and a slight thermal delay of the signal from the surface, and (3) high negative correlation with an extreme delay from the surface. We found daily thermal cycles in some caves, which may potentially control the circadian rhythms of cave organisms. Our results show that caves had lower thermal amplitude than the surface, and that thermal averages within caves approximately correspond to the to the annual average of surface temperature. Caves buffer external temperature and act as refugia for biota in extreme climatic events. Likewise, temperature increases at surface will lead to increment in caves, threatening subterranean biota and ecosystem services.
