Highly Disjunct And Highly Infected Millipedes – A New Cave-Dwelling Species Of Chiraziulus (Diplopoda: Spirostreptida: Cambalidae) From Iran And Notes On Laboulbeniales Ectoparasites, Ana Reboleira, Mohamad Malek Hosseini, Saber Sadeghi, Henrik Enghoff
Ana Sofia P.S. Reboleira
Chiraziulus is a highly disjunct, hitherto monotypic genus of cambalid millipedes, geographically isolated in Iran by more than 7000 km from its presumed closest relatives in East Asia and North America. Recent fieldwork in caves of Iran has provided several specimens of this genus, allowing the description of Chiraziulus troglopersicus sp. nov. The intraspecific variability of the type species, C. kaiseri Mauriès, 1983, is illustrated with scanning electron micrographs. Chiraziulus is characterized by exceedingly long microtrichose gonopod flagella which from their insertion points on the posterior face of the anterior gonopod coxites first point distad instead of basad or basad-posteriad …

Hypogenic Versus Epigenic Subterranean Ecosystem: Lessons From Eastern Iberian Peninsula, Alberto Sendra, Policarp Garay, Vicente Ortuño, Jose Gilgado, Santiago Teruel, Ana Reboleira
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 …

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 …

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
Ana Sofia P.S. Reboleira
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 …
