“…The distribution of these coastal caves in 'desirable' locations in the tropics often places them at a considerable disadvantage (Iliffe, 2002). Numerous stygobiont species follow patterns of regional and even single-cave endemicity (Sket, 1999;De Grave et al, 2007), making them more prone to be severely impacted and becoming extinct as a result of pollution and habitat destruction. The opportunity to document and study anchialine cave biodiversity and evolution is a fleeting one (Wilson, 1985;Iliffe, 2002) and the potential for substantial discoveries is under threat of rapid decline and eventual disappearance.…”

Abstract:Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats. Here we review previous contributions to our understanding of anchialine biodiversity and evolution, and discuss the potential of "speleogenomic" methods for future research in these threatened systems.

“…The only published information on the freshwater Greek shrimp fauna is focused on zoogeography, taxonomy, morphometry and karyological analysis (Anastasiadou et al 2004(Anastasiadou et al , 2009Anastasiadou & Leonardos 2008, 2010García Muńoz et al 2009;Christodoulou et al 2012), while bionomic studies are lacking at all. But, as it has been recorded in previous studies, the freshwater shrimps play a crucial role in ecosystems, occurring in a variety of habitats (De Grave et al 2008) and transferring energy from lower levels of the trophic chain (detritus, phytoplankton and riparian vegetation) to higher ones (carnivorous fishes) (Meurisse-Genin et al 1985;Fidalgo 1989;García-Berthou & Moreno-Amich 2000;Fidalgo & Gerhardt 2002;Duarte et al 2012). Especially Atyids, apart from filtering out suspended matter (phytoplankton, small zooplankton or organic matter from the water column) by means of the setose mouthparts (Shram 1996), use additionally the feeding chelipeds, which bear characteristic tufts on the tips, for the detritus and microbial film collection (Fryer 1960;De Grave et al 2008).…”

“…Among the macroinvertebrates, the freshwater caridean shrimps account for approximately a quarter of all described Caridea, numerically dominated by the Atyidae and Palaemonidae (De Grave et al 2008). These two major families are represented up today by five species in Greek freshwater ecosystems: the freshwater shrimps Atyaephyra acheronensis Christodoulou et al, 2012, A. stankoi Karaman, 1972, A. strymonensis Christodoulou et al, 2012and A. thyamisensis Christodoulou et al, 2012 and the grass shrimp Palaemonetes antennarius (H. Milne-Edwards, 1837).…”

“…Duarte et al (2012) also emphasize to the feeding plasticity of the family's species, indicating its crucial role in plant litter breakdown in lotic habitats. On the other hand, Palaemonids demonstrate agonistic interactions and predation via enlarged second chelae (De Grave et al 2008). Especially for certain species of the family, such as A. desmarestii, has been reported that demonstrates high adaptability in physicochemical fluctuations and in colonizing new habitats (Cottiglia 1983;Fidalgo 1985Fidalgo , 1989Van den Brink and Van der Velde 1986;Gottstein Matočec & Kerovec 2002;Gottstein Matočec et al 2006 and references herein) and has been proposed as food resource in the aquaculture of freshwater fishes (Fidalgo & Gerhardt 2002).…”

In order to have a comprehensive evaluation and classification of the natural biota of Lake Pamvotis, the present study aims at investigating shrimps' bionomic traits. Information on shrimps' habitat preferences, abundances, and syntopic species in relation to the physicochemical profile of the lake's water are investigated for the first time. The study was carried out on a bi-monthly base, at six littoral sites of the lake. Samples' study from different habitats and seasons revealed that the freshwater shrimp Atyaephyra thyamisensis was the most abundant species, accounting for 44.76% of the total taxa catch, while the grass shrimp Palaemonetes antennarius was less abundant (7.54%). Syntopic fish species in the littoral zone of Lake Pamvotis such as Economidichthys pygmaeus, Gambusia holbrooki, Knipowitschia caucasica and Rutillus panosi showed interannual differences with abundances of 24.12%, 19.13%, 4.26% and 0.20%, respectively. Correspondence analysis revealed clear patterns between species and stations. A. thyamisensis was predominant in shallow, well oxygenated water bodies rich with aquatic vegetation, but it was absent from deeper habitats. P. antennarius was found mainly in lentic water bodies, rocky substratum and deeper habitats. Taking into account the high ecological importance of the freshwater shrimps in ecosystems' energy flow, ecological and biological data of lake's shrimps are discussed and presented thoroughly. Threats and conservation measures for both shrimp species are debated also in detail.

South America is considered a world biodiversity hotspot, especially for freshwater ecosystems where there is significant biodiversity and endemism across different taxonomic groups. Native South American crayfishes are characterized by small range distributions, high levels of endemism and specific habitat requirements. Although this group may be considered one of the most threatened among South American freshwater crustaceans, IUCN Red List assessments for most of these species are ‘data deficient’. IUCN assessments are technical evaluations of species risk of extinction based on biological indicators of population features, thereby providing a ‘conservation status’ for each species based on common and international standards. Attempts to assess the conservation status of native South American crayfishes have been limited mainly owing to a lack of fundamental data and also misinterpretations of present information. Thus, a revision of the state of knowledge of native South American crayfishes (taxonomy, phylogeny and distribution, genetics, ecology and threats) was carried out coupled with IUCN assessments of conservation status. Globally, the lack of information on the biology of these species is still the major obstacle to making reliable conservation status assessments. For this reason, the Data Deficient (DD) category is still appropriate for many species. However, based on the Extent of Occurrence (EOO) and severely fragmented populations, number of locations and decline in area, extent or quality of habitat, it is recommended that some species (especially Virilastacus spp.) should be moved to threatened categories (VU, EN or CR). The data suggest that others are appropriately in the Near Threatened (NT) category, because they almost reach the thresholds for threatened categories. The assessment of conservation status is essential to support future conservation actions, especially for species allocated to threatened categories. This study has identified new species under threat and also areas for future study to provide relevant data for conservation assessment for ‘data deficient’ species.
