“…In these cases it seems that native crayfish disappears after several years (Bubb et al, 2005). On the other hand, mixed red swamp and signal crayfish populations, also becoming more and more frequent, can only be expected in the lower reaches and sparingly, as they usually come into contact in central Spain under 1000 m a.s.l., since red swamp crayfish is rarely found above this elevation, except in some reservoirs and still waters (Alonso et al, 2000).…”

“…Although height is the factor that explains the distribution of native crayfish in the area better, as in other parts of Spain (Gil and Alba-Tercedor, 2002;, it probably encompasses the effects of several correlated variables, not only physical, such as water temperature, width, habitat structure and hydrology, but also trophic ones. While in other European countries the A. pallipes complex is also present in lowlands (Troschel and Dehus, 1993;Füreder et al, 2002), its preference for higher reaches seems to be the rule in Spain (Diéguez et al, 1997;Alonso et al, 2000;Gil and Alba-Tercedor, 2002;Martínez et al, 2003). Nonetheless, they select slower flow macrohabitats, such as pools and glides within these higher slope stretches.…”

“…One of the first Spanish wild signal crayfish populations developed as early as the 1980s close to this area, but no natural or human-led dispersal was observed for twenty years, while fishing for signal crayfish was forbidden all over Spain. But since it was allowed in neighbouring territories a wave of illegal introductions have started, and more than thirty new populations have being detected in the vicinity during the last decade, highlighting the role that expectation of future fishing can play in the dispersal of invasive crayfish (Alonso et al, 2000), which is still going on. We did not find white-clawed crayfish and signal crayfish living together.…”

“…It was present in all the main hydrographic basins (Alonso et al, 2000), chiefly distributed over the limestone country which dominates Eastern Spain. It was less abundant in or absent from the acidic watersheds, which could not provide enough calcium for a proper moulting process (Jussila et al, 1995), and also from arid areas and the highest mountain ranges.…”

“…It was less abundant in or absent from the acidic watersheds, which could not provide enough calcium for a proper moulting process (Jussila et al, 1995), and also from arid areas and the highest mountain ranges. Until the end of the 20th century, the A. pallipes species complex provided an important source of both income and sport for local people, as shown by catch data and license numbers (Torre and Rodríguez, 1964;Alonso et al, 2000). Since then, increasing habitat degradation caused by physical disturbance, drainage and sewage has led to its decline, speeded up later by the spread of non-indigenous species transmitting aphanomycosis (Diéguez-Uribeondo et al, 1997;Diéguez-Uribeondo, 2006;Haffner et al, 2006).…”

Key-words: Austropotamobius pallipes, distribution, habitat, managementAlto Tajo Natural Park is a protected area in Central Spain. Mainly welldrained limestone country, this area has traditionally held abundant whiteclawed crayfish populations. Nevertheless, its occurrence has decreased during the last few decades because of different factors. To address the scarce information on the species, an extensive survey including habitat characterisation was carried out during the summer of 2008, sampling 116 water bodies. Using a combination of survey techniques, a total of 23 populations in different degrees of conservation was found. Crayfish mainly inhabited headwater stretches less than 1 km in length, together with small ponds. A significant proportion of these populations could be related to previous stocking events. The present study revealed a high degree of isolation, with populations showing a fragmented distribution pattern. The information obtained might be used to discriminate the most adequate localities for future stocking actions, hopefully improving the success of this management tool. RÉSUMÉDes facteurs liés à la présence du complexe spécifique Austropotamobius pallipes (Lereboullet, 1858) en rivières calcaires de montagne du centre de l'Espagne Mots-clés : Austropotamobius pallipes, distribution, habitat, gestionLe parc naturel Alto Tajo est un site protégé situé au centre de l'Espagne. Au caractère notamment calcaire, cette zone a hébergé traditionnellement d'abondantes populations d'écrevisses ibériques. Pourtant, sa présence a été réduite pendant les dernières décades à cause de différents facteurs. Pour pallier ce manque d'information sur les espèces, on a réalisé une étude exhaustive de 116 masses d'eau pendant l'été 2008, y compris une caractérisation d'habitat. En utilisant une combinaison de méthodes de suivi, on a trouvé 23 populations en différents états de conservation. Les écrevisses occupant les têtes de bassin versant sur des tronçons de moins de 1 km ainsi que de petits étangs. Une proportion significative de ces populations serait issue de précédents repeuplements. Cette étude a prouvé un haut niveau d'isolement des populations qui montrent un modèle de distribution fragmentée. Ces résultats serviront à discriminer les points les plus appropriés pour les futurs repeuplements envisageant une amélioration de l'efficacité de cet outil de gestion.

1. A study on the genetic variability of the white-clawed crayfish was carried out based on mitochondrial cytochrome oxidase subunit I gene sequences. The sequences applied were more informative regarding white-clawed crayfish genetic variability than others previously used.2. Two haplotypes were found to exist in the Iberian Peninsula. The haplotypes exhibit a strong geographic subdivision (F ST ¼ 0:83). One of the Iberian haplotypes was similar to north Italian haplotypes and the second differed in only one mutation. This pattern of genetic variability contrasts with those found in glacial refugial areas of France, Italy and the Balkan Peninsula.3. Two hypotheses on the origin of the white-clawed crayfish in the Iberian Peninsula are discussed: (i) one based on an anthropogenic origin, and (ii) a second based on a successive number of postglacial ancient and recent bottlenecks, i.e. the disjunction between Iberian and Italian populations of white-clawed crayfish species is due to competition between A. italicus and A. pallipes, in addition to the impact of crayfish plague and human translocations.4. New references for the white-clawed crayfish in the Iberian Peninsula were found in medieval and Arabic texts. The results show that this species has been thriving in this peninsula since ancient periods and that its indigenous status should not be questioned.5. Conservation action and plans should consider the low genetic diversity as a limitation for farmraising specimens more adapted and resistant to changing environments and diseases.

ABSTRACT1. Spanish populations of the white-clawed crayfish have declined sharply over the last three decades. Although Austropotamobius pallipes was once widely distributed and very abundant in most of the limestone basins of the country, outbreaks of crayfish plague since 1978 have reduced its populations, and now only some 500-600 small populations are left.2. Consequently, the species now enjoys protection under national legislation. Management decisions regarding the conservation of a threatened species require an understanding of the genetic structure of its populations.3. Using random amplified polymorphic DNA (RAPD) fingerprinting the genetic variability of 11 populations of A. pallipes was assessed over the species' range in Spain, and their phylogenetic relationships determined.4. Substantial genetic differentiation was detected among the populations tested; no clear relationship was found between patterns of genetic variability and hydrological basin. The RAPD markers showed the degree of genetic variability of these populations to be similar to, and in some cases slightly higher than, that reported in previous studies on other Spanish and European populations of A. pallipes.5. The results offer hope for the recovery of this species in Spain, and provide information that might be useful in the management of crayfish reintroduction programmes.
