- Description:
- One of the best documented effects of climate change on biodiversity are shifts in phenology. However, long-term data quantifying and projecting the expected changes in phenology associated with climate warming are limited to a few well-recorded areas in the world. In the absence of temporal recording, an alternative approach is to determine the phenological response of species along marked gradients in climate or along latitudinal or altitudinal transects (space-for-time substitution). We studied the phenology (timing and duration of the flight period) of butterflies in 2006 along an altitudinal gradient (900-1680 m; estimated temperature lapse rate = -6.6°C/km) in the Serranía de Cuenca (central Spain) at the assemblage and individual species levels. Timing of the flight period was later for assemblages at high than at low altitudes. A similar trend of an increasing delay in the flight period with altitude was recorded for some individual species. However, there were also some exceptions to this pattern regardless of the number of sites and the altitudinal ranges of the species, suggesting possible local adaptation to regional climate. The duration of the flight period was shorter at high altitudes for assemblages, but this trend was not mirrored in the response of individual species. The results partly support substituting space-for-time when assessing the potential effect of climate change on phenophases such as the timing of the flight period, but we recommend extreme caution in extrapolating the results in the absence of information on how the responses of populations differ. and Juan Ignacio De Arce Crespo, David Gutiérrez.

3. Andalusi sherds from Prague

- Subject:
- Middle Ages, Prague, commerce, Spain, Almohad empire, středověk, Praha, obchod, Španělsko, and almohádské impérium
- Language:
- Czech
- Description:
- Two fragments of lustre-glaze tableware excavated at the Týn merchant inn in the Staré-Město quarter of Prague, the archaeological deposition context of which may be dated into the turn of the 13th and 14th century, represent products of Andalusi pottery workshops of 12th and early 13th centuries. The route by which this tableware service came to Prague is difficult to trace. It seems most logical to link the introduction of this luxury pottery with the wave of Andalusi products, especially precious textiles, supplying the highest circles of Bohemian society roughly between 1250 and 1320. This commercial operation might have followed up the trade ventures of Andalusi-oriented entrepreneurs furnishing customers of western Europe along the Atlantic coast with luxury items originating in Andalusi production plants. An alternative to this idea is represented by the possibility that the vessels came to Prague in the baggage of some of its Jewish residents. and Dva zlomky přepychové stolní keramiky s lustrovou glazurou, nalezené při výzkumu Týnského dvora v Praze v archeologickém kontextu uloženém nejspíše na přelomu 13. a 14. stol., představují výrobky andaluských dílen almohádského období Iberského poloostrova a byly zhotoveny nejspíše ve 12. či raném 13. století. Rekonstruovat cestu tohoto přepychového stolního servisu z Andalusie do Prahy není jednoduché. Nejlogičtější řešení tu představuje myšlenka transportu v důsledku almohádského obchodu se zeměmi západní Evropy podél jejího atlantického pobřeží až do oblasti Severního a Baltského moře. Druhou a stejně dobře představitelnou alternativu představuje přivezení souboru luxusního stolního zboží některým z židovských obyvatel středověké Prahy.

- Subject:
- Chigger mites, Mediterranean, Spain, Africa, bat hosts, Pipistrellus kuhlii, and Plecotus austriacus
- Language:
- English
- Description:
- A sample of chigger mites from bat hosts collected in the Balearic Islands (Western Mediterranean Sea) is found to include two species. These are the first records of bat-infesting chiggers identified to species in Spain. Chiggers collected from Pipistrellus kuhlii (Kuhl) in Menorca are identified as Oudemansidium komareki (Daniel et Dusbábek, 1959); this species, which was known from Austria, Bulgaria, Romania, Slovakia, Moldova, Crimea, and Azerbaijan, is recorded for the first time in Spain. Chiggers collected from Plecotus austriacus (Fischer) in Formentera are identified as Trombicula knighti Radford, 1954, which was insufficiently described from a bat in Yemen and known only from its type locality. We transfer this species to the genus Trisetica Traub et Evans, 1950 and provide its re-description based on paratypes and the material from the Balearic Islands. The species Sasatrombicula (Rudnicula) balcanica Kolebinova, 1966 is synonymised with T. knighti. One species closely related to T. knighti, Trisetica aethiopica (Hirst, 1926), which was recorded in Ghana, Uganda, South Sudan, and Madagascar, is re-described on the basis of its syntype deposited in the Natural History Museum, London, UK. This specimen is designated as lectotype.

- Subject:
- Gadiformes, Lepidion lepidion, Mora moro, and Spain
- Language:
- English
- Description:
- A new capillariid nematode, Capillostrongyloides morae sp. n., is described from specimens collected from the stomach and intestine of the common mora, Mora moro (Risso), and the Mediterranean codling, Lepidion lepidion (Risso) (both Gadiformes, Moridae), off the Mediterranean coasts of Spain. The new species shows similar morphological features as other congeneric species occurring in freshwater and marine fishes, but it differs in the length of the body and spicules, the size of the caudal bursa, and the presence of an elevated anterior vulvar lip. Capillostrongyloides morae sp. n. is the second species within the genus for which the presence of a stylet is reported, and the first one in which this structure along with the distribution of cephalic papillae and oral structures (e.g. lips and lobes) are clearly shown by using scanning electron microscopy.

- Language:
- English
- Description:
- The community composition and structure of helminths of Pipistrellus pipistrellus (Schreber, 1774) from two widely separated Spanish localities, El Saler (n = 42) and the San Pedro pothole (n = 34), were determined and compared. Five species of trematodes, Plagiorchis (Plagiorchis) sp., Lecithodendrium (Lecithodendrium) linstowi Dollfus, 1931, Prosthodendrium (Prosthodendrium) sp., Pycnoporus heteroporus (Dujardin, 1845) and Parabascus semisquamosus (Braun, 1900), and one species of cestode, Hymenolepis pipistrelli López-Neyra, 1941, were found. The two bat populations harboured the same helminth species and showed the same trematode dominance, but the most important differences between the two helminth community structures were attributable to L. (L.) linstowi and H. pipistrelli. The mean species richness in the two localities was not significantly different. The mean number of helminth species per infected bat, mean infracommunity abundance and mean infracommunity diversity showed significant differences between both localities. The number of helminths per bat in both populations displayed an aggregated distribution. Results indicate that the different characteristics of the P. pipistrellus foraging area in both localities are important in determining the composition and structure of helminth communities in this bat species. This is the first study of a Palaearctic bat helminth community.
