For instance, the common redstart is a bird species breeding in the lowlands, whereas the black redstart is native to higher altitudes. Some species such as common swift and kestrel, which are originally adapted to enduring in rocky areas, even found a secondary habitat in the house facades and street canyons of towns and big cities. Classic rock dwellers include peregrine, eagle owl, rockthrush, snowfinch and alpine swift. The presentation focuses on the biology, causes of threat as well as conservation measures taken by the national park concerning the species golden eagle, wallcreeper, crag martin and ptarmigan. Birds breeding in the rocks might not be that high in number, but their survival is all the more fascinating and worth protecting as such!

List of Animal Species with Ranks October 2017
Washington Natural Heritage Program List of Animal Species with Ranks October 2017 The following list of animals known from Washington is complete for resident and transient vertebrates and several groups of invertebrates, including odonates, branchipods, tiger beetles, butterflies, gastropods, freshwater bivalves and bumble bees. Some species from other groups are included, especially where there are conservation concerns. Among these are the Palouse giant earthworm, a few moths and some of our mayflies and grasshoppers. Currently 857 vertebrate and 1,100 invertebrate taxa are included. Conservation status, in the form of range-wide, national and state ranks are assigned to each taxon. Information on species range and distribution, number of individuals, population trends and threats is collected into a ranking form, analyzed, and used to assign ranks. Ranks are updated periodically, as new information is collected. We welcome new information for any species on our list.

Examinationof this material provided such interesting results, that four more collecting trips were made, viz. in April 1990, October 1991, October 1992, and January 1993, in order to collect additional material. Some further research material was provided by a number of colleagues. Since the description of the two nominal taxa Bulimus olivaceus and B. cretensis by L. Pfeiffer (1846), there has always been disagreement in the literature about the tax- onomic status of the Cretan Mastus taxa. Most often only a single species, M. cretensis, was accepted as valid and M. olivaceus was considered a variety or at best a subspecies of it. Heller (1976) was the first to consider M. cretensis and M. -
Species Fact Sheet with Juga Hemphilli Hemphilli
SPECIES FACT SHEET Scientific Name: Juga hemphilli hemphilli (Henderson 1935) Common Name: barren juga Phylum: Mollusca Class: Gastropoda Order: Neotaenioglossa Family: Semisulcospiridae Taxonomic Note: Past genetic analysis by Lee et al. (2006) based on incorrectly identified museum voucher specimens suggested reassignment of the related subspecies Juga hemphilli dallesensis (and therefore the Juga hemphilli conspecifics, including Juga hemphilli hemphilli) to the genus Elimia. However, Foighil et al. (2009) conducted an additional analysis and determined that Juga hemphilli is indeed most closely related to other western Juga and should not be reassigned to the genus Elimia. Turgeon et al. (1998) do not recognize any subspecies of Juga hemphilli. Conservation Status: Global Status: G2T1 (May 2009) National Status: United States (N1) (June 2000) State Statuses: Oregon (S1), Wahington (S1) (NatureServe 2015) IUCN Red List: NE – Not evaluated Technical Description: This subspecies was originally described as Goniobasis hemphilli hemphilli (Henderson 1935). Burch (1982; 1989) revised this subspecies to the genus Juga to reflect the distribution of taxa west of the Continental Divide. Adult: Juga is a genus of medium-sized, aquatic, gilled snails traditionally treated as part of the subfamily Semisulcospirinae within the Pleuroceridae family, although the Semisulcospirinae subfamily was recently elevated to family level based on morphological and molecular evidence (Strong and Köhler 2009). The Pleuroceridae and Semisulcospiridae families both differ from the Hydrobiidae family in that the males lack a verge (male copulatory organ). The genus Juga is distinct from related pleurocerid snails based on reproductive anatomy and egg mass characters (Taylor 1966), as well as features of the ovipositor pore, radula, midgut, kidney, and pallial gonoduct (Strong and Frest 2007). -

W 2015 roku gatunek stwierdzono na 13 stanowiskach na odcinku ok. 100 km pomiędzy Zdunami a Gnieznem. Niewielki udział dogodnych siedlisk naturalnych w otoczeniu linii wskazuje, że występowanie gatunku na przy- torzach jest prawdopodobnie efektem zawleczenia wraz z materiałami budowlanymi.

Müller, 1774) localised in anthropogenic habitats on embankments and in excavations along the Oleś- nica – Gniezno railway (Wielkopolska). In 2015 the species was found in 13 localities on a 100 km long section of the railway between Zduny and Gniezno. As natural habitats of the species in the sur- roundings are scarce, it is probable that the snails were introduced to the sites with building materials. Open, dry, insulated grasslands along tracks are suitable alternative habitats for this endangered snail species.

KRAMARENKO Mykolaiv National Agrarian University, Paryzka Komuna St. 9, Mykolaiv, 54020, Ukraine (e-mail: [email protected]) ABSTRACT: Mechanisms which govern patterns of intra-specific vatiation in land snails were traced within areas of different size, using Brephulopsis cylindrica (Menke), Chondrula tridens (O. F. Müller), Xeropicta derbentina (Krynicki), X. krynickii (Krynicki), Cepaea vindobonensis (Férussac) and Helix albescens Rossmässler as examples. Morphometric shell variation, colour and banding pattern polymorphism as well as genetic polymorphism (allozymes and RAPD markers) were studied. The results and literature data were analysed in an attempt to link patterns to processes, with the following conclusions. Formation of patterns of intra- specific variation (initial processes of microevolution) takes different course at three different spatial scales. At micro-geographical scale the dominant role is played by eco-demographic characteristics of the species in the context of fluctuating environmental factors. At meso-geographical scale a special part is played by stochastic population-genetic processes. At macro-geographical scale more or less distinct clinal patterns are associated with basic macroclimatic -
Aquatic Snails of the Snake and Green River Basins of Wyoming

D. Andersen. 2018. Aquatic snails of the Snake and Green River Basins of Wyoming. Report prepared by the Wyoming Natural Diversity Database for the Wyoming Fish and Wildlife Department. 1 Abstract Freshwater snails are a diverse group of mollusks that live in a variety of aquatic ecosystems. Many snail species are of conservation concern around the globe. About 37-39 species of aquatic snails likely live in Wyoming. The current study surveyed the Snake and Green River basins in Wyoming and identified 22 species and possibly discovered a new operculate snail. We surveyed streams, wetlands, lakes and springs throughout the basins at randomly selected locations. We measured habitat characteristics and basic water quality at each site. Snails were usually most abundant in ecosystems with higher standing stocks of algae, on solid substrate (e.g., wood or aquatic vegetation) and in habitats with slower water velocity (e.g., backwater and margins of streams). We created an aquatic snail key for identifying species in Wyoming. The key is a work in progress that will be continually updated to reflect changes in taxonomy and new knowledge. We hope the snail key will be used throughout the state to unify snail identification and create better data on Wyoming snails.
