Sinaloa possesses a rich biota with unique characteristics due to its proximity to the northern deserts, the tropical lowlands of the south, and the temperate environments of the western slopes of the Sierra Madre Occidental in Mexico. However, threats to its environment makes understanding the biological diversity of Sinaloa crucial. A checklist of the amphibians and reptiles has been generated, and the conservation status of Sinaloa’s herpetofauna summarized with the aim of understanding the potential conservation or management needs. Sinaloa has 159 species of amphibians and reptiles, including 39 species of amphibians and 120 species of reptiles. The herpetofauna of Sinaloa has relatively few species of conservation concern at a global and national scale (IUCN and SEMARNAT lists), but Environmental Vulnerability Scores suggest that there might be greater conservation concerns for the Sinaloa herpetofauna. Families of particular conservation concern include Craugastoridae, Eleutherodactylidae, Ambystomatidae, Crocodylidae, Dactyloidae, Eublepharidae, Helodermatidae, Iguanidae, Phrynosomatidae, Phyllodactylidae, Colubridae, Natricidae, Viperidae, Cheloniidae, and Dermochelyidae.

Pygmy Rabbits

Abstract The pygmy rabbit Brachylagus idahoensis is a sagebrush-obligate species of conservation concern that occurs in the Great Basin and adjacent intermountain areas in the western United States. The species is not known to occur in Colorado, despite proximity to existing populations of pygmy rabbits in Wyoming. We provide the first documentation of the pygmy rabbit in Colorado. Fecal pellets diagnostic of pygmy rabbits were collected in the Vermillion Bluffs area of northwestern Colorado. Samples from 16 pellet clusters were collected for species identification via genetic analyses, and we were able to extract and amplify sufficient DNA from 7 of 16 pellet samples. All seven samples were identified as originating from pygmy rabbits based on a species-specific mitochondrial DNA fragment analysis test. To verify species identification, we also sequenced 225 base pairs of the mitochondrial DNA cytochrome b region from all seven pellet samples. Presence of pygmy rabbits was confirmed from three locations separated by 2.4–7.7 km and pellets represented both adult and juvenile rabbits. Based on the sparseness of burrows in the area, density of pygmy rabbits in the area likely is low; however, systematic surveys by trained observers are needed to delineate the range and density of this species in Colorado. Given the conservation concern for pygmy rabbits across their current range, the newly confirmed presence of this species suggests that assessment of their conservation status in Colorado is warranted.

Epitypes are proposed for two species of Hechtia: H. subalata and H. jaliscana, both endemic to Western Mexico. The holotypes of both species consist of fruiting specimens. While the female flowers of both species are extremely similar, the staminate ones are noticeable different: we select staminate vouchers as epitypes to clearly circumscribe both taxa. As a result of the delimitation of the concept Hechtia subalata and its geographical distribution, we identify a new species from Durango, Mexico, previously misidentified as Hechtia subalata: Hechtia marthae. We provide images portraying plant parts of all species, as well as photographs in habitat. Finally, assessments of the conservation status of the three species sensu IUCN criteria are included.

Five Hawaiian species of Paratachys Casey are revised, including four newly described: Paratachys terryli from Kauai; P. perkinsi from Moloka‘i; P. haleakalae from Maui; and P. aaa from Hawai‘i Island. A lectotype is designated for the fifth Hawaiian species currently combined with Paratachys, Tachys arcanicola Blackburn, 1878 of Oahu. Hawaiian Paratachys spp. known from more than one specimen exhibit some degree of ocular polymorphism, that variation being extreme in P. terryli where individuals range in ocular development from macrophthalmic with broadly convex eyes to microphthalmic with small, flat eyes. All Hawaiian Paratachys species comprise individuals with vestigial wings, with the exception of P. terryli, where a single macropterous, macrophthalmic female complements the other 18 brachypterous specimens. Based on a transformation series of characters from the male aedeagus, the biogeographic history of Hawaiian Paratachys is consistent with progressive colonization of the Hawaiian Island chain. Three of the species do not appear to represent species of conservation concern, with P. terryli and P. haleakalae known from terrestrial deep soil, litter, and streamside microhabitats in montane wet rain forest, and the troglobitic P. aaa occupying the dark zone of numerous, recently developed lava tube caves within the Mauna Loa and Kilauea volcanic massifs. The conservation status of the other two species is much more dire, with P. arcanicola of O‘ahu not seen in nature since the early 20th Century, and P. perkinsi known only from a single specimen fortuitously collected in 1894 near sea level on Moloka‘i.

The Hutě Nature Reserve is located in the central eastern part of the White Carpathians PLA, near the Žítková village. The reserve protects a preserved and topographically heterogeneous area composed of forest groves, meadows, pastures, and spring fens with a high diversity of submontane and thermophilic plant and animal assemblages. The species composition of molluscs (9 out of 10 ecological groups represented) consists mainly of woodland dwellers, which account for the majority of species diversity (30 spp.; 52%), followed by ubiquitous (9; 16%), hygrophilous (5; 9%), hygrophilous woodland dwellers (4; 7%), aquatic (4; 7%) and open-habitat dwellers (3; 5%). Vertigo moulinsiana (EN), internationally protected under Annex II of the EU Habitats Directive, Daudebardia brevipes (VU), Ambigolimax nyctelius (NT), Orcula dolium (NT) and Bythinella austriaca (NT) are species of conservation concern. To retain favourable habitat conservation status, the spring fens with V. moulinsiana occurrence must be managed extensively by grazing or mowing, while the forests must remain in a non-intervention regime.

Abstract Cottus gobio is considered a fish species of conservation concern within the Vişeu Watershed. The habitats state, usually populated by Cottus gobio within the Maramureş Mountains Nature Park (Vişeu and Bistriţa Aurie watersheds) vary among reduced (34.42%), average (45.91%), and good (19.67%). The excellent conservation status is currently missing for populations of this fish in the Vișeu Basin. Human impact categories were inventoried as inducing the diminishment of Cottus gobio habitats and populations in the researched area in comparison with its natural potential are: minor riverbed morphodynamic changes, liquid and solid natural flow disruption, destruction of riparian tree and shrub vegetation, habitat fragmentation-fish populations isolation, organic/mining pollution activities, fish washing away at floods, and poaching.

In 2015, the Strait of Sicily, which includes several banks, was candidate as a future Specially Protected Area of Mediterranean Importance (SPAMI) by the Contracting Parties of the Barcelona Convention. In this context, the present study aims to provide the first biological and ecological characterisation of this poorly known area, focusing on habitats and species of conservation concern. Surveys were carried through a remotely operated vehicle (ROV) and allowed the identification of 19 habitat types, mostly considered of priority interest by the SPA/BD Protocol of the Barcelona Convention. A total of 269 taxa were also identified, mostly Porifera, Cnidaria and Pisces, among which 115 species are of conservation concern according to the International Union for Conservation of Nature (IUCN) Red Lists, the Habitats Directive, the Bern Convention, the SPA/BD Protocol and CITES. ROV surveys allowed some interesting observations on poorly known species and habitats. Results underlined that remarkable discrepancies in species conservation status assessment that exist between the several lists of protected species considered. The IUCN Red Lists, although not legally binding for European States, are the most complete, but, in spite of this, the conservation policies in the EU are largely focused on the Habitats Directive, which is really not exhaustive. An exhaustive and legally binding instrument to protect species of conservation concern at European scale is highly recommended. Acquired results could be useful for the delimitation of a future SPAMI or a network of Marine Protected Areas (including the investigated banks) and the identification of zones within them suitable for different area-based management measures.

Abstract Background White-nose Syndrome (WNS) has reduced the abundance of many bat species within the United States’ Mid-Atlantic region. To determine changes within the National Park Service National Capital Region (NCR) bat communities, we surveyed the area with mist netting and active acoustic sampling (2016–2018) and compared findings to pre-WNS (2003–2004) data. Results The results indicated the continued presence of the threatened Myotis septentrionalis (Northern Long-eared bat) and species of conservation concern, including Perimyotis subflavus (Tri-colored bat), Myotis leibii (Eastern Small-footed bat) and Myotis lucifugus (Little Brown bat). However, we documented a significant reduction in the abundance and distribution of M. lucifugus and P. subflavus, a decrease in the distribution of M. septentrionalis, and an increase in the abundance of Eptesicus fuscus (Big Brown bat). Conclusions Documented post-WNS M. septentrionalis recruitment suggests that portions of the NCR may be important bat conservation areas. Decreases in distribution and abundance of P. subflavus and M. lucifugus indicate probable extirpation from many previously occupied portions of the region.
