    On the occurrence of Varanus nebulosus (Gray, 1831) (Squamata: Varanidae) on Riau Archipelago, Indonesia

    Zootaxa 3919(1) 197.

    The occurrence of Varanus nebulosus (Gray, 1831) on Sumatra still remains open for debates, while records are limited, especially those associated with a voucher specimen. The oldest record of V. nebulosus that is associated with a specimen, i.e. SMF 11554 is dated back to 1889 and presumably from Bengal (“Bengalen”), which now lies around Bangladesh. The specimen is kept at Senckenberg Museum Frankfurt (SMF) in Germany. We collected specimens from two islands in the Riau Archipelago, just west of Sumatra and provided new distribution data for this protected species of Monitor lizard in...

    Flora Montiberica 59 29-33.

    Rumex vesicarius L. (Polygonaceae), neophyte for the Valen- cian Flora (Spain, Western Mediterranean) . A neophyte for the Valencian flora, Bladder dock ( Rumex vesicarius , L.), is reported. The species was found at lowlands in the surroundings of Sagunto (Valencia), cl ose to the Mediterranean Sea. Plants formed a single population with 131 individua ls occupying 4.7 ha. A brief descrip- tion of the species is given and its genera l distribution and around the Mediterranean are reviewed, emphasizing its invasive potential.

    Predictive spatial niche and biodiversity hotspot models for small mammal communities in Alaska: applying machine-learning to conservation planning

    Landscape Ecology.

    Context Changing global environmental conditions, especially at northern latitudes, are threatening to shift species distributions and alter wildlife communities. Objective We aimed to establish current distributions and community arrangements of small mammals to provide important baselines for monitoring and conserving biodiversity into the future. Methods We used 4,408 archived museum and open-access records and the machine learning algorithm, RandomForests, to create high-resolution spatial niche models for 17 species of rodents and shrews in Alaska. Models were validated using independent...

    Climate as a driver of tropical insular diversity: comparative phylogeography of two ecologically distinctive frogs in Puerto Rico

    Ecography n/a-n/a.

    The effects of late Quaternary climate on distributions and evolutionary dynamics of insular species are poorly understood in most tropical archipelagoes. We used ecological niche models under past and current climate to derive hypotheses regarding how stable climatic conditions shaped genetic diversity in two ecologically distinctive frogs in Puerto Rico. Whereas the mountain coquí Eleutherodactylus portoricensis is restricted to montane forest in the Cayey and Luquillo Mountains, the red-eyed coquí E. antillensis is a habitat generalist distributed across the entire Puerto Rican Bank (...

    The not-so-Irish spurge: Euphorbia hyberna (Euphorbiaceae) and the Littletonian plant ‘steeplechase’

    Biological Journal of the Linnean Society 114(2) 249-259.

    The disjunct distributions of the Lusitanian flora, which are found only in south-west Ireland and northern Iberia, and are generally absent from intervening regions, have been of great interest to biogeographers. There has been much debate as to whether Irish populations represent relicts that survived the Last Glacial Maximum (LGM; approximately 21 kya), or whether they recolonized from southern refugia subsequent to the retreat of the ice and, if so, whether this occurred directly (i.e. the result of long distance dispersal) or successively (i.e. in the manner of a ‘steeplechase’, with the...

    Proceedings of the 8th CMAPSEEC 51-58.

    Genetic diversity and geographic distribution for 403 geo-referenced observations of ex situ medicinal plants collection data including 13 species, from twelve counties of Albania was investigated, using grids of 10 x 10 km cells to assess the number of observations per species and per district, the area of occupancy, the diversity indices and richness estimators. Geospatial analysis detects areas of high (alpha) diversity. Combination of study results for Simpson index, Dominance, Shannon-Weiner, Margalef, Brillouin, species richness and evenness, Equitability, Menhinick, Berger-Parker, and...

    New insights on postglacial colonization in western Europe: the phylogeography of the Leisler's bat (Nyctalus leisleri).

    Proceedings. Biological sciences / The Royal Society 282(1804) 20142605-.

    Despite recent advances in the understanding of the interplay between a dynamic physical environment and phylogeography in Europe, the origins of contemporary Irish biota remain uncertain. Current thinking is that Ireland was colonized post-glacially from southern European refugia, following the end of the last glacial maximum (LGM), some 20 000 years BP. The Leisler's bat (Nyctalus leisleri), one of the few native Irish mammal species, is widely distributed throughout Europe but, with the exception of Ireland, is generally rare and considered vulnerable. We investigate the origins and...

    Impact of habitat loss on distributions of terrestrial vertebrates in a high-biodiversity region in Mexico

    Biological Conservation 184 59-65.

    Mexico is considered a country of biological megadiversity because of its exceptional species richness and endemism. However, much of Mexico’s biodiversity is under threat due to a variety of factors, in particular, habitat loss. The Mexican legal standard (Norma Oficial Mexicana; NOM-ECOL-059-2010) uses four criteria to analyze specieś extinction risk at a national scale. However, when prioritizing areas for biodiversity conservation it is also important to incorporate knowledge of the conservation status of species at a more localized scale (regional, state, or municipal levels) for...

    Morphological and molecular evidence supports recognition of Danaus petilia (Stoll, 1790) (Lepidoptera: Nymphalidae) as a species distinct from D. chrysippus (Linnaeus, 1758)

    Systematics and Biodiversity 1-17.

    The danaine butterfly Danaus chrysippus (Linnaeus, 1758) occurs widely in the Afrotropical, Oriental and Australian regions and comprises a taxonomic complex, with recent authors recognizing between one and three species. Danaus petilia (Stoll, 1790) has previously been considered to be a subspecies of D. chrysippus, but we present evidence from wing colour pattern, morphological characters and molecular data that support a recent proposal to treat D. petilia as a separate, parapatric species. The subspecies D. chrysippus cratippus (C. Felder 1860) has a limited range in Indonesia, and was...

    Space to invade? Comparative range infilling and potential range of invasive and native plants

    Global Ecology and Biogeography n/a-n/a.

    Aim Our understanding of potential ranges for native and non-native species is often based on their current geographic distributions. Non-native species have had less time than co-occurring native species to expand their ranges following introduction, so non-native ranges may under-represent suitable conditions. Therefore it is often assumed that species distribution models will predict disproportionately smaller potential ranges for non-natives than natives. We compare the distributions of native, endemic, alien and invasive plants to determine how the different range attributes of these...
