Abstract A description is provided for Hilberina foliicola, which is apparently saprobic and able to colonize a diverse range of plants. Some information on its habitats, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (North America USA Virginia Europe UK) and hosts (including Fagus sylvatica and Quercus sp.). No reports of negative economic impacts have been found.

The original description of Elapomorphus wuchereri Günther, 1861 included a drawing and brief comments about the morphology of three specimens; two of the latter belong to another species and the holotype is lost. Based on the discovery of new specimens, we redescribe Elapomorphus wuchereri and designate a neotype. We discuss the variation and the taxonomic history of the species, and based on the results of a species distribution model analysis (SDM), we describe the distribution, extent of occurrence, and conservation status.

Occurrence Records

A species’ distribution provides fundamental information on: climatic niche, biogeography, and conservation status. Species distribution models often use occurrence records from biodiversity databases, subject to spatial and taxonomic biases. Deficiencies in occurrence data can lead to incomplete species distribution estimates. We can incorporate other data sources to supplement occurrence datasets. The general public is creating (via GPS-enabled cameras to photograph wildlife) incidental occurrence records that may present an opportunity to improve species distribution models. We investigated (1) occurrence data of a cryptic group of animals: non-marine snakes, in a biodiversity database (Global Biodiversity Information Facility (GBIF)) and determined (2) whether incidental occurrence records extracted from geo-tagged social media images (Flickr) could improve distribution models for 18 tropical snake species. We provide R code to search for and extract data from images using Flickr’s API. We show the biodiversity database’s 302,386 records disproportionately originate from North America, Europe and Oceania (250,063, 82.7%), with substantial gaps in tropical areas that host the highest snake diversity. North America, Europe and Oceania averaged several hundred records per species; whereas Asia, Africa and South America averaged less than 35 per species. Occurrence density showed similar patterns; Asia, Africa and South America have roughly ten-fold fewer records per 100 km2than other regions. Social media provided 44,687 potential records. However, including them in distribution models only marginally impacted niche estimations; niche overlap indices were consistently over 0.9. Similarly, we show negligible differences in Maxent model performance between models trained using GBIF-only and Flickr-supplemented datasets. Model performance appeared dependent on species, rather than number of occurrences or training dataset. We suggest that for tropical snakes, accessible social media currently fails to deliver appreciable benefits for estimating species distributions; but due to the variation between species and the rapid growth in social media data, may still be worth considering in future contexts.

Freshwater Crabs

Abstract The present status of freshwater crabs (Decapoda, Brachyura) in Turkey is reviewed in this study, with the purpose of identifying the exact number of species, their conservation status, and their distribution. In previous records, it was reported that Turkey has nine freshwater crab species belonging to the genus Potamon: Potamon bileki Pretzmann, 1971, P. ibericum (Bieberstein, 1809), P. hueceste Pretzmann, 1962, P. persicum Pretzmann, 1962, P. magnum Pretzmann, 1962, P. potamios (Olivier, 1804), P. setiger Rathbun, 1904, P. rhodium Parisi, 1913, and P. mesopotamicum Brandis, Storch & Türkay, 1998. However, there was no detailed information on species distribution in Turkey. This review is intended to update the distribution of species in the country, and it revealed that populations of three more freshwater crab species (P. karpathos, P. fluviatile and P. hippocrate) also occur; thus, there are currently 12 freshwater crab species in Turkey. In addition, this review provides a distribution map and identifies possible threats to each species. This review can serve decision makers in the development of management strategies to better protect the environments of these species that are facing growing anthropogenic impacts.

Surveys dedicated to better describing the distribution of Uma scoparia in Arizona are reported. These extend this species’ distribution in La Paz County, Arizona, 20 km further to the south than previously described. Six records on the outside of a confused range are presented alongside data from 170 captures within this range. This species is well known from California but its Arizona distribution is little understood and less well studied than other members of its genus. Concern about the conservation status of the disjunct Arizona population makes this report valuable to resource managers. Lizards were observed with ease and in large numbers at nearly all sites surveyed.

Source Of Information

Museu Paraense Emilio Goeldi (MPEG), situated at Brazilian state of Pará, houses the third largest South-American mammal scientific collection, being a primary source of information for the study of Amazonian and Neotropical mammalians. The collection holds 245 felid specimens, comprising 210 skulls, 53 skins, 10 skeletons, and two anatomical pieces, representing 90% of wild Brazilian cat species, mainly from localities of Northern Brazil. We presented a list of this material, indexed by the genera and species. We also provided craniodental measurements of all the specimens with skull, and comment on the conservation status of the species and other remarkable data, including the first record of Leopardus tigrinus in the Brazilian state of Rondônia.
