The European wild rabbit – Oryctolagus cuniculus – is classified as Near Threatened (NT), which includes near-threatened species. This article presents an analysis of the dynamics of the number of individuals of the studied species in zoos and nurseries belonging to the Eurasian Regional Association of Zoos and Aquariums (EARAZA). The list of cities that have a European wild rabbit in their zoos is given. The sex and age ratio of individuals of the studied species in the interval from 2004 to 2018 is indicated. According to the results of the analysis, a number of arguments are given in favor of the expediency of breeding the European wild rabbit in zoos and nurseries of EARAZA.

In recent decades, the translocation of European wild rabbits (Oryctolagus cuniculus) has been a common strategy used by gamekeepers and conservationists to improve populations with low rabbit abundance. Using a non-spatial, mixed stochastic–deterministic model, we assessed the effects of the timing of restocking of rabbits on the persistence of wild rabbit populations, as well as the effects of extraction on donor populations. Different age-structured restocking strategies and extraction rates were tested. We also assessed the number of restocking batches that a donor population can supply while remaining stable. Our results indicate that the best months to introduce individuals are October–March, with the highest success in January. In contrast, the best timing for extraction is during summer, when the number of individuals is high. Authorities should therefore include the timing and number of rabbits released or captured in their management strategies, especially where these factors have been previously overlooked.

1. Between November 1936 and February 1937, ninety-six rabbits were examined, whilst between August 1937 and July 1938, 446 rabbits were examined for cestode parasites. The rabbits were obtained from the same area.2. The rabbits were infected with the following cestodes to the extent given, for the two periods respectively:3. Two species of the genus Hymenolepis are recorded for the first time from the rabbit, and they are briefly described.4. The seasonal fluctuations in the incidence of the above cestodes are discussed.5. The span of life of both Cittotaenia pectinata and C. denticulata is seen to be not greater than 10 months, and evidence is given to show that the intermediate host of C. denticulata is available between April and December, and that of C. pectinata from August to April.6. Evidence of host and age resistance is demonstrated in Cysticercus pisiformis.

Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller—typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated.

Abstract We report the occurrence of the European otter (Lutra lutra Linnaeus, 1758) along the entire Romanian Black Sea coast, for the first time. Several sightings were within the harbor and the city of Constanţa, indicating that the otter can accommodate to and tolerate high human impact. The report is based on observations made between 2012 and 2015. The species has been previously reported from all Romanian regions but not from the Black Sea coast. The occurrences reported within this article confirm an extension of the range of this Near Threatened species on the Romanian Black Sea coast, most probably due to the increasing of population size from other sources such as the Danube floodplain.

Wildlife plays an important role in the epidemiological cycle of Toxoplasma gondii. The European wild rabbit (Oryctolagus cuniculus) can be a source of infection to wild and domestic hosts, including human beings. Additionally, as an herbivorous animal, the European wild rabbit may also be a sentinel of environmental contamination with T. gondii and, consequently, an indicator of the potential transmission of this parasite. The purpose of the present work was to detect T. gondii DNA in European wild rabbit from central Portugal, as well as the possible implications for public health. Heart and diaphragm samples were obtained from 28 rabbits hunted in central Portugal. Nested PCR separately amplified the 5′ and 3′ ends of the surface antigen 2 (SAG2) gene. T. gondii DNA was detected in 19 out of the 28 sampled animals, resulting in a prevalence of 67.9%. These results show that T. gondii infection occurs in European wild rabbit and therefore may pose a potential risk for humans if consumed as raw or undercooked meat. Measures should be taken in order to prevent infection by this zoonotic parasite and for the conservation of wildlife. To the best of our knowledge, this is the first study performed by means of PCR on T. gondii in European wild rabbit meat samples.
