Study on bird species diversity, distribution and relative abundance is important for conservation efforts in local and national scale. However, bird diversity, distribution and relative abundance are little known in Karamjal Forest Station, Sundarbans. Ecological appraisal of bird species diversity, distribution and relative abundance of the avifauna of the Karamjal Forest Station were conducted from June 2015 to April 2016. A total of 156 bird species was recorded during the study period. Of which, one was globally Critically Endangered, Gyps bengalensis and two were Near Threatened i.e., Gyps himalayensis and Lusciniapectardens. The distribution of bird among habitat type was significantly different (f =22.069, p<0.05, df = 2). Walking trail was inhabited the highest species diversity (H’= 3.77) with the highest evenness (J=0.823) while water body was recorded the lowest species diversity (H’= 2.93) with the lowest evenness (J=0.804), it could have a relation to the availability of food items in the habitat. This study showed that despite huge tourist pressures this forest station harbour diverse avian species and thus this area should be managed in order to enhance the population of avian species.

This meta-analysis focused on the drift in ichthyodiversity of the Chalan Beel, a marshy, natural inland indentation, the largest of its kind in northwest (NW) Bangladesh. To apprehend the objective, we considered peer-reviewed fish inventories of the area published since 1971. The first checklist on the fishes of the Chalan Beel was compiled in 2009 after which, till now, we found only four similar studies. In total, we found 139 species annotated in these works including 10 exotic species. We, however, surmised a downward trend in fish fauna; from 114 species listed in 2009, in 2017 the Chalan Beel is reported to have 66 species – comprising only 30 species common in each of the five works. Cyprinidae is turned out as the most diverse abundant family for the area with 43 species. The most diverse order, on the contrary, is Siluriformes represented by 10 families and 42 species. Of the fish inventory, 3 were Critically Endangered, 15 Endangered, 13 Vulnerable and 21 Near Threatened in Bangladesh. The Chalan Beel is reported to have 3 globally Vulnerable and 10 globally Near Threatened fish. Reviewing works on the Chalan Beel revealed a potential new exotic species Trichogaster labiosa for Bangladesh and mentioning of 3 species found in no national fish inventories viz., Erethistoides infuscatus, Parachiloglanis hodgarti and Poropuntius clavatus.ECOPRINT 24: 37-46, 2017

The distribution of the three Italian species of Rhysodidae was reviewed by re-examining published data, museum conserved and newly collected specimens. Rhysodes sulcatus chronogeonemy encloses a large majority of old findings and only two recently confirmed active populations are recorded after the year 2000. Omoglymmius germari shows a similar picture, with only one recent record (2018) in the Pollino National Park (Basilicata) but a small number of active populations after 2000. Clinidium canaliculatum populations are in a much better conservation status, with about 50 new sites detected after 2000 in the Sila National Park. Threats and research/monitoring needs have been discussed for each species and new IUCN status proposed for Italian populations: Critically Endangered (CR) for Rhysodes and Omoglymmius, Near Threatened (NT) for Clinidium.

We focused on the coleopteran species assemblage in a tropical deciduous forest in the Bethuadahari Wildlife Sanctuary, West Bengal, India. During a 2-year survey, we collected 56 species belonging to 13 families of Coleoptera, in varying relative abundance. Among the species, 15 belong to the family Chrysomelidae, nine to the Staphyllinidae, and four to the Coccinellidae. Our results substantiate the importance of the Bethuadahari Wildlife Sanctuary for the conservation of coleopteran insects.

SummaryPopulations of the White-rumped Vulture Gyps bengalensis, Indian Vulture G. indicus and Slender-billed Vulture G. tenuirostris declined rapidly during the mid-1990s all over their ranges in the Indian subcontinent because of poisoning due to veterinary use of the non-steroidal anti-inflammatory drug diclofenac. This paper reports results from the latest in a series of road transect surveys conducted across northern, central, western and north-eastern India since the early 1990s. Results from the seven comparable surveys now available were analysed to estimate recent population trends. Populations of all three species of vulture remained at a low level. The previously rapid decline of White-rumped Vulture has slowed and may have reversed since the ban on veterinary use of diclofenac in India in 2006. A few thousand of this species, possibly up to the low tens of thousands, remained in India in 2015. The population of Indian Vulture continued to decline, though probably at a much slower rate than in the 1990s. This remains the most numerous of the three species in India with about 12,000 individuals in 2015 and a confidence interval ranging from a few thousands to a few tens of thousands. The trend in the rarest species, Slender-billed Vulture, which probably numbers not much more than 1,000 individuals in India, cannot be determined reliably.

AbstractWe compared the effectiveness of various methods for surveying medium and large wild mammals in southern Oman. Working with volunteers recruited by Biosphere Expeditions, wildlife professionals and local rangers, we used direct observation, camera traps, sign surveys (tracks and/or dung) and molecular scatology to study 66 sampling units of 2 × 2 km (grid cells) in an area of 32 × 36 km during a 4-week period in February–March 2011. Sixteen mammal species were recorded, and the largest numbers of species were recorded by sign surveys and camera traps (both n = 9); sign surveys, direct sightings and DNA scatology recorded species across the largest number of grid cells. For species with a sample size large enough for comparison (i.e. detected in ≥ 8 grid cells), DNA scatology proved most effective for detecting caracal Caracal caracal, signs for hyaena Hyaena hyaena, ibex Capra nubiana, porcupine Hystrix indica and hyrax Procavia capensis, and signs and direct sightings for mountain gazelle Gazella gazella. Clustering, in which records from multiple methods are either adjacent or overlapping, was highest (≥ 76%) for the wolf Canis lupus, porcupine, ibex and gazelle. Our results indicate the best methods to detect and record the distributions of individual species in the study area, and demonstrate the advantage of using multiple methods to reduce the risk of false absences or partial detections. Our findings also highlight the potential of clustering as a means of cross-checking results of observations that are skill-dependent, which is particularly useful when employing a large workforce.

AbstractThe Fairmead Landfill locality contains a diverse middle Irvingtonian, (0.78–0.55 Ma), vertebrate fauna that includes three sloths, Megalonyx wheatleyi, Nothrotheriops shastensis and Paramylodon harlani. The co-occurrence of these three genera in a single fauna is relatively rare in both the Irvingtonian and Rancholabrean and this is only the fourth documented Irvingtonian fauna to contain all three sloth genera. The presence of the three different sloths, each of which had different ecological requirements, indicates the presence of a variety of different habitats at this time and a heterogeneous landscape. Preliminary analysis of pollen from the site supports the interpretation of the existence of a mosaic of plant communities, but a landscape dominated by a mesic grassland. This interpretation is also supported by the total faunal diversity that includes taxa associated with woodlands as well as open habitat and taphonomic differences in the preservation and relative abundance of the different sloths. Evolutionarily the Fairmead Landfill sloths show a suite of morphological, size and proportional characters that indicate they represent transitional populations between older and younger members of their respective lineages.

The authors present a list of extinct, dying out and threatened species of vascular plants of the Sudeten Mts. (south-western Poland), based on their own field studies carried out since 1972, historical literature data, and herbarial collections. The list comprises 584 taxa, i.e. almost 33% of the Sudeten vascular flora. Sixty species were recognized as extinct and disappeared, 93 - as critically endangered, 161 - as endangered, 224 - vulnerable, and 12 - near threatened species. No definite kind of threat was ascribed to 34 taxa. Thus they were included in the group of ,data deficient" species. The paper presents also a quantitative analysis of all the species from the particular threat categories at the background of basic phytosociological groups. Besides, exemplary maps of the distribution of some of the Sudeten plants are given.

In order to estimate the diversity and status of avian species of Curzon Hall premises, University of Dhaka, Bangladesh, a study was conducted from January 2012 to January 2014. A total of 50 species of birds belonging to 30 families under 12 orders were recorded of which, regarding the relative abundance, 29 were common and 21 were uncommon. Twenty five species, in total, were identified as breeding residents, 13 as non-breeding residents and 12 as migrants. Of all the species identified from the study site, one was Critically Endangered (Alexandrine Parakeet Psittacula eupatria) and six were new for the campus (Taiga Flycatcher Ficedula albicilla, Indian Silverbill Lonchura malabarica, Ashy Drongo Dicrurus leucophaeus, Eurasian Wryneck Jynx torquilla, Pied Cuckoo Clamator jacobinus, Lesser Whistling Duck Dendrocygna javanica). Passerines were the dominating group as represented by 27 species from 16 different families. Species richness was in the highest peak in the late winter and early spring and comparatively less in other seasons.DOI: http://dx.doi.org/10.3126/eco.v20i0.11324Ecoprint: An International Journal of EcologyVol. 20, 2013Page : 1-8
