Abstract

The number of exotic freshwater ornamental fish species released from the aquarium trade in Iran has been increasing in recent years. All recorded exotic aquarium fishes are listed here, including 8 species in 7 genera, 5 families, and 5 orders. The introduced species belong to the Neotropical, Nearctic and Palearctic fish elements. Their distribution ranges within Iranian freshwater ecosystems are given, and the presence of Koi (ornamental Cyprinus carpio) are recorded for the first time from Iranian inland waters. Eradication programs need to be accompanied by a public awareness campaign to ensure that the aquarium trade and hobbyists do not release these pet fishes into natural habitats.

Abstract

A checklist of the croakers of the world, family Sciaenidae, is presented. A total of 584 nominal species belonging to 289 valid species and 69 genera is included. Four genera, Johnius with 32 species, Cynoscion 25, Stellifer 24, and Umbrina 17 contains 30% of the species, whereas 43% of the genera (31) are monotypic. Eques is a valid genus-name and should be used instead of Equetus. Fourteen nominal species remain unidentifiable and are placed in incertae sedis, whereas 12 nominal species currently described in sciaenid genera lay outside the family. Among this latter group two of them represent senior synonyms of well-established species: Sciaena guttata Bloch and Schneider, 1801 and Sciaena pallida Walbaum, 1792 predate Giuris margaritaceus (Valenciennes, 1837) and Cymolutes praetextatus (Quoy and Gaimard, 1824), respectively, and they are here declared nomina oblita.

Abstract

In wildlife management, sufficient information about fauna is vital for conservation of species and their habitats. Furthermore, the number of bird species in a habitat can represent an index of habitat quality. Therefore, this study was carried out to identify bird fauna on a university campus (i.e. Agricultural Sciences and Natural Resources University of Khuzestan, abbreviated as ASNRUKH) in the southwest of Iran in order to determine the number of bird species, the day of their arrival, and the presence time of migratory birds on campus. Field survey and identification of birds were carried out in the study area, with an area of 72.9 ha, using binoculars from June 2017 to May 2018 in linear transects spaced 20 meters apart. We identified 62 bird species, including nine raptors, which is equal to 11.25% of bird species in Iran. In total, 19 residents, five summer visitors, 21 winter visitors and 17 passing migratory birds were identified. The lowest co-occurrence number of species (21–25) was observed from middle June to early October and the maximum number of concurrent species (38–41) were recorded from late November to early January. The Western Barn Owl Tyto alba was the only resident raptor, which is part of an integrated pest management system throughout the year. ASNRUKH’s long-established persistent favorable microclimate supports both resident and migratory birds. In addition, the study area provides food and safety for migratory birds from across the globe as a stopover site.

Abstract

Iran is a country with a very rich mammal fauna, including such iconic species as the Asiatic cheetah Acinonyx jubatus (Griffith), the Persian leopard Panthera pardus saxicolor Pocock, the Mesopotamian fallow deer Dama mesopotamica (Brooke), and the Asiatic wild ass Equus hemionus Pallas. There are no less than eight species of cat (Felidae) living in Iran today, and until recently there were even two more (the Caspian tiger Panthera tigris virgata (Illiger) and the Asiatic lion Panthera leo persica (Meyer)). For comparison, the whole European continent harbours a mere three felids. A recent atlas now adds to our knowledge on this spectacular mammalian line-up and its dissemination. The book, also available as a pdf, by Karami, Ghadirian and Faizolahi lists 183 terrestrial and 16 aquatic species of mammals (including the Caspian tiger and Asiatic lion), from the dugong and the Caspian seal Pusa caspica (Gmelin) to whales and dolphins, bats (Chiroptera) and rodents (Rodentia), from Perissodactyla to Lagomorpha and from Carnivora to Chiroptera ...

Abstract

It is a truism that mammalian systematics is a dynamic field of research and that new species are still being discovered. The rate of change, however, is truly spectacular and the number of mammal species, estimated at 5,416 in 2005 (Wilson and Reeder, 2005) reached 6,495 just 13 years later (Burgin et al., 2018), i.e. an astonishing rise of 20%. Behind this progress is the wide application of new research tools, above all, highly effective DNA-based methods capable of reconstructing evolutionary pathways and delimiting morphologically cryptic species. Faunal revisions are as badly needed in this time of taxonomic revolution as ever before. They are of particular value when done by experts active in the fields of taxonomy research and species delimitation. It was therefore a pleasant surprise to receive a new publication of this kind which focuses on the rodents of Taiwan ...

Abstract

We re-address the findings of recent publications on herpetofaunal diversity of certain urban areas of Gujarat, India, in which, authors have claimed to report nine frogs and two lizard species for the first time from the State, without any morphological data and/or voucher specimens. We present our critique and comments, with the known distributional ranges of these species and on these erroneous records. We also advocate removal of such species from the faunal list of Gujarat until confirmed reports, based on correctly identified vouchers, are presented. We recommend here that identification of a species should be done following standard protocols and by facilitating the deposition of voucher specimen/s in responsible public repositories for studies involving taxonomy, morphology and range extension.

Abstract

In this study we document the consistent presence of the long distant migrant pipits including, Blyth’s Pipit, Tawny Pipit, Tree Pipit, Olive-backed Pipit, and Richard’s Pipit in the district of West Midnapore (Paschim Medinipur) in West Bengal state, India. We confirm via photography the record of Blyth’s and Tawny Pipits for the first time in this part of the world.

Abstract

Turkey is biogeographically diverse and consequently has a rich herpetofauna. As a result of active herpetological research, the number of species has steadily increased in recent years. I present here a new checklist of amphibian and reptile species distributed in Turkey, revising the nomenclature to reflect the latest taxonomic knowledge. In addition, information about the systematics of many species is also given. In total 35 (19.4%) amphibian and 145 (80.6%) reptile species comprise the Turkish herpetofauna. Among amphibians, 16 (45.7%) anurans and 19 urodelans (54.3%) are present. Among reptiles, 11 (7.6%) testudines, 71 (49%) saurians, 3 (2.1%) amphisbaenians and 60 (41.3%) ophidians are considered part of the herpetofauna. The endemism rate in Turkey is considered relatively high with a total of 34 species (12 amphibian species – 34.3% and 22 reptile species – 15.2%) endemic to Turkey, yielding a total herpetofaunal endemism of 18.9%. While 38 species have not been threat-assessed by the IUCN, 92 of the 180 Turkish herpetofaunal species are of Least Concern (LC), 13 are Near Threatened (NT), 10 are Vulnerable (VU), 14 are Endangered (EN), and 7 are Critically Endangered (CR). In addition, 6 species are in the DD (Data Deficient) category.

Abstract

The world currently recognizes 214 species of Caecilians (Amphibia: Gymnophiona) most of which occur in the wet tropics and some adjacent subtropical regions. Of the ten-family classification known, three occur in Asia, viz. Chikilidae (endemic to northeast India, Indotyphlidae (India’s Western and Eastern Ghats) and Ichthyophiidae. However, until this report, there were no confirmed reports of any caecilian species from Bhutan, although their presence has been assumed likely given their occurrence in adjacent countries. This report provides the first confirmed report of caecilians in Bhutan with work to identify the species to be carried on later with further research.

Abstract

Jakhor Taal is an ox-bow perennial lake, situated in Dhangadhi sub-metropolitan city in Kailali district, Nepal. The present study focuses on the factors determining fish diversity, socio-economic status of fishing communities and conservation challenges of Jakhor Taal. Fish sampling was done by gill net, cast net and other local fishing techniques such as Helka and Tiyari nets and Dhadiya trap. A total of 24 fish species (8 exotic and 16 native) were recorded belonging to 7 orders, 14 families and 22 genera. The order Cypriniformes was found to be highest, obtaining 41.66% of the total fish species recorded and 65.38% of total fish caught during the study period (February 2019 - August 2019) followed by Siluriformes (20.33%) and Perciformes (16.67%), respectively. The Shannon-Weiner diversity index was found highest (2.93) in winter (February) and lowest (2.76) in summer (July). Similarly, the Simpson and Evenness values were also found slightly higher during winter (February) in comparison to summer (July). The Shannon-Weiner diversity index was found highest (2.73) at station II in comparison to station I, III, and IV where it was 2.31, 2.09, and 2.04, respectively. Results from the Redundancy analysis (RDA) revealed that the environmental variables such as water temperature, depth and dissolved oxygen were found to be highly significant to most of the fish species at different stations and months. However, pH and free CO2 was not shown to have any relationship or significance. Altogether, 22 clusters were formed in which exotic species show highly significant clustering in comparison to native species. The socio-economic status of the local fishing communities is below the poverty line and the lake and its fishing resources play vital roles in their diet and income source. In the context of conservation challenges and implications, this lake is highly neglected by both governmental and local communities and this negatively affects its natural properties through habitat destruction, illegal fishing, urbanization, invasive species, and a general lack of awareness.

Abstract

Herpetological diversity of the Eastern Ghats hill range in the Indian peninsula has been mostly overlooked and incompletely documented. We here present information on the amphibian and reptile diversity in the poorly-explored Central Eastern Ghats hill range in peninsular India. Based on a 1,000-hour bio-inventory study of the series of ranges between the Palar River (abutting Tamil Nadu) and the Krishna River (abutting Telangana) for about 10 months (300 field days), we present the following results. A total of 105 species of herpetofauna, consisting of 24 amphibian species, 35 lizard species, 42 snake species and 4 chelonian species were documented. Several new range extension records and new findings of rare species are discussed, substantiated by photo-vouchers, pre-existing museum specimens or both.

Abstract

We present the first confirmed report of the Long-snouted Bhutan Squirrel Dremomys lokriah bhotia from the state of West Bengal, India. Previously the subspecies was known from limited localities of East Sikkim (India) and Bhutan. This article, thus, adds to the global knowledge of the subspecies with a note on its habitat and activity pattern, along with new details on it’s current global distribution.

Abstract

Many users of taxonomic lists believe them to be based on consistent data, but this is rarely true, and biased knowledge may be the rule rather than the exception. In the present essay on the taxonomy of primates of the Horn of Africa, I show how taxonomic history has consequences for the present appreciation of primate diversity in the region, and thus in directing conservation efforts. To minimize future losses, it is necessary that international bodies recognize taxonomic checklists as works in progress, eventually encouraging further integrated approaches to taxa delimitation.

Abstract

A rarely recorded small carnivore, the Spotted linsang (Prionodon pardicolor), is among Asia’s least studied members of the family Prionodontidae. We report the first photographic evidence of its presence from the Tashigang Forest Division of eastern Bhutan. A non-invasive camera trap survey during the nationwide tiger survey in 2014–2015 and an opportunistic wildlife monitoring exercise in 2020 photo trapped the species on two independent occasions. On the first occasion the individual was recorded at the altitude of 2,308 m a.s.l. and the later at 2,952 m a.s.l. The main threats to the species in the region are not currently well known, highlighting the importance of additional studies to ascertain its distribution and status in the Tashigang Forest Division.

Abstract

In this review, an updated checklist of spider diversity in Rajasthan, India is presented. A total of 173 spider species from 90 genera belonging to 25 families are listed with records/descriptions originating from only 20 out of 33 districts of Rajasthan. A total of 74 taxa recorded from various districts of Rajasthan were identified only up to generic level. The maximum number of spider species were recorded from Jodhpur district (72 species), followed by Ajmer (69 species), Bharatpur (66 species), Pali (63 species), Jaipur (58 species), Dholpur and Karauli (38 species each), Jhunjhunu and Sikar (31 species each), Sri Ganga Nagar (26 species), Hanumangarh (25 species), and Jaisalmer (26 species). A fewer number of species are known from other districts. Thus far, no faunal surveys of spiders have been conducted in 13 districts of Rajasthan. Most of the national parks and wildlife sanctuaries, forest areas, agricultural fields, human dwellings, etc. within the state still await intensive and extensive surveys to record the spider fauna.

Abstract

Although recent molecular data has advocated the distinct position of Arvicola persicus De Filippi from Iran, karyotypic and differential chromosome staining data, informative tools to describe biological diversity, are lacking. Here we present the first description of the chromosome complement of A. persicus from its type locality in Sultaniyeh, southern Alborz Mountains, Iran. Though the diploid chromosome number (2n= 36) and the fundamental number of autosomal arms (FNa= 60) did not deviate from that reported for Arvicola amphibius sensu lato in Eurasia (2n= 36, FNa= 6068), there appear to be significant differences between A. persicus and A. amphibius s.l. in terms of C-bands and NOR-bearing autosomes. Banded karyology, therefore, provides further evidence for delimiting A. persicus as a species, which is distinct from A. amphibius.

Abstract

Two new heterotardigrade (Tardigrada) species, Bryodelphax pucapetricolus sp. nov. and Bryodelphax wallacearthuri sp. nov., are described from moss associated with limestone pavement in the Republic of Ireland. The species description process for these two taxa initiated a more detailed exploration of several morphological characters of importance in Bryodelphax Thulin including cuticular sculpture elements and ventral plate morphology. Division of the third dorsal median plate in the context of the genera Bryochoerus Marcus and Bryodelphax is further discussed. We recommend minor emendations to the generic diagnoses of Bryochoerus and Bryodelphax. Also, we emend the species diagnoses of Bryodelphax aaseae Kristensen, Michalczyk and Kaczmarek and Bryodelphax parvuspolaris Kaczmarek, Zawierucha, Smykla and Michalczyk, record the genus Parechiniscus Cuénot from the Republic of Ireland for the first time, and make suggestions relevant to the taxonomy of limnoterrestrial heterotardigrades.

Abstract

In Bhutan, protected areas constitute 51.4% of the total geographical area, out of which 7.7% is designated biological corridors (BCs) that serve as connectors between protected areas. The biological corridor (BC-03) constitutes a total area of 407.7 km² and connects Phibsoo Wildlife Sanctuary in the west, Jigme Singye Wangchuck National Park and Royal Manas National Park in the north and southeast through Sarpang–Tsirang District landscapes. However, most BCs, including BC-03, lack comprehensive inventories of mammal species. We conducted joint rapid biodiversity assessment (RBA) using camera trap surveys from November 2019 to February 2020. Our findings from BC-03 include records of 26 mammal species belonging to 11 families in five orders. Nearly half of these species are listed as Endangered, Vulnerable, or Near Threatened. Overall, the BC-03 landscape was found to support 77.8% of the mammal species of Sarpang District and 21.7% of Bhutan (as per Biodiversity Statistics of Bhutan, 2017). Therefore, BC-03 is of conservation interest. Comprehensive conservation plans, periodic monitoring of keystone species, and restrictions on the expansion of cardamom plantations in BCs are suggested for securing wildlife habitats and ensuring long-term persistence of keystone species, including within BC-03 in southcentral Bhutan.

Abstract

The book by Boris Kryštufek and Georgy I. Shenbrot, published a few weeks ago, is an encyclopaedic masterpiece and up-to-date standard work on the rodent group of Arvicolinae Gray, 1821 (voles and lemmings) belonging to the family Cricetidae Fischer, 1817 (hamsters). The authors are two experts on these mammals, and are known worldwide by scientists working in mammalogy for their publications. In addition to countless individual articles, B. Kryštufek is best known for his monograph on the ‘Mammals of Turkey and Cyprus’, which he published together with Vladimír Vohralík (Kryštufek and Vohralík, 2001; 2005; 2009). Georgy Shenbrot wrote, among many other books and papers, mainly devoted to desert and steppe rodents, ‘An Atlas of the Geographic Distribution of the Arvicoline Rodents’ in co-operation with Boris Krasnov (Shenbrot and Krasnov, 2005). It is certainly no exaggeration to call the present book, reviewed here, a worthy, up-to-date successor to Hinton's classic ‘Monograph of Voles and Lemmings’ (Hinton, 1926) and Gromov and Polyakov's volume on ‘Voles (Microtinae)’ (Gromov and Polyakov, 1977) in the framework of the ‘Fauna SSSR’ series (which actually always represented the entire group worldwide). So, one can say that a fundamental work on voles appears about every 50 years.
