AbstractConservation organisations are tasked with protection of biodiversity but are challenged by limited resources; consequently, the highest conservation priority species have designations that should correspond with the level of protection needed. In Britain, the saxicolous Calicium corynellum receives the highest conservation priority as a consequence of its rarity, combined with dramatic population declines over the last several decades, having disappeared from 2 of its 4 British sites and declined in one other. However, there is some uncertainty associated with the taxonomic status of the entity referred to as C. corynellum in Britain, partly because its common congener, C. viride has been recorded on trees overhanging several of the populations of C. corynellum, but also because the morphology of British material is very similar to the common C. viride, but found on rock. Standard fungal barcode nr ITS sequences of C. corynellum from both extant British populations of C. corynellum were successfully amplified, along with C. viride from trees overhanging one of the sites and from other British sites. In addition, morphological features were compared among specimens of both taxa. There is no evidence to support the distinction of British C. corynellum from its more common congener, and its conservation status is Britain should be re-evaluated.

The distribution and abundance of the white-tailed jackrabbit Lepus townsendii have declined significantly since 1950, continuing a trend that began in some regions of its range in the late 1800s. We reviewed museum records and the literature to evaluate the status of the white-tailed jackrabbit in each state and province in its historical range and evaluated possible reasons for its decline. Our evaluation revealed its extirpation or decline throughout much of its range, but its legal or conservation status does generally not reflect this precarious status. We note its extirpation in Missouri, Kansas and Oklahoma, and potential extirpation in British Columbia, Oregon, Illinois, and Wisconsin. We classified the white-tailed jackrabbit to be broadly extirpated in Iowa, Minnesota, Washington, Nebraska and California, and declining with local extirpations in Wyoming, Nevada, Utah, Colorado, New Mexico, and South Dakota. We consider it to be a relict in Ontario, and possibly declining in Alberta, Saskatchewan, North Dakota, Idaho, and Montana. We consider only Manitoba to have a possibly stable population. Determining the reasons for the species' reduced distribution is difficult, as the decline appears to be due to multiple factors, none of which provide a universal explanation. We dismissed road kills, recreational hunting, disease and parasites, and competition with black-tailed jackrabbits Lepus californicus as causes of the widespread population declines and extirpations. We concluded that habitat alterations and climate change are overriding factors, and that past depredation measures and increased predator populations have likely contributed to the decline. These hypotheses require further testing. We recommend more research on the distribution, abundance, ecology, and population dynamics of white-tailed jackrabbits, and management that includes a frank appraisal of the species' status, the potential for grassland restoration, and programs to reintroduce populations into prairie preserves and restored grasslands.

Hunchback darkling beetles of the Ibero-Maghrebian genus Misolampus Latreille, 1807 (Tenebrionidae, Stenochiinae) encompass six species: M. gibbulus (Herbst, 1799), M. goudotii Guérin-Méneville, 1834, M. lusitanicus Brême, 1842, M. ramburii Brême, 1842, M. scabricollis Graells, 1849, and M. subglaber Rosenhauer, 1856. Previously known distribution ranges of the species were delineated using many old records, the persistence of such populations being questionable under the current situation of global biodiversity loss. Additionally, the status of geographically isolated populations of the genus have been the subject of taxonomic controversy. An exhaustive bibliographical revision and field search was undertaken, and the Misolampus collection of the Museo Nacional de Ciencias Naturales (MNCN-CSIC) was revised. The aims are to (i) provide an updated geographic distribution range for the species of Misolampus; (ii) to determine the taxonomic status of controversial populations; (iii) to provide a catalogue for Misolampus; and (iv) to discuss the conservation status of these saproxylic beetles. As a result, a catalogue including synonymies and type localities, geographical records, diagnoses, and information on natural history for all species of Misolampus is presented. The results reveal that the distribution ranges of the species of Misolampus have not undergone a reduction in the last century, and indicate the presence of the genus in areas where it had never been recorded before. The morphological variability of M. goudotii drove the proposal of different taxa that are here formally synonymised as follows: M. goudotii Guérin-Méneville, 1834 = M. erichsoni Vauloger de Beaupré, 1900, syn. nov. = M. peyerimhoffi Antoine, 1926, syn. nov.

The present study was aimed at recognizing the status of 28 endemic plants of Bangladesh and determining their conservation management strategies. These endemics belong to 17 angiosperm families and constitute about 0.78% of the total species of the country. Of these endemics, 2 species were least concern, 10 rare and 7 endangered, and need to give immediate conservation priority. Another 9 endemics were assessed to be extinct since no report of collection for more than 100 years was available and could not be traced in the wild. An enumeration of these endemics is presented, each cited with updated nomenclature, bangla names, type, habit, ecology, potential values, places and status of occurrence, threats to the species, conservation status for sustainable management strategies. List of examined specimens of these endemics, wherever available, is also provided. Photographs of 24 endemics are also presented.

As part of an investigation into the status of the near threatened Gotland grass snake, Natrix natrix gotlandica Nilson & Andrén, 1981, endemic to the island of Gotland, we discovered that Linnaeus’ type series of the common grass snake, Natrix natrix (Linnaeus, 1758), is comprised of specimens from three different currently recognized species.                To stabilize the usage of the name Coluber natrix, we investigate Linnaeus’ type series, and a specimen which Linnaeus in 1741 examined west of the Swedish city of Nyköping is designated lectotype. The lectotype has since been lost, and a newly collected specimen from the same locality is designated neotype for Coluber natrix. The neotype is deposited in the herpetology collection of the Swedish Museum of Natural History in Stockholm, Sweden, catalog number NRM 8260.

A complex of morphological features of the genera Dictyonota Curtis, 1827, Kalama Puton, 1876 and Derephysia Spinola, 1837 (Heteroptera: Tingidae: Tinginae), inconsistent with the characters of the tribe Ypsotingini Drake et Ruhoff, 1965, is discussed. The common morphological features of these genera together with those of Acalypta Westwood, 1840, which do not correspond to the characters of Tingis Fabricius, 1803, as the type genus of the tribe Tingini Laporte, 1832, are presented. The data on the sex chromosome system X0/XX of these four genera, radically different from that of all the other 17 so far karyotyped Tinginae genera (XY/XX), are summarised. The closely related genera Acalypta, Dictyonota, Kalama and Derephysia are united in a tribe under the resurrected valid name Acalyptini [Acalyptaini; ICZN Case 3813, in press] Blatchley, 1926 according to the principle of priority (ICZN, Article 23). A diagnosis of the resurrected tribe Acalyptini based on morphological and karyological characters and an improved key to the genera Acalypta, Dictyonota, Kalama and Derephysia are given.

The COVID-19 pandemic initially started from the Wuhan capital city of Hubei Province in the People's Republic of China had now led to a severe public health hazard across the globe, the recorded death is approximately 958 thousand globally and counting. With the enormous amount of spread of the disease, a severe crisis for Personal Protective Equipment (PPE) is being noticed across the globe. Face masks being the first line of defence for all the healthcare workers as well for the common public. It became mandatory to wear face masks before entering the patient care area. The countries who are not manufacturing it locally had to depend on other countries for the procurement. As there is a severe supply chain disruption due to the lockdown measures taken by all the countries to contain the disease, so it had become difficult to procure the face masks from the manufacturing countries. The price for these PPEs is also rising at an alarming rate with the increase in the COVID-19 cases and the huge rate of consumption by the healthcare and other sectors. Therefore, with limited resources, the hospital has to run its services. The CDC, WHO and ICMR have released several guidelines from time to time for sterilization and reuse of face masks. This article will discuss the various methods that can be utilized to sterilize the face masks and reuse of it.

The common snook is one of the most abundant and economically important species in the Usumacinta basin in the Gulf of Mexico, which has led to overfishing, threatening their populations. The main goal of the present study was to assess the genetic diversity and structure of the common snook along the Usumacinta River in order to understand the population dynamics and conservation status of the species. We characterized two mitochondrial markers (mtCox1 and mtCytb) and 11 microsatellites in the Usumacinta basin, which was divided into three zones: rainforest, floodplain and river delta. The mitochondrial data showed very low diversity, showing some haplotypic diversity differences between the rainforest and delta zones. In contrast, we consistently recovered two genetic clusters in the Usumacinta River basin with the nuclear data in both the DAPC and STRUCTURE analyses. These results were consistent with the AMOVA analyses, which showed significant differences among the genetic clusters previously recovered by DAPC and STRUCTURE. In terms of diversity distribution, the floodplain zone corresponded to the most diverse zone according to the mitochondrial and nuclear data, suggesting that this is a transition zone in the basin. Our results support the relevance of the molecular characterization and monitoring of the fishery resources at the Usumacinta River to better understand their connectivity, which could help in their conservation and management.
