The territory of Pakistan has been influenced by biota from different geographic directions, and is divided zoogeographically into the Palearctic and Oriental regions (Khan 2006; Masroor 2012). This makes Pakistan one of the important territories in Eurasia in the understanding of past biodiversity dynamics. Well-known examples of Oriental elements among its amphibian fauna are observed in all four families of toads and frogs currently known from Pakistan: Bufonidae, Microhylidae, Megophryidae, and Dicroglossidae. In this short contribution, we focused on the species status and the origins of the genus Microhyla (Microhylidae), known from the north-eastern part (Punjab, Islamabad, and Azad Jammu and Kashmir; Masroor 2012) of the country. However, Sarkar (1984), also reported Microhyla from Bhuj in Gujarat, India, very close to the southern Pakistani province of Sindh. This genus has not yet been reported from the Palearctic region of the country and all currently known localities are from the Oriental parts of Pakistan (i.e. eastward of the Indus River). The genus is represented in the country by M. ornata (Duméril & Bibron, 1841), originally reported as Oxyglossus lima (Khan 1968). However, in view of the overall distribution and diversity of the genus based on genetic data (Garg et al. 2018, 2019; Gorin et al. 2020), it appears that populations from Pakistan could possibly have a different evolutionary history and be different taxon (see the currently scattered range of the genus between northern and western India and Pakistan; Fig. 1). Therefore, we tested this assumption using mitochondrial (mt) and nuclear (n) DNA data.

A New Species

A new species, Conogethes sahyadriensis sp. nov. (Lepidoptera: Crambidae), feeding on cardamom, is described from India. The species status is supported by diagnostic morphology as well as by genetic data. A phylogenetic analysis based on the publicly available Conogethes COI barcode sequences finds C. sahyadriensis as sister to C. pluto, and it further reveals a number of clades that potentially represent additional undescribed species.The new species is delineated from closely related and superficially similar species of Conogethes.

Abstract Decisions under the U.S. Endangered Species Act (ESA) require scientific input on the risk that the species will become extinct. A series of critiques on the role of science in ESA decisions have called for improved consistency and transparency in species risk assessments and clear distinctions between science input and policy application. To address the critiques and document the emerging practice of the U.S. Fish and Wildlife Service (USFWS), we outline an assessment process based on principles and practices of risk and decision analyses that results in a scientific report on species status. The species status assessment (SSA) process has three successive stages: 1) document the life history and ecological relationships of the species in question to provide the foundation for the assessment, 2) describe and hypothesize causes for the current condition of the species, and 3) forecast the species' future condition. The future condition refers to the ability of a species to sustain populations in the wild under plausible future scenarios. The scenarios help explore the species' response to future environmental stressors and to assess the potential for conservation to intervene to improve its status. The SSA process incorporates modeling and scenario planning for prediction of extinction risk and applies the conservation biology principles of representation, resiliency, and redundancy to evaluate the current and future condition. The SSA results in a scientific report distinct from policy application, which contributes to streamlined, transparent, and consistent decision-making and allows for greater technical participation by experts outside of the USFWS, for example, by state natural resource agencies. We present two case studies based on assessments of the eastern massasauga rattlesnake Sistrurus catenatus and the Sonoran Desert tortoise Gopherus morafkai to illustrate the process. The SSA builds upon the past threat-focused assessment by including systematic and explicit analyses of a species' future response to stressors and conservation, and as a result, we believe it provides an improved scientific analysis for ESA decisions.

The holothuroid species collected by The British, Australian and New Zealand Antarctic Research Expedition (BANZARE) are listed, with some systematic annotations. A previous report by O’Loughlin on some BANZARE holothuroids is revised and incorporated. Four new species are described: the Antarctic dactylochirotid Echinocucumis kirrilyae sp. nov.; the Kerguelen dendrochirotid Clarkiella deichmannae sp. nov.; the Antarctic dendrochirotids Trachythyone cynthiae sp. nov. and Trachythyone mackenzieae sp. nov. Cucumaria serrata var. intermedia Théel from Heard and Kerguelen, and Cucumaria serrata var. marionensis Théel from Marion, are raised to species status, and assigned to Pseudocnus Panning. Cucumaria (Semperia) ekmani Ludwig & Heding is a junior synonym of Cucumaria kerguelensis Théel. Cucumaria kerguelensis is re-assigned to Neopsolidium Pawson. Thyone recurvata Théel and Cucumaria squamata Ludwig are junior synonyms of Trachythyone muricata Studer. Cucumaria (Semperia) bouvetensis Ludwig & Heding is formally re-assigned to Trachythyone. Trachythyone baja Hernández is a junior synonym of Trachythyone bouvetensis (Ludwig & Heding). Molecular genetic data indicate possible allopatric cryptic Antarctic forms for the morpho-species Laetmogone wyvillethomsoni Théel. A table with all species and station data is provided.

The current use of serum retinol concentrations as a measurement of subclinical vitamin A deficiency is unsatisfactory for many reasons. The best technique available for vitamin A status assessment in humans is the measurement of total body pool size. Pool size is measured by the administration of retinol labelled with stable isotopes of carbon or hydrogen that are safe for human subjects, with subsequent measurement of the dilution of the labelled retinol within the body pool. However, the isotope techniques are time-consuming, technically challenging, and relatively expensive. There is also a need to assess different types of tracers and doses, and to establish clear guidelines for the use and interpretation of this method in different populations. Field-friendly improvements are desirable to encourage the application of this technique in developing countries where the need is greatest for monitoring the risk of vitamin A deficiency, the effectiveness of public health interventions, and the potential of hypervitaminosis due to combined supplement and fortification programs. These techniques should be applied to validate other less technical methods of assessing vitamin A deficiency. Another area of public health relevance for this technique is to understand the bioconversion of β-carotene to vitamin A, and its relation to existing vitamin A status, for future dietary diversification programs.
