The present work explicates three species of genus Schwetschkeopsis Broth. belonging to family Myriniaceae Schimp., which have been encountered for the first time in central India at Pachmarhi Biosphere Reserve. Previously, this genus was known to be distributed at Himalayan and South Indian bryogeographical regions of India with four valid species, of which none were reported from central India. The genus is important as it is the only genus of family Myriniaceae known from India out of the total seven known worldwide and this study highlights the extension of its range of distribution in the country. During the present study three taxa viz. Schwetschkeopsis fabronia (Schwaegr) Broth., Schwetschkeopsis formosana Nog., Schwetschkeopsis elongata (Dixon and P. Varde) P. Varde were identified from the Biosphere Reserve. S. fabronia was encountered as terrestrial moss growing on dry exposed rocks while S. formosana and S. elongata were epiphytic. The presence of three taxa of the important genus Schwetschkeopsis at central India accentuates the importance of the central Indian moss flora as out of four species present in India three occur in this zone.

Objective: To calculate the monthly relative abundance of Thysanoptera species, according to the Margalef, Simpson and Shannon-Wiener diversity indices. Design / Methodology / Approach: The work was carried out in three geographic units with conventional management, during January-December, 2019 in the Reserva de la Biosfera Zicuirán-Infiernillo (Biosphere Reserve), Michoacán, Mexico. In each unit, 10 trees were selected through simple random sampling. Thrips counts were performed on ten shoots per tree every 15 d, for a total of 7200 shoots in the three geographic units. Thysanoptera individuals were placed in entomological jars. The variables were: number of thrips collected per shoot in sampled tree and geographic unit (orchard). To estimate the specific richness and structure of species, the program "calculation of diversity indices DIVERS" was used. Results: In the three geographical units studied, the recorded presence of Thysanoptera accounted for 12 to 17 species. For Nueva Italia 12 recorded species, two were permanent (16.66%), five abundant (41.66%), one scarce (8.3%) and four rare (33.33%). In Zicuirán, three species were permanent (17.64%), six abundant (35.29%), two scarce (11.76%) and six rare (35.29%). In Los Hoyos, four species were permanent (26.66%), four abundant (26.66%) and seven rare (46.66%). The abundance of species was represented by the genus Frankliniella and the species Scolothrips sexmaculatus and Scirtothrips citri. The highest species richness and abundance was found from January to May. In October and November, the value of the calculated indices was zero, which shows less richness and abundance of individuals. The best species uniformity was recorded during January and December, which meant a more stable and homogeneous relation. Study limitations/Implications. Pest resurgence, presence of Candidatus Liberibacter spp. and its vector Diaphorina citri. Findings / Conclusions: in Nueva Italia, 12 species were taxonomically determined; in Los Hoyos 15, and in Zicuirán 17 species, which are reported for the first time in the state of Michoacán, Mexico. At the geographic unit "Los Hoyos" diversity was higher, uniform and stable.

The aim of the publication is to determine the prerequisites of and to elaborate on the foundations of the Exclusion Zone reintegration in order to address the issue of rational development of urban-planning documentation complex regarding the legitimacy of said territory exploitation. It is established that for the implementation of the «Radioactive waste management strategy» the production complex «Vector» is being constructed on the Exclusion Zone territory; a powerful park of renewable energy generation is being created to implement the «Chornobyl - a Territory of Change» strategy; a Chornobyl Radiation-Ecological Biosphere Reserve was established to support and increase the barrier function of the zone; in order to promote the Safe Chornobyl brand-name, the tourist traffic is being increased and the conditions for the visitors are improving. In the absence of developed and approved city planning documentation, the listed above causes the problem of legitimacy and rationality of the exclusion zone territory use. The paper for the first time raises the question of the need to elaborate the concept of functional planning of the Chornobyl NPP exclusion zone territory and the development of the design-planning complex (urban planning documentation): from the territory.

Background: Red cell inherited hemoglobin anomalies are commonly encountered in the central region of India. These cause a public health concern due to high degree of morbidity, mortality, and fetal loss in the backward, underprivileged, and vulnerable people. Purpose: To report five typical families of hemoglobin E disorders identified for the first time in the state of Madhya Pradesh from central India. Methods: Out of a total of 445 couples/families (excluding the present study) with 1526 persons (848 males and 678 females) referred from a tertiary hospital in central India for investigations of anemia/hemoglobinopathies during the period from March 2010 to February 2014, we came across five typical rare couples/families of hemoglobin E disorders worthy of detailed investigations. Laboratory investigations were carried out following the standard procedures after cross checking for quality control from time to time. Results: For the first time, we have encountered nine cases of heterozygous hemoglobin E trait, two members with hemoglobin E-β-thalassemia (double heterozygosity), two cases of sickle cell-hemoglobin E disease (double heterozygosity), and none with homozygous hemoglobin E. Cases  of hemoglobin E trait, hemoglobin E-β-thalassemia, sickle cell-β-thalassemia and sickle cell-E disease showed moderate to severe anemia, and target cells, and reduced values of red cell indices like RBC, Hb level, HCT, MCV, MCH and MCHC, representing abnormal hematological profile and clinical manifestations before blood transfusion. Conclusions: Double heterozygosity for hemoglobinopathies such as occurrence of β-thalassemia mutation with structurally abnormal hemoglobins (Hb S and Hb E) is a rare entity, but occurs with severe clinical manifestations only in those areas or communities where these are highly prevalent, testifying the migrations and genetic admixture. Distribution of hemoglobin E and β-thalassemia in different districts of Madhya Pradesh indicates that abnormal Hb E gene has wide spread and needs prevention for the rehabilitation of vulnerable people in central India.

A combined approach based on karyology and DNA taxonomy allowed us to characterize the taxonomic peculiarities in 10 Mesoamerican lizard species, belonging to six genera and five families, inhabiting two Biosphere Reserve in Chiapas, Mexico: La Sepultura Biosphere Reserve, and Montes Azules Biosphere. The karyotypes of four species, Phyllodactylus sp. 3 (P. tuberculosus species group) (2n = 38), Holcosus festivus (Lichtenstein et von Martens, 1856) (2n = 50), Anolis lemurinus Cope, 1861 (2n = 40), and A. uniformis Cope, 1885 (2n = 29–30) are described for the first time, the last one showing a particular X1X1X2X2/X1X2Y condition. In Aspidoscelis deppii (Wiegmann, 1834) (2n = 50) and Anolis capito Peters, 1863 (2n = 42), we found a different karyotype from the ones previously reported for these species. Moreover, in A. capito, the cytogenetic observation is concurrent with a considerable genetic divergence (9%) at the studied mtDNA marker (MT-ND2), which is indicative of a putative new cryptic species. The skink Scincella cherriei (Cope, 1893), showed high values of genetic divergence (5.2% at 16S gene) between the specimens from Montes Azules and those from Costa Rica and Nicaragua, comparable to the values typical of sister species in skinks. A lower level of genetic divergence, compatible with an intraspecific phylogeographic structure, has been identified in Lepidophyma flavimaculatum Duméril, 1851. These new data identify taxa that urgently require more in-depth taxonomic studies especially in these areas where habitat alteration is proceeding at an alarming rate.
