<em>Microstoma protracta</em> (Fr.) Kanouse is a strictly protected species in Poland, which is also present on the red list with the category R (rare). In Poland, there are five known localities for the species, including four historical sites discovered at the beginning of the twentieth century and one contemporary site discovered at the end of the twentieth century. In this paper, we present two new localities for <em>M. protracta</em>, discovered in April 2006 in Czeszewo (Wielkopolska Lowland, Jarocin Forest District) and in April 2017 in Krakow-Tyniec (Krakow-Częstochowa Upland, Myślenice Forest District). Sequences of the nuclear ribosomal DNA internal transcribed spacer regions of sporocarps from contemporary localities have been deposited in the GenBank database. This is the first record of the DNA barcode for this species. According to Criterion D of the IUCN recommendations, it has been suggested that <em>M. protracta</em> should be considered as a critically endangered species (CR: D) in Poland.

Jerdon's baza Aviceda jerdoni is one of the least studied raptor species in Nepal which is listed as a Critically Endangered species in the ‘Nepal's Red List of Birds’. This paper presents the records of this species during opportunistic surveys, conducted in 2018/2019 from Ilam and Jhapa districts of eastern Nepal. A total of 18 individuals were sighted during the study period with the first record of nest of the species in Nepal. The sightings were made between 70 m, the lowest global known range to 1048 m from mean sea level, and the highest altitudinal record for Nepal. Hunting and unintentional prey poisoning were identified as major threats for species in the study site.

The Status

The second regional list of threatened lichens and allied fungi is presented. The list is a result of investigation studies in North-Eastern Poland. In physicogeographic regionalization this area comprises 4 macroregions: Staropruska Lowland, Litewskie (Lithuanian) Lakeland, Mazurian Lakeland and South Podlasie Lowland. It is characterized by the presence of large forest complexes, including the Białowieża Old-growth Forest, the Knyszyńska Old-growth Forest, the Augustowska Old-growth Forest, the Romincka Old-growth Forest, the Borecka Old-growth Forest and the Piska Old-growth Forest. The status of threat to the lichen and allied fungi species listed has been determined according to the IUCN Red List Categories in version 3.1 (2001). The data obtained were compared with historical ones. Changes of the species main frequency were used as an additional indicator of their threat status. The Red List includes 310 taxa of lichens, lichenicolous and saprobic fungi, which constitute 52% of the NE Poland total lichen biota and 19.4% of Polish biota. The status of threatened biota has the following categories: Regionally Extinct (RE) -49 taxa, Critically Endangered (CR) - 58, Endangered (EN) - 41, Vulnerable (VU) - 39, Near Threatened (NT) - 24, Least Concern (LC) - 19 and Data Deficient (DD) - 80. Epiphytes constitute 84% of extinct and critically endangered species.

The distribution of Sonchus palustris in Slovakia was studied using herbarium specimens and literary sources. The herbarium studies, supplemented with targeted field search in the years 2015–2018, revealed 61 new localities and confirmed many other older locations. The species has been recorded in 19 phytogeographical districts and sub-districts of Slovakia. Most of the records are concentrated in the Podunajská nížina lowland in SW Slovakia and in the Ipel'sko-rimavská brázda region in southern Slovakia. Our results showed that the species is relatively common in different types of wetlands and its re-evaluation in the recent version of the Slovak red list is not needed. Chromosome number data for two new populations in eastern Slovakia (both 2n = 18) were counted. The distribution map is given.

Abstract Background: The internal transcribed spacer (ITS) of nuclear ribosomal DNA is one of the most commonly used DNA markers in plant phylogenetic and DNA barcoding analyses, and it has been recommended as a core plant DNA barcode. To compare and find out the analysis genetic diversity difference some pepper individuals collected in different localities in Vietnam when using the ITS of nuclear ribosomal DNA. The ITS gene region from the nuclear genomes were tested for their suitability as DNA barcoding regions of thirty-nine pepper individuals. Universal primers were used, and sequenced products were analyzed using the Maximum Likelihood method and Tamura-Nei model in the MEGA X program.Results: We did not observe high variability in intraspecific distance within the ITSu1-4 gene region between individuals, ranged from 0.000 to 0.155 (mean = 0.033). The size of the gene region has fluctuated from 667 to 685 bp between different individuals with the percentage (G + C) contained in the ITSu1-4 gene region was ranged from 54.776% to 60.805%, mean = 60.174%. The values of Fu’s Fs, D, Fu and Li’s D* and F* were negative as well (Fs = -0.209, D = -1.824; P < 0.05, D* = -1.205; not significant, P > 0.10 and F* = -1.699; not significant, 0.10 > P > 0.05), indicating an excess of recently derived haplotypes and suggesting that either population expansion or background selection has occurred. The value Strobeck’s S the obtained between individuals in a population is high (S = 0.684). The results of evolutionary relationships of taxa obtained 3 groups with the highest value of Fst is shown in the pairs of groups II and III (Fst = 0.151), and the lowest is in groups II and I (Fst = 0.015). All of the new sequences have been deposited in GeneBank under the following accession numbers MZ636718 to MZ636756.Conclusions: This database is an important resource for researchers working on Species of pepper in Vietnam and also provides a tool to create ITSu1-4 databases for any given taxonomy.

New localities of <em>Hygrocybe salicis-herbaceae</em> were observed during the research on the fungi of the alpine zone in the Carpathians. This is the first record of this arctic-alpine fungus in the South-Eastern Carpathians. Macro- and micromorphological characters of the Carpathian collections are compared with the descriptions from other regions. A revision of literature data indicates that the sites in the Parâng Mts. reported here are the only known localities of the species from the entire Carpathian range.

The historical archaeologist has various means to date artifacts. Stratigraphic comparisons, manufacturing techniques, as well as historical and comparative studies, enable the researcher to obtain dates of production for the objects for which dates are sought. However, artifacts unearthed from upper strata on historical sites are sometime dismissed as "modern", and left undated. These objects are readily recognized as twentieth century artifacts, and archaeologists seem content with this broad chronological identification. In certain contexts, however, there exists a need to obtain a solid chronology for finds produced during this century. In this paper, the author presents two episodes based on his experience on Canadian historic sites, where well dated twentieth century objects proved to be important chronological indicators. The artifacts were dated using Rural/oral history and company records. Finally, it is hoped that this article will indicate that twentieth century artifacts are worthy of equal analytical treatment as their earlier counterparts.

AbstractWe report the first detection of Fall Armyworm (FAW), Spodoptera frugiperda (Smith, 1797), in Bhutan. FAW feeds on more than 300 plant species and is a serious pest of many. It has been spreading through Africa since 2016 and Asia since 2018. In Bhutan, this species was first detected in maize fields in the western part of the country in September 2019 and subsequently found infesting maize crop in southern parts of the country in December 2019 and April 2020. Using morphological and molecular techniques the presence of the first invading populations of S. frugiperda in Bhutan is confirmed through this study. We present an updated reference DNA barcode data set for FAW comprising 374 sequences, which can be used to reliably identify this serious pest species, and discuss some of the reasons why such compiled reference data sets are necessary, despite the publicly availability of the underlying data. We also report on a second armyworm species, the Northern Armyworm, Mythimna separata (Walker, 1865), in rice, maize and other crops in eighteen districts of Bhutan.

Population decline is a process, yet estimates of current extinction rates often consider just the final step of that process by counting numbers of species lost in historical times. This neglects the increased extinction risk that affects a large proportion of species, and consequently underestimates the effective extinction rate. Here, we model observed trajectories through IUCN Red List extinction risk categories for all bird species globally over 28 years, and estimate an overall effective extinction rate of 2.17 × 10 −4 /species/year. This is six times higher than the rate of outright extinction since 1500, as a consequence of the large number of species whose status is deteriorating. We very conservatively estimate that global conservation efforts have reduced the effective extinction rate by 40%, but mostly through preventing critically endangered species from going extinct rather than by preventing species at low risk from moving into higher-risk categories. Our findings suggest that extinction risk in birds is accumulating much more than previously appreciated, but would be even greater without conservation efforts.

A comprehensive treatment of Ordovician crinoids from southwestern Europe is presented, including taxa based on articulated crowns and stems. This summary incorporates new material, new localities, and a revision of some southwestern Europe occurrences. The first record of an Ordovician crinoid from Portugal, Delgadocrinus oportovinum n. gen. and sp., is reported, and this is the oldest known crinoid from the Iberian Peninsula (Arenigian/Oretanian boundary, early Darriwilian). Geographic and temporal ranges of several crinoids are revised from peri-Gondwanan areas in southwestern Europe and northern Africa or modified with new Iberian material. The Spanish range of Heviacrinus melendezi Gil Cid et al., 1996 is extended down into the lower upper Oretanian, and Merocrinus millanae Ausich et al., 2002 is restricted to the upper lower Dobrotivian. The stratigraphic position of Ortsaecrinus cocae Gil Cid et al., 1999b is restricted to the early middle Berounian, and the range of Visocrinus castelli Ausich et al., 2002 is restricted to the late middle Berounian (see Fig. 2). New topotype material of Morenacrinus silvani Ausich et al., 2002 is reported that furthers understanding of the occurrence this taxon, which was previously only positively known from the holotype.
