Flower Visiting

In the present paper we provide the first contribution to the knowledge of the flower-visiting insect assemblages of the alpine plant species Callianthemum kernerianum Freyn ex A. Kerner (Ranunculaceae). This focal plant species was selected since it is a steno-endemic and critically endangered species belonging to the IUCN red-list. Fifteen taxa were recorded, among which very few are true pollinators, whereas all the others can be considered only indirect pollinators. The peculiar phenology of the plant and the harsh habitat conditions in which it grows probably affect the richness and abundance of flower-visiting insects as well as of true pollinators. This could be the reason for this plant to be a self-compatible species.

Three species of chewing lice—Eucolpocephalum femorale (Piaget, 1880) (Amblycera: Menoponidae), Ibidoecus plataleae (Denny, 1842) (Ischnocera: Philopteridae) and Ardeicola plataleae (Linnaeus, 1758) (Ischnocera: Philopteridae)—are reported from the black-faced spoonbill (Platalea minor Temminck & Schlegel, 1849) in Japan. These three louse species are new records for this host. The black-faced spoonbill is classified as a “Critically Endangered” species in the IUCN Red List; although its species of lice are known to infest other species of spoonbills, these lice are endangered at the population level.

Abstract The paper presents a regional red list of vascular plant species native to the Western Suwałki Lakeland, north-eastern Poland, based on the IUCN red list categories and criteria. The distribution and abundance data were obtained from the field floristic inventories carried out in 2008- 2016 using the ATPOL cartogram method. The historical occurrences of vascular plant species were revised in the field. The list comprises 203 species, including seven regionally extinct species, 43 critically endangered species, 49 endangered species, 25 vulnerable species, 48 near threatened species, and 31 data deficient species. The results are compared to the Polish national red list of pteridophytes and flowering plants and briefly discussed.

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.

AbstractWenchengia alternifolia (Lamiaceae) is a plant species endemic to Hainan Island, China. Since the 1930s it was known from only four collections and was believed to be extinct until a remnant population was rediscovered in 2010. We conducted further field surveys during 2010–2012 but located only one population, with 66 individuals. W. alternifolia is restricted to the c. 1,500 m2 Shuangximu Valley, in a harsh microenvironment surrounded by plantations. As the population comprises < 50 mature individuals, we propose that W. alternifolia be categorized as Critically Endangered on the IUCN Red List, based on criterion D. We recommend that the remnant population and its habitat need urgent protection and monitoring and that ex situ conservation, for future reintroduction, should be implemented.

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.

We describe and illustrate two new species of Syngonanthus from Chapada dos Veadeiros (Central highlands of Brazil), an area known for its high number of endemic and threatened species, such as those described here. These species have a restricted distribution and inhabit critical areas. Syngonanthus incurvifolius has not been collected since 1994 and is critically endangered; Syngonanthus vittatus is known only from a small somewhat disturbed area, on private property, and is endangered. Evaluation of threatened status was provided by CNCFlora, the IUCN Red List Authority in Brazil.

Eugenia alletiana, a new endemic species from Mauritius, is described and its ecology and conservation is discussed. The morphological diagnostic features for Eugenia alletiana are chartaceous, discoloured leaves, very thin terminal branchlets, flowers solitary or in fascicles of 2–3 flowers, totally fused hypanthium without apical pore or calyptra, that encloses the numerous stamens (> 500) and petals before anthesis; seed enclosed in a woody endocarp with a lamellated outer surface. The species should be considered as Critically Endangered (CR) according to the Red List Criteria of the International Union for the Conservation of Nature. This assessment is based on the plant’s restricted distribution, very small population size, a habitat sustaining degradation by invasive alien plants and animals and predation of immature fruits and seeds by invasive alien monkeys and rats respectively leading to a weak regeneration.

Introduction: 1/4th of all plant species in the world are at risk of being endangered or going extinct. The IUCN Red List is a critical indicator of the health of the world’s biodiversity. It provides information about range, population size, habitat and ecology, use or trade, threats, and conservation actions that will help inform necessary conservation decisions. Hence the study was conducted to explore the status of plants of Udyavara village in IUCN red list of endangered species. Method: The Plant identification was carried in certain areas of Udyavara village by survey method. Authentication done by referring standard flora and experienced taxonomist. The enlisted drugs were studied for its status in IUCN red list. Result: The endangered plant species were explored from 276 identified plants of Udyavara village. Among them 80 evaluated species were identified with its category of endangered red list. Conclusion: The plants encountered under endangered species available in Udyavara Village of Udupi District will guide the practitioner for its judicial use in medicine. Moreover, the conservation of such plant species is possible by further cultivation of the same.

Extinction Risk Assessment

Background – Studies of neotropical Monimiaceae revealed a new species of Mollinedia endemic to the state of Espírito Santo, eastern Brazil. In this study, we describe, illustrate, and compare the new species with related taxa. In addition, ecological comments and extinction risk assessment of the new species are provided.Methods – This study was based on herbarium material and field work observations. The risk of extinction assessment follows the IUCN Red List of Threatened Species’ Criteria and Categories and the latest version of the IUCN Guidelines.Results – Mollinedia ruschii sp. nov. has habitat specificity with few individuals recorded, mainly in the Estação Biológica de Santa Lúcia, a protected area created by Augusto Ruschi, a Brazilian naturalist and researcher, to whom we dedicate the name of the new species. Phytosociological and forest dynamics studies and intensive field work in the area where the species occurs, enabled the detection of the decline of mature individuals in previous decades. Following the IUCN Red List criteria, the species is assessed as Critically Endangered.
