A specimen of Stactobia eatoniella, a hygropetric species of micro-caddisfly considered extinct in Switzerland, was discovered in the Morge in Valais in March 2020 during routine monitoring. This last instar larva in perfect condition is the first to be observed in Switzerland since 1944. Further research in the study area is needed to confirm the presence of a possible well-established population. This encouraging discovery should not hide the fact that two thirds of the micro-caddisfly species are on the Red List of threatened species of Switzerland, and that hygropetric habitats are both under-studied and highly endangered in Switzerland and worldwide.

Definition Of

In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.

Given the economic and cultural dependence on the marine environment in Oceania and a rapidly expanding human population, many marine species populations are in decline and may be vulnerable to extinction from a number of local and regional threats. IUCN Red List assessments, a widely used system for quantifying threats to species and assessing species extinction risk, have been completed for 1190 marine species in Oceania to date, including all known species of corals, mangroves, seagrasses, sea snakes, marine mammals, sea birds, sea turtles, sharks, and rays present in Oceania, plus all species in five important perciform fish groups. Many of the species in these groups are threatened by the modification or destruction of coastal habitats, overfishing from direct or indirect exploitation, pollution, and other ecological or environmental changes associated with climate change. Spatial analyses of threatened species highlight priority areas for both site- and species-specific conservation action. Although increased knowledge and use of newly available IUCN Red List assessments for marine species can greatly improve conservation priorities for marine species in Oceania, many important fish groups are still in urgent need of assessment.

Abstract Cactaceae is one of the most threatened plant families, in part as a result of the illegal extraction of plants for ornamental use. However, reports of the seizure and reintroduction of cacti are scarce and do not include species of Melocactus, the genus of Cactaceae in Brazil that has the highest number of threatened species. The coroa-de-frade Melocactus violaceus is endemic to Brazil and categorized as Vulnerable on the IUCN Red List. We report the seizure of 37 individuals of coroa-de-frade extracted illegally from their natural habitat, the results of their reintroduction to Paulo César Vinha State Park, in Espírito Santo state, Brazil, and provide information for environmental monitoring agencies regarding how to proceed in seizure cases, with the goal of minimizing the impacts of this illegal practice on the species. After seizure, 25 individuals were cultivated in a greenhouse and 12 were reintroduced in restinga, the natural area of occurrence of the species. After 6 months, survival was 76% for those individuals cultivated in the greenhouse and 84% for those planted in restinga, showing that rapid reintroduction of species with ornamental appeal, preferentially in their natural habitat, can reduce the impacts of illegal extraction. This reintroduction protocol can be used by managers of conservation units, contributing to the maintenance of threatened cactus species in their natural habitat.

Collecting of Carabidae was conducted using pitfall traps at four sites. The first two sites (T1 + T2) were at the slope of Macošská stráň and the other two sites (T3 + T4) at the slope of Vilémovická stráň. The study was done in 2008 and 2009. At Macošská stráň in 2008, 21 species of Carabidae with the total number of 228 individuals were found and in 2009, 18 species of the total number of 116 specimens were collected. At Vilémovická stráň in 2008, 22 species of Carabidae with the total number of 1977 specimens were found and in 2009, 21 species of the total number of 623 specimens were caught. In terms of classification of relictness, Macošská stráň in 2008 was dominated by species of adaptable group A (60%), species of eurytop group (E) were represented by 35% and of relic group (R) by 5%. In 2009, the same representation of species of groups A and E (47%) were found and the species of group R were represented by 6%. Vilémovická stráň in 2008 was dominated by species of group A (52%), species of group E were represented by 43% and of group R by 5%. In 2009 also dominated species of group A (54%), species of group E were represented by 41% and of group R by 5%. In the studied area we reported four endangered species of Carabidae protected by Law (No. 395/1992 Coll.) as amended, these were Calosoma auropunctatum (critically endangered), Brachinus crepitans, Carabus ullrichii and Cicindela campestris (endangered) and two species listed under the Red List of Threatened Species of the Czech Republic (Veselý et al., 2005). One of the species is listed as vulnerable (Calosoma auropunctatum) and one as near endangered (Carabus cancellatus). Another significant species found on the monitored sites was Aptinus bombarda.

Limestone Quarry

In 2012, a research was conducted on Carabid beetles in the active limestone quarry of Mokrá-Horákov. Collections were carried out on quarry terraces and quarry edges using pitfall traps. A total of 37 species with a total number of 197 specimens were captured. The most abundant species was Cicindela sylvicola (34 specimens) which is protected under Decree No. 395/1992 Coll. as amended by Decree No. 175/2006 Coll., other detected species protected by this Decree included C. campestris (28 specimens) and Cylindera germanica (26 specimens) which also belongs to the category of vulnerable under the Red List of Threatened Species of the Czech Republic. The quarry is mostly settled by eurytopic species preferring open habitats. Species that require unshaded habitats and species indifferent to shading occurred especially on the quarry terraces and on its outskirts. Species of shaded habitats were not reported.

Records of spiders of the vineyard terraces from the vicinity of the villages Morkůvky and Mutěnice Jesličky (South Moravia, Czech Republic) are published in the presented work. Spiders were collected by pitfall traping during 30 April – 28 October 2011 and by day and night sweeping of herb vegetation in different dates of 2011. In total 2719 individuals were collected, and identified as 139 species of 23 families. Eighteen species listed in the Red List of threatened species in the Czech Republic were recorded. In vineyard terraces in the vicinity of Morkůvky, 12 threatened species (CR – 2 species, EN – 3 species, VU – 7 species) were found altogether. In the vineyard terraces at Mutěnice, we found 13 threatened spider species (CR – 2 species, EN – 6 species, VU – 5 species). The most significant findings are Alopecosa solitaria (Herman, 1879), Cheiracanthium pennyi O.P.-Cambridge, 1873; Dipoena coracina (C. L. Koch, 1837); Dysdera hungarica Kulczyński, 1897; Eresus kollari Rossi, 1846; Euryopis quinqueguttata Thorell, 1875; Sibianor tantulus (Simon, 1868) and Haplodrassus minor (O.P.-Cambridge, 1879). Besides of these threatened species, we discovered rich spectra of rare spiders related to the well preserved xeric grasslands. Our faunistic results indicate that artificial habitats, such as vineyard terraces, are important refuges for wide spectra of xerothermophilous spiders.
