Conservation value of an exotic species: the case of coconuts on the Kayapo indigenous lands, south-eastern Amazonia

Earthworms in the family Lumbricidae in Alaska, which are known from coastal regions, primarily in south-central and south-eastern Alaska, are thought to be entirely non-native and have been shown to negatively impact previously earthworm-free ecosystems in study regions outside of Alaska. Despite occasional collections by curious citizens, there had not been a standardised earthworm survey performed in Interior Alaska and no published records exist of earthworms species from this region. Mustard extraction was used to sample six locations that differed in elevation, mostly in the College region of Fairbanks, Alaska. Two of the six locations yielded earthworms. There was no relationship between earthworm abundance and elevation (p = 0.087), although our sample size was small. Our sampling, combined with specimens in the University of Alaska Museum, has documented four exotic species and one presumed native species of lumbricid earthworms in Interior Alaska.

Carex disperma Dewey reaches its south-eastern range limit in north-eastern Poland. It has often been confused with Carex loliacea L. In this paper the diagnostic features of both species are presented. A total of about 47 reliable localities of C. disperma were recorded within the present borders of Poland. Less than one-third of them have only been confirmed recently. They are aggregated in large forest complexes in north-eastern Poland (Romincka, Białowieża, Borki, Augustów and Knyszyn Forests). A list of localities of C. disperma based on herbarium records, credible literature data and the author's own data is provided, as well as maps of distribution of both C. disperma and C. loliacea in Poland. The existence of C. disperma × C. loliacea hybrid was not confirmed. Considering the number of localities, dynamics and population sizes of both species it is clear that C. disperma is a species with higher conservation value than C. loliacea. Unlike C. disperma, the latter species is not threatened with extinction in Poland. The resources of C. disperma are very limited and the species needs conservation measures such as creating sufficiently large nature reserves where appropriate hydrological conditions can be maintained.

Single Genus

The D’Aguilar Range of subtropical south-eastern Queensland (Australia), harbours an upland rainforest biota characterised by high levels of endemic diversity. Following recent phylogenetic and biogeographic research into the open-holed trapdoor spiders of the genus Namea Raven, 1984 (family Anamidae), remarkable levels of sympatry for a single genus of mygalomorph spiders were recorded from the D’Aguilar Range. It is now known that eight different species in the genus can be found in the D’Aguilar uplands, with five apparently endemic to rainforest habitats. In this paper we present a phylogenetic and taxonomic synopsis of the remarkable anamid fauna of the D’Aguilar Range: a key to the eight species is provided, and four new species of Namea are described (N. gloriosa sp. nov., N. gowardae sp. nov., N. nebo sp. nov. and N. nigritarsus sp. nov.). In shining a spotlight on the mygalomorph spiders of this region, we highlight the D’Aguilar Range as a hotspot of subtropical rainforest diversity, and an area of considerable conservation value.

Côte D'ivoire

The Tanoe-Ehy Forest, located in the South-Eastern of the Côte d’Ivoire is one of the rare forest cover of this type that still exists in the Country. These Forest was identified as a top priority site for conservation in West Africa. However, this important forest is subject to strong anthropogenic pressures which through poaching, uncontrolled takeoffs of natural resources and some agricultural clearing. A Botanical study based on plots, itinerant and linear inventory conducted in this forest intends to assess the plant species diversity and the conservation value for biodiversity of this forest. At the end of the study, 432 plant species were recorded. Among them, 14 are listed on endemic of Upper Guinea and 16 threatened and endangered list of species. Concerning the species threatened and endangering, 3 species are really in endangering (Hemandradenia chevalieri, Tieghemella heckelii, Irvingia gabonensis) and 13 others are a category of vulnerable species. A Sassandrian species of type II (Piptostigma fugax) was also observed. The dominant species of the forest are Symphonia globulifera and Uapaca paludosa. Concerning the vegetation condition, the swamp forest, the dry land forest and the raphiale vegetation have a high conservation value.
