Fisheries, life-history and conservation status of the catfish pirá Conorhynchos conirostris (Ostariophysi: Siluriformes) in Brazil Neotropical Ichthyology
Godinho,Alexandre Lima; Godinho,Hugo Pereira.
ABSTRACT Pirá, Conorhynchos conirostris (Valenciennes, 1840), a large migratory catfish endemic to the São Francisco River (SFR), is listed as threatened in the red lists of both Brazil and the state of Minas Gerais. Although fishing for pirá has been prohibited, it is still an important fishery resource, particularly in the middle SFR. We used historical and current occurrence and abundance data regarding pirá to determine if it meets the IUCN criteria of a threatened species. Pirá occurs in the main course of the SFR as well as in its major tributaries. Unlike the most well-known migratory fishes of the SFR, pirá does not use floodplain lakes as nurseries. In the first half of the 20th century, pirá occurred from the upper to the lower SFR. Currently, it...

Recent changes in distribution of dragonflies in Switzerland (Odonata) Naturalis
Gonseth, Y.; Monnerat, C..
Recent changes in distribution of dragonflies in Switzerland (Odonata) In 1998 the Swiss Centre for the Cartography of Fauna (CSCF) initiated ‘Odonata 2000’. This project aimed at testing a method for periodical reassessment of Red Lists in Switzerland. The study was carried out on Odonata and consisted of the resampling of known localities of threatened species and the sampling of new localities. Based on the number of sites where a given species has been found in the periods 1970-1998 and 1999-2000, trends were calculated for each species. The results show that since 1994 three species have disappeared from Switzerland, nine species have declined, two species have increased and 64 species have remained stable. Crocothemis erythraea, Lestes virens,...

Rediscovered after 77 years: Odontodiaptomus thomseni - a rare species of calanoid (Crustacea: Copepoda) from South America Rev. Bras. Zool.
Perbiche-Neves,Gilmar; Boxshall,Geoff A.; Rocha,Carlos E. F. da; Nogueira,Marcos G..
The freshwater copepod Odontodiaptomus thomseni (Brehm, 1933) (Calanoida: Diaptomidae) is a rare species that has been reported only once - in its original description (BREHM 1933). The lack of subsequent records led to its inclusion in the Red List of threatened species (IUCN). Here we present a new record for O.thomseni. It was discovered in Salto Grande reservoir, which is located in the lower stretches of the Uruguay River, between Uruguay and Argentina, at the River Plate basin. In January 2010, three specimens (two males and one female) were found, and these were studied in detail using scanning electron microscopy (SEM). We only had material of Odontodiaptomus paulistanus (Wright, 1936) for comparison, but the position of the lateral spine in right...

Stichelia pelotensis (Lepidoptera, Riodinidae): conservation, notes, and rediscovery of an endangered butterfly from southern Brazil Rev. Bras. entomol.
Siewert,Ricardo Russo; Gomes,Gustavo Crizel; Gallo,Mariana Centeno; Iserhard,Cristiano Agra.
ABSTRACT Stichelia pelotensis (Lepidoptera, Riodinidae) is an endemic and threatened butterfly from the Pampa biome in southern Brazil, and has not been recorded in its type locality in the last 56 years. Recently, a population was found in two sites from extreme south Brazil, Pelotas, Rio Grande do Sul state. These records are an important find given the conservation status of S. pelotensis, since all the information gathered is new and involve the natural history of this species. The information obtained is useful for the management, monitoring and conservation priorities of this species and its associated habitats, since its known distribution is restricted to a narrow area in the Rio Grande do Sul Coastal Plain inside this threatened biome in southern...

Threatened and Rare Ornamental Plants JARTS
Khoshbakht, Korous; Hammer, Karl.
The application of IUCN criteria and Red List Categories was done for ornamental plants. Main sources of the study were Glen’s book, Cultivated Plants of Southern Africa (Glen, 2002) and the Red List of Threatened Plants, IUCN (2001). About 500 threatened ornamental plants could be found and presented in respective lists. Rare ornamental plants with 209 species is the largest group followed by Vulnerable (147), Endangered (92), Indeterminate (37), Extinct (6) and finally Extinct/Endangered groups with 2 species. A weak positive correlation (r = +0.36 ) was found between the number of threatened species and the number of threatened ornamental species within the families.
