A cave population of Isbrueckerichthys alipionis (Gosline, 1947) in the Upper Ribeira karst area, southeastern Brazil (Siluriformes: Loricariidae) Neotropical Ichthyology
Trajano,Eleonora; Secutti,Sandro; Pereira,Edson H. L.; Reis,Roberto E..
A cave population of the armored catfish Isbrueckerichthys alipionis is reported from the Santana Cave, in the rio Betari watershed, Upper Ribeira karst area, Iporanga, São Paulo State, southeastern Brazil. The cave population was compared to an epigean population of I. alipionis and no significant differences where found in morphology or degree of pigmentation. As the cave population is known for at least 30 years and is apparently isolated from epigean streams, it is classified as troglophilic. The discovery of this troglophilic species in the Santana Cave is an additional strong argument for the conservation of that cave.

A conservation genetic study of Rafflesia speciosa (Rafflesiaceae): patterns of genetic diversity and differentiation within and between islands Naturalis
Pelser, P.B.; Nickrent, D.L.; Barcelona, J.F..
Rafflesia speciosa is a threatened endo-holoparasitic species. It has several populations in the Central Panay Mountain Range (CPMR) of Panay island and a single population on Negros Island. Because R. speciosa is the only Philippine species of the genus that is not endemic to an individual island, it is a suitable species for improving our understanding of the factors underlying the high island endemism of Philippine Rafflesia. For this purpose and to inform the conservation management of R. speciosa, patterns of genetic diversity and differentiation were studied using 15 microsatellite loci and samples from nine populations. None of these populations shows evidence of inbreeding and R. speciosa has similar levels of heterozygosity as generally observed...

A conservationist approach on environmental diagnosis of ground use in the Iguatemi river basin, Mato Grosso do Sul State, Brazil - doi: 10.4025/actascibiolsci.v34i3.9001 Biological Sciences
Souto, Marco Antonio Gomes; Instituto Reserva Natural.
Landscape Ecology is a contemporary approach in conservation studies in which, coupled to the development and use of GIS-based tools, provides new methods for the analysis of forest fragments. Based on these new approaches, the environmental assessment of ground use in the Iguatemi river basin Mato Grosso do Sul State, Brazil is provided through conservation-based flora and ecology aspects. A regional map of ground use with field-collected data using Rapid Ecological Assessment methodology and digital satellite images was prepared. AER analysis showed a highly impacted region featuring intense transformation in ground use with a conversion of 87% of native forest into grazing and agriculture land. The general situation is inconsistent with APA guidelines,...

A Linnaeus NGTM interactive key to the Lithocolletinae of North-West Europe aimed at accelerating the accumulation of reliable biodiversity data (Lepidoptera, Gracillariidae) Naturalis
Doorenweerd, C.; Haren, M.M. van; Schermer, M.; Pieterse, S.; Nieukerken, E.J. van.
We present an interactive key that is available online through any web browser without the need to install any additional software, making it an easily accessible tool for the larger public. The key can be found at http://identify.naturalis.nl/lithocolletinae. The key includes all 86 North-West European Lithocolletinae, a subfamily of smaller moths (“micro-moths”) that is commonly not treated in field guides. The user can input data on several external morphological character systems in addition to distribution, host plant and even characteristics of the larval feeding traces to reach an identification. We expect that this will enable more people to contribute with reliable observation data on this group of moths and alleviate the work-load of taxonomic...

We present a new method for ecologically sustainable land use planning within multiple land use schemes. Our aims were (1) to develop a method that can be used to locate important areas based on their ecological values; (2) to evaluate the quality, quantity, availability, and usability of existing ecological data sets; and (3) to demonstrate the use of the method in Eastern Finland, where there are requirements for the simultaneous development of nature conservation, tourism, and recreation. We compiled all available ecological data sets from the study area, complemented the missing data using habitat suitability modeling, calculated the total ecological score (TES) for each 1 ha grid cell in the study area, and finally, demonstrated the use of TES in...

A Near-extinction Event in Lynx: Do Microsatellite Data Tell the Tale? Ecology and Society
Spong, Goran; Evolutionary Biology Centre, Uppsala University; goran.spong@ebc.uu.se; Hellborg, Linda; Evolutionary Biology Centre, Uppsala University; linda.hellborg@ebc.uu.se.
Fluctuations in population size can have a profound impact on effective population size and the maintenance of genetic variation within a population. A number of tests based on microsatellite data have been developed for the detection of bottleneck events in a population's past. In this paper, we search for signs of a bottleneck in microsatellite data on the Scandinavian lynx (Lynx lynx) population. This population was hunted to the brink of extinction, with fewer than 100 animals (one estimate was as low as 30 individuals) remaining in the late 1920s. Protection allowed recovery of the population, which currently numbers about 2000 adults. Despite this pronounced demographic bottleneck (more than 95% of the population was killed), we could find no...

A new species of Afrothismia (Burmanniaceae; tribe: Thismieae) from the western foothills of Mount Cameroon Naturalis
Franke, Th.; Sainge, M.N.; Agerer, R..
Afrothismia foertheriana, a new species of Burmanniaceae (tribe: Thismieae) from the peripheral zone of the Onge Forest Reserve in Cameroon’s Southwest Province is described and illustrated. The papillose, multicellular floral trichomes, the tepal’s erose margins, the small, zygomorphic perianth mouth and the dull purplish brown coloration give A. foertheriana a distinctive appearance within the genus. The species is here assessed as being critically endangered.

A note on the performance measure of conservation auctions AgEcon
Latacz-Lohmann, Uwe; Schilizzi, Steven.
We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

A preliminary revision of knowledge status of felids in Argentina Mastozool. neotrop.
Lucherini,Mauro; Soler,Lucía; Luengos Vidal,Estela.
Argentina is the host of 10 wild felids (28% of the world total). Although the Cat Specialist Group Action Plan has classified the conservation status of Argentine cats as relatively good, the ranking was based on a largely incomplete database for at least 80% of the species. Here we review the current status of knowledge and research effort of Argentine cats, compare it with their distribution, habitat association and conservation status and provide guidelines for their future research. Between 1990 and 2000, cat research has received increasing attention in Argentina. Twenty-four projects have been carried out, but only 13 studies are still in progress. A rank of research priority has been calculated for each felid and ecoregion. Our analysis showed that...

A synoptic revision of Inversodicraea (Podostemaceae) Naturalis
Cheek, M.; Feika, A.; Lebbie, A.; Goyder, D.; Tchiengue, B.; Sene, O.; Tchouto, P.; Burgt, X. van der.
Six new species of Inversodicraea (I. feika from Sierra Leone, I. liberia from Liberia, and I. ebo, I. eladii, I. tchoutoi, and I. xanderi from Cameroon) are described as new to science in the context of a synoptic revision of this African genus, now comprising 30 species, including I. cussetiana comb. nov., newly transferred from Macropodiella. Inversodicraea is now equal in number of species to Ledermanniella (as redefined), as the largest genus of the family in Africa. Terete or slightly dorsiventrally flattened leaf petioles (not sheathing and/or stipulate) are newly discovered to distinguish the genus from Ledermanniella, in addition to the presence of scale-leaves. Inversodicraea boumiensis, I. annithomae, and I. bosii are redelimited in this paper....

A troglomorphic spider from Java (Araneae, Ctenidae, Amauropelma) Naturalis
Miller, J.; Rahmadi, C..
A new troglomorphic spider from caves in Central Java, Indonesia, is described and placed in the ctenid genus Amauropelma Raven, Stumkat & Gray, until now containing only species from Queensland, Australia. Only juveniles and mature females of the new species are known. We give our reasons for placing the new species in Amauropelma, discuss conflicting characters, and make predictions about the morphology of the as yet undiscovered male that will test our taxonomic hypothesis. The description includes DNA barcode sequence data.

Abundance and length structure of Brycon nattereri (Osteichthyes, Bryconidae), an endangered fish species in central Brazil Biological Sciences
Vitorino Júnior, Oscar Barroso; Lopes, Kelven Stella; Pelicice, Fernando Mayer.
Brycon nattereri is a threatened fish species restricted to small headwater rivers of the Paraná, São Francisco and Tocantins rivers. This species has been extirpated from many sites, and little is known about its ecology. In this sense, the present study investigated temporal variations in the occurrence, abundance and length structure of B. nattereri in the Dois Irmãos river, a small headwater river from the Tocantins river basin. Samples were taken monthly between January and November of 2009 and 2010. The studied site comprised a 4.5 km river stretch, sampled with an active fishing method (fly fishing). Individuals caught were counted, measured and returned immediately to the river. We caught 302 individuals along two years. Brycon nattereri was...

Acceso, uso y conservación del recurso bosque, por mujeres en San Isidro Buen Suceso, Tlaxcala. Colegio de Postgraduados
Romo Evaristo, Marisol.
En la actualidad la situación de degradación de los recursos naturales, en especial el recurso bosque, ocasiona la pérdida tanto de identidad de la población que dependen de estos recursos, como de la misma flora y fauna del lugar, además que la introducción de la tecnología moderna y las formas de producción añadidos con el consumismo, han favorecido la destrucción del ambiente natural, siendo la sociedad humana una de las principales causas de dicha degradación. Aunado a ello, desde los 80s, se enfatizó que las mujeres fueron las principales víctimas del deterioro ambiental, además de catalogarlas como adaptadas para soportar catástrofes como las sequias, y se consideraban víctimas del deterioro ambiental, de los procesos científicos y de desarrollo mal...
