Novos registros na distribuição geográfica de anuros na floresta com araucária e considerações sobre suas vocalizações

Estudos envolvendo análises bioacústicas têm possibilitado a identificação de espécies pertencentes a grupos complexos, bem como a descrição e diferenciação de espécies crípticas. Recorrendo a esta ferramenta e com o objetivo de aumentar o conhecimento sobre a composição de espécies de anfíbios em áreas de Floresta com Araucária, foram amostradas 11 áreas nos estados do Paraná e Santa Catarina. Os resultados ampliaram significativamente o conhecimento da distribuição geográfica de oito espécies de anfíbios anuros: Ischnocnema henselii, Dendropsophus anceps, atualmente classificada como criticamente ameaçada no Estado do Paraná, D. nahdereri, Scinax granulatus, Trachycephalus dibernardoi, Pseudis cardosoi, Leptodactylus araucaria e L. nanus. Alguns destes registros representam correções em identificações anteriores: Ischnocnema henselii é uma espécie críptica e algumas populações até o momento eram confundidas no Paraná com I. guentheri; Trachycephalus dibernardoi era identificada como T. imitatrix e Leptodactylus nanus como L. marmoratus. A caracterização e descrição dos cantos destas espécies também são apresentadas.Studies involving bioacoustics analysis turned possible the identification of complex species groups, as well as the description and differentiation of cryptic species. In order to increase the knowledge on the species composition of amphibians in Araucaria Forests, we sampled eleven areas in the states of Paraná and Santa Catarina, which significantly increased the geographic distribution range of eight amphibian species: Ischnocnema henselii, Dendropsophus anceps, a currently classified as critically endangered in Paraná State, D. nahdereri, Scinax granulatus, Trachycephalus dibernardoi, Pseudis cardosoi, Leptodactylus araucaria and L. nanus. Some of the new records represent corrections of previous identifications for example: Ischnocnema henselii is a cryptic species with some populations in Paraná that have been previously mistaken to I. guentheri; Trachycephalus dibernardoi was mistaken for T. imitatrix and Leptodactylus nanus to L. marmoratus. We also characterize and describe the calls of all these species.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Programa de Pós-graduação em Biologia AnimalUniversidade Federal de Goiás (UFG) Departamento de Ecologia Laboratório de Comportamento Animal e HerpetologiaUniversidade Federal do Acre Centro Multidisciplinar Laboratório de HerpetologiaStaatliches Museum für Naturkunde StuttgartUniversidade Tecnológica Federal do ParanáUniversidade Estadual Paulista Departamento de Zoologia e BotânicaUniversidade Estadual Paulista Programa de Pós-graduação em Biologia AnimalUniversidade Estadual Paulista Departamento de Zoologia e Botânic

The Amsterdam Declaration on Fungal Nomenclature

The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19–20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or changed now that molecular data are routinely available. The issue is urgent as mycologists currently follow different practices, and no consensus was achieved by a Special Committee appointed in 2005 by the International Botanical Congress to advise on the problem. The Declaration recognizes the need for an orderly transitition to a single-name nomenclatural system for all fungi, and to provide mechanisms to protect names that otherwise then become endangered. That is, meaning that priority should be given to the first described name, except where that is a younger name in general use when the first author to select a name of a pleomorphic monophyletic genus is to be followed, and suggests controversial cases are referred to a body, such as the ICTF, which will report to the Committee for Fungi. If appropriate, the ICTF could be mandated to promote the implementation of the Declaration. In addition, but not forming part of the Declaration, are reports of discussions held during the symposium on the governance of the nomenclature of fungi, and the naming of fungi known only from an environmental nucleic acid sequence in particular. Possible amendments to the Draft BioCode (2011) to allow for the needs of mycologists are suggested for further consideration, and a possible example of how a fungus only known from the environment might be described is presented

Recognising land rights for conservation tenure reforms in the Northern Sierra Madre, The Philippines

The legalisation of the customary land rights of rural communities is currently actively promoted as a strategy for conserving biodiversity. There is, however, little empirical information on the conservation outcomes of these tenure reforms. In this paper, we describe four conservation projects that specifically aimed to formalise land rights in the Philippines, a country widely seen as a model for the devolution of control over natural resources to rural communities. We demonstrate that these legalistic interventions are based on flawed assumptions, on: 1) the capacity of the state to enforce tenure; 2) the characteristics of customary land rights; and 3) the causal links between legal entitlements and sustainable natural resource management. As a result, these state-led tenure reforms actually aggravate tenure insecurity on the ground, and ultimately fail to improve natural resource management.FWN – Publicaties zonder aanstelling Universiteit Leide

What Is Genetic Diversity and Why Does it Matter?

Published: 09 December 2021All living things on Earth contain a unique code within them, called DNA. DNA is organised into genes, similar to the way letters are organised into words. Genes give our bodies instructions on how to function. However, the exact DNA code is dierent even between individuals within the same species. We call this genetic diversity. Genetic diversity causes differences in the shape of bird beaks, in the flavours of tomatoes, and even in the colour of your hair! Genetic diversity is important because it gives species a better chance of survival. However, genetic diversity can be lost when population get smaller and isolated, which decreases a species’ ability to adapt and survive. In this article, we explore the importance of genetic diversity, discuss how it is formed and maintained in wild populations, how it is lost and why that is dangerous, and what we can do to conserve it.Melissa Minter, Erica S.
