The taxonomic status of Hyla pulchella joaquini (Anura : Hylidae) with description of its tadpole and vocalization

We redescribe Hyla pulchella joaquini and describe its tadpole and vocalization. The taxonomic status of this subspecies is reevaluated; and on the basis of morphology, geographic distribution, and vocalization, we propose the elevation of this subspecies to specific level with the name Hyla joaquini B. Lutz 1968. We also discuss the relationship of H, joaquini within the species groups of H. pulchella Dumeril and Bibron 1841 and H. circumdata (Cope 1871).

The taxonomic status of Leptodactylus geminus Barrio, 1973

The advertisement calls of Leptodactylus geminus, Leptodactylus gracilis, Leptodactylus plaumanni, and Leptodactylus fuscus are analyzed and compared with published reports. Based on calling data and examination of type material, Leptodactylus geminus is synonymized with L, plaumanni. To differentiate between the sibling species L. gracilis and L. plaumanni, fieldwork is needed, including recording of advertisement calls. Reliable identification of red specimens is not possible based on morphology and coloration alone.

Metanotal gland of the genus Eidmanacris (Grylloidea, Phalangopsidae): taxonomic importance

O presente trabalho compara a glândula metanotal de cinco espécies do gênero Eidmanacris por meio de microscopia eletrônica de varredura: E. corumbatai Garcia, 1998, E. alboannulata (Piza, 1960), E. dissimilis Desutter-Grandcolas, 1995, E. larvaeformis (Chopard, 1938) e Eidmanacris sp. A configuração externa da glândula foi determinada pela presença de duas projeções medianas que apresentam abertura em seu ápice e um grupo de cerdas abaixo destas projeções. Apesar de haver um padrão geral semelhante, a configuração da glândula é espécie-específica, que pode ser definida principalmente pela organização de cerdas e pela posição das projeções medianas. Nossos resultados sugerem a importância taxonômica desta estrutura, que deveria ser melhor analisada na descrição de espécies do gênero Eidmanacris. Pela observação do comportamento reprodutivo destas espécies, nós concluímos que a liberação da secreção desta glândula é importante para o sucesso reprodutivo.

Size, taxonomic and biomass distributions of flying insects in Central Amazonia: Forest edge vs. understory

Significantly more individuals and biomass of flying insects were present at the forest edge than in the understory throughout the year, as monitored by flight interception traps, in Central Amazonia. Numbers and biomass of flying insects increased at higher rates at the edge with rainfall, associated with termite swarming behavior and increased Homopteran density. The most abundant insects were Diptera, Coleoptera, Hymenoptera and Isoptera, whose ranked abundances varied with respect to forest edge and understory, as well as with season.

Taxonomic status of the genus Sotalia: Species level ranking for tucuxi (Sotalia fluviatilis) and costero (Sotalia guianensis) dolphins

Dolphins of the genus Sotalia are found along the Caribbean and Atlantic coasts of Central and South America and in the Amazon River and most of its tributaries. At present, the taxonomy of these dolphins remains unresolved. Although five species were described in the late 1800s, only one species is recognized currently (Sotalia fluviatilis) with two ecotypes or subspecies, the coastal subspecies (Sotalia fluviatilis guianensis) and the riverine subspecies (Sotalia fluviatilis fluviatilis). Recent morphometric analyses, as well as mitochondrial DNA analysis, suggested recognition of each subspecies as separate species. Here we review the history of the classification of this genus and present new genetic evidence from ten nuclear and three mitochondrial genes supporting the elevation of each subspecies to the species level under the Genealogical/Lineage Concordance Species Concept and the criterion of irreversible divergence. We also review additional evidence for this taxonomic revision from previously published and unpublished genetic, morphological, and ecological studies. We propose the common name costero for the coastal species, Sotalia guianensis (Van Beneden 1864), and accept the previously proposed tucuxi dolphin, Sotalia fluviatilis (Gervais, 1853), for the riverine species.

A general survey and some taxonomic implications of diterpenes in the Asteraceae

This paper provides a general survey of the occurrence of diterpenes in the Asteraceae. Data on 4351 botanical occurrences were obtained from the literature. These were grouped by skeleton for each genus. Then, the genera were grouped by subtribes, which, in turn, were gathered in tribes, followed by subfamilies. In spite of the low number of species containing diterpenes, it was possible to describe some structural features of these compounds, i.e. The skeletal types in various taxa and the positions in some skeletons that are always oxidized or never undergo oxidation in some genera. Thus, it was verified that: in the subfamily Cichorioideae, only a few of the studied species possess diterpenes, wherein kaurane is the most frequent diterpene skeleton. In the Asteroideae, the presence of diterpenes is much greater than that in the Cichorioideae and Carduoideae. At tribal taxonomic level, for example, the Astereae produce labdanes and clerodanes; Heliantheae and Eupatorieae produce kauranes and labdanes, respectively; and Calenduleae produce pimaranes. Some taxonomic implications are presented. (c) 2005 the Linnean Society of London.
