Two new coffinfishes, Chaunax nebulosus n. sp. and Chaunax africanus n. sp., are described from the Indian Ocean. Both species belong to the C.fimbriatus-species group which is characterised by having filaments on the dorsal head and a complex color pattern on the dorsal surface. They are morphometrically and meristically conservative but differ in coloration. Chaunax nebulosus can be distingui...

Inbreeding, which is common in plants, may increase the vulnerability of populations to natural enemies. Similarly, natural enemies may increase the expression of inbreeding depression in their hosts, resulting in altered selection on host mating-system evolution. To examine effects of inbreeding on tolerance to herbivory, we transplanted experimentally selfand cross-fertilized plants into four...

Mahanarva fi mbriolata (Stål) is an important pest in Latin America and causes signifi cant reduction in sugarcane productivity. There is no information regarding the effect of this pest on the quality of cane juice used for sugar and alcohol production. This work aimed at evaluating the quality of sugarcane juice from plants attacked by spittlebugs. The experiment was arranged in a completely ...

The present study compares the mitochondrial genomes of five species of the spittlebug tribe Callitettixini (Hemiptera: Cercopoidea: Cercopidae) from eastern Asia. All genomes of the five species sequenced are circular double-stranded DNA molecules and range from 15,222 to 15,637 bp in length. They contain 22 tRNA genes, 13 protein coding genes (PCGs) and 2 rRNA genes and share the putative anc...

Abstract The validation of many anuran species is based on a strictly descriptive, morphological analysis small number specimens with limited geographic distribution. Scinax Wagler, 1830 genus controversial group doubtful taxa and taxonomic uncertainties, due high cryptic species. One example the pair constrictus nebulosus, which share similar morphology. restricted to Brazilian Cerrado savanna...

The spittlebugs Mahanarva spectabilis economically challenges cattle production of neotropical regions, due to its voracious feeding on tropical grasses. Here, we evaluated biochemical responses the interaction between M. and widely cultivated grasses Brachiaria spp. (i.e., brizantha decumbens) elephant (cvs. Roxo de Botucatu Pioneiro), regarding lipoxygenases, protease inhibitors, phytohormone...

Emerging evidence increasingly illustrates the importance of a holistic, rather than taxon-specific, approach to the study of ecological communities. Considerable resources are expended to manage both introduced and native mammalian carnivores to improve conservation outcomes; however, management can result in unforeseen and sometimes catastrophic outcomes. Varanid lizards are likely to be apex...
