Diverse anthropogenic activities including alteration of hydrological regime and agricultural development in the upstream river catchments modify structural components ecological roles species estuarine ecosystems. The present study compared diet, carbon (?13C) nitrogen (?15N) isotopic signals, trophic niches metrics redundancy predatory fish their potential phytodetritivore prey-fish between t...

Silver pomfret (Pampus argenteus) performs a significant appetite for jellyfish, and amino acids are common components of the natural prey fish, so we investigated effect aspartic acid, glycine cysteine (high-content acid in jellyfish) on olfactory-related receptors regulating silver pomfret. The fish showed attractant responses to these water, which were also observed improve ingestion rates f...

Beek (2016) argued that Rubus aetnicus Cupani ex Weston was the correct name of taxon then called R. canescens DC., and which previously known as tomentosus Borkh. Moreover, stated to be not identical with aetnicus, but rather a form × collinus DC. Matzke-Hajek raised objections both statements. Therefore, aim this study thoroughly analyse names support analysis field work at type localities by...

Fishes of the tropical Indo-Pacific family Siganidae comprise 28 species, characterized by their body proportions and their colour patterns. A mitochondrial phylogeny of 20 Siganidae species was produced to infer their evolutionary history. Three distinct, major clades were found, that also correspond to the early radiation of the family into three major ecological types: fusiform species that ...

Abstract Context Tropical mountains are hotspots of plant diversity, with a remarkable density narrow ranged and endemic species. To develop effective in situ strategies for the conservation species under changing climatic conditions we need to understand mechanisms that shape their distributions. Objectives We explore how disturbance shapes elevation ranges two shrubs eight tree ( Hypericum ir...
