In order to simultaneously determine the values of total solar irradiance (TSI) and Earth’s radiation at top atmosphere (TOA) on board Fengyun-3F satellite, a spaceborne relative radiometer (SRR) was developed. It adopts dual-channel structure, including channel (SR) with an unobstructed field view (FOV) 1.5° Earth (ER) wide (WFOV) 95.3° diameter about 1900 km ground. Before launch, both SR ER ...

Web-spinning spiders that inhabit stream channels are considered specialists of aquatic ecosystems and are major consumers of emerging aquatic insects, while other spider taxa are more commonly found in riparian forests and as a result may consume more terrestrial insects. To determine if there was a difference in spider taxa abundance between riverine web-spinning spider assemblages within the...

Eutrophic estuaries receive organic matter (OM) inputs from multiple sources. This study evaluated the distribution and origin of sedimentary OM in an eutrophic estuary (Pina Sound, NE Brazil). Thirteen samples were collected sublittoral addition to major local Biochemical (chlorophyll - Chl), elemental [(C/N)a C/S ratios] isotopic (δ 15N δ 13C) analyses carried out for characterizing redox con...

This study presents one of the few known examples where a mysid species has been observed modifying its diet rapidly and under natural conditions in response to environmental changes. Mesopodopsis africana is a dominant mysid in many estuaries along the east coast of South Africa, and a key species in the St. Lucia Estuary, Africa’s largest estuarine lake. St. Lucia is currently undergoing seve...

Abstract This study investigates the trophic interactions and As Cd transfer along seven marine ecosystems in Peru. Five of these are driven by aquaculture Peruvian scallop Argopecten purpuratus . A southward increased gradient δ 15 N was observed among three examined regions coast. The stable isotope analysis R (SIAR)‐stable mixing models helped to clarify feeding ecology A. its important pred...

The aim of this study was to analyze the isotopic composition in muscle of striped weakfish Cynoscion guatucupa from Southwest Atlantic Ocean in order to evaluate a possible variation in δ13C and δ15N in response to dietary shifts that occur as animals grow. We also explored for isotopic evidence of differences between sample locations. The results showed an agreement between isotope analysis a...

Intraspecies dietary flexibility, such as variable consumption of graze vs. browse in herbivores, has received scant attention on a spatial scale despite growing evidence of substantial variability within and among populations, especially in bovids. Here, we report on extraordinary differences in cattle diet among two communal pasture areas across seasons in northern Namibia: King Nehale (KN, o...

Fry (2013; Mar Ecol Prog Ser 472:1−13) reviewed approaches to solving under determined stable isotope mixing systems, and presented a novel approach based on graphi cal summaries. He inaccurately characterized the statistics and interpretation of outputs from IsoSource and more recent Bayesian mixing model tools (e.g. SIAR, MixSIR), however, and as an alternative promoted an approach — not base...
