Chrysomelinae is one of the largest subfamilies in Chrysomelidae, yet much basic information remains unknown for Neotropical species. The present study aims to compile the first regional list of Chrysomelinae for the State of Rio de Janeiro, Brazil, and assemble natural history traits obtained from our fieldwork from 2005 to 2010 in Serra dos Órgãos National Park, a mountainous area of Atlantic...

For sessile marine invertebrates, processes contributing to larval release, dispersal, and settlement in favourable habitats are central to patterns of distribution and community structure. We quantified larval release patterns, phototactic behaviour, and settlement in response to environmental cues for the coral reef sponge Luffariella variabilis. Individual sponges released up to 830 larvae d...

چکیده بر اساس مطالعات انجام شده در فصول زراعی 1386 و 1387، بعضی از جنبه های زیستی کرم ساقه خوار برنج (chilo suppressalis walker) شامل تعداد سنین لاروی و طول دوره ی رشد و نمو مراحل مختلف زیستی در دو نسل در منطقه ی مازندران بررسی شد. نتایج پژوهش حاضر نشان داد که تعداد سنین لاروی کرم ساقه خوار برنج در نسل های اول و دوم متفاوت می باشد، به طوری که این حشره در نسل اول دارای 6 و در نسل دوم دارای 5 سن ...

Soil moisture is critical parameters in climatic and hydrological modeling and vegetation growth. Ground-based point measurement of soil moisture is liable but expensive and impractical for watershed measurement. Remote sensing measurement has provided thriving perspective for spatial and instantaneous measurement of soil moisture. Microwave measurement is effective and successful for surface s...

The importance of spatial variability of antecedent soil moisture conditions on runoff response is widely acknowledged in hillslope hydrology. Using a distributed hydrologic model, this paper aims at investigating the effects of soil moisture spatial variability on runoff in various field conditions and at finding the structure of the soil moisture pattern that approaches the measured soil mois...

Multiple soil moisture products have been generated from data acquired by satellite. However, these satellite soil moisture products are not spatially or temporally complete, primarily due to track changes, radio-frequency interference, dense vegetation, and frozen soil. These deficiencies limit the application of soil moisture in land surface process simulation, climatic modeling, and global c...

searching efficiency (a') (attack rate) and handling time are two major components of natural enemies’ functional response and are usually used to evaluate their effectiveness. the age-specific searching efficiency of aphidoletes aphidimyza (rondani) was studied during its larval stage. the experiment was conducted in terms of age-specific functional response to the varying density (5, 1...

The presence of Hermetia illucens larvae in waste management systems is very beneficial because their ability to degrade waste. growth depends on the adequacy nutrients contained media such as protein and fat. purpose this study was determine growth, density nutritional correlation pineapple rice bran larvae. used a completely randomized design consisting 5 treatments, namely: 1) 100% waste; 2)...
