northern khorasan province is located in north-east iran. according to demarton coefficient, it is a semiarid region. arid and semi-arid or subhumid zones are characterized by temperature variations, low and erratic rainfall, periodic droughts and different associations of vegetative cover and soils. this article looks at current dry lands and general guidelines for finding the best area for dr...

The lowland rainforest of northeastern Costa Rica harbours an assemblage of large wandering spider species belonging to three habitat subguilds: (1) semi-aquatic, (2) forest ground dwelling and (3) vegetation dwelling. We hypothesized that desiccation resistance should differ among species preferring different microhabitats and the associated microclimate. Desiccation resistance was assessed by...

– The Toco Toucan (Ramphastos toco) is a large canopy frugivore common in the seasonal areas of the interior of Brazil. In this study, I evaluated fruit production and analyzed the toucan’s feeding habits in two types of dry forests, one deciduous, although rich in figs, and another semi-deciduous, both in the western Brazil. Both areas exhibited marked fruiting patterns, which peaks overlapped...

Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains. ey are major drivers of grassland productivity but can negatively a€ect plant diversity. Soil moisture is known to a€ect soil microbial activity and plant P nutrition but the e€ects of irrigation on soil P status, soil microbial P and plant P nutrition in semi-natural grasslands remain larg...

This paper presents a fully dry assembly method to obtain densely packed arrays of parts from 400-800μm in size. This approach shows promise for enabling formation of a module of n and p type materials optimized for micro scale thermoelectric cooling performance. INTRODUCTION Inertial force (mass of the assembled parts) plays a critical role for part alignment and orienting in a dry microassemb...

The dry forests of northeastern Brazil are found near the coastal zone and on low, isolated mountains inland amid semi-arid vegetation. The floristic composition of these dry montane forests, as well as their relationship to humid forests (Atlantic forest sensu stricto) and to the deciduous thorn woodlands (Caatinga sensu stricto) of the Brazilian northeast are not yet well known. This paper so...
