Song in songbirds is widely thought to function in mate choice and male–male competition. Song is also phenotypically plastic and typically learned from local adults; therefore, it varies across geographical space and can serve as a cue for an individual’s location of origin, with females commonly preferring males from their respective location. Geographical variation in song dialect may reflec...
The processes of natural reforestation play a crucial role for the preservation primary coniferous forests and success their restoration after catastrophic impacts. objective our research was to identify features renewal main forest-forming plants under canopy stands in mountains Middle Urals, establish dependencies on forest type not only total number tree saplings, but also its age structure....
Aim Adaptation, migration and extinction of species is closely associated with climate changes shape the distribution biodiversity. The adaptive responses in biodiversity hotspot, Hengduan Mountains, to change remain poorly understood. Location southeast Qinghai-Tibet Plateau. Methods principles phylogeography landscape genomics were applied endemic Roscoea humeana Mountains by genotyping seque...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
abstract background: stroke is a stressful event with several functional, physical, psychological, social, and economic problems that affect individuals’ different living balances. with coping strategies, patients try to control these problems and return to their natural life. the aim of this study is to investigate the effect of a care plan based on roy adaptation model biological dimension on...
the strategies to reduce the consumption of non-renewable energies in buildings are becoming increasingly important. in the meantime, nature-inspired approaches have emerged as a new strategy to achieve thermal comfort in the interiors. however, the use of these approaches in architecture and buildings requires a proper understanding regarding the features of ecosystems. although acquiring this...
â â background eosinophilic gastroenteritis (eg) is a rare inflammatory disorder of the gastrointestinal (gi) tract. there have been several case series of patients with eg from the western world and east asia. however, there has not been a report of patients with eg from the middle east region. the aim of this study is to describe clinical characteristics and treatment response in a series o...
A high efficiency frequency doubler is realized based on a single embedded gate (EG) graphene field effect transistor (GFET) with natural Al oxidation dielectrics. Due to elimination of the step of depositing gate dielectrics, the fabrication process of the EG-GFET is improved compared to conventional EG-GFETs. The capacitive efficiency of the EG-GFET is improved up to 80 times compared to the ...
For centuries, islands and mountains have incited the interest of naturalists, evolutionary biologists ecologists. Islands been cradle for biogeography speciation theories, while mountain ranges informed how population adaptation to thermal floors shapes distribution species globally. varying size mountains’ altitudinal constitute unique “natural laboratories” where one can investigate effects ...
