Latitudinal variation in the asynchrony of seasons: implications for higher rates of population differentiation and speciation in the tropics

Speciation rates for some taxa increase from the poles towards the equator, augmenting the number of species in the tropics.The causes of latitudinal variation in speciation rates are presently unknown.Here we present and discuss the Asynchrony of Seasons Hypothesis that invokes latitudinal differences in the spatial asynchrony of climate, and the

A study on fault recovery method of TTDP backbone network node

Due to the mechanism of the TTDP (Train Topology Discovery Protocol), network nodes cannot meet the application requirements of all fault recovery scenarios in the status of inauguration inhibition, including multi-node fault recovery scenarios when multiple intermediate nodes are lost or one end node is included in multiple lost adjacent nodes.The

Effects of Dietary Brewery Spent Grain Inclusion on Egg Laying Performance and Quality Parameters of Bovans Brown Chickens

ABSTRACT Poultry rations are composed mainly of conventional cereal grains and proteins.Using non-conventional agro-industrial by-products may reduce the cost of production and thereby improve productivity.A study was conducted to evaluate the effect of dietary brewery spent grain inclusion on egg laying performance, quality parameters of bovans br
