response surface models predict crop yield based on crop density and this is an important tool for evaluation competition at different density and hence selection of optimum density based on yield. in order to study intra and inter specific competition in intercropping bean (phaseolus vulgaris) and sesame (sesamum indicum), an experiment was conducted at the agricultural research station, ferdo...

A t-(v, k,;\) directed design (or simply a t-(v, k, ;\)DD) is a pair (V, B), where V is a v-set and B is a collection of (transitively) ordered k-tuples of distinct elements of V, such that every ordered t-tuple of distinct elements of V belongs to exactly). elements of B. (We say that at-tuple belongs to a k-tuple, if its components are contained in that k-tuple as a set, and they appear with ...

Nonhuman males attend to the number of potential sexual rivals in the local environment to assess sperm competition risk. Males of these species sometimes perform more frequent in-pair copulations to increase the likelihood of success in sperm competition. Here, we extend this research to humans, Homo sapiens. We secured self-report data from 393 men in a committed, sexual, heterosexual relatio...

Land surface temperature and fractional vegetation coverage (LST/FVC) space is a classical model for estimating evapotranspiration, soil moisture, and drought monitoring based on remote sensing. One of the key issues in its utilization is to determine its boundaries, i.e., the dry and wet edges. In this study, we revisited and compared three methods that were presented by Moran et al. (1994), L...

Most females mate with many males. This can be costly, but the benefits to females are often unclear. A new study raises the possibility that females could benefit through an unconventional genetic pathway, while also showing that males can inadvertently increase rival males' fitness in surprising ways.

The Darwin-Bateman paradigm recognizes competition among males for access to multiple mates as the main driver of sexual selection. Increasingly, however, females are also being found to benefit from multiple mating so that polyandry can generate competition among females for access to multiple males, and impose sexual selection on female traits that influence their mating success. Polyandry ca...

Semantic information is more likely to be retrieved from recognized faces than from recognized voices. Earlier studies which investigated the recall of biographical information following person recognition used famous people’s voices and faces. The present study was designed with the aim of controlling more strictly the exposure frequency to both domains of stimuli (voices and faces). Participa...

Climate change is a growing concern for society and the focus of numerous research initiatives across multiple fields of science. These initiatives often need to capitalize on the cross-specialized knowledge contributed by researchers from very different fields. The diversity of worldviews among key stakeholders requires an effective overall design strategy acting as a boundary spanner object. ...
