agricultural sustainability is closely related with the efficient use of natural resources, which are primarily transformed by the action of microorganisms. soil microorganisms are usually used as early indicators of soil quality since they rapidly respond to changes in soil management. a field experiment was carried out aiming to evaluate the effect of siratro (macroptylium atropurpureum), bah...

We review the basic patterns of complex non-uniqueness in simple discrete-time population dynamics models. We begin by studying a population dynamics model of a single species with a two-stage, two-habitat life cycle. We then explore in greater detail two ecological models describing host–macroparasite and host–parasitoid interspecific interactions. In general, several types of attractors, e.g....

People perceive similarity between their own personality characteristics and the of others. This association has sometimes been labeled assumed similarity, reflecting interpretation that it is a cognitive bias. Another possibility, however, an interpersonal path to perceived similarity: traits are manifested in behavior may elicit similar or dissimilar from others, people form perceptions based...

We consider the linear growth and fragmentation equation ∂ ∂t u(x, t) + ∂ ∂x ( τ(x)u ) + β(x)u = 2 ∫ ∞ x β(y)κ(x, y)u(y, t) dy, with general coefficients τ, β and κ. Under suitable conditions (see [17]), the first eigenvalue represents the asymptotic growth rate of solutions, also called the fitness or Malthus coefficient in population dynamics. This value is of crucial importance in understand...

Most accessibility studies focus on within transport mode travel performance variations. However, modal disparity analysis adds value to the single-mode by assessing interaction between different modes and land use. A review of shows that metrics lead results, so it is unclear how this impacts variation. Moreover, correspondence spatial pattern unclear. This research examines three typical (clo...

Change in maternal report of sibling negativity was investigated in 313 sibling dyads from 171 families taking part in a longitudinal, general population survey in the United Kingdom. The inclusion of multiple dyads per family allowed for the emergence of 3 novel elements for sibling research: an examination of within-family similarity on sibling relationship quality, modeling within-family sim...

Humpback whales have a continually evolving vocal sexual display, or "song," that appears to undergo both evolutionary and "revolutionary" change. All males within a population adhere to the current content and arrangement of the song. Populations within an ocean basin share similarities in their songs; this sharing is complex as multiple variations of the song (song types) may be present withi...

Genetic fine mapping can be performed by exploiting the notion that haplotypes that are structurally similar in the neighbourhood of a disease predisposing locus aremore likely to harbour the same susceptibility allele. Within the framework of Generalized Linear Mixed Models this can be formalized using spatial smoothing models, i.e. inducing a covariance structure for the haplotype risk parame...

In this paper we simulate the breeding process of marker-assisted introgressing a favorable QTL allele from “donor” to “recipient”. During this process, the foreground selection and background selection were made for introgression population simultaneously: foreground selection is making indirect selection of target gene by its closely linked two flanking markers, four selection methods includi...
