Population and species neighbor identity impact trait–trait relationships and plant performance

Population Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Study of astrophysically important resonant states in 30 S using the 32S(p,t)30 S reaction

EPJ Web of Conferences, 2010
A small fraction (< 1%) of presolar SiC grains is suggested to have been formed in the ejecta of classical novae. The 29P(p,γ)30S reaction plays an important role in understanding the Si isotopic abundances in such grains, which in turn provide us ...

mRNA bound to the 30S subunit is a HigB toxin substrate

RNA: A publication of the RNA Society, 2016
Activation of bacterial toxins during stress results in cleavage of mRNAs in the context of the ribosome. These toxins are thought to function as global translational inhibitors yet recent studies suggest each may have distinct mRNA specificities that ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Experimental investigation of the 30S(α, p) thermonuclear reaction in x-ray bursts

EPJ Web of Conferences, 2016
We performed the first measurement of 30S+α resonant elastic scattering to experimentally examine the 30S(α, p) stellar reaction rate in type I x-ray bursts.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Evaluation of Tipping, Rotation and rate of space Closure Rate of Canine Retraction by friction less orthodontic techniques (An In vitro Study) [PDF]

Al-Rafidain Dental Journal, 2006
Aim: To evaluate the effect of loops geometry (design) on the rate of space closure, degree of rotation, and degree of tipping. Materials and Methods: The sample consisted of 8 type of loops, namely vertical–loop, vertical with helix–loop, T–loop ...

In your 20s it's quantity, in your 30s it's quality: the prognostic value of social activity across 30 years of adulthood.

Psychology and Aging, 2015
Social connection, a leading factor in the promotion of health, well-being, and longevity, requires social knowledge and the capacity to cultivate intimacy. Life span development theorists have speculated that social information-seeking goals, emphasized

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
