to evaluate the effect of bio-fertilizers on physiological traits in soybean under water deficit condition, agreenhouse experiment was conducted in 2011, at faculty of agriculture, tarbiat modares university,using a factorial design based on rcbd with three replications. the experimental treatments weredifferent irrigation regimes including non-stress (40% water depletion), moderate stress (60%...

OBJECTIVE Research on the strength model of self-regulation is burgeoning, but little empirical work has focused on the link between distinct types of daily goal pursuit and the depletion of self-regulatory resources. The authors conducted two studies on the link between avoidance goals and resource depletion. METHOD Study 1 (283 [228 female] Caucasians, ages 18-51) investigated the concurren...

Knowledge of ecological impacts of exotic beach almond (Terminalia catappa) in the central Pacific of Costa Rica are little known, but studies have found this species to be a potentially important food source for endangered scarlet macaws (Ara macao). In this study, reproductive phenology and seed predation by variegated squirrels (Sciurus variegatoides) and scarlet macaws were measured during ...

Building on conservation of resources theory, we cast resource depletion as a novel explanatory mechanism to explain why employees' experience of psychological contract violation results in harm to third parties outside the employee-organization exchange dyad. This resource-based perspective extends and complements the dominant social exchange perspective which views employee reactions to psych...

Sex-differential plasticity (SDP) hypothesis suggests that since hermaphrodites gain fitness through both pollen and seed production they may have evolved a higher degree of plasticity in their reproductive strategy compared to females which achieve fitness only through seed production. SDP may explain the difference in seed production observed between sexes in gynodioecious species in response...

It is proposed to replace the traditional counterpropagating laser seed in backward Raman amplifiers with a plasma wave seed. In the linear regime, namely, for a constant pump amplitude, a plasma wave seed may be found by construction that strictly produces the same output pulse as does a counterpropagating laser seed. In the nonlinear regime, or pump-depletion regime, the plasma-wave-initiated...

Body size varies considerably among species and among populations within species, exhibiting many repeatable patterns. However, which sources of selection generate geographic patterns, and which components of fitness mediate evolution of body size, are not well understood. For many animals, resource quality and intraspecific competition may mediate selection on body size producing large-scale g...

Tool use has allowed humans to become one of the most successful species. However, tool-assisted foraging has also pushed many of our prey species to extinction or endangerment, a technology-driven process thought to be uniquely human. Here, we demonstrate that tool-assisted foraging on shellfish by long-tailed macaques (Macaca fascicularis) in Khao Sam Roi Yot National Park, Thailand, reduces ...

Three studies were conducted to test the behavioral consequences of effortful self-regulation. Individuals with chronic inhibitions about eating were exposed to situations varying in level of self-regulatory demand. Subsequently, participants' ability to self-regulate was measured. Two studies manipulated self-regulatory demand by exposing participants to good-tasting snack foods, whereas a thi...
