Although the evolutionary importance of spontaneous mutation is evident, its contribution to the evolution of ecological specificity remains unclear, because the environmental sensitivity of effects of new mutations has received little empirical attention. To address this issue, we report a greenhouse in which we grew plants from 20 mutation-accumulation (MA) lines, advanced by selfing and sing...

Records from 75,941 Nelore cattle were used to determine the importance of genotype by environment interaction (GEI) in five Brazilian states. (Co)variance components were estimated by single-trait analysis (with yearling weight, W450, considered to be the same trait in all states) and multiple-trait analysis (with the record from each state considered to be a different trait). The direct herit...

Potential excess use of health care services caused by insurance has been a major concern for almost every industrialized county. Moral hazard problems and fee-for-service payment methods are considered to be important factors for higher medical care utilization among those insured. Health care availability is another feature reportedly associated with health care use. Using the data from a Nat...

Competition between individuals belonging to the same species is a universal feature of natural populations and is the process underpinning organismal adaptation. Despite its importance, still comparatively little is known about the genetic variation responsible for competitive traits. Here, we measured the phenotypic variation and quantitative genetics parameters for two fitness-related traits...

Automatic gender classification of an individual can be very useful in video-based surveillance systems and human-computer interaction systems. Currently, gait from a single viewpoint has been used to recognize the gender of a person. Considering the multiple cameras used in real environments, we investigate gender classification from human gait by using multi-view fusion, a relatively understu...

In computer vision applications, gait-based gender classification is a challenging task as person may walk at various angles with respect to the camera viewpoint. some of viewing angles, person’s limb movement can be occluded from camera, preventing perception features. To solve this problem, study proposes robust and lightweight system for classification. It uses gait energy image (GEI) repres...

The effectiveness of poisoning feral goats (Capra hircus L.) with Compound 1080 on natural vegetation baits was tested and compared with a hunting campaign. Both control methods probably killed over 90% of the goats in treatment blocks of 1200 ha, but the poisoning method required less skill than hunting. Melicytus ramiflorus Forst., Schefflera digitata J.R. et G. Forst., Coprosma lucida J.R. e...
