Agonism does not covary with territoriality in a gregarious reptile

چکیده
Abstract Natural selection for territoriality is theorised to occur under conditions favouring intra-sexual phenotypic variation in physiology, morphology, and behaviour. In this context, certain suites of behavioural traits associated with are expected consistently covary among individuals (sometimes referred as ‘behavioural syndromes’) within sexes. Agonism (conflict-associated behaviours that may or not be physical aggression) movement—for example, ranging, relocation across seasons—are two components context. Territorial males employ agonistic actively establish defend areas resources show more stability their location the landscape. However, interaction between agonism movement especially wild reptiles has rarely been tested. We investigated whether correlate at individual level both one year multiple years, a population Australian eastern water dragons, Intellagama lesueurii . Although types exhibited among-individual repeatability over multi-year scales, we found no evidence an agonistic-movement syndrome. These findings indicate likely independent traits, thus, drive shared selective pressures both. It possible other social strategies place maintain structure population. Significance statement Males many animals territories. Territory defence conflict expressions dominance, signal territory boundaries encroaching individuals, aggressive approaches active defence. such correlated distances ranged dispersed indicator territoriality. Through thousands observations , although showed repeatable patterns behaviours, these were correlated. appears establishment therefore rely on signals species direct contrast taxa, indicating systems structures.

Nonuniform activation of the agonist muscle does not covary with index finger acceleration in old adults.
This study examined the patterns of activation in the superficial and deep parts of the first dorsal interosseus muscle and in the antagonist muscle, second palmar interosseus, during postural tasks (position holding) and slow movements (position tracking) of the index finger performed by young and old adults. The position-tracking task involved the index finger lifting light loads (2.5, 10, an...
متن کاملCoactivation of the antagonist muscle does not covary with steadiness in old adults.
The purpose of the study was to determine the association between steadiness and activation of the agonist and antagonist muscles during isometric and anisometric contractions. Young (n = 14) and old (n = 15) adults used the first dorsal interosseus muscle to perform constant-force and constant-load tasks (2.5, 5, 20, 50, and 75% maximum) with the left index finger. Steadiness was quantified as...

BACKGROUND Data conflict with regard to whether peroxisome proliferator-activated receptor-α agonism suppresses inflammation in humans. We hypothesized that in healthy adults peroxisome proliferator-activated receptor-α agonism with fenofibrate would blunt the induced immune responses to endotoxin (lipopolysaccharide [LPS]), an in vivo model for the study of cardiometabolic inflammation. METH...
متن کاملReality Does Not Recognize Borders
Reality does not recognize borders. Why we should use the very general term of “reality” and not science, because the borders that we draw are pure delusions, and on the opposite side there is the reality. The laws of the universe, either the physical nature of the world which the scientist studies or metaphysics which is the territory of philosophers, it isthe same reality that rules. Today ma...
