nonkin

They were then given a choice to share the food with kin or nonkin.

Yet eight of the 11 females did not discriminate between kin and nonkin.

Nonkin, when there was her own lifemate to aid her?

However, in populations with low genetic variation, the recognition of kin and nonkin individuals could be compromised.

Nonkin dyads were characterized almost entirely by agonistic behaviour.

Although there was greater proximity among kin than among nonkin, each adult maintained a separate core area.

Thus tadpoles associate with siblings because they are attracted to kin rather than repulsed by nonkin.

"Thank you," she said, choosing the High Tongue mode of Nonkin, which was cool.

Since kinship is the major way in which these societies are organized, nonkin (strangers) are viewed negatively.

March 10 (25) The complexity of social behaviour: competition among kin -- cooperation among nonkin?

However, the scientists emphasized that the theory predicts animals will accept only very young nonkin, when their chance of successful phenotypic cloning is highest.

All that matters, they say, is that the hamsters, for whatever reason, distinguish between kin and nonkin solely by their own smells.

The benefit to the mother is decreased due to less food availability for herself and the cost remains great for nonkin due to not receiving food.

"I beg your pardon," she whispered, answering the warmth of Comrade mode with the coolth of Nonkin.

Thereafter, juveniles become increasingly independent from the family unit, establishing their own spatially distinct core areas and exhibiting site-dependent dominance toward nonkin.

Tadpoles associated preferentially with siblings over no larvae, but showed no preference for either nonkin or no larvae.

First, if schreckstoff evolved by kin selection, more epidermal alarm substance cells would be expected to be produced in the presence of kin than nonkin.

In the first set of observations, we provided tadpoles the opportunity to associate with (i) siblings or no larvae and (ii) nonkin or no larvae.

In balance, Daav should make answer in Addressing One Not of His Clan, which came uncomfortably close to Nonkin.

Diversity of ties was measured by the relative proportion of kin in the network and the number of different nonkin and kin types in the network.

Behavioural interactions among mother–offspring and adult female – nonkin dyads from the wild were quantified in a neutral arena during (i) the autumn when offspring were immature subadults, and (ii) the following spring, when all dyad members were reproductively active.

Languages generally have developed systems of address - what you call a person when you talk to them face to face - which reflect the salient social distinctions of the culture (kin versus nonkin, intimate versus nonintimate, higher/lower status, to mention some very common ones).

In this study, we tested the influence of density and relatedness on larval development in a genetically impoverished population of the pool frog (Rana lessonae Camerano, 1882), exposing individuals from four families to two densities and to competition by full-sibling and nonkin larvae.

Human beings are elaborately, ineluctably social creatures, scientists say, and are more willing than any other species to work for the common good - to cooperate with nonkin and to help out strangers, sometimes at great cost to oneself, as the death of hundreds of rescue workers at the World Trade Center only too sadly showed.
