Ecophysiological constraints shape autumn migratory response to climate change in the North American field sparrow.
Our ability to accurately forecast species' geographical responses to climate change requires knowledge of the proximate and ultimate drivers of their distribution. Here, we consider the ecophysiological and demographic determinants of the distribution of a partial migrant, the North American field sparrow, Spizella pusilla. From 1940 to 1963, the field sparrow extended its winter northern rang...
متن کاملAutumn coloration as a signal of tree condition.
Hamilton and Brown suggested that bright autumn coloration in trees is an energetically expensive and therefore honest (handicap) signal of defensive commitment against insects. If this is so, one should expect that the intensity of the proposed signal should depend strongly on tree health. However, to the best of our knowledge, the link between vigour and autumn colour has never been tested. W...
متن کاملMonoamines and the control of sexual behaviour.
1 The availability of large numbers of drugs in the 1960s and 1970s resulted in an explosion of psychopharmacological studies of motivated behaviour, including sexual behaviour. The effects of some drugs, particularly those affecting serotonin and dopamine, on patterns of sexual activity in males and females of a number of non-human species were impressive and encouraged the belief, held by man...
متن کاملSexual behaviour: Courting dissatisfaction
A nuclear receptor, the product of the dissatisfaction gene, has been found to regulate Drosophila sexual behaviour, probably via its action in a small subset of neurons. The results shed new light on the genetic determination of sexual behaviour.
متن کاملHormones and sexual behaviour.
Despite new technological advances and improved assay methods, the relationship between hormones and human sexual behavior is still poorly understood. Sex drive and responsiveness, gender identification, and sexual preference are all influenced by hormones. Endocrine studies of impotent men have produced conflicting results. Exogenous androgens seem to produce some results with impotent men....
