Handedness is a biomarker of variation in anal sex role behavior and Recalled Childhood Gender Nonconformity among gay men Developmental theories of the biological basis of sexual orientation suggest that sexually differentiated psychological and behavioural traits should be linked with sexual orientation. ...
Differences in male and female traits (sexual dimorphism [SD]) are widespread in animals. Dimorphism in morphological characters evolves under the effect of environmental and genetic factors and is s...
Peter A. Zimmerman, in Infection, Genetics and Evolution, 2014 3.3 Ancestral state of host preference Along with estimating a MRCA between species, we can also examine other traits with reference to the phylogeny, such as shared host preference. The known host specificity of extant filarial ...
or to convince host parents of nestling value to avoid desertion, as host parents may desert progeny that take an atypical long time to fledge (Grim et al. 2003;Grim 2007). Other traits have also been revealed to act as solicitation enhancers, such as the colorful gapes of the Common Cuck...
The comparison of sensorimotor systems in different species and with different functions can help to recognize common traits as well as evolutionary innovations. Such comparisons reveal that, by instance, the intratelencephalic vocalization circuits of song birds and budgerigar have some traits ir. ...
orientalis), have found no support for the EMH, despite the inclusion of egg-spot traits. Several studies have suggested that egg color is a more important recognition cue than spot patterns (Moskát et al. 2008; Spottiswoode and Stevens 2010). However, relative to egg color, the spottiness...
the same driver can have opposing effects on population abundance at different sites45. A lack of biome-specific directional trends in population change, despite a spatial clustering of human pressure around the world12, can also arise owing to differences in species traits and vulnerability to envi...
It is one of those rare cases when a hybrid exhibits completely unique traits. You’ll also find such distinctive hybrid iridescence in our next crossbred bird. Black Grouse x Capercaillie In the wilderness of the Old World, the Black Grouse and the Eurasian Capercaillie can create a distinct ...
Fast life history traits promote invasion success in amphibians and reptiles Competing theoretical models make different predictions on which life history strategies facilitate growth of small populations. While 'fast' strategies al... WL Allen,SE Street,I Capellini,... - 《Ecology Letters》 被引量...
