Effects of social organization, age and aggressive behaviour on allosuckling in wild fallow deer

Article Abstract:

Several hypotheses propose to explain how communal nursing, or allosuckling, under natural conditions could be adaptive for adult females. It could be based on reciprocity, may increase group size or may be of selective advantage. The occurrence, frequency and distribution of allosuckling in wild fallow deer, Dama dama, were investigated. It was concluded that allosuckling may be the result of kin selection and/or reciprocal altruism.

Anatomical constraints generate honesty: acoustic cues to age and weight in the roars of red deer stags

Article Abstract:

A detailed acoustic analysis was conducted to examine the variables, which are provided for the honest information on age, body weight and reproductive success. This study, concentrated on the extensive database of roars from red deer stags, reveals that fundamental frequency was higher in young stags than in adults, and will not decrease with body weight within adults.
