Two opposite phenomena have been found in territorial animals, the "dear enemy'' and the ''nasty neighbour'', which refer to individuals that show less aggression toward neighbours than toward strangers and vice versa. However, the need to maintain territory should differ for males and females because sexual reproduction is the result of the differ...

Studies of abundance and distribution of organisms are fundamental to ecology. The identity of host species is known to be one of the major factors influencing ectoparasitic flea abundance, but explanations are still needed regarding how host taxa influence abundance parameters of different flea species. This study was carried out at La Malinche Na...

We studied serum testosterone levels in the endemic Mexican cottontail, Sylvilagus cunicularius, which has been reported to show seasonal breeding. Animals were trapped in the wild and in a field enclosure in the National Park La Malinche in central Mexico over a period of five years. Serum testosterone (T) levels were quantified by ELISA from bloo...

Selective transection of peripheral nerves that innervate the pelvic region results in the alteration of some aspects of copulatory behavior, including seminal plug weight. Both branches of the genitofemoral nerve primarily innervate the cremaster muscle although the genital branch has a wide distribution in the cremasteric sac. Thermoregulation of...
