Asynchronous breeding in red brocket deer (Mazama americana): seasonal changes in male reproductive characteristics, seminal parameters, androgen levels, and antler cycle
(2020-06-01)
The red brocket deer is the largest species in the genus Mazama and one of the most abundant and widely distributed cervid in the Neotropics. Yet it has been classified as data deficient by the IUCN, and the limited knowledge ...
Annual variations in fecal androgen metabolites and antler cycle of captive red brocket bucks (Mazama americana) in southeast Brazil
(Springer, 2009-10-01)
Annual variations in fecal androgen metabolites (FAM) and antler cycle were analyzed in six red brocket bucks exposed to a natural photoperiod in southeast Brazil. Fecal samples and antlers status data were collected weekly ...

Reproduction of white-tailed deer in a seasonally dry tropical forest of Costa Rica: A test of aseasonality
(Oxford University Press, 2020-02-21)
The reproductive season of white-tailed deer (Odocoileus virginianus) has been hypothesized to be aseasonal
south of about 14°–18°N latitude, where annual variation in day length is low. We tested this idea by using
camera-trap ...

Reproduction in the Eared Dove: An exception to the classic model of seasonal reproduction in birds?
(Elsevier Gmbh, 2020-06)
In avian species living at high altitudes and latitudes, reproductive events are largely controlled by photoperiod, with changes being perceived mainly through encephalic photoreceptors located in the hypothalamus. It is ...
Reproductive ecology of dipsadine snakes, with emphasis on South American species
(HERPETOLOGISTS LEAGUE, 2008)
A relatively large amount of variation occurs in the reproductive ecology of tropical snakes, and this variation is generally regarded as being a consequence of seasonality in climate and prey availability. In some groups, ...
