主 题:antler size body mass early-life investment Mediterranean environments secondary sexual traits and senescence trade-offs
摘 要:Recent research has challenged the idea that cervid antlers are such costly traits,supporting the assertion early-life antler investment is an honest signal of adult phenotypic ***,inferences were made based on antler measurements while growing(velvet)and thus,studies on fully-formed clean antlers are needed to avoid possible bias caused by the inter-individual variation in antler growth *** studied a semi-captive population of European roe deer inhabiting a sub-Mediterranean area(Valsemana research station)and living under optimal conditions(ad libitum food supply and veterinary care).Based on repeated measurements taken from 146 individuals,we assessed whether allocation to secondary sexual traits during early life affected body mass or antler development during ***,we evaluated which body measurements better predicted future male ***,using 488 individuals,we described age-class-specific variation in male body measurements and assessed the decline in antler size between adult and senescent stages(*** of senescence).Results agree with the assertion that there is no negative effect of a high investment in antler during early life on adult antler size or body mass,but we suggest the use of clean antlers as a more robust and reliable *** variables that better predicted body mass during adulthood were yearling body mass and body size at 6 *** score between 10 and 18 months resulted in the best indicator of adult antler ***,we support the idea that the magnitude of senescence in antler size is smaller in environments with higher resource availability during winter.
