Maternal, social and abiotic environmental effects on growth vary across life stages in a cooperative mammal.

English S, Bateman AW, Mares R, Ozgul A, Clutton-Brock TH - J Anim Ecol (2013)

Bottom Line: Most studies have measured specific factors influencing growth across development or have compared relative influences of different factors within specific life stages.Recent rainfall had a consistently marked effect on growth across life stages, yet other seasonal terms only influenced growth during stages when individuals were growing fastest.Understanding the way in which environmental sensitivity varies across life stages is likely to be an important consideration in predicting trait responses to environmental change.

Abiotic factors affecting (a, b) mass at 1 month and (c–j) growth at subsequent stages. Left panel displays effect of rain (standardized) on mass at 1 month, and right panel displays the effect of season. Shown are the predicted mean effects and 95% credible intervals for the model fit to each period. The grey points are partial residuals accounting for other terms in the model.

fig01: Abiotic factors affecting (a, b) mass at 1 month and (c–j) growth at subsequent stages. Left panel displays effect of rain (standardized) on mass at 1 month, and right panel displays the effect of season. Shown are the predicted mean effects and 95% credible intervals for the model fit to each period. The grey points are partial residuals accounting for other terms in the model.

Mentions: Rainfall in the past 2 months had a statistically significant, positive effect on mass and growth at all stages (Tables1 and 2, Fig. 1). There were marked seasonal effects on growth at the pup, juvenile and subadult stage, but not on mass at emergence or growth as adults (Tables1 and 2, Fig. 1). Growth peaked during the hot-wet months of the year (October–March) and was lowest during the cold-dry season (April–September).
