Anat Rec (Hoboken) 2021 Jun 1. Epub 2021 Jun 1.

Tom Yawkey Wildlife Center, Georgetown, South Carolina, USA.

Despite the general perception that crocodilians exhibit indeterminate growth, recent long-term field studies and laboratory investigations have independently suggested that growth in these animals is determinate. In this study, we had the unique opportunity to examine skeletal growth in a wild adult American alligator (Alligator mississippiensis) based on change in body length measurements (snout-vent length) in the field and confirm these findings using osteohistological analyses (presence/absence of an external fundamental system [EFS]) of long bones. The alligator was captured and measured five times over 7 years and exhibited no discernable growth during that period, suggesting skeletal maturity had been attained at or prior to its first capture.

Male and female reproductive fitness costs of an immune response in natural populations.

Evolution 2021 May 15. Epub 2021 May 15.

Department of Ecology & Evolutionary Biology, University of Connecticut, Storrs, Connecticut, 06269, USA.

Parasites can mediate host fitness both directly, via effects on survival and reproduction, or indirectly by inducing host immune defense with costly side-effects. The evolution of immune defense is determined by a complex interplay of costs and benefits of parasite infection and immune response, all of which may differ for male and female hosts in sexual lineages. Here, we examine fitness costs associated with an inducible immune defense in a fish-cestode host-parasite system. Read More
