Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna. [PDF]
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient. [PDF]
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.
