Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient. [PDF]

New Phytol
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.

Microbial drivers of root plasticity. [PDF]

New Phytol
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Estimation of additive genetic variance when there are gene–environment correlations: Pitfalls, solutions and unexplored questions

Methods in Ecology and Evolution, Volume 14, Issue 5, Page 1245-1258, May 2023., 2023
Abstract Estimating the genetic variation underpinning a trait is crucial to understanding and predicting its evolution. A key statistical tool to estimate this variation is the animal model. Typically, the environment is modelled as an external variable independent of the organism, affecting the focal phenotypic trait via phenotypic plasticity.

Parasitic flowering plant collections embody the extended specimen

Methods in Ecology and Evolution, Volume 14, Issue 2, Page 319-331, February 2023., 2023
Abstract The widespread digitization of natural history collections, combined with novel tools and approaches is revolutionizing biodiversity science. The ‘extended specimen’ concept advocates a more holistic approach in which a specimen is framed as a diverse stream of interconnected data.

Plasticity and evolution shape the scaling of metabolism and excretion along a geothermal temperature gradient

Functional Ecology, Volume 36, Issue 5, Page 1303-1314, May 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physiological rates are heavily dependent on temperature and body size. Most current predictions of organisms’ response to environmental warming are based on the assumption that key physiological rates such as metabolism and excretion scale independently with body size ...
