The Linscott Lab at New Mexico State University is seeking motivated graduate students (MS or PhD) for Fall 2026. Our research explores the rules of life that govern the expression and diversity of biological forms in nature, how these rules shape biodiversity across micro- and macroevolutionary scales, and exposing their relevance for the conservation of extant species. Our work centers on ecophysiological constraints (EPCs) - physiological limitations modulated by the environmental availability of key metabolic resources. These ‘rules of life’ influence the energetic costs of trait synthesis and function based on the availability of a limiting environmental resource. We use EPCs as ways of understanding how the environment has shaped morphology, spatial patterns of biodiversity, and adaptive divergence through time and space. As a way to understand ecophysiological evolution more generally across both micro- and macroevolutionary timescales, we primarily use non-marine molluscs as an empirical system. However, we also welcome students interested in other ecophysiologically constrained groups (e.g., diatoms, plants, crustaceans). Our goal is to leverage variation across different clades, environments, morphologies, and body plans to advance a general understanding of ecophysiology and systematics. Many of our projects address the habitat requirements, systematics, and conservation of species of concern, often in direct collaboration with wildlife managers and conservation agencies. We employ diverse approaches including isotopic analyses, population genomics, and phylogenetic comparative methods to address both applied and basic science questions.
