Physiology and Survival of Intertidal Calcifiers in Two Contrasting Upwelling Systems. [PDF]

open access: yesEcol Evol
This study evaluates the physiological responses and survival of two intertidal mollusk species, Chiton granosus and Scurria zebrina, across contrasting upwelling environments. We found that metabolic rates and survival differ between populations exposed to seasonal versus semi‐permanent upwelling.

Providing evidence for the conservation of a rare forest butterfly: Results from a three-year capture-mark-recapture study

open access: yesBasic and Applied Ecology, 2023
Species living in spatially structured populations require a network of interconnected habitat patches. Due to changes in forest management, this network of habitat patches has been lost for insect species inhabiting open spots within forests. We studied
