Climate-induced shifts in ontogenetic niches threaten ecosystem coupling.

Ontogenetic niche shifts are widespread and play a crucial role in ecosystems coupling. However, their interactions with climate change and the resulting impact on cross-ecosystem energy pathways should be better investigated. I address ecological and evolutionary responses of ontogenetic niche shifts to climate change.

Impacts of an organophosphate pesticide and water restriction on physiology and immunity in the passerine Zonotrichia capensis.

Climate change, specifically rising temperatures and increased frequency of droughts will increase the level of exposure of organisms to chemical pollution. Notably, the impact of increased frequency and duration of drought events and subsequent dehydration on pesticide toxicity remains largely unknown. We evaluated the combined effects of exposure to the pesticide Chlorpyrifos (CPF) and water restriction (WR) on the enzymatic activities of three plasma esterases (acetylcholinesterase, butyrylcholinesterase and carboxylesterase), basal metabolic rate (BMR), leukocyte profile (proportion of heterophils to lymphocytes; H:L ratio), and bactericidal capacity of plasma in the rufous-collared sparrow (Zonotrichia capensis), a common passerine bird in Chile.

Development and Implementation of a Geriatric Oncology Interdisciplinary Case-Based Educational Intervention for Cancer Care Providers.

Purpose: To develop and implement a continuing professional development (CPD) activity focused on geriatric assessment (GA) in oncology for oncologists and geriatricians. We evaluated the impact of this activity on knowledge, skills, and performance regarding GA in oncology, as well as its feasibility and acceptability.

Methods: We included teams composed of an oncologist and a geriatrician working in Mexico.
