What influences child feeding in the Northern Triangle? A mixed-methods systematic review. [PDF]

Matern Child Nutr, 2020
Abstract Optimising child feeding behaviours could improve child health in Guatemala, Honduras and El Salvador, where undernutrition rates remain high. However, the design of interventions to improve child feeding behaviours is limited by piecemeal, theoretically underdeveloped evidence on factors that may influence these behaviours.

Phylogenomics of arboreal alligator lizards shed light on the geographical diversification of cloud forest‐adapted biotas

Journal of Biogeography, Volume 49, Issue 10, Page 1862-1876, October 2022., 2022
Abstract Aim The proximate ecological and evolutionary processes underlying the high biodiversity of neotropical montane cloud forests are still very poorly understood. Climatic oscillations may have contributed to vicariance and cladogenesis, but also promoted secondary contact and erosion of genetic divergence.
