Impacts of Global Change on the Spatial Dynamics of Treeline in Venezuelan Andes

Frontiers in Ecology and Evolution, 2021
The treeline in the Andes is considered an essential ecotone between the Montane forest and Páramo. This treeline in the Venezuelan Andes corresponds with a transitional ecosystem defined as the Páramo forest.

Intersections of Conservation, Cattle, and Culture in Ecuador's Páramo Grasslands

Mountain Research and Development, 2021
Páramo is a biodiverse, high-elevation humid grassland ecosystem mainly found in the northern Andes. Since Spanish colonization, páramo lands in Ecuador have been used locally for grazing cattle that roam freely, known as ganado bravo.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

The Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

A biomimetic ducted nipple reveals gestational age‐dependent deficits in suction generation in a neonatal pig model

The Anatomical Record, EarlyView.
Abstract All infant mammals must suckle in order to effectively acquire milk from a nipple. Yet, not all infants are able to do so. Preterm infants in particular face significant feeding challenges, often failing to establish successful breastfeeding due to complex neurophysiologic challenges.

Impacts of pine plantations on carbon stocks of páramo sites in southern Ecuador

Carbon Balance and Management, 2021
Background Since the 1990’s, afforestation programs in the páramo have been implemented to offset carbon emissions through carbon sequestration, mainly using pine plantations.

Business and Biodiversity: Scaling Conservation Enterprises Within and Beyond Place for Transformative Change

Business Strategy and the Environment, EarlyView.
ABSTRACT Transformative change is required to address persistent and systemic drivers of biodiversity loss. There is an urgent need for innovative solutions that tackle root causes in place‐specific contexts. Evidence indicates that small, innovative, purpose‐driven businesses can serve as vehicles for developing place‐based solutions.
