Local perceptions as a guide for the sustainable management of natural resources: empirical evidence from a small-scale society in Bolivian Amazonia [PDF]

Ecology and Society, 2016
Research on natural resource management suggests that local perceptions form the basis upon which many small-scale societies monitor availability and change in the stock of common-pool natural resources. In contrast, this literature debates whether local

Diversity and conservation status of palms (Arecaceae) in two hotspots of biodiversity in Colombia and Ecuador

Plants, People, Planet
Societal Impact Statement Palms provide vital plant resources and ecosystem services to people across the tropics. To improve conservation guidance, a “health check” of palms in two highly threatened biodiversity hotspots in Colombia and Ecuador was ...

Hybridization in palms (Arecaceae). [PDF]

Ecol Evol
Across the plant Tree of Life, hybridization has contributed to the formation of species complexes and biased our understanding of taxonomic diversity and phylogenetic relationship, palms included. To increase understanding, we explore hybridization in palms and test for ecological correlates of hybridization. We reveal that hybridization is not evenly

Not All Stress Is the Same: Variable Associations Between Psychosocial Stressors and Urinary Cortisol Rhythms in a Small-Scale Subsistence Society. [PDF]

Am J Hum Biol
ABSTRACT Objectives Dysregulations of the hypothalamic–pituitary–adrenal (HPA) axis have been linked to adverse health outcomes such as obesity, cardiovascular disease, and diabetes. While research on the HPA axis is growing, few studies have examined whether different types of stressors affect HPA functioning differently, and none have done so in ...

Climate Change Vulnerability and Conservation Priorities for Atlantic Forest Palms. [PDF]

Ecol Evol
Climate change may reduce palm richness in the northern and central Atlantic Forest. Some palms may lose their entire range areas, while others may expand in the future. Range‐restricted palms tend to be more vulnerable to climate change. ABSTRACT Climate change is expected to significantly impact biodiversity, causing shifts in palm species ...

The ecology of palm genomes: repeat-associated genome size expansion is constrained by aridity. [PDF]

New Phytol, 2022
Summary Genome size varies 2400‐fold across plants, influencing their evolution through changes in cell size and cell division rates which impact plants' environmental stress tolerance. Repetitive element expansion explains much genome size diversity, and the processes structuring repeat ‘communities’ are analogous to those structuring ecological ...

Root anatomy of Venezuelan species of Geonoma (Arecaceae: Arecoideae: Geonomateae)

Rodriguésia, 2021
In this research we studied root anatomy of eight species and two morphotypes from the genus Geonoma in Venezuela, in order to explore their structural and taxonomic implications. Fresh material sampled wild population was fixed in FAA and hand-sectioned

Floral attraction and flower visitors of a subcanopy, tropical rainforest tree, Fontainea picrosperma. [PDF]

Ecol Evol, 2021
Pollinators beneath the rainforest canopy occupy a unique microclimate that is markedly different from the canopy environment that receives more light energy. We studied the floral attractants and floral visitors of a dioecious, subcanopy rainforest tree, Fontainea picrosperma (Euphorbiaceae), in northern Australia.

Genotyping-by-sequencing informs conservation of Andean palms sources of non-timber forest products. [PDF]

Evol Appl
Abstract Conservation and sustainable management of lineages providing non‐timber forest products are imperative under the current global biodiversity loss. Most non‐timber forest species, however, lack genomic studies that characterize their intraspecific variation and evolutionary history, which inform species' conservation practices.
