From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

PLANTS, PEOPLE, PLANET, EarlyView.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Quantifying the mutualism-antagonism continuum for seed removal by a granivorous disperser

Basic and Applied Ecology
Seeds removed by animals have one of two mutually exclusive fates – they are either predated or dispersed and still alive. The quality of seed dispersal by animals and the number of predated seeds will therefore determine net interaction outcomes for ...

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

PLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...

The Demography of Europe: Introduction

, 2013
Over the past decades Europe has witnessed fundamental changes of its population dynamics and population structure. These changes pose major challenges to population studies, as conventional theoretical assumptions regarding demographic behavior and ...

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

PLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Filling knowledge gaps: A methodological approach for the rapid investigation of species with restricted populations

Perspectives in Ecology and Conservation
Gaps in geographic, genetic, and ecological data persist for many plant species, particularly those with restricted populations that are often rare and endangered. This lack of data hampers conservation efforts, especially in regions facing rapid habitat

Long‐term demographic study reveals stabilizing mechanisms of salt marsh plants under climate change

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Despite its critical importance for biodiversity conservation, population persistence in multiple habitats under climate change has rarely been evaluated using long‐term demographic data.
