Theories of care help explain a peri‐urban tree diversity paradox

People and Nature, EarlyView.
Abstract Since diversity is often a management objective for peri‐urban tree communities on public land, one might expect to find greater diversity there than on private land, where such objectives are less common. However, this expectation rests on an assumption that people control diversity towards objectives, overlooking the role of relationships ...

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.

Influence of gap size and development stages on the silvicultural characteristics of oriental beech (Fagus orientalis Lipsky) regeneration

Caspian Journal of Environmental Sciences, 2011
We studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, Langa forest, watershed 36: Kazemrood) of the Caspian beech forest in N Iran.

The influence of stand spatial structure on understory sapling species diversity in natural forests of Qujiang District

Ecological Indicators
Understory sapling regeneration is crucial for maintaining the stability and functioning of forest ecosystems. To investigate the mechanisms through which stand spatial structure influences understory sapling species diversity and to identify key driving

Design of a Sapling Branch Grafting Robot [PDF]

Journal of Robotics, 2014
The automatic sapling grafting methods and grafting robot technologies are not comprehensively studied despite the fact that they are urgently required in practice. For this reason, a sapling grafting robot is developed to implement automatic grafting for saplings.

Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

PLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

Close‐to‐nature management regulates ecosystem carbon storage through its effects on vegetation community structure in Pinus massoniana plantations

PLANTS, PEOPLE, PLANET, EarlyView.
Forest plantations play an increasingly important role in climate change mitigation through carbon sequestration, yet management strategies that enhance long‐term ecosystem carbon storage remain insufficiently understood. We investigated the effects of more than a decade of close‐to‐nature management on community structure and ecosystem carbon storage ...
