Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Factors affecting establishment success of the endangered Caribbean cactus Harrisia portoricensis (Cactaceae)

open access: yesRevista de Biología Tropical, 2012
Early plant stages may be the most vulnerable within the life cycle of plants especially in arid ecosystems. Interference from exotic species may exacerbate this condition.

Height information acquisition method of seedling with machine vision

open access: yes, 2015
In plant factory, transplanting as an important step of nursery seedling process, it is necessary to achieve its automation and intelligence. To improve the survival rate of seedling transplanting, the fitness of transplanting seeding need to be ...

Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Phenology, seed dispersal and difficulties in natural recruitment of the canopy tree Pachira quinata (Malvaceae)

open access: yesRevista de Biología Tropical, 2011
Life history and recruitment information of tropical trees in natural populations is scarce even for important commercial species. This study focused on a widely exploited Neotropical canopy species, Pachiraquinata (Malvaceae), at the southernmost ...

The impact of herbivores on the natural regeneration of temperate deciduous woodland [PDF]

open access: yes, 1999
Many studies have reported deficient or intermittent patterns of natural regeneration in temperate deciduous woodland. The present study aimed to assess the relative impact of herbivore-mediated plant mortality on the natural regeneration dynamics of ...

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Comparative Analysis of CatBoost and LightGBM for Tree Seedling Survival Prediction to Support Smart Forestry

open access: yesTechno.Com
Tree seedling survival is a critical factor in forest regeneration and sustainable ecosystem management. However, predicting seedling survival remains challenging due to complex interactions between environmental conditions, soil biotic factors, and ...

Post-fire litter microsites: Safe for seeds, unsafe for seedlings

open access: yes, 1993
We explore the effect of post—fire microsites on seed and seedling distribution and hence their potential role in community restoration. A summer wildfire and control burn in a sclerophyll shrubland in mediterranean Australia produced mosaics of ...

Rising Strong: Cultivating Resilience in Edible City Entrepreneurship. Insights Into the Landscape of Urban Food Initiatives

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In response to growing global challenges, this study explores how social entrepreneurship within the Edible City movement contributes to building resilient, sustainable, and equitable urban food systems. Drawing on semistructured interviews with over 70 stakeholders across five cities—Berlin, Andernach, Oslo, Rotterdam, and Havana—we ...
