Foliar secretory structures in Ekebergia capensis (Meliaceae)

Heliyon, 2018
Ekebergia capensis is a medium-sized to large evergreen to deciduous tree ranging from southern Africa to Ethiopia. Two morphologically-distinct variants of E. capensis, southern and northern, may be recognized in southern Africa.

Nectaries and nectar

, 2007
Nectar is the most important reward offered by plants to pollinating animals. This book is a modern and interdisciplinary text on nectar and nectaries, prompted by the expansion of knowledge, especially in the more ecological and now molecular fields ...

Does Reproductive Success in Natural and Anthropogenic Populations of Generalist Epipactis helleborine Depend on Flower Morphology and Nectar Composition?

International Journal of Molecular Sciences, 2023
The purpose of our study was to determine the role of flower structure and nectar composition in shaping the reproductive success (RS) of the generalist orchid Epipactis helleborine in natural and anthropogenic populations.

Smart detection of juice adulteration: An approach based on ion mobility spectrometry and machine learning

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fruit juice quality is regulated by European Union legislation; however, adulteration by adding cheaper alternatives, such as white grape juice, remains a prevalent issue. This practice constitutes economic fraud and poses health risks to consumers, including potential allergic reactions to the adulterant.

Diurnal nectar secretion dynamics in Roscoea cautleoides (Zingiberaceae) reveal the role of non-sugar chemicals in plant–pollinator interaction

Current Plant Biology
Floral nectar is essential for plant-pollinator interactions, directly influencing plant reproduction. Although the composition of nectar has been widely studied, the daily dynamics of non-sugar components in the nectar remain unknown.

Biologia da polinização em Lecythidaceae

Acta Botânica Brasílica, 1987
A família Lecythidaceae apresenta grande diversidade em matas higrófilas localizadas abaixo de 1000 m de altitude. Poucas espécies ocorrem em cerrados, várzeas, e em matas acima de 1000 m.

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
