Isoptopic evidence of the transfer of nitrogen fixed by legumes to coffee trees [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2000
The use of isotopic methods has made it possible to quantify the contribution of nitrogen fixed by a coffee plantation. Thanks to the use of the natural 15N abundance assessment technique, we were able to show that, in field condition, roughly 30/ of the

The complete chloroplast genome of Ixora chinensis and phylogenetic relationships

Mitochondrial DNA. Part B. Resources, 2021
In this study, the complete chloroplast (cp) genome of Ixora chinensis was sequenced by next-generation sequencing for the first time. The complete cp genome is 154,787 in length and contained 131 genes, consisting of 86 protein-coding genes, eight ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

To converge or diverge? Phenological shifts driven by plant genome size and functional traits under nitrogen deposition and mowing

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Linkages between genome size (GS) and phenology underscore the diversification of functional traits, which are indicative of life‐history and resource acquisition strategies.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

Insect Conservation and Diversity, EarlyView.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

A REVIEW ON THE CHEMISTRY AND PHARMACOLOGY OF Rennellia elliptica Korth

Indonesian Journal of Tropical and Infectious Disease, 2017
Rennellia elliptica, popularly dubbed as Malaysian Ginseng, is widely used in traditional medicine among the local Jakun community in Endau-Rompin State Park, Pahang, Malaysia. The decoction of the roots is traditionally taken for treatment of body aches,

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

Physiological Entomology, EarlyView.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Geographic provenance and environmental growing conditions as factors influencing phytochemical composition of Arabica green coffee beans

Plant Biology, EarlyView.
Growth environment strongly influences green coffee bean biochemistry, linking phytochemical composition to adaptation under abiotic stress. Abstract This study explores how bioactive compounds in green coffee beans (Coffea arabica L.) vary across different geographic regions, addressing the key question of how environmental factors shape coffee ...
