Comparative anatomy and genetic bases of fruit development in selected Rubiaceae (Gentianales). [PDF]
Am J Bot, 2021 Abstract Premise The Rubiaceae are ideal for studying the diversity of fruits that develop from flowers with inferior ovary. We aimed to identify morpho‐anatomical changes during fruit development that distinguish those derived from the carpel versus the extra‐carpellary tissues.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]
Biol Rev Camb Philos SocABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Changing Rainfall Drives Locally Asynchronous Reproduction of Tropical Birds via Modular Trophic Pathways. [PDF]
Glob Chang BiolIn low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics. [PDF]
Glob Chang Biol, 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

Globally Distributed Arbuscular Mycorrhizal Fungi Associated With Invasive Cinchona pubescens on Santa Cruz Island, Galápagos. [PDF]
Ecol EvolArbuscular mycorrhizal fungi (AMF) are crucial for plant survival and may influence the success of invasive species. This study investigated the AMF communities associated with the invasive Cinchona pubescens on Santa Cruz Island, Galápagos, and in its endangered native range in Ecuador.

Biotropica, Volume 55, Issue 6, Page 1215-1232, November 2023., 2023 In Puerto Rico, a tropical archipelago in a region characterized by complex socio‐economic and environmental change, ecological knowledge of the local insect fauna is scarce. Greater emphasis on ecological monitoring of model insect groups like Lepidoptera could provide insight into the effects of global change on tropical biodiversity and contribute ...

Pest categorisation of Pulvinaria psidii
EFSA Journal, Volume 20, Issue 8, August 2022., 2022 Abstract The EFSA Panel on Plant Health performed a pest categorisation of Pulvinaria psidii (Hemiptera: Coccidae), the green shield scale, for the EU. P. psidii was originally described from Hawaii on Psidium sp. and it is now established in many countries in tropical and subtropical regions of the world. Within the EU, the pest has been reported from

American Journal of Botany, Volume 108, Issue 7, Page 1143-1165, July 2021., 2021 Premise Comprising five families that vastly differ in species richness—ranging from Gelsemiaceae with 13 species to the Rubiaceae with 13,775 species—members of the Gentianales are often among the most species‐rich and abundant plants in tropical forests. Despite considerable phylogenetic work within particular families and genera, several alternative

Wildlife Biology, Volume 2019, Issue 1, Page 1-6, December 2019., 2019 Many deforested areas worldwide have been planted with Alnus spp. to protect watersheds and soils. However, the effects of these plantations on biodiversity are little known yet. Contrasting forest types may impose strong environmental filters to some behavioural traits, leading to dissimilar communities.

Peptide Science, Volume 100, Issue 5, Page 438-452, September 2013., 2013 ABSTRACT Cyclotides are a unique class of ribosomally synthesized cysteine‐rich miniproteins characterized by a head‐to‐tail cyclized backbone and three conserved disulfide‐bonds in a knotted arrangement. Originally they were discovered in the coffee‐family plant Oldenlandia affinis (Rubiaceae) and have since been identified in several species of the ...
