Historical climate change and vicariance events contributed to the intercontinental disjunct distribution pattern of ash species (Fraxinus, Oleaceae)

open access: yesCommunications Biology
The Northern Hemisphere temperate forests exhibit a disjunct distributional pattern in Europe, North America, and East Asia. Here, to reveal the promoter of intercontinental disjunct distribution, Fraxinus was used as a model organism to integrate ...

Edaphic effects on forest structure and tree species composition in three seasonally dry tropical forest types in Cambodia

open access: yesNordic Journal of Botany, EarlyView.
Soil conditions are critical factors shaping forest structure and tree species composition in seasonally dry tropical forests (SDTFs); however, few studies have evaluated edaphic effects in Cambodia's unique lowland forest landscape, where different forest types coexist under similar climatic conditions.

Phylogenomic approaches untangle early divergences and complex diversifications of the olive plant family

open access: yesBMC Biology, 2022
Background Deep-branching phylogenetic relationships are often difficult to resolve because phylogenetic signals are obscured by the long history and complexity of evolutionary processes, such as ancient introgression/hybridization, polyploidization, and

Controlling for genetic identity of varieties, pollen contamination and stigma receptivity is essential to characterize the self-incompatibility system of Olea europaea L. [PDF]

open access: yes, 2017
open7siBervillé et al. express concern about the existence of the diallelic self-incompatibility (DSI) system in Olea europaea, mainly because our model does not account for results from previous studies from their group that claimed to have documented ...

Phylogenetic diversity and interspecies competition shaped species diversity in adaptive radiated Ligustrum (Oleaceae)

open access: yesJournal of Systematics and Evolution
Speciation events often occur with adaptive radiation. The factors that promote these adaptive radiating species diversity patterns have intrigued biologists for more than a century.

Leaf longevity and structure, fruit mass and phenology in 52 cultivated varieties and wild accessions of olive

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although phenology has long been recognized as a critical feature for the adaptation of organisms to their local environment, until recently, phenological events have seldom been considered in the broader context of trait‐based ecology.

Richness of social wasps (Hymenoptera: Vespidae: Polistinae) in an olive crop (Olea europaea L.), area associated with a mixed fragment of Atlantic Forest in southern Minas Gerais state, Brazil

open access: yesRevista Chilena de Entomología
The presence of Atlantic Forest fragments adjacent to agricultural areas enhances agricultural production by supporting populations of natural enemies, such as social wasps, which play a role in biological control.
