Holocene Fires and Ecological Novelty in the High Colombian Cordillera Oriental

Frontiers in Ecology and Evolution, 2022
Rapid climate changes and the increasing presence of humans define the Holocene Epoch (11.6 calibrated kiloyears before present – hereafter kyr BP), when biological systems have faced the most recent and abrupt environmental changes. Understanding how biodiversity responds to extrinsic factors requires determining the effects of varying climatic ...

Species diversity and host plant associations of ambrosia beetles in Southeast Asian forests of Laos and Vietnam revealed by DNA barcoding

Insect Conservation and Diversity, EarlyView.
Integrative DNA barcoding of ambrosia beetles and host plants revealed 27 beetle species across 16 genera and extensive, previously undocumented host plant diversity in Laos and Vietnam. Host specificity varied widely among ambrosia beetles, with Xylosandrus crassiusculus emerging as a dominant generalist associated with 19 host species from 12 plant ...
