Herbivorous insects from diverse feeding guild cause defoliation with different intensity and dissimilar tissue effects. We studied the effects on water relations and morpho-structural and hydraulic traits of Prunus avium leaves caused by two different patterns of artificial herbivory (the window...

Within the North American boreal forest, a widespread outbreak of the epidermal leaf miner Phyllocnistis populiella Cham. has damaged quaking aspen (Populus tremuloides Michx.) for nearly 20 years. In a series of experiments, we tested the effects of feeding damage by P. populiella on leaf water...

This review of Neotropical Burseraceae emphasizes developments since the last major review of the family in 2011. The Burseraceae comprise a Laurasian group (represented by Eocene fossils in the Northern Hemisphere) that originally dispersed through Central America into Amazonia. During cooling and ...

Nearly every terrestrial ecosystem hosts invasive ant species, and many of those ant species construct underground nests near roots and/or tend phloem-feeding hemipterans on plants. We have a limited understanding of how these invasive ant behaviours change photosynthesis, carbohydrate availability ...

Pseudocryptic species, those that are difficult to diagnose using traditional taxonomic methods, are serious impediments for recognizing the introduction of non-native species. Rapid identification of species facilitates a rapid response to newly introduced species which can lessen their damaging...

These proceedings contain 137 papers focusing on agronomy and crop management, landscape plantation ecosystem, post-harvest and processing technology, and biodiversity and climate change. Topics include pest control, metagenomics, seed production, plant pathogens, plant breeding and genetics,...

Two new species of wood wasps (Anaxyelidae), Orthosyntexis elegans gen. et sp. nov. and Orthosyntexis thanti sp. nov., are described from mid-Cretaceous Kachin amber. Orthosyntexis gen. nov. exhibits characters and character combinations unique to the family, such as the combination of two...

Hemlock woolly adelgid (HWA) is an exotic insect pest causing severe decimation of native hemlock trees. Extensive research has been conducted on the ecological impacts of HWA, but the exact physiological mechanisms that cause mortality are not known. Water relations, anatomy and gas exchange...

Gall wasps (Hymenoptera: Cynipidae) specializing on live oaks in the genus Quercus (subsection Virentes) are a relatively diverse and well-studied community with 14 species described to date, albeit with incomplete information on their biology, life history and genetic structure. Incorporating an...
