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...

The South American soursop, guanabana or graviola fruit, was unknown to Europeans until the voyages of Christopher Columbus. The tree is now grown commercially and in home gardens throughout the tropics. The fruit is consumed as a fresh fruit and juice, and the frozen pulp is used in the...

Temperate fruit trees replanted into old orchard sites often grow poorly. A complex assemblage of soil-borne fungal plant pathogens and plant-parasitic nematodes is considered to be the primary cause of replant stress, but on coarse-textured soils restricted availability of water and key nutrients...

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 ...

The biggest challenge to humanity in the twenty-first century is global warming and climate change. Climate change reduces production and efficiency, while also increasing environmental stress on fruit and vegetable crops. Increased temperature, decreased irrigation water supply, flooding, and...

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...

Criconemoides neoinformis n. sp., a cryptic species of C. informis group, and C. persicus n. sp. were recovered from the rhizosphere of pear and grass, in Zanjan and West Azerbaijan provinces, northwestern Iran, respectively. Criconemoides neoinformis n. sp. is characterised by 522-585 μm long...

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,...
