Analysis of western New York forest soundscapes across spatial and temporal gradients

An analysis of western New York soundscapes revealed no variation in the overall amount of biodiversity from the center to the edge of forest plots. The biodiversity did not change in these soundscapes from the late spring to the late summer, even though the dominating vocalizing taxa in these soundscapes did differ between the time periods.

Pine health and tree death: It’s complicated

Southern pine production drives the forest industry in the southeastern US, and recent mortality of pines in this region has caused concern with growers. We evaluated factors impacting pine health. There is no single cause of pine mortality, although many factors contribute. Overall, mortality is site-specific, not regional.

Are neotropical predictors of forest epiphyte–host relationships consistent in Indonesia?

Neotropical studies show links between host tree morphology & epiphyte richness. We study these in Buton, Indonesia, recording: site, above-ground biomass, altitude, bark texture, emergence & crown area of 44 trees. GLMs show % deviance explained for richness are: agb (20.9%), crown area (19.6%) & site (15.5%); similar results to the Neotropics.

Population structure of the invasive tree Ailanthus altissima

We investigated the role of land-use on the geneflow of the invasive tree Ailanthus altissima. No evidence of clonal reproduction was found at the population level. Geneflow was independent of geographic distance. Population structuring at managed sites suggests that land management practices were effective at inhibiting invasive spread.

Entomopathogenic fungi antagonizing a phytopathogenic fungus

Entomopathogenic fungi (EPF), mainly used for arthropod control appear to antagonize phytopathogens and improve crop health. Three EPF, and botanical and bacteria-based fungicides limited Fusarium oxysporum f.sp. vasinfectum in cotton. The multipurpose use of EPF for both pest and disease management is beneficial to sustainable agriculture.

Plants vs Botrytis (a fungi pathogen)

Plant/pathogen interactions determine plants yield in wild and agronomic environments. We measured lesion development of 100 Botrytis isolates across lineages of crop species. We describe large diversity of response from both plants and pathogen and discuss how it help could address resistance to this pathogen.
