Fiction and Fantasy in Urban Geographies: Reimagining Toronto’s Ravine Systems

Toronto’s ravine system is the foremost defining geography in the city. The forested ravines cover nearly 20% of the city, according to the Guardian. In the words of Robert Fulford, author of Toronto, Accidental City, “they are the heart of the city’s emotional geography, and understanding Toronto requires an understanding of the ravines.” The environmental … Read more

Aquatic Invasive Species Management in NH Waterbodies

Transgenerational plasticity in the annual plant Polygonum persicaria: effects of the grandparent environment on plant development

Abstract: The Sultan lab studies phenotypic plasticity and its transgenerational effects in the generalist, annual plant Polygonum persicaria. Phenotypic plasticity describes the ability of a single genotype to produce multiple phenotypes (physical traits) in different environments. The plasticity we study allows plants to integrate information from their current and previous (parental and grandparental) environments in … Read more

Phytohormone Pathway Crosstalk and the Relationship Between Defoliating Herbivores and Phloem-Feeding Insects on White Oak Trees

Abstract: Ecosystems are full of complex interactions between species ranging from direct, such as an insect consuming a leaf, to indirect, like the indirect interactions between two insects that share the same food source. One of these many interactions is the relationship of defoliating herbivores and phloem-feeding insects. Phloem-feeding insects trigger a defensive response in … Read more

Reconstructing environments of medicinal plants of the ancient Mediterranean

Abstract: In his De materia medica, Dioscorides catalogues thousands of medicinal plants from across the Mediterranean and identifies the regional sources of the most potent varieties.  As of yet, no effort has been made to analyze the regional, environmental conditions of the locations noted by Dioscorides and other contemporary authors like Pliny the Elder, in … Read more

Vegetation recovery, plant hydrology, and functional differences post-fire evapotranspiration in a southwestern pine-oak forest, Arizona, USA

Abstract: Post-fire stand, water balance, and hydrology are critical factors influencing vegetation recovery after a wildfire. Fire severity, and the amount of fire-induced tree mortality influence post-fire vegetation water cycling, as the rate of water movement from the soil to the atmosphere, depends upon the amount of live vegetation cover in the wake of wildfire. … Read more
