Dinorah Chacin

Dinorah is a doctoral student interested in understanding how spatial components and heterogeneity in seascapes can influence ecological patterns and processes across multiple spatial and temporal scales. Her research seeks to understand how the surrounding seascape can influence communities, species demographic rates, ecological mechanisms, and habitat connectivity. She is currently studying the effects of multiple neighboring habitats (saltmarsh grass, oyster bars, and black mangroves) on the habitat quality of the Eastern Oyster (Crassostrea Virginica). As the habitat range of mangroves expand northward Dinorah seeks to gather insights into whether the replacement of saltmarsh grass habitats with mangroves will benefit, have no effect, or negatively impact the growth and survival of the Eastern Oyster. Dinorah is also investigating the ecological roles of introduced (non-native) and native algal species in East African seascapes. Her goal is to identify which fishes utilize algae as habitats, if any species consume them, and whether there is connectivity between algal beds and other shallow-water habitats. For her research Dinorah incorporates a range of methods including data collection through observations, field-based manipulations, exploration of large data sets using multivariate statistics, and will be using ArcGIS and Stable Isotope of Analysis to further understand habitat connectivity through fish movements.
