- The Effect of Sea Level Rise on Juncus roemerianus’s Ability To Remain An Environmental Restoration Indicator Species.
- Creator
- Abbott, Cara J., Berry, Leonard, Graduate College
- Abstract/Description
-
Juncus roemerianus, the black rush, has long been used in restoration projects in south Florida because of its unique ability to live in both freshwater and saltwater. In particular, it has been used as an indicator of salt-water incursion due to its differing physical forms in varying levels of salinity. When found in freshwater, it can reach heights over 2.1 meters, yet when found in hypersaline water, it becomes dwarfed and only 1 meter in height. Because of its dramatic differences in...
Show moreJuncus roemerianus, the black rush, has long been used in restoration projects in south Florida because of its unique ability to live in both freshwater and saltwater. In particular, it has been used as an indicator of salt-water incursion due to its differing physical forms in varying levels of salinity. When found in freshwater, it can reach heights over 2.1 meters, yet when found in hypersaline water, it becomes dwarfed and only 1 meter in height. Because of its dramatic differences in physical appearance due to salinity, it has provided an easy and fairly cheap method of determining an area’s localized salinity level. Most of Juncus roemerianus’s range in Florida lies around the coasts, which most models predict will experience significant changes due to sea level rise in the not so distant future. The purpose of this study is to determine whether the black rush can remain an environmental restoration indicator species in conditions influenced by sea level rise. This study will take place in the FAU Boca greenhouse and will target increased water levels and increased pH as the main conditions affected by sea level rise. If this study finds that increased water levels and pH do not significantly change the appearance of Juncus roemerianus in varying salinity, then this plant can confidently remain an indicator of salt-water incursion in the future. Conversely, if these conditions do change the appearance of Juncus roemerianus, then this plant may not remain an indicator species in South Florida in the future.

Climate change is causing shifts in species geographic distributions. This trend is seen throughout the globe but the impact is especially noticeable in marine environments, which are highly sensitive to phenological and ecological alterations. Here, systemic shifts have cascading effects on the food web, productivity, and event timing.

Show moreClimate change is causing shifts in species geographic distributions. This trend is seen throughout the globe but the impact is especially noticeable in marine environments, which are highly sensitive to phenological and ecological alterations. Here, systemic shifts have cascading effects on the food web, productivity, and event timing. Throughout the tropics and the subtropics, mangrove trees act as the primary foundation species that dominate the intertidal zone. In particular, red mangroves Rhizophora mangle play a crucial role by acting as substrate for sessile species within their ecosystems. In these ecosystems, secondary foundation species that can colonize the prop roots of the red mangroves thereby further affecting the structure of the community. The original habitat architecture limits species variety and the effectiveness of species to utilize the space. Habitat architecture is strongly influenced by the foundation species that form the base for community structure. Investigating the connections between a primary foundation species, secondary foundation species, and the resulting biodiversity of sessile species is critical to understanding the variability of the ecosystem. Association with certain foundation species may provide a more positive environment for certain taxa than others and thus ease stressors that otherwise could functionally eliminate a species from the ecosystem. In addition, these associations can have cascading effects on neighboring species and neighboring ecosystems. Here, we conducted a presence/absence survey from Key West to the Kennedy Space Center to identify the species that utilized mangrove prop roots as habitat, their associations, and distributions.

Show moreThe rodent hippocampus is an essential neural substrate for spatial memory. This functional capacity is considered to rely upon a cognitive map that represents the location where relevant non-spatial items or objects are encountered and where specific events occur within a contextual or spatial reference frame. Place cell activity recorded from CA1 pyramidal neurons of the dorsal hippocampus of freely moving rodents is influenced by distal and proximal cues or items within an environment, and increases when objects are placed into a familiar arena. Recently, the CA1 region of the rodent dorsal hippocampus was shown to play a vital role in object-in-context memory, and object memory independent of context; findings consistent with the cognitive map view. Here, we tested the influence of 3D objects on the spatial firing properties of CA1 neurons, since object-specific neuronal activity has not yet been fully established in mouse hippocampus. In vivo extracellular recordings from intermediate dorsal CA1 yielded simultaneous recordings of place cells and a pyramidal neuron demonstrating object-specific activity over two consecutive sessions with objects present. Higher frequency object-specific activity was recorded from the same mouse again 3 weeks later during a comparable task. Object-specific activity was observed only when the mouse explored objects in the arena, and was independent of spatial location or object identity. Recordings from more distal region of dorsal CA1, which receives input from proximal CA3, yielded two additional neurons that demonstrated comparable object-related activity. These results further support the involvement of the rodent hippocampus in non-spatial object memory.

- Inhibition of Emotions as a Moderator of the Relationship Between Victimization Experiences and Aggression in Preadolescence.

- Abstract/Description
-
Chronic victimization by peers sometimes fosters aggression in children (Dodge, 2011; Hodges & Perry, 1999). Recent data suggest that cross-gender victimization is more common in girls during middle childhood (Benbenishty, & Astor, 2005). That is, girls are picked on by boys at a proportionally higher rate than boys are picked on by girls. However, the possibility that enduring cognitive structures moderate effects of victimization on aggression—by serving as processing filters through which...
Show moreChronic victimization by peers sometimes fosters aggression in children (Dodge, 2011; Hodges & Perry, 1999). Recent data suggest that cross-gender victimization is more common in girls during middle childhood (Benbenishty, & Astor, 2005). That is, girls are picked on by boys at a proportionally higher rate than boys are picked on by girls. However, the possibility that enduring cognitive structures moderate effects of victimization on aggression—by serving as processing filters through which children perceive, interpret, and respond to the adverse experiences—remains unexplored. In this study, we assessed whether victimization experiences at the hands of the other sex increased aggression over the school year. We measured peer-nominated aggression toward the other sex and victimization by the other sex in 195 children (94 girls, 101 boys; M age 10.1 years). We also examined self-reported inhibition of emotions as a possible moderator. Results suggest that aggression did not increase over time if boys were victimized by other boys, but the more that boys were victimized by girls, the more their aggression increased girls’ aggression was unaffected by victimization by peers of either sex as a main effect. However, inhibition of emotions moderated the effect of victimization on aggression in both sexes. Thus, the experience of being victimized by the other sex led to an increase in aggression toward the other sex only when inhibition of emotions was high, rather than low. These findings highlight the importance of examining interactive models that contribute to aggression in children.
