Seagrass Community Change At Three High Risk Ports In The Great Barrier Reef World Heritage Area From 2005 To 2014, Celeste Venolia
Seagrass Community Change At Three High Risk Ports In The Great Barrier Reef World Heritage Area From 2005 To 2014, Celeste Venolia
Independent Study Project (ISP) Collection
Seagrass meadows are extremely valuable and dynamic ecosystems currently facing pressure from anthropogenic disturbances. Seagrass ecosystems are declining globally because of direct and indirect threats that shift environmental conditions controlling seagrass distribution. Seagrass species responses to disturbances vary based on a number of factors including life history strategy. The goal of this study was to map and analyze patterns of dominant seagrass species change at Cairns and Gladstone from 2005-2014 and Townsville from 2007-2014. This compilation data set was symbolized according to the life history strategy of the species. The major disturbances during this time period were physical damage from …
Effect Of Varied Disturbance Types On Dorylus (Anomma) Molestus Defensive Behavior In The West Usumbara Mountains, Tanzania., Ryan Mahar
Independent Study Project (ISP) Collection
The purpose of this study was to observe novel nest characteristics of Dorylus molestus (Siafu), as well as their defensive behavior in response to varied disturbance methods. The number of defensive soldiers at a specific section of a column was counted before and after each agitation. Varied agitation methods were used on columns without larvae presence to test how soldiers responded to different disturbance types. Disturbances on columns with larvae presence were compared to those on columns without larvae. Nest distribution, behavior, composition, and size were observed objectively. Mechanical disturbance was found to incite the greatest increase in defensive soldier …
