Effects Of Aging On The Reproductive Success Of Female Saltmarsh Sparrows (Ammospiza Caudacutus) In Maine And New Hampshire, Isabella Rose Collamati
Honors Theses and Capstones
The saltmarsh sparrow (Ammospiza caudacutus) is a ground-nesting specialist in coastal salt marshes of the Northeast. Rising sea-levels increase the loss of offspring due to tidal flooding, reducing nest success and resulting in a sharp population decline. In other avian species, age has been shown to affect nest success through altering fertility, behavior, and the number of young produced, favoring older individuals. I investigated age effects on nest success of female saltmarsh sparrows using nest monitoring data collected at four sites of a long-term demographic monitoring project: Chapman's Landing (Stratham, NH), Eldridge Marsh (Wells, ME), Popham Beach (Phippsburg, …
Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella
Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella
Honors Theses and Capstones
As the growing human population continues to encroach on wildlife habitat, species are forced to adapt in order to survive. In addition to causing habitat loss, human presence can create more subtle disturbances, such as noise pollution, that disrupt wildlife behavior. Adapting to human presence is particularly difficult for species with specialized resource needs or low mobility. The koala (Phascolarctos cinereus), a national icon of Australia, meets both these criteria. Koalas were once abundant throughout Australia, but are now classified as “threatened.” Habitat loss is at least partly responsible for this decline, but anthropogenic noise may also be …
The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz
The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz
Honors Theses and Capstones
Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant and other adult monkeys. Males preferred to spend time with females without infants but still spent more time with females with infants than with males. Females without infants spent significantly less time with females with infants than with males or other females without infants and females with infants decreased their frequency of social interaction overall without preference for males, females or other females with infants.
