I'm examining nest survival and ecology of white-tipped doves in the Lower Rio Grande Valley of south Texas. White-tipped doves are an extremely elusive and understudied gamebird that can be found from Argentina north into the subtropical LRGV. We are currently using real-time, infrared camera systems to identify nest predators and capture parental behavior. We have located nests in both remnant woodland and citrus agriculture and are currently developing survival models.
Depletion of soil microbial communities has detrimental effects on the entire ecosystem. Throughout Texas, mesquite trees (Prosopis glandulosa) and Texas wintergrass (Nassella leucotricha) have invaded and altered the production and diversity of native grasses. Why do they occur together? How are they changing the soil microbiome?
My research focuses on the microbial community in the soil of each of these species, hoping to find a similar community structure so as to explain the mesquite-Texas wintergrass association. I collected soil samples from beneath mesquites (with and without wintergrass) and wintergrass (under and beyond the canopy), as well as other grasses for a comparison control. The samples will be subjected to 16S metagenomics analysis (DNA sequencing) to compare microbial community structures between the two species.
Amber is researching the movement and distribution of phosphorus in soil profiles. Large livestock operations, such as confined animal feeding operations and dairies, dispose of waste by applying it to the land in quantities that result in excess phosphorus. This can move to water bodies, where it becomes a major pollutant. Amber's research aims to increase our understanding of the way phosphorus behaves in Texas soils, with the goal of helping farmers dispose of livestock waste without harming water resources.
