Creative approaches to conservation in a changing world

Autores: Lauren Hallett

Filiación: Biology Department & Environmental Studies Program, University
of Oregon

*Resumen: *In a world of rapid environmental change and loss, scientific
inquiry can point to creative approaches to maintain biodiversity.  Here I
focus on two biodiversity hotspots imperiled by land use and global change
on the west coast of the United States – annual serpentine grasslands in
California and oak-prairie savannas in Oregon – to identify novel ways to
conserve them in the face of ongoing change. By combining a 40-year time
series and experiments in the serpentine, I delineate how rainfall
variability and nitrogen deposition lead to a cyclical, increasing
state-shift from native to non-native species, and how integrating grazing
in the system can halt this transition. By partnering with hazelnut growers
and land managers in former oak-prairie savanna, I find that the
combination of strategic grazing and the use of native species as cover
crops can enhance biodiversity while also benefiting grower operations.

Lauren Hallett, is a plant community ecologist with a goal of producing
“usable” science to improve ecosystem management. She uses a combination of
long-term data analysis, population modeling and field experiments to this
end. Research themes she focus on include: community assembly, functional
traits, species coexistence, ecosystem stability, and resilience theory.
Her research spans a variety of systems, including working rangelands,
serpentine grasslands, woodlands and alpine.

Certificados: los alumnos que necesiten certificar su asistencia, deberán
