Understanding climate change effects in alpine meadows: harnessing the power of data science, and remote sensing
Montane ecosystems are particularly sensitive to climate warming. This is because Alpine wildflowers that are dominant in these ecosystems are prone to local level extinction (as suitable habitats disappear), as spring ... -
Using yeast to trace a history of expanding auxin signals
Auxin is a hormone that plays essential roles in almost all growth and developmental processes across allplants. The way cells interpret responses to auxin is regulated by the auxin signal transduction pathway - a tangled ... -
Vernal migratory behavior in captive white-crowned sparrows, Zonotrichia leucophrys
(2008)Avian migration, the biannual movement of birds from non-breeding to breeding grounds, is a global phenomenon that has fascinated scientists for centuries. The presence of seasonal unrest in caged birds coincident with ... -
Vertebrate patterns of taxonomic and ecological diversity and recovery from the End-Permian Mass Extinction: two novel test cases from southern Pangea
Mass extinctions are among the most important events in the history of life on Earth and understanding their effects on life and the structure of biotic systems is restricted to the fossil record. Comparatively few studies ... -
Visual learning and processing in the honeybee, Apis mellifera
The honeybee, Apis mellifera, is well-known for her crucial role in crops pollination and for producing an highly-appreciated food, the honey. Indeed, the first historical record of bee-keeping dates from the Mesolithic ... -
The what, when & how of seedling growth regulation.
(2013-07-23)Photomorphogenesis has two stages. First, seedlings detect light and open their embryonic leaves (cotyledons). Second, seedlings optimize their light environment by regulated elongation of the embryonic stem (hypocotyl). ... -
Why sink strength is a key determinant of drought tolerance in common bean
Throughout development, plants are constantly shifting resource allocation between their different tissue types; roots, stems, leaves, fruits and seeds. This allows them to balance resource gain, optimize growth, and ... -
Wing flexibility and design for animal flight
(2002)The wings of flying animals change shape dramatically during flight, yet the control and effects of these shape changes have received little attention. In Chapter 1, I discuss the potential effects of wing flexibility and ...
