This project aims to develop a multi-millennial, tree-ring chronology from subfossil trees exposed by retreating glaciers in Southeast Alaska to precisely calendar-date Holocene glacier fluctuations and compare them with a new record of climate seasonality. The multi-millennial tree-ring chronology will be used to extend reconstructions of spring and summer temperatures and build new records of winter storminess by analyzing traumatic resin ducts in annual tree rings. The winter storminess re…

The process of plant domestication is often protracted, involving underexplored intermediate stages with important implications for the evolutionary trajectories of domestication traits. Previously, tomato domestication history has been thought to involve two major transitions: one from wild Solanum pimpinellifolium L. to a semidomesticated intermediate, S. lycopersicum L. var. cerasiforme (SLC) in South America, and a second transition from SLC to fully domesticated S. lycopersicum L. var. l…

Abstract The information an animal gathers from its environment, including that associated with signals, often varies continuously. Animals may respond to this continuous variation in a physical stimulus as lying in discrete categories rather than along a continuum, a phenomenon known as categorical perception. Categorical perception was first described in the context of speech and thought to be uniquely associated with human language. Subsequent work has since discovered that categorical per…

Cave animals are a fascinating group of species often demonstrating characteristics including reduced eyes and pigmentation, metabolic efficiency, and enhanced sensory systems. , an isopod crustacean, is an emerging model for cave biology. Cave and surface forms of this species differ in many characteristics, including eye size, pigmentation, and antennal length. Existing resources for this species include a linkage map, mapped regions responsible for eye and pigmentation traits, sequenced ad…

Variation in pollinator effectiveness may contribute to pollen limitation in fragmented plant populations. In plants with multiovulate ovaries, the number of conspecific pollen grains per stigma often predicts seed set and is used to quantify pollinator effectiveness. In the Asteraceae, however, florets are uniovulate, which suggests that the total amount of pollen deposited per floret may not measure pollinator effectiveness. We examined two aspects of pollinator effectiveness-effective poll…

Floating ice shelves of fast-flowing ice streams are prone to rift initiation and calving originating along zones of rapid shearing at their margins. Predicting future ice-shelf destabilization under a warming ocean scenario, with the resultant reduced buttressing, faster ice flow, and sea-level rise, therefore requires an understanding of the processes that thin and weaken these shear margins. Here, we use satellite data to show that high velocity gradients result in surface troughs along th…

Abstract In this article, I analyse Ferzan Ozpetek's representation of queer narratives within the changing Italian culture and analyse his fusion of accented and cosmopolitan film aesthetics to narrate the hybrid queer and non-queer identities that his characters embody in three of his films: Le fate ignorant (His Secret Life) (2001), Saturno Contro (Saturn in Opposition) (2007) and Mine vaganti (Loose Cannons) (2010). Due to their multicultural nature, Ozpetek's films often represent in-bet…

Project Summary Seminal fluid molecules (SFMs), which are produced by males and transferred to females during mating, have profound impacts on the feeding, reproduction, and lifespan of female insects, including Aedes aegypti and Ae. albopictus, the main vectors of several viruses that are devastating to human health. Identifying the individual bioactive SFMs and their mode of action in Aedes mosquitoes will provide new pathways and tools for stemming disease spread by this species. We have c…
