Linden (Tilia spp.), a profusely flowering temperate tree that provides bees with vital pollen and nectar, has been associated with bumble bee (Bombus spp.) mortality in Europe and North America. Bee deaths have been attributed, with inadequate evidence, to toxicity from mannose in nectar or starvation due to low nectar...
Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...
Benefits humans rely on from the ocean - marine ecosystem services - are increasingly vulnerable under future climate. This paper reviews how three valued services have, and will continue to, shift under climate change: (1) capture fisheries, (2) food from aquaculture, and (3) protection from coastal hazards such as storms...
Domestic cats have been shown to form secure attachment bonds with humans, allowing them to use their owners as a secure base and giving them comfort and confidence when exploring an unfamiliar environment. Many cat owners believe that cohabitation with other cats is beneficial for their pets, and that cohabitant...
The transition to kindergarten can be challenging for many children who do not have the necessary skills to meet the demands of classroom settings such as paying attention, remembering instructions, and demonstrating self-control. Children who lack the necessary behavioral regulation skills to meet the demands in the classroom environment are...
Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...
Domesticated cats frequently use their sense of smell to navigate their environment, convey social cues, and communicate with other individuals. In applied contexts, cat owners are often encouraged to leave items holding their scent with their cat in periods of absence with the aim of reducing stress. The purpose of...
This thesis employs a narrative analysis of more than twenty-five films that are
centrally concerned with immigrants and the immigrant experience. In Part One,
drawing from the work of Yosefa Loshitzky, I will focus on films that feature an
immigrant lead character. In Part Two, I will explore movies that...

Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...
