Sensory exploitation in a sit-and-wait predator: Exploring the functions of stabilimenta in the banded garden spider, Argiope trifasciata
Attracting prey by exploiting a visual sensory bias is a common theme in stationary predators across many taxa, particularly for obligate ambush predators, such as orb-weaving spiders, because they construct complex prey ...
Exploring the Functional Significance of the Caenorhabditis elegans VAB-1 Eph RTK and DAF-18/PTEN Tumour Suppressor Interaction
The Caenorhabditis elegans Eph RTK, VAB-1, has known roles in neuronal and epidermal morphogenesis as well as oocyte maturation through interaction with its ephrin ligands. In humans, Eph receptors are involved in nervous ...
Targeted over-expression of hsp22 and the maintenance of locomotor activity of third instar larvae of Drosophila melanogaster at high temperatures
Hsp22 has been implicated in stress tolerance and longevity in various organisms though its role in Drosophila melanogaster larval thermal tolerance has not yet been investigated. I undertook this project to determine if ...
Limnological and paleolimnological investigations of environmental change in three distinct ecosystem types, Canadian High Arctic
The biological remains preserved in the sediments of Arctic lakes and ponds in the Canadian High Arctic are important indicators of environmental change, especially as long-term instrumental data are often lacking. Although ...
Delayed maturation of secondary sexual signals in first-year male American redstarts
Male birds of many species use conspicuous song and plumage displays in both courtship and territorial interactions. In some species, one or both of these signalling traits may not reach full adult maturity until a male’s ...
Making Sure Hungry Plants Get Fed: The Dual-Targeted Purple Acid Phosphatase Isozyme AtPAP26 is Essential for Efficient Acclimation of Arabidopsis Thaliana to Nutritional Phosphate Deprivation
Acid phosphatases (APases; E.C. 22.214.171.124) catalyze the hydrolysis of phosphate (Pi) from Pi monoesters and anhydrides within the acidic pH range. Induction of intracellular and secreted purple acid phosphatases (PAPs) is a ...
