Survival analysis of tethered juvenile sea scallops Placopecten magellanicus in field experiments: Effects of predators, scallop size and density, site and season
(1994)The impact of predation on survival of juvenile sea scallops Placopecten magellanicus has important implications for the population dynamics and aquaculture of this species. In field experiments using tethered juvenile ... -
Surviving historical Patagonian landscapes and climate: molecular insights from Galaxias maculatus
(2010-03)Background: The dynamic geological and climatic histories of temperate South America have played important roles in shaping the contemporary distributions and genetic diversity of endemic freshwater species. We use ... -
Sustainability Education Initiatives for University Staff: A Case Study from Dalhousie University
(2024-04)Universities play a pivotal role in fostering sustainability practices through education and operation. Considerable attention has been given to integrating sustainability into curricula to engage students; however, there ... -
Sustainable Furniture Procurement at Dalhousie University
(2012-04)Research was conducted by 5 Dalhousie Students in the SUST 3502 Campus as a Living Laboratory Course pertaining to sustainable furniture procurement at Dalhousie. The current problem at Dalhousie lies in the lack of overall ... -
Sustainable Grounds Management at Dalhousie University: A Community Approach
(2006-04)There is a need for greater sustainability on Dalhousie University campuses. More specifically, the report epands on the need for sustainability in terms of the land indicators on campus. Dalhousie’s current landscape ... -

Symmetry, change, perturbation, and observing mode in natural communities
(1986)Like a kaleidoscope, nature presents continuously fleeting images of natural communities. It has been difficult to discern patterns of community structure in these elusive images. For both theoretical and applied considerations, ... -
Synchronized hatch and its ecological significance in rainbow smelt Osmerus mordax in St. Mary's Bay, Newfoundland
(2004-11)Early life history stages in most marine animals are subject to high mortality through predation, starvation, and dispersal. Accordingly, the potential exists for the selection of behavioral mechanisms that reduce ... -
Synconvergent ductile flow in variable-strength continental crust; numerical models with application to the western Grenville Orogen
(American Geophysical Union, Washington, DC, 2007-10)No abstract available. -
Synthesis and Anticancer Activity of Prodigiosenes bearing C-Ring Esters and Amides
(Royal Society of Chemistry, 2017) -
Synthesis and Antimalarial Activity of Prodigiosenes
(Organic and Biomolecular Chemistry, 2014)Several analogues of the natural compound prodigiosin with modified A- and C-rings were synthesised as were some of their tin, cobalt, boron and zinc complexes. The antimalarial activity of these prodigiosenes was evaluated ... -
Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen
(Bioorganic & Medicinal Chemistry, 2013)To generate the first series of prodigiosene conjugates, the tripyrrolic skeleton was appended to estrone, tamoxifen and porphyrin frameworks by way of ester linkers and various hydrocarbon chain lengths. The ability of ... -
Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework
(2013)An improved and scalable synthesis of the unsubstituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a- ... -
Synthesis and Characterization of Pyrrolyldipyrrin F-BODIPYs
(Photochemical and Photobiological Sciences, 2018)A series of synthetic analogs of the tripyrrolic natural product prodigiosin were complexed with boron trifluoride to generate the corresponding F-BODIPYs. The maximum wavelengths of absorption and emission of the ... -
Synthesis and reactivity of 2-thionoester pyrroles: a route to 2-formyl pyrroles
(RSC Advances, 2019)2-Functionalised pyrroles exhibit considerable synthetic utility. Herein, the synthesis and reactivity of 2-thionoester (-C(S)OR) pyrroles is reported. 2-Thionoester pyrroles were synthesized using a Knorr-type approach ... -
Synthesis and Reactivity of Aza-Dipyrrin Alkali Metal Salts
(Chemical Communications, 2018)We report the lithium, sodium and potassium salts of aza-dipyrrins and detail their use as anionic aza-dipyrrinato ligand sources in complexation. Of the three types of alkali salts studied, those of lithium are found to ...
