Longterm Approaches to Assessing Tree Community Responses to Resource Limitation and Climate Variation
… interannual reproductive variation, such as resource matching, predator satiation, and pulse resource dynamics. My results indicate that (1) interannual reproductive variation increased as a result of seed maturation and seed predation processes, (2) seed maturation rates increased under …

The Role of Individual Differences in the Acceptability of Island Violations in Native and Non-native Speakers
… prohibit wh-extraction from islands. Under the resource-limitation theory (Kluender & Kutas, 1993; Hofmeister & Sag, 2010), however, island effects are due to processing difficulty because islands are complex and require additional processing resources that are beyond the capacity of most native …

Behavioural ecology of Peregrine and Lanner falcons in South Africa
… Africa, and examines the relative influence of resource limitation and interspecific competition with congeners on the natural regulation of Peregrine populations in tropical environments.

Moth pollination, low seed set, and vestigialization of attractive floral traits in Abronia umbellata (Nyctaginaceae)
… We integrate this work with tests of pollen and resource limitation of seed production and with seed set surveys of natural populations to address proximate and ultimate causes of low seed set, finding low rates of pollinator visitation, high pollen limitation of seed production in all …

Contraction Analysis of Functional Competitive Lotka-Volterra Systems: Understanding Competition Between Modified Bacteria and Plasmodium within Mosquitoes.
… represent numerous physical phenomena including resource limitation and immune response of a host due to infection. We name this new system a Functional Competitive Lotka-Volterra (FCLV) model. We mainly use the construction of contraction metrics, to determine global properties of the model. We …

A Tale of Three Resources: The Influence of Multiple Resources on Plant-Herbivore Interactions
… that plant growth can be co-limited by multiple resources, particularly water, nitrogen (N), and phosphorus (P), the role of co-limiting resources in driving plant-herbivore interactions remains poorly understood. Evidence indicates that the resources that limit plant and herbivore growth may …

Asymptotic Analysis of Some Stochastic Models from Population Dynamics and Population Genetics
… bounded – size. Populations are kept finite by resource limitation. We show the existence of limits that naturally generalize the weak and strong selection regimes of classical population genetics, which allow the calculation of fixation times and probabilities, as well as the long-term …

Ecology of acidification and recovery in Welsh upland streams
… to test two hypotheses (biotic resistance and resource limitation) proposed to explain the observed delays in faunal recolonisation. A resident-colonist competition experiment revealed no evidence in support of biotic resistance as mediated through interspecific competition, whereas growth …

Extrinsic and Intrinsic Factors Controlling Reproduction in an Annual Plant
… normally would not have matured, suggesting that resources limited fruit production. In four populations studied 24 - 70% of initiated fruits matured, 12 - 40% were aborted or died, 3 - 31% were still developing at the time of plant death, and 6 - 12% were lost to predators. In fruits that …

Influence of Detritus Levels and Organic Pollution on Interspecific Resource Competition, Oviposition Behavior, and Larval Survival of Two Tire-Inhabiting Mosquito Species (Diptera: Culicidae)
… survival of both species, and the effects of resource limitation, interspecific density, and chemical pollution on interspecific competition between both species. I conducted field oviposition bioassays in tires containing different pollution concentrations, and laboratory larval survivorship …

SDN based security solutions for multi-tenancy NFV
… within the cloud environment. Because of resource limitation, the proposed NAC solution was not evaluated. The efficiency of this solution for multitenancy NFV has been added as part of future work.

Freshwater inflows to estuaries : organic carbon and microbial food webs in south-east Australia
… inflow events was the main reason for shifting resource limitation. On both rivers bacterial biomass was positively related to increasing DOC and phosphorus concentrations. Highly episodic discharge during this study had a major structuring role over carbon and bacteria dynamics. On the Bega …

A decision support method for selecting design and manufacturing alternatives
… stakeholders, multiple conflicting criteria, and resource limitation, based on two routes: using Analytic Hierarchy Process (AHP) alone and the combination of AHP with Zero-One Goal Programming (ZOGP). Using AHP-ZOGP allows the concept-concept and concept-specification approaches to be considered …

Predictors of Weight Gain in the Rehabilitation of Eastern North Atlantic Grey Seals (Halichoerus grypus)
… can be compromised before growth when there is resource limitation or stress during the growth phase. Stress has been linked with both weight loss and weight gain in a variety of taxa, and some stressors, such as physical disturbance, are known to affect the development of important …

Concurrent substrate coupling noise modeling and active noise reduction methodology for mixed-signal physical design

Compassion in organizations: sensemaking and embodied experience in emergent relational capability. A phenomenological study in South African human service organizations
… architecture. Situations with limited resources leading to resource exhaustion require further studies to address the risks and liabilities of compassion organizing (Dutton, Worline, Frost, & Lilius, 2006). South African human service organizations face resource limitations within a …

The reproductive biology of four geoflorous Protea species (Proteaceae)
… on P. cordata and P. scabra indicated that resource limitation is prevalent among these plant species. This study adds to the growing knowledge of the reproductive biology of Protea and will improve our ability to reconstruct the history of pollinator shifts in the genus.

Salt in the Wound: Trophic Mismatches Emerge Between Macroinvertebrate Secondary Production and Basal Food Resources Along a Salinity Gradient in Central Appalachian Headwaters
… SC levels (250-500 μS/cm) from enriched food resources and an osmo- and iono-physiological optimum before declining from salt-induced stress in streams with higher SC levels. Additionally, I expected that some shredding and detritivore taxa would increase continuously with increasing SC due to …

MATING COSTS, MALE CHOICE DISPLACEMENT, AND THE EFFECTS ON HYBRIDIZATION AND SPECIATION IN THE HAWAIIAN CRICKET LAUPALA (SUBFAMILY:TRIGONIDIINAE)
… Next, I found that males experience post-mating resource-limitation and show a significant tendency to invest less into a second mating, however, their investment is dependent upon female size. Finally, I found that there is apparent displacement of male choice, decreased variation in …
