Woody plant richness and landscape preference
… explores how greenness levels and tree species richness affect preference for neighborhood landscapes. I conducted a systematic assessment of greenness and biodiversity and designed multiple virtual reality landscape simulations as alternatives to traditional photo and video methods of exploring …

Species richness and metacommunity dynamics in bryophytes
Bryophyte species richness and composition were analysed on limestone boulder habitats across twenty sites in Malta. These boulders acted as standard units for studying the effect of environmental, microtopographical and spatial factors on bryophyte metacommunities. The results indicated that …

Mixed Media Richness and Computer-Mediated Communications
Mixed richness communications occur when a participant in a conversation receives a different media or combination of media than they transmit. Mixed richness communications occur in the workplace when technical, physiological or practical limitations prevent the use of the same media on both ends …

Tropical Pyramids: Dung Beetle Richness, Abundance, and Biomass
… geologically young Amazon (P < 0.0001). Species richness (P = 0.0002), Chao 1 (P = 0.0003), Fisher’s (P = 0.008) and Margalef indices (P = 0.0003) were greater on young soils. Menhinick (P = 0.54), Simpson (P = 0.54) and rarefied species richness (P = 0.24), which correct for sample size …

Floral richness inventory of an eastern U.S. forest
… were sampled for vascular plant species richness. Two-hundred and forty-eight species were identified. Three methods of sampling for species richness in eastern forests were compared: timed-search meanders, belt transects, and plots. Meanders and transects located more species in the same …

Tradition richness : a theory of campus traditions and culture.
… an interdisciplinary theory of tradition richness, approaching traditions as a form of interaction ritual. This theory is then clarified through a collective case study of five governing members of the Council for Christian Colleges & Universities. The findings from this study reiterated …

Microcelebrity Practices: A Cross-Platform Study Through a Richness Framework
… The first phase of the study relied on a richness scoring framework that quantified social media activities using affordance richness, a measure of the ability of a post to deliver the information necessary in affording a celebrity to perform an action by using social media artifacts. The …

Enhancement of Floral Species Richness in Glaciated Prairie Temporary Wetlands
… Region wetlands frequently recover plant species richness resembling undisturbed conditions. However, plant species richness in temporarily flooded wetlands often recovers poorly due to colonization by aggressive undesirable species. This study was conducted during 1995 and 1996 in eastern South …

A Deeper Semiotic Richness: Empowering English Language Students Through Digital Storytelling
<p>The current philosophies underpinning TESOL higher education curricula and classroom practices still reinforce the essentialized narrative of the <em>native speaker</em> and teach English as an objective, disinterested, linguistic system of static signs (Blommaert, 2010; Kramsch, 2009; …

Species richness and composition of avifaunal communities in a complex Amazonian landscape
… This study aimed to identify how species richness and composition of avifaunal communities in the lower Rio Purús region of central Amazonia compare across terra firme, whitewater and blackwater seasonally flooded forests and their seasonal variation in water levels. Avifauna was sampled …

Wetland Condition Matters: Amphibian Richness and Abundance Change Across Wetland Condition Gradient
… via dipnetting and minnow-trapping. Species richness and abundance were tested with AIC modeling using nutrients, dissolved oxygen, landscape disturbance, presence of predatory fish, the pesticide atrazine, and KY-WRAM scores as model parameters. Results indicated KY-WRAM score explained the …

Vertebrated Richness of Waterfowl Production Areas in the Prairie Pothole Region of Minnesota
… or lodges. Diversity was measured using species richness. While it appeared to have the highest species richness, the Border Prairie region was not significantly different from other regions. Species richness was directly related to WPA size. If diversity is a management goal, managers should …

The spatial modelling of high-latitude plant richness and refugia in a changing environment
… refugia; investigates drivers of plant richness and how projected hotspots coincide with conservation areas; forecasts refugia for species persistence and their connection to topo-geological features; and predicts forthcoming changes in species distributions and sensitivity, and whether …

Modelling British Columbia’s ecosystems and avian richness using landscape-scale indirect indicators of biodiversity
… indicators for the indirect mapping of species richness and ecosystem components modelling the processes controlling species distribution gradients. The goal of our research is to advance broad-scale biomonitoring by demonstrating how landscape-scale environmental indices can be used to model …
