Understanding community structure: a data-driven multivariate approach

Abstract: Habitat is known to influence community structure yet, because these effects are complex, elucidating these relationships has proven difficult. Multiple aspects of vegetation architecture or plant species composition, for example, may simultaneously affect animal communities and their constituent species. Many traditional statistical approaches (e.g., regression) have difficulty in handling large numbers of collinear variables. On the other hand, multivariate methods, such as ordination, are well suited to han… Show more

“…This hypothesis is supported by studies that have shown that some groups of birds (Martinsen and Whitham 1994;Poulsen 2002), mammals (Southwell et al 1999;Williams et al 2002), and amphibians (Atauri and Lucio 2001) respond positively to the physiognomic complexity of host plants and, furthermore, by studies that have shown a positive effect of taxonomic diversity of host plant species on the associated communities (Siemann et al 1998;Beals 2006).…”

“…The continental breeding population of lesser scaup reached a record low of 3.2 million in 2006 and has since remained below the goal of 6.3 million set by the North American Waterfowl Management Plan (Austin et al, 2006;USFWS, 2015). A myriad of factors, including habitat loss and degradation, climate change, predation, competition, invasive species and contaminants have been identified as stressors potentially influencing lesser scaup condition and subsequent breeding success (Afton & Anderson, 2001;Anteau & Afton, 2004, 2006Austin et al, 2006;Drever et al, 2012). The Spring Condition Hypothesis suggests that the major contributor to the population decline is reduced recruitment resulting from female lesser scaup reaching their breeding grounds in poor condition (Anteau & Afton, 2004).…”

“…Elucidating fish-habitat relationships has proven difficult (Beals, 2006), and most comparisons have not been statistically robust (Guy and Brown, 2007). Regression analysis is commonly used but has difficulty handling collinear variables (Beals, 2006).…”
