Point count bird censusing - long term study in central Arizona-Phoenix: Study sites
Project goal: To study the patterns in bird species diversity, abundance and distribution over time and space, and the processes behind these patterns as a result of urbanization. The ongoing project (since October 2000) is documenting the abundance and distribution of birds in four habitats (51 sites): Urban (18) Desert (15) Riparian (11) and agricultural (7). The 40 non-riparian sites are a subset of the CAP LTER Survey200 points. We are using point counts to survey birds four times a year (January, April, July and October). During each session each point is visited by three birders who count all birds seen or heard for 15 minutes. Our goal is to study how different land-use forms affect bird abundance, distribution and diversity in the greater Phoenix area in order to predict and preserve high bird species diversity as urban development is proceeding. This dataset documents only the spatial location of bird survey locations.

Point Count Bird Censusing Data Subset for Paper 'EFFECTS OF LAND USE AND VEGETATION COVER ON BIRD COMMUNITIES' Walker et. al
Animals utilize their environment across a range of scales, which is bounded by their extent, the broadest spatial area which organisms respond to their environment within their lifetime, and the spatial grain, the smallest area they respond to their environment (Kotlier and Wiens 1990). Within this range, organisms likely respond to their environment at a hierarchy of levels. Johnson (1980) recognizes four distinct levels of hierarchical habitat selection. At the very largest scale, first order selection, includes the entire area that an organism utilizes within its lifetime, and is also known as an organisms global home range or extent. In contrast, second order selection is an organisms local home range, or the area that it occupies within a unique ecosystem. This distinction is most apparent with migratory animals who utilize more than one distinct landscape for their survival (i.e. summer vs. winter feeding grounds), and much less so for organisms resident of one specific landscape for their entire life span. Third order selection is the selection of specific habitat patches within an ecosystem. For example, a Monarch butterfly would tend to select patches of milkweed within a prairie. And the lowest level, fourth order selection, involves the physical procurement of food within a selected patch, in our example, specific flowers within a milkweed patch, and is also known as grain. Realizing the importance of hierarchical habitat selection, it has become apparent that single-scale studies of animals responses to their environment may fail to adequately represent how that specific animal is responding to ecological parameter of interest, especially if they are not responding to the landscape at that scale (Holling 1992). The range of scales which an animal of interest is utilizing a landscape is important to determine prior to any further ecological investigation, as inappropriate scalar mismatch between organism and environment can lead to ambiguous or even dece
Lespedeza herbivory census: Arabidopsis BioCON evolutionary study
We know a lot about the potential ecological effects of increasing concentrations to atmospheric CO2; however, we know relatively little about whether increased concentrations will also affect evolution. In collaboration with Jennifer Lau (KBS and Michigan State University), Peter Reich (U of MN Forestry) and Ruth Shaw (U of MN EEB) we are using a combination traditional quantitative genetic and QTL approaches to determine the effect elevated CO2 has on; patterns of selection, responses to selection, and the genetic basis of phenotypic variation.

Figure 3 in Dinosaur Census Reveals Abundant Tyrannosaurus and Rare Ontogenetic Stages in the Upper Cretaceous Hell Creek Formation (Maastrichtian), Montana, USA
Figure 3. Tyrannosaurus (MOR 1125, ''B-rex'') teeth from the lower jaw of this medium-sized skeleton illustrate the extreme range in overall tooth size within one individual. A. A smaller posterior tooth from position #14 from the front of the jaw. B. A larger tooth from position #4 in the same jaw. This demonstrates why shed dinosaur teeth are not a reliable indicator of relative skeletal size and ontogenetic age. doi:10.1371/journal.pone.0016574.g003
Rubble Biodiversity Samplers (RUBS): 3D-printed coral models to standardise biodiversity censuses
<p>1. To ensure standardised, quantitative and repeatable methodologies, marine ecologists have engineered a range of artificial units to survey benthic communities with varying designs depending on target taxa, life history stage and habitat. In tropical ecosystems, autonomous units have typically lacked microhabitat complexity (e.g. planar tiles), short-term efficacy (> 1 y deployment) and/or a truly standardised design to sample cryptobenthic diversity.<br> 2. Coral rubble is characterised by high microhabitat complexity, which is unresolved in sampling efforts. Yet, rubble can support the greatest density and diversity of metazoan taxa.<br> 3. We engineered Rubble Biodiversity Samplers (RUBS) as a dismantlable lightweight 3D-printed model to standardise cryptobenthic biodiversity sampling.<br> 4. We demonstrate the effectiveness of RUBS with preliminary results from short-term (1–14 days) deployments in Palau, Western Micronesia.<br> 5. RUBS uphold the microhabitat complexity inherent in coral rubble (~50% interstitial space) and provide an effective and efficient methodology to sample cryptobenthic fauna, which could be applied in comparative studies.<br> 6. The RUBS concept provides a platform for the broader implementation of 3D-printed models in marine ecology to overcome issues of standardisation regardless of habitat type.</p>
