This study describes a step-by-step process used to design an effective benthic video survey component of the Commonwealth of the Northern Mariana Islands long-term monitoring program. Documenting abundance of major benthic groups at relatively large spatial scales, at the appropriate localities, can empower monitoring programs with the capacity to detect changes over time and assess whether ma...

We conducted this study to inves tigate the magnitude of roadway mortality of Lepidoptera in central Illinois. To quantify the number and kinds of Lepidoptera killed along roadways, dead adult Lepidoptera were collected, identified, and counted from along 13 roadside transects in the vicinity of ChampaignIU rbana, Illinois , with collections occurring weekly on each transect for six weeks. Duri...

Isotopic ratios of Sr and Nd from lithogenic components of three isochronous core sections recovered from an east–west transect in the Eastern Mediterranean Sea (EMS) have been analyzed. The data are used for a quantitative estimate of the temporal and spatial variation of detrital flux to the EMS, assuming Saharan dust and Aegean/Nile particulate matter as dominant end members. It was establis...

Some introduced ant populations have an extraordinary social organization, called unicoloniality, whereby individuals mix freely within large supercolonies. We investigated whether this mode of social organization also exists in native populations of the Argentine ant Linepithema humile. Behavioral analyses revealed the presence of 11 supercolonies (width 1 to 515 m) over a 3-km transect. As in...

[1] Many dendroclimatic studies have been conducted in Alaska to understand recent climate changes, identify past and current warming trends, and determine how climate change may influence ecosystems. Four new white spruce (Picea glauca [Moench] Voss) ring-width chronologies from four sites along a 30 kilometer north-south transect in the Lake Clark National Park and Preserve on the Alaskan Pen...

OBJECTIVES The testicular, deferential, and cremasteric arteries and their branches surround the vas deferens (VD), leaving them susceptible to injury during vasectomy. Literature describing the caliber of arteries seen in vasectomy specimens is lacking, making it difficult to categorize the significance of an observed artery. We aimed to establish reference values for arterial size typically e...

Yellow band disease (YBD) has had severe impacts on major reef-building corals throughout the Caribbean. Recent data from Bonaire indicates that this disease remains in an epidemic phase showing similar trends compared to the late 1990s. Ten meter belt transects taken at varied depths of Montastraea spp. indicate high indices of yellow band lesions. At 5m depth, yellow band rings and lesions we...

Line transect sampling is one of the most widely used methods for animal abundance assessment. Standard estimation methods assume certain detection on the transect, no animal movement, and no measurement errors. Failure of the assumptions can cause substantial bias. In this work, the effect of error measurement on line transect estimators is investigated. Based on considerations of the process ...
