The greenhouse whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) is a pest of a wide range of vegetable and ornamental crops in greenhouses around the world. Yellow sticky traps are highly attractive to flying adults and so are frequently used to monitor the pest. Our aim was to test whether changes in trap translucency or the addition of printed black patterns could increa...
Many fishers diversify their income by participating in multiple fisheries, which has been shown to significantly reduce year-to-year variation in income. The ability of fishers to diversify has become increasingly constrained in the last few decades, and catch share programs could further reduce diversification as a result of consolidation. This could increase income variation and thus financi...
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined with a high stocking density of cows, means this potentially leads to large amounts of urinary nitrogen (N) deposited on bare, wet soil, that in turn, could lead to high nitra...
The CATCH (Community Access to Child Health) Program, which supports pediatricians who engage with the community to improve child health, increase access to health care, and promote advocacy through small seed grants, was last evaluated in 1998. The objective was to describe the characteristics of CATCH grant recipients and projects and assess the community impact of funded projects. Prospectiv...
Conservation and Management Measure 2008‐06 was implemented by the Western and Central Pacific Fisheries Commission in February 2009 and requires the Commission to work toward providing preliminary advice on the stock status of key shark species in 2010. While the need for shark assessments is thus well‐recognised, catch data necessary to support such assessments is, in many cases, insufficien...
This is the first assessment of catch rates for the legal, artisanal green turtle, Chelonia mydas, fishery in Caribbean Nicaragua. Data were collected by community members, monitoring up to 14 landing sites from 1991 to 2011. We examined take levels, and temporal and spatial variability in catch rates for the overall fishery, by region, and community using General Additive Mixed Models (GAMMs)....
This study investigated the movement preparation (reaction time) and movement execution (movement time) of children with and without ADHD by manipulating the uncertainty of occurrence. Participants performed a seated lower extremity choice response time protocol, which contained either 10% catch trials or 30% catch trials along with 27 empirical stimuli to one of three target directions. Result...
OBJECTIVE Catch-up growth, a risk factor for later type 2 diabetes, is characterized by hyperinsulinemia, accelerated body-fat recovery (catch-up fat), and enhanced glucose utilization in adipose tissue. Our objective was to characterize the determinants of enhanced glucose utilization in adipose tissue during catch-up fat. RESEARCH DESIGN AND METHODS White adipose tissue morphometry, lipogen...
The attraction of adult Chironomus salinarius to incandescent 3-W lamps of 7 different colors used in CDC traps was studied on a small island in the lagoon of Venice, Italy. An ANOVA indicated that the lamp type was a highly significant (P < 0.01) factor associated with differences in light trap catch (28% of total variation), as well as catch per lux (18% of total variation). The white lamp at...
Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery for the nationally red-listed European lobster (Homarus gammarus) in south-eastern Norway. Probability-based strip transect surveys were used to count buoys in the study area in...
