Sensory systems are very susceptible to early environment experience. Mating success depends on the transmission of information from the signaller to the receiver, which means that sensory biases caused by developmental environment are likely to affect sexual selection. We investigated the impact of the developmental visual environment (light spectrum) on male copulation behaviour and female pr...

The impact of anthropogenic eutrophication on the productivity and metabolism of estuarine sediments has received relatively little attention. In this study, we investigated the separate and combined effects of decreased light availability and sediment nutrient enrichment, 2 of the most important impacts of anthropogenic eutrophication, on sediment primary production and metabolism in 2 eutroph...

For satellite remote sensing, radiances received at the sensor are not only affected by the atmosphere but also by the topographic properties of the terrain surface. As a result, atmospheric correction alone does not yield output images that truly reflect terrain surface properties, namely surface reflectance (bidirectional reflectance factor, BRF) of objects on the earth surface. Following the...

Fig. 3: 3D flow characteristics inside the VAD during the peak outflow phase (systole). The gray shaded area represents an iso-surface rendering of the magnitude data and shows the VAD geometry including pump chamber and valve systems at inand outlet. A: A novel valve design using a differently shaped valve support region resulted in improved VAD performance. In addition to improved filling of ...

A standard method of simplifying the task of obtaining a shaded image of a solid object is to represent it by a collection of surface patches or a polyhedron. A smooth shading technique is then applied to each patch/facet to restore smoothness to the image. This paper introduces an entirely new approach to surface representation: the use of isoluminance contours to represent CSG-type primitive ...

We have been using BG-Sentinel (BGS) traps to monitor populations of Aedes albopictus as part of an area-wide project for management of this species. Although BGS traps are very effective for collecting adult Ae. albopictus, the device is expensive and must be properly maintained to be effective. The trap also poses a challenge for mosquito control personnel because secure locations free from t...

The study deals with photophoresis of a spherical micro-particle suspended in absorbing gaseous media. Photophoretic motion of the particle stems from the asymmetric distribution of absorbed energy within the particle. By evaluating the so-called heat source function at various conditions, the study focuses on the effects of governing parameters on the energy distribution within the particle an...

Leaf phenology, growth irradiance (i.e., photosynthetic photon flux (PPF) at the leaf surface) and photosynthetic capacity (A(area); measured at a PPF of 1000 micro mol m(-2) s(-1) and expressed on a leaf area basis) were investigated in early leaves (ELs) and late leaves (LLs) of Betula grossa Siebold & Zucc. trees. Early leaves first appeared on morphologically distinct long shoots and short ...

Provision of shade is recommended by best practice guidelines for horses living in hot, sunny environments despite a lack of research focused on potential benefits. We found in a previous study that horses without access to shade showed greater rectal temperature (RT), respiration rate (RR), and skin temperature (SK) and exhibited more sweat than horses that were completely shaded. Yet not know...

Calluna vulgaris, Molinia caerulea and Pteridium aquilinum are three forest understorey species that compete with tree seedlings for environmental resources. Forest managers therefore seek to control their growth, which is driven in part by the light available in the forest understorey. An experiment was set up in a nursery in which the three understorey species C. vulgaris, M. caerulea and P. ...
