In the Amazon region the phlebotomine fauna is considered one of the most diverse in the world. The use of Shannon traps may provide information on the anthropophily of the species and improve the traps' performance in terms of diversity and quantity of insects collected when white and black colored traps are used together. This study sought to verify the attractiveness of the traps to the phle...

We present the design and experimental analysis of a dielectrophoretic trap composed of four microfabricated gold posts excited in a quadrupolar fashion. Using quantitative modeling tools, we have designed these extruded traps to attain strong holding against flow while being constrained by a set of system parameters. The extruded geometry consists of cylindrical electrodes in a trapezoidal arr...

Humans are altering the environment at an unprecedented rate. Although behavioural plasticity has allowed many species to respond by shifting their ranges to more favourable conditions, these rapid environmental changes may cause 'evolutionary traps', whereby animals mistakenly prefer resources that reduce their fitness. The role of evolutionary traps in influencing the fitness consequences of ...

We present an overview of recent results for the classic problem of the survival probability of an immobile target in the presence of a single mobile trap or of a collection of uncorrelated mobile traps. The diffusion exponent of the traps is taken to be either γ = 1, associated with normal diffusive motion, or 0 < γ < 1, corresponding to subdiffusive motion. We consider traps that can only die...

Restraining is essential to many wildlife research and management programs. In an Argentine Pampas area, we studied the trapping success for the pampas fox Pseudalopex gymnocercus. We compared the capture efficiency (captures/trap days), species selectivity (fox captures/all captures), trap reliability (fox captures/fox visits), and malfunction rate (disturbed traps/trap days, of three restrain...

BACKGROUND This is the third in a series of papers detailing the terrestrial arthropods collected during an intensive survey of a site near Steel Creek campground along the Buffalo National River in Arkansas. The survey was conducted over a period of eight and a half months using twelve trap types - Malaise traps, canopy traps (upper and lower collector), Lindgren multifunnel traps (black, gree...

In the manuscript we presented transient photocurrent simulations with rise and decay. Here we analyse the same TPC decay in detail. Figure S1 shows simulation results of the transient photocurrent decay for all cases defined in Table 1 in the manuscript. With a lower mobility (b) the decay is slower because it takes longer until the device is empty. In the case ‘deep traps’ (c) the current sho...

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a serious invasive pest of North American ash (Fraxinus spp.) that has caused devastating mortality since it was first identified in North America in 2002. In 2012, we conducted field trapping assays that tested the efficacy of purple prism and fluon-coated green multifunnel (Lindgren funnel) traps. Traps were ba...

Diffusion and reaction processes control the dynamics of many different biological systems. For example, tissue respiration can be limited by the delivery of oxygen to the cells and to the mitochondria. In this case, oxygen is small and travels quickly compared with the mitochondria, which can be considered as immobile reactive traps in the cell cytoplasm. A Monte Carlo theoretical investigatio...

OBJECTIVE To determine the time and financial costs of programs for live trapping feral cats and determine whether allowing cats to become acclimated to the traps improved trapping effectiveness. DESIGN Prospective cohort study. ANIMALS 107 feral cats in 9 colonies. PROCEDURE 15 traps were set at each colony for 5 consecutive nights, and 5 traps were then set per night until trapping was ...
