Redesigning octopus traps

open access: yesFrontiers in Marine Science, 2014
Octopus, squids, lobsters, cuttlefish, etc., are traditionally caught with traps that are placed in the seabed for several months. Nowadays, the traps (Covos) used in the North of Portugal are made of a rigid structure of cast iron covered with a 152 to ...

Effects of Aprons on Pitfall Trap Catches of Carabid Beetles in Forests and Fields [PDF]

open access: yes, 2017
This study compared the efficacy of three types of pitfall traps in four forest and two field habitats. Two traps had aprons and one did not. The two apron traps were the same except for a gap between the trap and the plywood-apron, allowing captures ...

Trapped Surfaces [PDF]

open access: yesInternational Journal of Modern Physics D, 2011
I review the definition and types of (closed) trapped surfaces. Surprising global properties are shown, such as their "clairvoyance" and the possibility that they enter into flat portions of the spacetime. Several results on the interplay of trapped surfaces with vector fields and with spatial hypersurfaces are presented.

Optical trapping [PDF]

open access: yesReview of Scientific Instruments, 2004
Since their invention just over 20 years ago, optical traps have emerged as a powerful tool with broad-reaching applications in biology and physics. Capabilities have evolved from simple manipulation to the application of calibrated forces on—and the measurement of nanometer-level displacements of—optically trapped objects.

Attractiveness of black Shannon trap for phlebotomines

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
A white Shannon-type trap was used for captures of female sand flies in the search for natural infection with flagellates, however, due to its low productivity and as a large number of phlebotomines settled on the researchers' black clothes, we decided ...

Attraction of Acorn-Infesting \u3ci\u3eCydia Latiferreana\u3c/i\u3e (Lepidoptera: Tortricidae) to Pheromone-Baited Traps [PDF]

open access: yes, 2017
Males of acorn-infesting Cydia latiferreana are attracted to an equilibrium mixture of the four isomers of 8, 10-dodecadien-l-ol acetate, the virgin female-produced pheromone. Trap height relative to the height of trees in which traps are placed seems to

Field Evaluation of Trap Components for the Introduced Pine Sawfly, \u3ci\u3eDiprion Similis\u3c/i\u3e (Hymenoptera: Diprionidae) [PDF]

open access: yes, 2017
Three sizes of the Conrel Delta trap, a yellow cardboard tube trap, and the Pherocon II standard trap generally used in detection surveys were evaluated. Tests were run for 41 days in the summer of 1980 and 35 days in the spring of 1981.

The Changing Role of Rodenticides and Their Alternatives in the Management of Commensal Rodents

open access: yesHuman-Wildlife Interactions, 2019
Rodents cause substantial damage and losses of foodstuffs around the world. They also transmit many diseases to humans and livestock. While various methods are used to reduce damage caused by rodents, rodenticides remain an important tool in the toolbox.
