Some Energy Issues for a Nanoscale Electrostatic Potential Well in Saline Solutions

Chemosensors, 2020
An electrostatic potential well may be applied to trap and manipulate charged micro- and nanoparticles. An electrostatic potential well obtained from a certain charge distribution may be used to mimic the electrostatic interactions among biomolecules in ...

Surveillance of small rodents and related health risks in a game bird farm

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
Using live trapping devices we performed surveillance of small vertebrates in the game bird farm in Jinačovice in 2005 to 2006. The study was aimed at determining the species composition and numbers within individual technologies of rearing as well as ...

Comparing direct (live-trapping) and indirect (camera-trapping) approaches for estimating the abundance of weasels (Mustela nivalis)

Mammalian Biology
Information on the presence and abundance of a species is crucial for understanding key ecological processes but also for effective protection and population management.

Limitations of invasive snake control tools in the context of a new invasion on an island with abundant prey [PDF]

NeoBiota
In October 2020, a new population of invasive brown treesnakes (Boiga irregularis) was discovered on the 33-ha Cocos Island, 2.5 km off the south coast of Guam.

Wild boar behaviour during live-trap capture in a corral-style trap: implications for animal welfare

Acta Veterinaria Scandinavica, 2020
Background Wildlife traps are used in many countries without evaluation of their effect on animal welfare. Trap-capture of wild animals should minimise negative effects on animal welfare, irrespective of whether the animals are trapped for hunting ...

Genetic sampling for estimating density of common species. [PDF]

, 2017
Understanding population dynamics requires reliable estimates of population density, yet this basic information is often surprisingly difficult to obtain.

Euler buckling in red blood cells: An optically driven biological micromotor

, 2005
We investigate the physics of an optically-driven micromotor of biological origin. A single, live red blood cell, when placed in an optical trap folds into a rod-like shape. If the trapping laser beam is circularly polarized, the folded RBC rotates.

A new live trap for pocket gophers

Wildlife Society Bulletin, 2019
Live‐trapping is important for studying wildlife. In 2016 at Ordway‐Swisher Biological Station in Melrose, Florida, USA, we tested the efficacy of a modified pitfall trap designed to safely and effectively capture southeastern pocket gophers (Geomys ...
