Rabbit bait-take from plastic bait stations
Plastic bait stations were trialled to assess their usefulness as a rabbit control tool. Non-toxic cereal baits were applied at two 171 ha Mackenzie Basin sites, at one site in stations and at the other site spread directly on the ground. Bait-take at each site was measured. Rhodamine-dyed baits were also used to determine the proportion of rabbits at each site that took bait. Bait-take, and th...
متن کاملPrinciples into Practice Setting the Bar for Green Chemistry
R ecent years have seen a disheartening string of revelations in which everyday items once considered safe—food packaging, toys, clothes, furniture, electronic components, and many more products—are found to contain carcinogens, endocrine disruptors, and other harmful chemicals. Growing demand for healthier alternatives, already seen in food production and housing construction, is also happenin...
متن کاملpetrology, mineral chemistry and tectono-magmatic setting of volcanic rocks from northeast farmahin, north of arak
introduction the study area is a small part of the urumieh-dokhtar structural zone in the markazi province, located in the northeastern part of the farmahin, north of arak (hajian, 1970). the volcanic rocks studied from the area include andesite, dacite, rhyodacite, ignimbrite and tuff of middle to late eocene age (middle lutetian to upper lutetian) (ameri et al., 2009). it seems that folding a...
متن کاملCriteria for Rodent Bait Selection
World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Mult...
متن کاملProteomes take the electrophilic bait.
Proteomics researchers are constantly on the lookout for new and better ways to fractionate their samples since the mind-numbing complexity of virtually any proteome easily defeats the ability of even the most advanced mass spectrometers or other instruments to “see” all of the molecules in the sample. In this issue of Nature Chemical Biology, Weerapana et al. report new chemical tools for this...
