A laboratory study with zebra mbuna and ocellate river stingray has demonstrated that these fish can add and subtract 'one' from 2, 3, or 4. The fish had to learn that if presented with, say, 3 yellow symbols, then in a subsequent choice test between 2 and 4 symbols they had to choose 2 to get a food reward (thus, yellow meant "choose one less ...
The Burnham laboratory was established in 1953 as the Ministry's first-ever purpose-built fisheries laboratory. The role of the laboratory was expanded in 1957 to cover work on pollution, and by the mid-60s began to take the lead in the investigation of environmental protection problems, with the exception of those arising from radioactive ...
Student's t-test, Analysis of variance, Mann–Whitney U test Repeated measures design A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods.
FISH, on the other hand, does not require living cells and can be quantified automatically, a computer counts the fluorescent dots present. However, a trained technologist is required to distinguish subtle differences in banding patterns on bent and twisted metaphase chromosomes. FISH can be incorporated into Lab-on-a-chip microfluidic device ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .
Probe design for CISH is very similar to that for FISH with differences only in labelling and detection. FISH probes are generally labelled with a variety of different fluorescent tags and can only be detected under a fluorescence microscope, [4] whereas CISH probes are labelled with biotin or digoxigenin [5] and can be detected using a bright-field microscope after other treatment steps have ...
The Aquarius Reef Base is an underwater habitat located 5.4 mi (8.7 km) off Key Largo in the Florida Keys National Marine Sanctuary, Florida, United States.It is the world's only undersea research laboratory and it is operated by Florida International University.
A United States Fish and Wildlife Officer works in the forensics laboratory. Wildlife forensic science is forensic science applied to legal issues involving wildlife. Wildlife forensic sciences also deal with conservation and identification of rare species and is a useful tool for non-invasive studies.
