testify
This rule of evidence describes what may qualify a witness as an expert.
Federal rule of 702
on land, TOC is often used as an est. for PMI. What does the TOC estimate in water?
PMSI
the oldest and most ubiquitous form of communication
olfaction
what gene is most commonly used to identify animals to species
CO1
the most common method of analyzing toxicological samples
GC/MS or LC/MS
The tendency to interpret and retain info in a way that strengthens prior beliefs
confirmation bias
One of the only colonizers of buried remains; small and humpbacked flies
chemicals used to communicate between members of the same species
pheromones
genes that encode for specific parts of a body during development
Hox genes
insect evidence is useful for detecting drug absence/presence but not a reliable indicator of:
amount of drug present
specimens maintained as a permanent record of collection and identification
voucher specimens
Larvae of the order of aquatic insect that build casings from immediate surroundings
the class of chemicals responsible for long range detection of decomposition cues by blow flies
volatile organic compounds
TOC est. can be improved by measuring the expression of what?
developmental genes
the effect of stimulant drugs, e.g cocaine, on larval develop. rates
development speeds up
A case built only on circumstantial evidence
straw man argument
Insect evidence is most likely to be found here in a hanging body
Pooled below the body
gustatory chemoreceptors are found where else on a fly other than mouthparts
legs and wing margins
an experiment in which fast developing flies were mated to fast developing flies to produce fly population that grew more quick than normal is an example of...
selection
this technique uses antibodies to detect specific toxins/molecules in a sample
Immunoassay
name the 4 criteria for scientific testimony under daubert standards
known error rates; accepted by scientific community; peer reviewed; testable
Common order of aquatic insects likely to be used in civil investigations regarding water quality
Chironomidae (non-biting midges)
what environmental factors lead to greater dispersal of an order plume? what type of interspecific communication benefits the receiver and is detrimental to the sender?
Wind, increased temp.; kairomone
why is DNA-focused development data not accepted under the daubert standard evidence admissibility?
the error rate is unknown
the proper preservation method for larval samples for toxicological analyses
dry at 4C w/o ethanol
