Size comparison of quadrats in sample of non-native bivalve Corbicula fluminea (Müller, 1774) (Bivalvia: Corbiculidae)Comparação de tamanhos de quadrats na amostragem do bivalve não-nativo Corbicula fluminea (Müller, 1774) (Bivalvia: Corbiculidae)
(Panamjas, 2013)
We aimed to designate which is the best quadrat area to be used in sampling of C. fluminea for determination of their population parameters. The quadrat of 0.0625 m2 showed the best cost efficiency and a lowest sampling ...
Chilean wine varietal classification using quadratic Fisher transformation
(Springer, 2010)
This paper deals with the Chilean red wine
varietal classification problem. The problem is solved here
by using one of the simplest statistical classification
methods based on quadratic discriminant analysis (QDA)
together ...
Sampling technique affects the population structure assessments of fiddler crab Minuca vocator (Herbst, 1804) (Ocypodidae: Gelasiminae)
(Soc Brasileira Carcinologia, 2016-01-01)
We examined how the sampling technique can affect the evaluation of Minuca vocator (Herbst, 1804) population structure. We used two sampling procedures: catch-per-unit-effort (CPUE) and quadrat technique (QT). Body size, ...
Testing methods to estimate abundance of Magellanic Penguins Spheniscus magellanicus
(Taylor & Francis, 2014-07)
Capsule: Using simulations in a geographical information system our results showed that systematic sampling with quadrats was the most accurate, precise and cost-effective method to survey Magellanic Penguin colonies. ...
