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. ...
Sexual development, size at maturity, size at maternity and fecundity of the blue shark Prionace glauca (Linnaeus, 1758) in the Southwest Atlantic
(Elsevier B.V., 2014-12-01)
Size at maternity and size at maturity of the blue shark Prionace glauca were studied from samples collected during ten commercial longline fishing cruises off southern Brazil and in adjacent international waters. The sharp ...
Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
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, ...
Chelating agent effects in the synthesis of mesoscopic-size superconducting particles
(Springer, 2008-05-01)
Several routes and procedures have been used in these last years as an effort to achieve single-phase mesoscopic-size superconducting samples. In this paper, the effects of using citric acid (CA), tartaric acid (TA) and ...
Assessing the effective sample size for large spatial datasets: A block likelihood approach
(2021)
The development of new techniques for sample size reduction has attracted growing interest in recent decades. Recent findings allow us to quantify the amount of duplicated information within a sample of spatial data through ...
Power of Stable isotope techniques to detect size-based feeding in marine fishes
(Inter-Research, 2010-05)
Stable isotope techniques are now the most frequently applied method to investigate size-based variation in fish trophic position (TP), and data suggest changes in TP with body size are common. However, of 131 collated ...
Capacidade de coleta de três métodos de amostragem e tamanho de amostra para lagartas e percevejos em soja
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-02-16)
This study aimed to compare the caterpillar and stinkbug collection capability of
sampling methods and to determine the sample size (number of sampling points) to estimate
the number of caterpillars and stinkbugs collected ...
