New insights to discriminate between Sympterygia acuta Garman 1877 and Sympterygia bonapartii Müller & Henle, 1841 (Rajidae) of the Southwest Atlantic Ocean: On the use of geometric morphometrics and spinulation patterns
(Wiley Blackwell Publishing, Inc, 2015-04)
Geometric-morphometric and spinulation pattern approaches were employed to assess the discrimination of two species of Sympterygia skates in the Southwest Atlantic: Sympterygia acuta Garman 1877 and Sympterygia bonapartii ...
Restricted versus step-up dietary adaptation in Nellore bulls: Effects over periods of 9 and 14 days on feedlot performance, feeding behavior and rumen morphometrics
(2019-01-01)
Previous studies have shown that beef cattle can be adapted for 14 days to high-energy diets; however, the effects of adaptation periods less than 14 days on feedlot performance have not been documented in the literature. ...
Testing repeatability, measurement error and species differentiation when using geometric morphometrics on complex shapes: a case study of Patagonian lizards of the genus Liolaemus (Squamata: Liolaemini)
(Wiley Blackwell Publishing, Inc, 2020-07-14)
The repeatability of findings is the key factor behind scientific reliability, and the failure to reproduce scientificfindings has been termed the "replication crisis". Geometric morphometrics is an established tool in ...
Geometric estimates of heritability in biological shape

Unsupervised techniques for shape analysis of Iberian ceramics based on Geometric Morphometrics
(Jagiellonian University in Kraków, 2019)
The morphological analysis of ceramic pieces allows to establish the chronology, functionality and origin of the samples. The conformation of a typology of ceramic materials is made by analysing several aspects, such as ...
Larval anatomy of Andean tadpoles of Telmatobius (Anura: Ceratophryidae) from Northwestern Argentina
(MAGNOLIA PRESS, 2008-12)
In this paper I study the oral, buccopharyngeal, and musculoskeletal configuration in tadpoles of nine Telmatobius species from Northwestern Argentina (T. atacamensis, T. ceiorum, T. laticeps, T. oxycephalus, T. pinguiculus, ...
Ecomorfología alimentaria de algunas especies de peces asociadas a fondos blandos
(2010-01-26)
RESUMEN: La ecomorfología es la disciplina que estudia la interacción entre la diversidad morfológica y la ecológica, explicando los mecanismos por los cuales las variaciones morfológicas entre individuos resultan en ...
Effects of restricted vs. step up dietary adaptation for 6 or 9 days on feedlot performance, feeding behaviour, ruminal and blood variables of Nellore cattle
(2018-02-01)
This study was designed to determine effects of quantitatively restricted intake of the final finishing diet as a means of dietary adaptation compared with diets increasing in concentrate (step up) over periods of 6 and 9 ...
