The global diversity and distribution of lizard clutch sizes
(Wiley Blackwell Publishing, Inc, 2020-06)
Aim: Clutch size is a key life-history trait. In lizards, it ranges over two orders of mag-nitude. The global drivers of spatial and phylogenetic variation in clutch have been extensively studied in birds, but such tests ...
Correlated evolution of fish host length and parasite spore size: a tale from myxosporeans inhabiting elasmobranchs
(Elsevier, 2022-02)
Myxozoa represent a diverse group of microscopic cnidarian endoparasites alternating between invertebrate and vertebrate hosts. Of the approximately 2,600 species described predominantly from teleost fish, only 1.8% have ...
Ronchi test with variable-frequency rulings
(2009)
We present a new method for testing an optical surface. It uses the Ronchi test with variable-frequency rulings and a liquid-crystal display. The rulings can be formed by substructuring the spacing of a Ronchi ruling or ...
Variação ecogeográfica e funcional do crânio de Tayassuidae (Mammalia: Artiodactyla)
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2018-02-22)
Understanding the determining mechanisms and functional roles of phenotypic variation have been a central topic of ecogeography and evolution. Peccaries are excellent models for testing ecogeographical and functional ...

The peak reproductive activity of Sardinops sagax was determined from surveys carried out by sampling landings from the commercial fleet operating at the port of Guaymas, Sonora, Mexico, from November to March, 1986. Some ...
Variation in vertebral number and its morphological implication in Galaxias platei
(Wiley, 2013-08)
The vertebral number is a major trait of fish structure, related to swimming, feeding, and predator avoidance. The `puyen grande´ Galaxias platei, a big size species of the Galaxiidae family, is a fresh water benthic fish ...
