Girdling of shoots at flowering reduces shatter in grapevine cv. Malbec
(Wiley Blackwell Publishing, Inc, 2020-04)
Background and Aims: Some grapevine cultivars such as Malbec have unstable yield, due to poor fruitset or fruitlet abscission. The phenomenon is known as ‘shatter’ and this study aims to explore the potential of applying ...
Comparative anatomy and development of pectoral and pelvic girdles in hylid anurans
(Wiley-liss, Div John Wiley & Sons Inc, 2018-07)
The development of the tetrapod pectoral and pelvic girdles is intimately linked to the proximal segments of the fore- and hindlimbs. Most studies on girdles are osteological and provide little information about soft ...
Comments on the morphology of basal paravian shoulder girdle: New data based on unenlagiid Theropods and Paleognath birds
(Frontiers Media, 2021-05)
In 1976 John Ostrom published an enlightening paper about the anatomical transformations in the shoulder girdle and forelimb elements along the origin of birds. Most of his ideas were based on comparing Archaeopteryx ...
Pectoral Girdle Morphology in Early-Diverging Paravians and Living Ratites: Implications for the Origin of Flight
(American Museum of Natural History, 2020-08)
Discussions about the origin of flight almost unanimously assume that early birds positioned (and moved) their wings in the same basic manner as living flying birds, with reconstructed wings extended with the airfoil surface ...
Osteological Atlas of Melanophryniscus (Anura, Bufonidae): a Synthesis after 150 years of Skeletal Studies in the Genus Herpetological Monographs
(Herpetologists League, 2021-06)
Toads of the genus Melanophryniscus are known since the mid-late 19th Century, and the first skeletal description was made early in 1875. However, it was not until the 1970s that osteological variation was discussed in a ...
Hind limb osteology of Gracilisuchus stipanicicorum (Archosauria: Pseudosuchia)
(Royal Society of Edinburgh, 2011-06)
Gracilisuchus stipanicicorum Romer, 1972, from the Middle-Late Triassic of the Ischigualasto-Villa Unión Basin of Argentina, is an extinct pseudosuchian archosaur on the stem toCrocodylomorpha. The pelvic girdle and hind ...
Ontogenetic shape changes in the pelvis of the Greater Rhea (Aves, Palaeognathae) and their relationships with cursorial locomotion: a geometric morphometric approach
(Wiley Blackwell Publishing, Inc, 2020-06)
Knowledge of the ontogenetic pattern of morphological features is essential to improve biological interpretations. The study of morphological features of the pelvic girdle and hind limb apparatus throughout growth is an ...
A new plesiosaur (Reptilia: Sauropterygia) specimen from the upper cretaceous of west antarctica, with comments on the ontogeny and morphological diversity of the elasmosaurid pelvic girdle
(Carnegie Museum of Natural History, 2020-08)
Although knowledge of Mesozoic marine reptiles from Antarctica has improved considerably in recent years, associated and well-preserved skeletal material of these animals remains uncommon. Here we describe a largely complete, ...
Vegetative rescue and in vitro propagation of Persea willdenoviiRescate vegetativo y propagación in vitro de Persea willdenovii

The network ontogeny of the parrot: Altriciality, dynamic skeletal assemblages, and the avian body plan
(Springer Verlag Berlín, 2020-11-23)
We analyze the connectivity patterns and fusion events among bones leading to the adult skeletal organization during the development of the superaltricial monk parakeet (Myiopsitta monachus, Psittaciformes), providing ...
