Nucellar beak structure and pollen tube growth in Cucurbitaceae
(Elsevier Gmbh, 2014-05)
The nucellar beak is a proboscis-like outgrowth of the nucellus at the micropylar end, being the obliged path for the pollen tube entering the ovule. Among the few angiosperm families with nucellar beak, Cucurbitaceae is ...
Distribution of short and long-beaked common dolphin morphs (Delphinus spp.) based on skull's rostrum index analysis along the peruvian and chilean coast
(Sociedad Argentina para el Estudio de los Mamiferos, 2023)
The distribution of the long-beaked and short-beaked common dolphin morphs in the eastern South Pacific is not well defined. The objective of this study was to propose a potential distribution of the two forms along the ...
Beak-trimming methods and their effect on the performance of japanese quail pullets (Coturnix japonica)
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2006-12-01)
This study aimed at verifying if beak-trimming methods in Japanese quail pullets could optimize production by decreasing stress caused by cannibalism. A total number of 816 day-old Japanese quails was distributed in a ...

Beak Trimming by Infrared Radiation of Layers
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2019-01-01)
This study aimed at evaluating beak-trimming methods and intensities on the performance, beak length and uniformity, and egg parameters of commercial layers. During the rearing period, birds were distributed in randomized ...
Beak trimming methods and their effect on the performance and egg quality of Japanese quails (Coturnix japonica) during lay
(Facta-fundacio Arnco Ciência Tecnologia Avicolas, 2007-03-01)
A total number of 720 Japanese quail females, reared under identical management conditions, and receiving feed and water ad libitum, was used. Quails were housed and reared from 1-35 days of age in litter pens in a rearing ...
