Morphological Changes in Skin Glands During Development in Rhinella Arenarum (Anura: Bufonidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2016-01)
Avoiding predation is critical to survival of animals; chemical defenses represent a common strategy among amphibians. In this study, we examined histologically the morphology of skin glands and types of secretions related ...
Developmental morphology of granular skin glands in pre-metamorphic egg-eating poison frogs
(2017)
Parents in many taxa, including insects, mol- luscs, fish, snakes, and amphibians provision chemical defences, such as peptides, steroids, or alkaloids to their offspring to reduce the risk of predation. In most cases, ...
The Amazonian toad Rhaebo guttatus is able to voluntarily squirt poison from the paratoid macroglands

Post-metamorphic development of skin glands in a true toad: Parotoids versus dorsal skin
(Wiley-liss, Div John Wiley & Sons Inc, 2017-05)
Chemical defenses in amphibians are a common antipredatory and antimicrobial strategy related to the presence of dermal glands that synthesize and store toxic or unpalatable substances. Glands are either distributed ...
Odorous secretions in anurans: morphological and functional assessment of serous glands as a source of volatile compounds in the skin of the treefrog Hypsiboas pulchellus (Amphibia: Anura: Hylidae)
(Wiley Blackwell Publishing, Inc, 2016-03)
Serous (granular or venom) glands occur in the skin of almost all species of adult amphibians, and are thought to be the source of a great diversity of chemical compounds. Despite recent advances in their chemistry, odorous ...
A Comparative Study of the Biological Activity of Skin and Granular Gland Secretions of Leptodactylus latrans and Hypsiboas pulchellus from Argentina
(ACG Publications, 2014-03)
The potential of the skin of anuran amphibians as a new source of bioactive peptides was investigated . For this purpose, the study collected data in the mid-eastern region of Argentina. Two anuran amphibian species were ...
Comparative study of the ultrastructure and secretory dynamic of hypopharyngeal glands in queens, workers and males of Sceptotrigona postica latreille (Hymenoptera, Apinae, Meliponini)
(Inst Histol Embriol-conicet, 2000-04-01)
The secretory cycle of hypopharyngeal glands (HPGs) in Scaptotrigona postica resembles that of Apis mellifera: in newly emerged workers the HPGs are in prefunctional state, their maximum development happens in the nurse ...
Comparative study of the ultrastructure and secretory dynamic of hypopharyngeal glands in queens, workers and males of Scaptotrigona postica latreille (Hymenoptera, Apinae, Meliponini)
(2000-06-27)
The secretory cycle of hypopharyngeal glands (HPGs) in Scaptotrigona postica resembles that of Apis mellifera: in newly emerged workers the HPGs are in prefunctional state, their maximum development happens in the nurse ...
Glycogen-rich clear cell carcinoma of the feline mammary gland: Case report
(2016-01-01)
The aim of this report is to describe the first histopathological, immunohistochemical, and clinical characteristics of a feline glycogen-rich clear cell carcinoma (GRCCC). A Persian queen was admitted with mammary gland ...
