(Elsevier, 2012-04)Abaxial tail implantation is a defect occurring in the neck region of spermatozoa and is characterized by misalignment of the centriolar complex relative to the head base. This defect has been described in a number of ...
-
(Springer, 2022-12)Broiler chicken meat is a good source of protein consumed universally, and is one of the most commonly farmed species in world. In addition to providing food, poultry non-edible byproducts also have value. A major advantage ...
-
(Elsevier, 2018-01)In many mammal species, androgen levels in males are elevated during periods of mating activity, often to facilitate aggressive behavior between males over access to fertile females. However, this pattern might be less ...
-
(Elsevier, 2020-12)It has been established that excess germ cells in normal and in pathological conditions are removed from testicular tissue by the mechanism of apoptosis. Studies on germ cell apoptosis in avian species are grossly lacking, ...
-
(Oxford University Press, 2018-10)Male reproductive strategies have been well studied in primate species where the ability of males to monopolize reproductive access is high. Less is known about species where males cannot monopolize mating access. Vervet ...
-
(Elsevier, 2015-01)It is now widely recognized that mating systems contain both social and genetic components, where social components describe patterns of social associations while genetic components reflect patterns of mating activities. ...

(Wiley, 2020-03)Please read abstract in the article.
-
(Wiley, 2017-09)A specialized region of the bill tip characterized by a complex arrangement of mechanoreceptors and referred to as a bill tip organ, has been identified in numerous avians. A bill tip organ was initially inferred in kiwi ...
-
(Elsevier, 2009-08)The pathology of maldronksiekte, a sporadic neurological disorder of cattle caused by the ingestion of the plant Solanum kwebense in certain parts of South Africa, was studied in three chronic field cases. There was loss ...
-
(Springer, 2019-05)Colonies of naked mole-rats (Heterocephalus glaber, NMRs) are characterised by an extreme skew in lifetime reproductive success with only one female and one to three male consorts in a colony. The rest of the individuals ...
-
(Elsevier, 2017-12)The inflammatory burden of the complex rheumatoid arthritis (RA) disease affects several organ-systems, including rheological properties of blood and its formed elements. Red blood cells (RBCs) are constantly exposed to ...
-
(Wiley, 2014-07)Herbst corpuscles are widely distributed throughout the oropharynx of the ostrich and emu in contrast to the general situation in birds. Knowledge of the comparative distribution of Herbst corpuscles in the oropharynx of ...
-
(Wiley, 2018-10)This study describes ciliated, nonciliated and mitochondrial luminal epithelial cells of the isthmus in laying and moulting domestic fowls using histological and ultrastructural techniques. The ciliated cells were nonsecretory, ...
-
A comparative overview of the sperm centriolar complex in mammals and birds : variations on a theme (Elsevier, 2016-06)This paper presents an overview of the structure, function and anomalies of the sperm centriolar complex (CC) on a comparative basis between mammals and birds. The information is based on selected references from the ...
-
(Sage, 2015-01)The pathology in mice infected with neurovirulent South African lineage 2 West Nile virus (WNV) strains has not previously been described. Three- to 4-month-old male BALBc mice were infected with South African neurovirulent ...
-
(Elsevier, 2012-02)The fate of the proximal centriole in passeridan birds is an area of controversy and relative lack of knowledge in avian spermatogenesis and spermatology. This study examines, for the first time, spatiotemporal changes ...
-
(Springer, 2015-09)This study, facilitated by the use of immunohistochemistry, indicated the presence of taste buds in Dromaius novaehollandiae but not in Struthio camelus. Seen at the light microscope level, the taste buds consisted of ...
-
(2012-02)The cellular composition of the testicular capsule, seminiferous peritubular tissue, the epithelia as well as periductal muscle cell layers of the excurrent ducts was studied, in sexually mature and active Masked Weaver ...
-
(Wiley, 2018-12)Reports of the vaginal flora of wild cats such as lions or leopards are scarce. The micro‐organisms most commonly found in the vagina of clinically healthy cats are aerobic bacteria such as coagulase‐negative Staphylococcus, ...
-
(Royal Society, 2019-02)The phenotype of parents can have long-lasting effects on the development of offspring as well as on their behaviour, physiology and morphology as adults. In some cases, these changes may increase offspring fitness but, ...
