During surveys in central Florida of the zombie-ant fungus Ophiocordyceps camponoti-floridani , which manipulates behavior carpenter ant Camponotus floridanus two distinct fungal morphotypes were discovered associated with and purportedly parasitic on O. . Based a combination unique morphology, ecology phylogenetic placement, we that these comprise novel lineages fungi. Here, propose new genera...

A skeleton amplifies the minute contractions of muscles to animate the body of an animal. The degree that a muscular contraction displaces an appendage is determined by the gearing provided by the joints of a skeleton. Species that move rapidly commonly possess joints with relatively high gears that produce a large output displacement. However, the speed of an appendage can depend on dynamics t...

background continuous epidural analgesia with catheterization is a useful technique, because it has a wide adaptation range and provides prolonged analgesia. problems that may arise from long-term epidural analgesia are changes in the analgesic area, duration of analgesia and catheter-related problems. few articles have evaluated gradual changes of long-term epidural analgesia. in the animal mo...

Background: There are some methods for morphology staining of sperm. Although many different and also new methods are used in semen analysis, light microscopy is still used for routine morphological evaluation. The most used of the methods is Papanicolaou staining. This method is routinely used in Andrology laboratory for Human sperm morphology staining. In some domestic animals such as bull, R...

The morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (Felis catus). The eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. Results showed that the general structure of photoreceptor layer in this...

Lens regeneration in adult mice is possible when the lens capsule is left behind after lentectomy. The lens is regenerated by the remaining adherent lens epithelial cells, which differentiate to form lens fibres within days, showing normal morphology and bow regions. Epithelial to mesenchymal cell transformation is also seen during the early stages. The mouse, therefore, can become an indispens...

There has been an increasing interest in studying animal behaviours [1]. In the EU funded project “ChiRoPing: Developing Versatile and Robust perception using Sonar Systems that Integrate Active Sensing, Morphology and Behaviour” [2], the interest is placed on Chiroptera (bats) as bats are the nature’s expert in active sonar sensing [3]. Study of bats’ behaviour is not only of biological intere...
