The skeletal integrity of chickens is an important area of research and detailed measures are needed to better understand the influence of experimental manipulation on bone health. The objective of this experiment was to compare 2 methods to measure the superficial tibiotarsus (tibia) morphology of ...

The study aimed to reveal the similarities and differences of the tongue of the merlin with other bird species. Merlin is the smallest bird of the Falconidae family and lives in America, the northern regions of Europe and Asia, the Middle East, and Central Asia. Since these species don't have...

The rumen is a complex organ that is critical for its host to convert low-quality feedstuffs into energy. The conversion of lignocellulosic biomass to volatile fatty acids and other end products is primarily driven by the rumen microbiome and its interaction with the host. Importantly, the rumen is ...

Two new species of apple snails are described, Pomacea penai sp. nov. and Pomacea reevei sp. nov. that are used as food resources in Peruvian Amazonia. We used anatomical and conchological features to diagnose these two species. Pomacea penai sp. nov. is characterized by a highly variable shell...

In this study, it was aimed to determine the shape of the incus in horse and donkey by geometric morphometric method and to evaluate the shape differences between horse's and donkey's incus. The left incus bone of 5 adult horses and 5 donkeys were used in the study. Incus were photographed at same...

Members of Penaeus s.l. are the most economically important shrimps, but there has been substantial confusion on their classification over the last few decades. In this study, we reconstructed a robust molecular phylogeny for these shrimps based on the most extensive dataset to date in terms of the ...

Otological studies rely on a lot of data drawn from animal studies. A lot of pathological or evolutionary questions may find answers in studies on primates, providing insights into the morphological, pathological, and physiological aspects of systematic biological studies. Our study on auditory...

The pelvis, formed by the ilium, ischium and pubis, forms the coxal, which is the largest of the flat bones of the skeleton, with an important role in the physiology of birth. Vastly studied in domestic animals, there is still much to be investigated regarding the anatomical classification in wild...

The goal of this study was to establish some topographical and morphological peculiarities of the thyroid glands in chickens, turkeys, and ducks. On this basis, we offer practically easy access to reveal and sampling the thyroids in each of the three species of birds. Thyroid glands of 12 broiler...
