Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, EarlyView.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Among- and within-population variation in sperm quality in the simultaneously hermaphroditic land snail Arianta arbustorum [PDF]
, 2018 Sperm competition models on the evolution of sperm size assume associations with another sperm quality trait, sperm longevity. Sperm length can also provide an indication of possible mechanisms affecting motility and thus fertilization success.

The ductal network in the human testis and epididymis: What belongs to which?
Clinical Anatomy, EarlyView.Abstract The testes and epididymis are traversed by a system of tubules in which sperm cells are generated, matured, nourished, and transported. Among these are the efferent ductules, which connect the rete testis to the duct of the epididymis. In the Terminologia Anatomica (TA), the efferent ductules are assigned to the testicles, while numerous ...
