We examined the effects of female reproductive status (ovigerous and non-ovigerous) on chimney characteristics and time allocation for surface activities in Uca rosea (Tweedie, 1937) (currently referred to as Tubuca rosea (Tweedie, 1937)). We investigated time spent on feeding, standing, in burrow, surface mating, walking, grooming, and digging of 13 ovigerous and 20 non-ovigerous females of similar-size and measured the diameter, width, and height of their chimneys. Chimneys of ovigerous females were wider and higher than those of non-ovigerous females, but chimney diameters did not differ. Ovigerous females spent less time on feeding and walking, but more time on standing, inside burrows, and mating than non-ovigerous females. Feeding rate/min did not differ between ovigerous and non-ovigerous females. This study reports, for the first time, that reproductive status of females affects chimney characteristics and time allocation for surface activities in U. rosea.

Evidence of altered cholesterol and steroid hormones in autism is increasing. However, as boys are more often affected, evidence mainly relates to autistic males, whereas evidence for affected autistic girls is sparse. Therefore, a comprehensive gas chromatography mass spectrometry-based steroid hormone metabolite analysis was conducted from autistic girls. Results show increased levels of several steroid hormones, especially in the class of androgens in autistic girls such as testosterone or androstenediol. The increase of the majority of steroid hormones in autistic girls is probably best explained multifactorially by a higher substrate provision in line with the previously developed cholesterol hypothesis of autism.
