Abstract: The male genitalia of pholcid spiders, which is one of the most species-rich spider families, are characterized by a procursus, which is a morphologically diverse projection of the copulatory organ. It has been shown that… read more here.

DOI: 10.1111/jne.13127
Abstract: In male Japanese quail, brain aromatase is crucial for the hormonal activation of sexual behaviour, but the sites producing neuro‐oestrogens that are critical for these behaviours have not been completely identified. This study examined the… read more here.

DOI: 10.1371/journal.pone.0217175
Abstract: We examined copulatory behaviour in the Bonelli´s Eagle (Aquila fasciata) at nesting sites in the eastern zone of the Baetic Cordillera, southern Spain, between 2010 and 2012. We observed the copulatory behaviour of 15 pairs… read more here.
