Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Ibis, EarlyView.Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...

Maternal &Child Nutrition, EarlyView.Only 7% of pregnant women in rural South Angola reached the minimum dietary diversity for women. Food insecurity measured by Food Insecurity Experience Scale and by the Household Dietary Diversity Score was above 70%, but the association with women dietary diversity varied depending on the indicator used. ABSTRACT Dietary diversity in pregnant women is

Automated identification of spotted‐fever tick vectors using convolutional neural networks
Medical and Veterinary Entomology, EarlyView.We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.
