Data from: Molecular study of the Amazonian Macabea cattle history

Julio Vargas, Vincenzo Landi, Amparo Martinez, Mayra Mercedez Gomez, María Esperanza Camacho, Luz Ángela Álvarez, Lenin Aguirre, Juan Vicente Delgado & Mayra Gómez
Macabea cattle are the only Bos taurus breed that have adapted to the wet tropical conditions of the Amazon. This breed has integrated into the culture of the indigenous Shuar-Asuar nations probably since its origins, being one of the few European zoogenetic resources assimilated by the deep-jungle Amazon communities. Despite its potential for local endogenous sustainable development, this breed is currently endangered. The present study used molecular genetics tools to investigate the within- and between-breeds...

Data from: Maternal allocation in eggs when counting on helpers in a cooperatively breeding bird

Juliana Valencia, Concha Mateos, Carlos De La Cruz & Juan Carranza
For cooperatively breeding birds, it has been proposed that breeders should reduce their investment in eggs when they count on helpers, because this can be compensated for by helpers provisioning of nestlings. Data from some species have supported this prediction, but this is not the case in others. It has also been proposed that mothers should not reduce but rather increase investment if the presence of helpers enhances the reproductive value of offspring, a pattern...

Data from: Conservation priorities of Iberoamerican pig breeds and their ancestors based on microsatellite information

Oscar Cortés, A. M. Martinez, J. Cañon, N. Sevane, L. T. Gama, C. Ginja, V. Landi, P. Zaragoza, N. Carolino, A. Vicente, P. Sponenberg & J. V. Delgado
Criollo pig breeds are descendants from pigs brought to the American continent starting with Columbus second trip in 1493. Pigs currently play a key role in social economy and community cultural identity in Latin America. The aim of this study was to establish conservation priorities among a comprehensive group of Criollo pig breeds based on a set of 24 microsatellite markers and using different criteria. Spain and Portugal pig breeds, wild boar populations of different...

Fitness can be profoundly influenced by the age at first reproduction (AFR), but to date the AFR-fitness relationship only has been investigated intraspecifically. Here we investigated the relationship between AFR and average lifetime reproductive success (LRS) across 34 bird species. We assessed differences in the deviation of the Optimal AFR (i.e., the species-specific AFR associated with the highest LRS) from the age at sexual maturity, considering potential effects of life-history as well as social and...
