Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions. [PDF]

J Anim Breed Genet
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Genomic Prediction and Genome-Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model. [PDF]

J Anim Breed Genet
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Genetic Evaluation of Barrel Racing Performance in Quarter Horses. [PDF]

J Anim Breed Genet
ABSTRACT Barrel racing is a competitive timed rodeo event that challenges horses and riders to complete a cloverleaf pattern around three barrels in the fastest time possible. In this study, we aimed to estimate the genetic parameters of barrel racing time (BRT) and evaluate the most suitable statistical model for its analysis.

Gene Co-Expression Networks Highlight Key Nodes Associated With Ammonium Nitrate in Sugarcane. [PDF]

Physiol Plant
ABSTRACT This study aimed to investigate molecular mechanisms underlying nitrogen use efficiency (NUE) in sugarcane by analyzing transcriptome profiles of two genotypes (responsive, RB975375; non‐responsive, RB937570) under contrasting nitrogen conditions, and along the leaf development gradient.

Melhoramento da soja: II. Melhoramento por hibridação [PDF]

Bragantia, 1958
Três séries de cruzamentos artificiais de soja entre as variedades Abura X Mogiana, La 41-1219 X D 49-772 e La 41-1219 X Mogiana, são relatadas. As populações descendentes destes híbridos foram estudadas, parte pelo método de seleção individual e parte pelo método de "mistura" (bulked), durante cinco gerações. Pela seleção individual tornou-se possível

Melhoramento do cafeeiro: V - Melhoramento por hibridação [PDF]

Bragantia, 1952
A hibridação como método de melhoramento do cafeeiro, oferece amplas possibilidades que ainda se acham pouco exploradas. Para o caso da espécie C. arabica, a hibridação entre suas variedades, além de fornecer dados seguros sôbre a constituição genética, permite também a verificação de ocorrência da heterose, o melhoramento sem mudança dos caracteres ...

Women of the revolution and a politics of care: A gendered intersectional approach on an initiative to address socioenvironmental problems in a marginalized community in southern Brazil

Gender, Work &Organization, Volume 30, Issue 6, Page 2130-2154, November 2023., 2023
Abstract The Buckets Revolution is a local non‐governmental organization arisen from an initiative implemented in a favela, a marginalized community in the South of Brazil, led and conducted by its women to resist their condition of intersected subordinations and address the socioenvironmental problems caused by the lack of public care.

MIGRANT URBANISM: Cape Verdean Djunta‐mon and its Impact on the Built Environment of Cova da Moura (Lisbon)

International Journal of Urban and Regional Research, Volume 47, Issue 3, Page 329-348, May 2023., 2023
Abstract International migrations are transforming the urban landscape in cities all around the world. In this article I address the effect of Cape Verdean migration on the built environment of Lisbon's periphery. Specifically, I analyse a traditional practice of mutual aid originating in rural Cape Verde, the djunta‐mon system, as a device of migrant ...

Comparing otolith shape descriptors for population structure inferences in a small pelagic fish, the European sardine Sardina pilchardus (Walbaum, 1792)

Journal of Fish Biology, Volume 102, Issue 5, Page 1219-1236, May 2023., 2023
Abstract Otolith shape analysis has been one of the most used approaches to study population structure in the past decades. Currently, two sets of shape descriptors are used to perform otolith shape analysis, namely, Elliptic Fourier descriptor (EFd), which focuses on the overall otolith shape differences, and Discrete Wavelet descriptor (DWd), which ...
