Indicadores bibliométricos para diagnosticar la endogamia editorial en revistas científicas [PDF]
, 2022 La endogamia editorial en revistas científicas es uno de los aspectos determinantes en la evaluación de estas. La poca presencia de endogamia favorece el posicionamiento, la visibilidad y potencialmente su impacto.

Conservation Biology, Volume 37, Issue 6, December 2023., 2023 Abstract Reduction in population size, with its predicted effects on population fitness, is the most alarming anthropogenic impact on endangered species. By introducing compatible individuals, genetic rescue (GR) is a promising but debated approach for reducing the genetic load unmasked by inbreeding and for restoring the fitness of declining ...

Depressão por endogamia em populações de milho de tamanho reduzido
, 2002 Inbreeding is a well known phenomenon in living beings and its immediate consequence is the decrease in the expression of quantitative traits, known as inbreeding depression. Selfing is the most common system of inbreeding in plant species; however, little has been studied with other less severe inbreeding systems, such that resulting from small ...

Genetic diversity and IUCN Red List status
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool for conservation assessment. The IUCN uses information about a species’ range, population size, habitat quality and fragmentation levels, and trends in abundance to assess extinction risk.

Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We

Journal of Ecology, Volume 109, Issue 5, Page 2152-2162, May 2021., 2021 Biogeographic patterns of variation in reproductive success in an invasive weed with allopatric distribution. Abstract Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may lead to ...

Endogamia e seus efeitos na raça Holandesa
Research, Society and Development, 2022 A depressão endogâmica como consequência do acasalamento entre animais aparentados, impulsionada por biotécnicas reprodutivas e métodos de seleção, afeta características de interesse zootécnico, o que causa perdas econômicas e de diversidade genética, além de limitar o progresso genético.
