Mudanças na fecundidade adolescente segundo escolaridade entre 1991 e 2010 no Brasil: os diferenciais se alteram ao longo do tempo?

Revista Latinoamericana de Población, 2019
O Brasil experimentou recentemente declínio da fecundidade adolescente e aumento da cobertura escolar. Neste contexto, os diferenciais da fecundidade na adolescência segundo grupos educacionais podem diminuir ou mesmo aumentar.

USO DE DADOS DO SINASC NA ANÁLISE DO ADIAMENTO DA FECUNDIDADE NO BRASIL

Cadernos de Estudos Sociais
O Brasil vem experimentando o adiamento da fecundidade, caracterizado pelo aumento da idade média em que as mulheres têm filhos. Na Demografia, essas mudanças são definidas como efeito tempo que, tradicionalmente, tem sido mensurado a partir da ...

Associação entre equidade de gênero na família e intenções de fecundidade: uma análise do contexto brasileiro com machine learning [PDF]

Revista Brasileira de Estudos de População
Resumo A literatura sobre equidade de gênero e fecundidade propõe uma curva em U para explicar a relação entre essas variáveis. À medida que as mulheres alcançam maior equidade na esfera pública (educação e trabalho), seus custos de oportunidade aumentam,

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta-analysis in insects. [PDF]

Evol Lett, 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Hidden demographic impacts of fishing and environmental drivers of fecundity in a sea turtle population

Conservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Fisheries bycatch is a critical threat to sea turtle populations worldwide, particularly because turtles are vulnerable to multiple gear types. The Canary Current is an intensely fished region, yet there has been no demographic assessment integrating bycatch and population management information of the globally significant Cabo Verde ...

Precipitation timing and soil substrate drive phenology and fitness of Arabidopsis thaliana in a Mediterranean environment

Functional Ecology, Volume 37, Issue 9, Page 2471-2487, September 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract In Mediterranean climates, the timing of seasonal rains determines germination, flowering phenology and fitness. As climate change alters seasonal precipitation patterns, it is important to ask how these changes will affect the phenology and fitness of plant populations.

The role of cell size in shaping responses to oxygen and temperature in fruit flies

Functional Ecology, Volume 37, Issue 5, Page 1269-1279, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract The body size of an animal is strongly coupled to key ecological traits such as fecundity, mortality and growth. Ectothermic animals mature at smaller body sizes in warmer conditions and under low oxygen availability (hypoxia).

Bridging gaps in demographic analysis with phylogenetic imputation

Conservation Biology, Volume 35, Issue 4, Page 1210-1221, August 2021., 2021
Abstract Phylogenetically informed imputation methods have rarely been applied to estimate missing values in demographic data but may be a powerful tool for reconstructing vital rates of survival, maturation, and fecundity for species of conservation concern.

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna

Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021
Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).
