Flower production decreases with warmer and more humid atmospheric conditions in a western Amazonian forest.

Climate models predict that everwet western Amazonian forests will face warmer and wetter atmospheric conditions, and increased cloud cover. It remains unclear how these changes will impact plant reproductive performance, such as flowering, which plays a central role in sustaining food webs and forest regeneration. Warmer and wetter nights may cause reduced flower production, via increased dark respiration rates or alteration in the reliability of flowering cue-based processes.

Seasonality of reproduction in an ever-wet lowland tropical forest in Amazonian Ecuador.

Flowering and fruiting phenology have been infrequently studied in the ever-wet hyperdiverse lowland forests of northwestern equatorial Amazonía. These Neotropical forests are typically called aseasonal with reference to climate because they are ever-wet, and it is often assumed they are also aseasonal with respect to phenology. The physiological limits to plant reproduction imposed by water and light availability are difficult to disentangle in seasonal forests because these variables are often temporally correlated, and both are rarely studied together, challenging our understanding of their relative importance as drivers of reproduction.

Overweight and obesity significantly reduce pregnancy, implantation, and live birth rates in women undergoing In Vitro Fertilization procedures.

Objective: The objective of this study was to evaluate the effects of overweight and obesity on fertility outcomes in IVF procedures.

Methods: This was a retrospective and nonrandomized study that included 191 IVF/ICSI cycles using non-donor oocytes performed between July 2016 and December 2018 that were allocated according to Body Mass Index (BMI) in three groups: Normal group: 18.5-24.

Meta-analysis and Scientific Mapping of Well-being and Job Performance.

In this article, we present a meta-analysis and a scientific mapping about the relationship between different types of well-being and job performance. We followed The PRISMA statement for reporting systematic reviews and meta-analyses (Moher et al., 2009), and conduct the search in Web of Science, SCOPUS, Ebscohost, Proquest, and Jstor databases.

Percentage of Blastulation on the Number and Function of Metaphase II Oocytes.

Objective: Establish the number of metaphase II oocytes that are needed for optimum blastulation rate and to achieve a better rate of gestation.

Methods: Retrospective study. Women diagnosed with infertility.

Low diversity and high host preference of ectomycorrhizal fungi in western Amazonia, a neotropical biodiversity hotspot.

Information about the diversity of tropical microbes, including fungi is relatively scarce. This study addresses the diversity, spatial distribution and host preference of ectomycorrhizal fungi (EcMF) in a neotropical rainforest site in North East Ecuador. DNA sequence analysis of both symbionts revealed relatively low richness of EcMF as compared with the richness of temperate regions that contrasts with high plant (including host) diversity.
