Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Effects of Geopotential and Atmospheric Drag Effects on Frozen Orbits Using Nonsingular Variables [PDF]

, 2014
The concept of frozen orbit has been applied in space missions mainly for orbital tracking and control purposes. This type of orbit is important for orbit design because it is characterized by keeping the argument of perigee and eccentricity constant on ...

Prenatal Environmental Hypoxia Enhances Adult Hypoxia Tolerance in Brandt's Voles (Lasiopodomys brandtii): Behavioral and Transcriptomic Insights

Integrative Zoology, EarlyView.
Prenatal hypoxia enhances adult hypoxia tolerance in Brandt's voles, preserving cognitive and memory functions. Transcriptomic analysis reveals adaptive changes in energy metabolism, oxygen transport, and neuroprotective mechanisms, highlighting developmental plasticity.

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

Journal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

Journal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Atributos químicos do solo em plantios florestais em substituição à vegetação nativa em campos de altitude

Ciência Florestal, 2020
Os plantios de espécies florestais exóticas vêm aumentando em áreas cobertas por vegetação nativa na região nordeste do Rio Grande do Sul, o que pode alterar as dinâmicas dos nutrientes no solo. Dessa maneira, o objetivo deste estudo foi avaliar os efeitos da mudança de uso da terra sobre pH e teores de carbono orgânico total (COT), Al3+, Ca2+, Mg2+ e ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...
