Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

open access: yesAustral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Biases in Amphibian Sampling in the Amazon: Using Infrastructure and Accessibility Data to Identify Sampling Gaps

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
Biogeographic knowledge of Amazonian amphibians is constrained by spatial and temporal coverage, leading to biases that affect the understanding of their diversity patterns. Using an extensive occurrence database, this study identified knowledge gaps and sampling biases linked to infrastructure and accessibility factors across the region.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

A generalized nonlinear tempeature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson) Função não linear de resposta à temperatura para alguns parâmetros de crescimento e desenvolvimento em kiwi (Actinidia deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson)

open access: yesCiência Rural, 2003
Temperature is a major factor that affects metabolic processes in living organisms. Thermal time has been widely used to account for the effects of temperature on crop growth and development. However, the thermal time approach has been criticized because
