Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela)

Journal of Morphology, Volume 287, Issue 3, March 2026.
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...

Soil carbon, nitrogen, and biological activity as affected by land use and grassland management across North Carolina

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Undisturbed land uses have the potential to enhance soil organic matter, but how and to what extent this occurs on private farms remains relatively unexplored. A cross‐sectional study of perennial grasslands and farm woodlots was undertaken across North Carolina to investigate stocks of soil organic C, total soil N, and soil‐test biological ...

On the difference between exclosures and enclosures in ecology and the environment [PDF]

, 2008
Rehabilitation of degraded land in arid and semiarid environments often involves excluding livestock from degraded sites, creating what are usually but unfortunately not consistently, called _exclosures_.

Defining soil: Proposals of zero‐states, active layer, and págousols (from ice parent materials) to fundamentally expand soil science

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...

3D representation of soil distribution: An approach for understanding pedogenesis Représentation 3D des sols, apports à la compréhension de la pédogenèse [PDF]

, 2009
International audienceSoils are characterised by a spatial variability in the three dimensions (3D) of space. However, 3D studies remain scarce due to the qualitative nature of many soil horizon characteristics, notably the horizon designation.

Microtopography controls organic and inorganic carbon stocks in Vertisols: Insights from a climosequence on the Texas coastal plain

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Complex interactions between ecological and environmental factors govern soil organic carbon (SOC) and soil inorganic carbon (SIC) stocks across landscapes. In gilgai‐bearing Vertisols, submeter differences in water availability result in micro‐spatial variability in soil properties.

Genesis of Soils from Bauxite in Southeastern Brazil: Resilication as a Soil-Forming Process

Revista Brasileira de Ciência do Solo, 2017
Pedological studies using X-ray diffraction (XRD), X-ray fluorescence (XRF), optical microscopy, and scanning electron microscopy (SEM-EDS) showed a Xanthic Ferralsol formed from the degradation of bauxite on a slope in the Caparaó region, in ...
