Effects of soil texture, soil depth, and treatment on septic tank effluent renovation [PDF]

, 2009
This study compared the effects of soil texture, soil depth, and additional treatment, by constructed wetland (CW) and recirculating sand filter (RSF) systems, on wastewater renovation in a texture group 2 (loam) and a texture group 3 (clay loam) soil ...

Soil Water Retention: Uni-Modal Models of Pore-Size Distribution Neglect Impacts of Soil Management [PDF]

, 2018
Most models describing soil water retention imply a uni-modal pore-size distribution (PSD). The uni-modal model presented by van Genuchten (termed vanG) is widely used although double-exponential models (termed Dex) implying a bi-modal PSD may better ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Effects of soil texture and planting depth on germination and survival of Nepeta asterotricha [PDF]

علوم و فناوری بذر ایران, 2017
Germination is the first and the most critical stage of plant growth since the early stages of plant growth, such as germination, seedling growth and establishment play in the evolution of plants important role.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Space-time modeling of soil moisture: Stochastic rainfall forcing with heterogeneous vegetation [PDF]

, 2006
The present paper complements that of Isham et al. (2005), who introduced a space-time soil moisture model driven by stochastic space-time rainfall forcing with homogeneous vegetation and in the absence of topographical landscape effects.

Plastic limits of agricultural soils as functions of soil texture and organic matter content [PDF]

, 2012
The plastic limits (lower plastic limit, PL; and liquid limit, LL) are important soil properties that can yield information on soil mechanical behaviour.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Global Optimization of Soil Texture Maps From Satellite‐Observed Soil Moisture Drydowns and Its Implementation in Noah‐MP Land Surface Model

Journal of Advances in Modeling Earth Systems
Soil moisture (SM) plays an important role in regulating regional weather and climate. However, the simulations of SM in current land surface models (LSMs) contain large biases and model spreads. One primary reason contributing to such model biases could

Validation of two SVAT models for different periods during the West African monsoon

Meteorologische Zeitschrift, 2012
In climate and weather forecast models, multi-layer soil-vegetation-atmosphere transfer schemes (SVAT) simulate the soil-atmosphere exchange. Often, these SVAT schemes are used without a profound knowledge of the essential input parameters.
