Variation in symbiotic effectiveness in subterranean clover (Trifolium subterraneum L.)

open access: yes, 1961
(1) The symbiotic effectiveness of 15 varieties and of four tetraploid lines of subterranean clover were examined in association with several strains of nodule bacteria.(2) Relatively- small but significant differences in yield occurred between host ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

On the conservation of subterranean ecosystems

open access: yes, 2022
Subterranean ecosystems harbor a broad diversity of specialized organisms that are of interest from both a conservation and evolutionary perspective. These species are often short-range endemics, and some represent ancient faunas that disappeared from ...

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Dietary-driven variation effects on the symbiotic flagellate protists communities of the subterranean termite Reticulitermes grassei Clément

open access: yes, 2017
The ability of subterranean termites to digest lignocellulose relies not only on their digestive tract physiology, but also on the symbiotic relationships established with flagellate protists and bacteria.

The Story of the Architectural Documentation of Hagia Sophia’s Hypogeum

open access: yesOpen Archaeology, 2023
Hagia Sophia’s hypogeum is a group of subterranean Roman tomb structures located in the area between the northeastern side of the structure and the imaret (“soup kitchen”) of Hagia Sophia. Consisting of three chambers connected by a passage, the hypogeum

Digestive Tract Morphology and Gut Microbiota Jointly Determine an Efficient Digestive Strategy in Subterranean Rodents: Plateau Zokor

open access: yesAnimals, 2022
Rodents’ lifestyles vary in different environments, and to adapt to various lifestyles specific digestion strategies have been developed. Among these strategies, the morphology of the digestive tracts and the gut microbiota are considered to play the ...
