Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

Limnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Decoding Molecular Mechanisms of Pongamia pinnata Phytochemicals in Cancer Therapy

Medicine Advances, EarlyView.
Pongamia pinnata phytochemicals have multiple anticancer mechanisms, including antioxidant, anti‐inflammatory, anti‐metastatic, and apoptosis‐inducing activities through molecular‐level regulation. These bioactive compounds protect normal cells from oxidative stress while promoting reactive oxygen species‐mediated tumor cell death and suppressing ...

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

Bone Adaptation and Labor Organization in Co‐Located Medieval Anatolian Populations

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Skeletal evidence from geographically co‐located populations offers a rare opportunity to disentangle subsistence‐driven bone adaptation from socially organized labor. This study examines upper limb morphology in two Byzantine communities—the urban center of Tyana (10th–13th c.

A future in the past : urban agroforestry systems in future planned urban settlements in Kiribati, a Pacific case study [PDF]

, 2008
In the last 50 years, Pacific Island Countries (PICs) have experienced unprecedented levels of urban development. During this time, the general failure of traditional industrialised planning models to be successfully adapted in PICs has resulted in the ...

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Rethinking Public Administration Reform: Institutional Layering of Bureaucratic, Managerial and Community Logics Over Time in Nigeria's Tax Administration

Public Administration and Development, EarlyView.
ABSTRACT The reform of public institutions has attracted sustained attention in both scholarship and policymaking. Increasingly, however, there is growing recognition that reforms are rarely implemented in an institutional vacuum. Instead, new reforms are layered onto existing arrangements, producing hybrid institutional landscapes shaped by prior ...

Combined storytelling and mapping approaches for increasing community engagement with woodland creation and expansion projects

People and Nature, EarlyView.
Abstract Forests and woodlands are important for biodiversity, climate change mitigation and the provision of services including recreation, timber and non‐timber forest products. Land use policies currently aim to increase forest cover while also maximising the benefits of forests for people and improving community engagement with the process of ...
