Injectable Chondroitin Sulfate Methacrylate Hydrogel Microspheres Co‐Loaded with GLPM Nanozyme, Dexamethasone, and Stem Cells for Synergistic Osteoarthritis Therapy

Advanced Science, EarlyView.
A multifunctional injectable microsphere system is fabricated via UV‐assisted microfluidic cross‐linking, integrating nanozyme‐based ROS scavenging, sustained dexamethasone release, and stem cell delivery. Upon IA injection, the microspheres adapt to joint stress, suppress inflammation, and promote cartilage regeneration, offering a minimally invasive ...

Emergent competition shapes top-down versus bottom-up control in multi-trophic ecosystems.

PLoS Computational Biology
Ecosystems are commonly organized into trophic levels-organisms that occupy the same level in a food chain (e.g., plants, herbivores, carnivores). A fundamental question in theoretical ecology is how the interplay between trophic structure, diversity ...

Trophic interactions in a changing world: modelling aboveground–belowground interactions

Basic and Applied Ecology, 2004
The rate and scale of human-driven changes can exert profound impacts on ecosystems, the species that make them up and the services they provide that sustain humanity. Given the speed at which these changes are occurring, one of society's major challenges is to coexist within ecosystems and to manage ecosystem services in a sustainable way.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

TROPHIC CIRCULATION IN ECOSYSTEMS

Ecosistemas y Recursos Agropecuarios, 2016
The trophic aspect of ecology has been studied for more than six decades; in this contribution we address theoretical aspects relative to the concept of trophic ow at the ecosystem level and from the thermodynamics point of view.

Trophic model of the coastal fisheries ecosystem of the southwest coast of India [PDF]

The Ecopath approach and software were used to construct a trophic model of the coastal fisheries ecosystem of the southwest (SW) coast of India. The model consisted of 11 ecological groups and used estimated landings from all areas along the southwest ...

Unified "micro"- and "macro-" evolution of eco-systems: Self-organization of a dynamic network

, 2003
Very recently we have developed a dynamic network model for eco-systems that achieved ``unification'' of ``micro'' and ``macro''-evolution. We now propose an extension of our model so as to stabilize the eco-system and describe {\it speciation} in a more

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

American Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Efficient Selective Adsorption of Anionic Dyes by Modified Activated Alumina Spheres

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The persistent environmental threat from dye‐contaminated industrial wastewater necessitates advanced remediation solutions. Hydrochloric acid–modified activated alumina spheres (HAAs) are presented as efficient adsorbents for anionic dye removal.

Trophic model of the coastal fisheries ecosystem of the west coast of peninsular Malaysia [PDF]

A preliminary mass-balance trophic model was constructed for the coastal fisheries ecosystem of the West Coast of Peninsular Malaysia (0 - 120 m depth). The ecosystem was partitioned into 15 trophic groups, and biomasses for selected groups were obtained
