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

open access: yes
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

The shape of ecological networks

open access: yes, 2001
We study the statistics of ecosystems with a variable number of co-evolving species. The species interact in two ways: by prey-predator relationships and by direct competition with similar kinds.

Efficient Selective Adsorption of Anionic Dyes by Modified Activated Alumina Spheres

open access: yesAsia-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.

Fishing Without a Trace? Assessing the Balanced Harvest Approach Using EcoTroph

open access: yesFrontiers in Marine Science, 2020
Distributing fishing mortality across the widest possible range of species, stocks, and sizes in proportion to their natural productivity (i.e., balanced harvest, BH) has been suggested as a new paradigm of fisheries management to minimize the effects of

Throughflow centrality is a global indicator of the functional importance of species in ecosystems

open access: yes, 2012
To better understand and manage complex systems like ecosystems it is critical to know the relative contribution of system components to system functioning. Ecologists and social scientists have described many ways that individuals can be important; This

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...

Establishing isotopic turnover rates and trophic discrimination factors in tiger beetle (Coleoptera: Cicindelidae) larvae through a diet switch experiment [PDF]

open access: yesPeerJ
Stable isotope ratios give insight into food web interactions, but interpretation can be clouded by the timing of isotopic change associated with changes in diet and the difference in isotope ratios between consumers and their diets at equilibrium.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Trophic factors as modulators of motor neuron physiology and survival: implications for ALS therapy

open access: yesFrontiers in Cellular Neuroscience, 2014
Motor neuron physiology and development depend on a continuous and tightly regulated trophic support from a variety of cellular sources. Trophic factors guide the generation and positioning of motor neurons during every stage of the developmental process.

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

open access: yes
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 ...
