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 ...

Using poststratification to improve abundance estimates from multispecies surveys: a study of juvenile flatfishes [PDF]

open access: yes, 2005
Population assessments seldom incorporate habitat information or use previously observed distributions of fish density. Because habitat affects the spatial distribution of fish density and overall abundance, the use of habitat information and previous ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Object identification and characterization with hyperspectral imagery to identify structure and function of Natura 2000 habitats [PDF]

open access: yes, 2010
Habitat monitoring of designated areas under the EU Habitats Directive requires every 6 years information on area, range, structure and function for the protected (Annex I) habitat types.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Method and apparatus for bio-regenerative life support system [PDF]

open access: yes, 1991
A life support system is disclosed for human habitation (cabin) which has a bioregenerative capability through the use of a plant habitat (greenhouse) whereby oxygen-rich air from the greenhouse is processed and used in the cabin and carbon dioxide-rich ...

Semi‐automated assessment for NatureServe subnational conservation status ranks for state floras

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Conservation status ranks measure the potential risk of extinction for species at global, national, and subnational levels, taking into account rarity, threats, and trends. These assessments are largely incomplete due to funding and resource limitations.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Living on the edge: forest edge effects on microclimate and terrestrial mammal activity in disturbed lowland forest in Sumatra, Indonesia

open access: yesOryx
Species–environment relationships are often studied at large spatial scales, but effective conservation requires an understanding of local-scale environmental drivers and pressures.

Regional variation of habitat tolerance by some European spiders (Araneae) - a review [PDF]

open access: yes, 2009
The data presented by HÄNGGI et al. (1995) and BOLAÑOS (2003) on the habitats of a large number of European spiders are examined, most of which appear to show non-specific preferences.
