GIS and Remote Sensing Phycological Applications
Acquiring GPS coordinates has become self-evident, with handheld GPS devices nowadays fitting within any budget, provided that accuracy requirements are not smaller than 10-15 m. Devices capable of handling publicly available differential correction signals like Wide Area Augmentation System (WAAS, covering North America), European Geostationary Navigation Overlay Service (EGNOS, covering Europe), and equivalent systems in Japan and India are slightly more expensive but offer accuracies between...
Introduction
There are two main players that form the basis of nearly all global ecosystems in converting solar energy to biomass algae and plants. While plants are omnipresent in public discussions dealing with such topics as climate change, bioreactors, biofuels and green biotechnology, the role and potential of algae is usually known only to experts. However, algae are present as primary producers in nearly all types of ecosystems, their versatile physiology allowing them an impressive range of adaption...
Removing Oneself From Damage
Notwithstanding the unequivocal position of the mishnayot surveyed above, prohibiting the existence of hazards, the Halakhic ruling has been set according to the more lenient method of Tanaic (Mishnaic sage) Rabbi Yossi, who established that it is incumbent on the one who suffers the damage to distance himself from it.44 However, this approach was qualified by later-day Talmudic sages, who stated that in clear cases of hazards, as direct as a hit of an arrow, Rabbi Yossi concedes that the onus...
Deep Ecology Ecofeminism Ecophilosophy
Already the early nineteenth-century ecologists - such as Henry David Thoreau, John Muir, and Aldo Leopold - realized that protecting nature entailed much more than fencing in a parcel of land and preventing humans from exploiting its fauna and flora. They quite understood that the then incipient ecological crisis was at its heart a cultural and a moral crisis the result of the cultivation of a modern Western ideal of human existence that saw its fulfillment in the amassing of material...
General Discussion and Conclusion
It is difficult to give a definite answer to the question we asked ('Is global warming involved in the success of seaweed introductions '). Several distortions may affect the data set we used. (i) Study taxa and study areas largely depend upon the phycologists and their location. (ii) Large introduced species, belonging to taxa whose delineation is not controversial, are easier to detect than tiny species whose taxonomy is confused and accessible to very few specialists. (iii) Cryptogenic...

Biomass
The A. nodosum resource has been divided into six geographic areas along the Nova Scotia and southern New Brunswick shores (Fig. 3). Acadian Seaplants Limited (ASL), a Canadian seaweed processing company, has been granted 11 leases in NS in the most productive rockweed areas, and the whole of the southern NB coastline. The area corresponds to 76 of the total resource for the region. For management purposes, the company has divided its leases into 340 harvesting sectors (Ugarte and Sharp, 2001)...
Microalgae as Second Generation Energy Plants
The use of microalgae for the production of biofuels has many ecological and economical advantages. First of all, microalgae show a much higher efficiency in converting solar energy to biomass. From the biomass of corn grown on one hectare, about 2,000 m3 biogas (methane) can be obtained however, biomass of microalgae grown on the equivalent area produces about 200,000 m3 (Solarbiofuels 2008). In microalgal biomass, the percentage of compounds suitable for the production of biofuels (e.g.,...

Biofuels
Biofuels (biogas, bioalcohol, biodiesel) are made from plant biomass, and are more or less carbon neutral, since in burning they do not increase the overall CO2 content of the atmosphere but set free just the amount of CO2 that was fixed before in photosynthesis of the plant (Schiermeier et al., 2008). Thus, in recent years, plant biomass has gained growing importance as an alternative energy source. Main current sources of bioalcohol (mostly bioethanol) are sugars of sugarcane and starch of...

Caulerpa Species as Adsorbents for Pollutants
The high adsorption properties of preparations from Caulerpa species on dyes and heavy metals have recently attracted increasing interest. Caulerpa species are proposed as low-cost adsorbents in these studies. Several physicochemical characterisations such as determination of adsorption kinetics, equilibrium constants and thermodynamics of the adsorption process have been reported. Generally, pseudo-first-order and pseudo-second-order kinetic models are used to express adsorption kinetics....
Effects of Temperature Increases
Temperature is probably the most dominant rate-determining factor in biology ranging from subcellular to community-level processes, with direct and indirect effects on organisms' physiology, ontogeny, trophic interactions, biodiversity, phenology, and biogeography. Increases in temperature due to climate change have the potential to impact most marine ecosystems, directly through the impact on species physiology (growth, reproduction, etc.) or indirectly through impacts on ocean dynamics...
Distribution And Niche Modeling
For centuries, biogeographical patterns have been studied in a descriptive way by delineating provinces and regions based on the presence of observed species and degrees of endemism, rather than quantifying and explaining these patterns based on environmental variables (Adey and Steneck, 2001). The question as to which environmental variables best explain seaweed species' niches and distributions is, however, one of the most important in global change research. Biogeographical models based on...
Other Activities of Caulerpa Preparations
The non-specific agglutination of human red blood cells (haemagglutinating activity) was reported in extracts of Caulerpa cupressoides by Ainouz and Sam-paio (1991). Thangam and Kathiresan (1991a) reported the mosquito larvicidal effect of C. scalpelliformis extracts against Aedes aegypti with an LC50 value of 54 mg L. The same researchers also reported the synergetic effect of C. scalpelliformis extract with the synthetic insecticide 1,2,3,4,5,6-hexachlorocyclohexane (BHC) (Thangam and...
Principles for Removing Modern Nuisances
Following are several applicable principles Serious ecological nuisances will be removed from the town up to a distance from which they will no longer cause harm. Town planning should include the allocation of industrial areas located at a distance from town, to ensure that industrially related activities will not take place within city bounds.30 Cottage industry can 28 Nachmanides (Spain, thirteenth century), in his commentary on Deuteronomy 22 6, acknowledged the possibility that man could...
Ecoactivism Ecology as Religion
Greenpeace is probably the world's best-known association of eco-activists. What is less known is its religious background Robert Hunter, its founder intended his movement to represent ecology as religion, describing its ethics as one of personal responsibility and confrontation. Hunter also believed that whales are the highest developed living beings on earth - higher than humans this is the background to the highly publicized Save the Whales campaigns. The members of Greenpeace also believe...
The Dominant Secondary Metabolite of Caulerpa Genus Caulerpenyne CYN
Caulerpa spp. contain several linear terpenoid secondary metabolites and especially caulerpenyne (CYN, Fig. 1) has been associated with anti-cancer, anti-proliferative, anti-microbial, anti-herpetic and anti-viral properties in many reports. Both invasive Caulerpa spp. contain the dominant sesquiterpenoid metabolite CYN, which can be found in high concentrations up to 1.3 of the dry weight of the alga (Amade and Lem e, 1998 Dumay et al., 2002). CYN contents of invasive and non-invasive Caulerpa...
Discovering Ecological Wisdom in Ancient Texts
Stung by White's and Toynbee's criticism, the monotheists began to reread and reinterpret their scriptures from an ecological perspective. They discovered a great many texts that appear to provide support for contemporary ecological thinking. A recent edition of a popular English Bible translation marks all texts that refer to nature in green - all in all about a thousand. Rabbi Sharon Joseph Levi sees an ecological command in the Talmud text God created Adam and led Adam through the trees in...
