It is a simplified but powerful tool to investigate AMF root colonization and development of the extraradical mycelium. The aim of this study was to establish and characterize the in vitro culture of a Cuban strain of Rhizophagus irregularis (INCAM 11) by using transformed chicory roots. For that, superficially disinfected propagules of R. irregularis were co-culture with the hairy transformed chicory roots on Modified Strullu and Romand (MSR) medium during five months. Spore germination was observed 3-5 days after surface disinfection. The first contact between AMF hyphae and roots occurred 1-3 days after germination and a significant production of extensive extraradical mycelium was observed. New spore formation started within 21-25 days. After 5 months, 2000 spores could be observed per plate which were able to germinate, colonize, establish and reproduce again spores when associated to young transformed roots of chicory. The most frequent associated microorganism to the in vitro culture of INCAM 11 was isolated and identified as Paenibacillus sp.","PeriodicalId":140386,"journal":{"name":"Environmental Sciences and Ecology: Current Research (ESECR","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124459685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Uncontrolled urbanisation is a factor in destroying natural resources, which results in severe pollution, particularly in developing countries. The 2030 Agenda for Sustainable Development was launched in 2015 to establish sustainable cities and communities in response to the deteriorating situation. Education is an excellent method of boosting public awareness and knowledge about sustainability. As new urban tourism, campus tourism has grown in popularity over the previous two decades. Campus tourism should address this ongoing environmental issue by utilizing the institution as a knowledge-transfer platform for society. This article studies the available literature to understand the global phenomenon of campus tourism. Six components of campus tourism were identified through a review of the academic literature. Subsequently, this article emphasized the importance of contrasting Edutourism and campus tourism to dispel misconceptions.

Methods: Uncovered deep well slides were filled with culture media containing the large forms of Stentor coeruleus. On evaporation of the culture medium, the cell membrane of these larger forms disrupted. When rehydrated 24 hours later the micronuclei previously released from the dying cells showed the formation of numerous, mobile dwarf cells. Chlorinated tap water added to the medium was used to induce cell death. Results: The initial indication of the dying dwarf cell is “blebbing,” a signature of programmed cell death known as apoptosis. Within 8-12min, the stationary dwarf cell progressively released a morphological replicate of the dead cell before the replicate faded into the ambient environment. In other experiments, just prior to fading, the slide was exposed to a magnetic field (75 milligaus) which caused a retraction of the replicate back into the dwarf cell. Subsequently, the cells resumed their previously mobile activity. Conclusions: These findings support the hypothesis that a phenomenon analogous to the characteristics ascribed to the soul in the metaphysical literature can be demonstrated in the laboratory. We suggest that the responses shown by this unicellular organism at the life/death interphase may be conserved across the evolutionary spectrum.","PeriodicalId":140386,"journal":{"name":"Environmental Sciences and Ecology: Current Research (ESECR","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115816940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Serpentinite Diapirs and the Evolution of Oceanic Core Complexes","authors":"Y. Mart","doi":"10.54026/esecr/1054","DOIUrl":"https://doi.org/10.54026/esecr/1054","url":null,"abstract":"Serpentinites and peridotites are the predominant lithological components of Oceanic Core Complexes (OCCs), located commonly at triple junctions of slow-spreading oceanic accreting ridges, fracture zones and transform faults. These lithologies differ from the surrounding oceanic brittle lithosphere, built of basalt and gabbro, and the structural evolution of these OCCs is enigmatic. The present investigation suggests that the tectonics of OCCs is derived from the ascent of serpentinic diapirs generated by the unique proximity of shallow asthenosphere, faulted lithosphere and the juxtaposition of oceanic crusts of contrasting densities. Such setting initiated two structural stages in the evolution of the OCC, the first is spontaneous subduction of old and dense oceanic crust under the fresh and lighter basalt at the edge of the MOR across its intersection with transform fault - fracture zone. The sub ducted slab would be affected by the combined effect of the steep thermal gradient and the availability of volatiles there to enhance the alteration of pyroxene into serpentine. Analog and numeric experiments show that spontaneous subduction can initiate spontaneously if the density contrast between the juxtaposed slabs is significant, as is the case between fresh basalt (ρ~2.7 g/cm3 ) and older basalt (ρ~2.9 g/cm3 ). Since the average thermal gradient under the MOR is ca. 130o /km, then at depth of 4-5 km the pyroxene and plagioclase would start their alteration, mostly to serpentine. The abundant faults of MOR normal rifting and strike-slip transform faulting could enable the light and malleable serpentinite to form diapirs, which would ascent to the seafloor at the rift-fracture zone intersections. The friction at the top of the diapirs during their ascent would probably generate breccia at their tops. Highlights a) OCCs are built mostly of serpentinite diapirs that carry peridotite inclusions. b) Serpentinization occurs under low pressure-high temperature conditions. c) OCC source rock is slab of cold oceanic crust sub ducted under fresh crust. d) Such subduction occurs mostly where large density contrast between slabs exists. e) The link between OCCs and detachment normal faults requires support.","PeriodicalId":140386,"journal":{"name":"Environmental Sciences and Ecology: Current Research (ESECR","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130172273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From there, a model capable of synthesizing the behavior of the most relevant variables in the event of an extraordinary rainfall event was adjusted. The result was the definition of buffer areas or exosystemic protection in the interface. The testing and adjustment of this model defined a REP indicator that was proposed as an input in the planning of the sector. For validation, soil moisture permanence values from LWI were used. The derivative was calculated for each pixel value in the basin, for both dry and wet periods, and the areas with the lowest loss in both periods were compared with those with the highest retention obtained in the model.

For the present study, we constructed an enclosed and sealed terrarium with a variety of broadleaf plants and measured daily ionization and absolute humidity levels for 1 month compared to a similar container without plants. Methods: Twelve healthy, watered broadleaf plants were placed in a large 19-quart plastic container and sealed with snap closers. A similar but empty container was used as a control. Protocol 1: The time to reach maximum negative ion counts determined by introducing an ion counter into the canister and a hygrometer to measure humidity were monitored daily for 30 days.
