SENDERO QUISHUAR
In order to determine the orders of insecta and collembola classes in the Quishuar trail, the 15th September 2012, a preliminary
sample collection was done in El Boliche National Reserve. For this purpose, nine sampling spots were selected with a separation
distance of 100 m and an area of 1 square meter; in each spot a 10 minutes observation was performed in both sides of the spot and
the number of insects and collembolos was registered. After a manual recollection insects, they were released again. Excel and Past
version 2.4 packages was used to analyze the obtained data. Georeferencing was performed with a GPS garmin GPSMAP 78s and
the spot position was included using the open software Quantum GIS (Qgis), a GIS software tool Version 1.7.4. The results shown 7
orders of insects and one non identified collembola order inside the soil, herbaceous and bush substrates. The orders observed with
higher frequency were Diptera (insecta) and one of collembola classes. The study of similitudes of sampling spots revealed that the
higher percent of similitude is observed in soil and bush substrates.

SILICA DEPOSITION VESICLE
The presence of mineral deposition is very common in microorganisms, plants, mushrooms and mammals. This organisms are
an excellent natural model to study the relation between the principal parts involved in the process, the biopolymeric and mineral
phases. The importance of this kind of studies is the relation with nanotechnology. Being a relatively new science, nanotechnology
studies the chemical and physical phenomena is a scale under the 500 nanometers. When the system under study has a biological
significance, with active biologic structures, the term bionanotechnology is used. This is the case of the study of the biomineralization
in diatomeas seaweed. Due to the difficulty in the production of controlled micro and nanostructures containing silica (SiO2), this
study is relevant. The possible technological applications of this kind of crystals are drug liberation structures, photovoltaic cells
and high performance ceramic materials. Factors that affect the geometry, mechanical and physicochemical properties are poorly
understood, whereby this kind of studies are important. Understanding the interactions and processes involved in the production of
biological crystals could yield to a rational production of new and sophisticated nanostructured material with a broad application
in nanotechnology (hybrid semiconductors), biology and biomedicime (biomaterials, drug liberation structures). In the work we
establish a “bottom up” draft of the synthesis of “biosilica” by diatomeas emphasizing the impact in nanotechnology.

LA CRISIS AMBIENTAL Y LOS DERECHOS DE LA NATURALEZA: UNA VISIÓN DESDE LA ECOLOGÍA POLÍTICA

The environmental crisis that began during the Industrial Revolution and that hasworsened since the last 50 years of the XX Century,
has produced deep changes in the Planet. It has being proposed that we are facing a new geological era: the Anthropocene. The
extraction of natural resources and themobilization of materials and energy is the result of a predatory economy of the industrialized
countries to their ancient colonies. In this context, the human right to a healthy environment and free from pollution is not enough,
nor is the concept of sustainable development. In that sense, the Constitution of Ecuador made a radical change, when it recognizes
rights to nature and makes the Sumak Kawsay the road that we must transit to improve our relationship with our environment. This
implies that economic activities must respect the right of the maintenance and regeneration of the vital cycles, structure, functions
and evolutionary processes of nature.

This work was developed in cantón Arenillas, El Oro province, located in the south of Ecuador. The objective of this work was to
determine the presence of Arsenic and Mercury in commercialized milk which is obtained from local cattle. Milk samples were collected
from dairy cows and in local markets of Canton Arenillas. The samples were analyzed by Hydride Vapour Generation Atomic
Absorption Spectrophotometry after digestion, according to EPA and AWWA regulations. The results shown that the assessment of
Mercury exceeds 2.2 times the standard values established by the Ecuadorian Technical Standards 0009:2008 (NTE) 0.005 mg/kg in
average; while for arsenic, the presence of this metal did not exceed the value of 0.015 mg/kg, which is the limit allowed by the NTE
0009:2008.
