Survival of Kamchatka pink salmon as result of combined influence of density regulation and environmental factors
Authors: Feldman Mark G. , Shevlyakov Eugeny A.
Published: July 2021

Dynamics of stock abundance and survival is similar for the pink salmon populations from East Kamchatka and West Kamchatka, obviously because of the same large-scale environmental factors influence, as the Pacific Decadal Oscillation (PDO) and the Western Pacific pattern (WP) that correlate significantly with the pink salmon populations indices for various stages of the life cycle. The survival measured as the recruits number per parental stock (R/S) has a non-linear dependence on this environmental indices described by parabolic equations. These dependencies are used in reproductive models, which simulate observed fluctuations of R/S with high accuracy. Note that these environmental factors influence on the pink salmon survival is opposite for its odd and even generations. For example, high PDO value in November is unfavorable for survival of the pink salmons in East Kamchatka in the first year of their life (incubation) but favorable for survival of the same population in the second year (marine feeding) - that’s why strong and weak year-classes of pink salmon are alternated. Both PDO and WP indices have quasi-biennial periodicity that is a bit longer than the 2-year alternation of the pink salmon generations, hence favorable environments change their correspondence with odd or even generations from time to time, on average in approximately every 8 years. Similar regularities are supposed for other salmon species, as West Kamchatka coho salmon.

Some results of monitoring for the pink salmon hatchery stocks from the Aniva Bay (Sakhalin Island)
Authors: Stekol’Shchikova Marina Yu.
Published: July 2021

Several population parameters (length and dynamics of spawning run, size-sex composition, variability of morphological and physiological characteristics) are determined and indices of survival are calculated for the pink salmon hatchery stocks from the Aniva Bay of the 2008-2011 generations on the base of the cultured pink salmon differentiation by thermal marks on otoliths. The hatchery pink salmon begin their migration to the bay rivers in late July, together with the wild fish. Size-weight parameters of the fish and their variability are similar for the hatchery and wild stocks in this period, obviously because of low impact of hatcheries on natural reproduction and high portion of wild fish among the spawners used in the hatcheries (> 50 %). Mean portion of the hatchery-reared pink salmon on spawning grounds of the main rivers was 17.9 % in the 2010-2013, the coefficients of their return varied from 1.0 % to 6.4 % that was lower than for the wild fish.

Authors: Kuzin Alexey E.
Published: July 2021

Structure of commercial hunting on northern fur seal at Tyuleny Island is considered including effectiveness of podding, age-sex composition of the podded and captured animals, age structure of culled males, and reasons of culling. In total, the number from 2650 to 5099 of fur seals were podded during the harvest seasons of 1990-2008, 45.80 ± 2.17 % of them were killed and 54.20 ± 2.16 % were released. The bachelors prevailed among the podded animals, as well as in the bachelor rookeries (51.70 ± 2.56 %). The bulls were more numerous in the pod (35.80 ± 2.12 %) in compare with the half-bulls (10.20 ± 0.99 %) and the females (2.00 ± 0.85 %). Among the harvested animals, the bachelors prevailed, as well (93.50 ± 1.06 %), whereas the bulls, females, and half-bulls weren’t numerous (3.83 ± 0.87 %, 2.51 ± 0.67 %, 1.49 ± 0.29 %, respectively); frequency of the bulls and females captures changed from year to year. The most numerous age group of captured seals was the 3-year old animals (52.80 ± 1.60 %). All groups were presented among the culling animals, but the bachelors prevailed. The most common reason for culling was injuring of seals by commercial fishery wastes (scraps of fishing nets, ropes, packaging tapes, etc.): 64.20 ± 6.86 % of the culled animals were injured by the wastes.
Modelling of stock dynamics for spiny king crab Paralithodes brevipes at southern Kuril Islands using a finite-difference model with delay
Authors: Chernienko Igor S.
Published: July 2021

The information on fishery object limited by CPUE data and fragmentary data on age and size is sufficient for production models. However, this type of models is improper for long-living species, as crabs, because of problem with assumption on equilibrium stock. Describing dynamics of a single year-class, these models average the parameters for all generations that impedes to use them for assessment of crabs stocks. Finite-difference models with delay are more promising in this case. Deriso-Snute finite-difference model with delay was used for simulating of the spiny king crab biomass dynamics at southern Kuril Islands and forecasting of TAC for this species. Parameters of the model were estimated using the algorithm of sampling by scheme of Markov chain. The model is relatively simple and undemanding to data - time-series of commercial catch per effort is sufficient for its simplest version. Results of modeling are comparable with the results of cohort models.

Efficiency of scallop Mizuhopecten yessoensis cultivation in the Ussuri Bay (Japan Sea)
Authors: Gavrilova Galina S. , Kim Larisa N.
Published: July 2021

Data on cultivation of scallop Mizuhopecten yessoensis in the Ussuri Bay are generalized. The marine farms are located in the shallow waters at depths of 2-18 m, their plantations occupy different areas with different hydrodynamics. Complex structure of the plantations (collectors, cages and bottom facilities) is formed in the semi-closed Sukhodol Bay, but bottom plantations only for growing of scallop and sea cucumber are mounted in two other bays. The local broodstocks of scallop were formed by juveniles transported from the Posyet Bay, after that at least 20 million individuals of scallop spat were collected in three bays in 2000-2014, and their growing gave the total commercial output about 216 t (111 t in the Sukhodol Bay, 70 t in the Ilmovaya Bay, and 35 t in the Malye Kushi Bay). This is rather weak result that shows that the area has limited abilities for development of this type of aquaculture. The main reason was low density of spat on substrata: it never exceeded 200 ind./collector and did not increase during the farms development, so the farmers were forced to increase the number of collectors to obtain required number of spat; moreover, some years were unfavorable for collecting of juvenile scallops. There is concluded that environmental conditions in the eastern Ussuri Bay are not optimal for the scallop cultivation by extensive method.

Published: July 2021

Adaptive abilities of the microscopic red alga Porphyridium purpureum (strain PP-AB11, isolated from the northwestern Japan Sea) are investigated experimentally by its repeated cultivation under various water salinity. Under the salinity of 8 ‰, the growth of P. purpureum was inhibited (0.1 division/day) during the first four days though there were no morphological differences of the cells as compared with those in the control (mean cell size was 6.3±1.2 µm in both cases); the cell density increased to 85 % of the control value after 21 days exposure. Under the salinity of 4 ‰, the lag-phase was also 4 days but size of the cells increased (on average up to 7.8 ± 1.5 µm), the cell morphology changed including the cytoplasm retraction, and contraction and granulation of the chloroplasts; the cell density increased less (to 53 % of the control value) after 21 days exposure. Under the salinity of 2 ‰, changes of the cell morphology and density were the most prominent: density of viable cells decreased to 6 % of the control value after 4-days exposure, size of the cells increased on average up to 8.7 ± 1.6 µm due to hydration, granulation was noticed in the chloroplasts, and the cytoplasm became dense. Under the salinity of 0 ‰, all the cells died after 4 days. Being cultivated repeatedly, the alga was better adapted to low salinity: after 21-days exposure the cell density was 97 % of the control value under salinity of 8 ‰ and 84 % of the control value under salinity of 4 ‰, with the growth rate 0.5 divisions/day and without visible morphological differences of the cells as compared with those in the control. It was adapted even to salinity of 2 ‰: the cells morphology was restored though the growth rate after 21-days exposition was still lower than in the control because of serious deterioration of the cells. The growth rate and cell morphology did not significantly differ from the control after reinoculation of the culture, previously adapted to salinity of 2 ‰, into the medium with salinity of 32 ‰.

Authors: Smirnov Andrey A. , Ovchinnikov Victor V. , Elatintseva Julia A.
Published: July 2021

Data on age of mass maturing and biomass culmination for pacific herring from the Gizhiga-Kamchatka population in conditions of active fishery are presented. Dynamics of its age structure is considered for the periods before active fishery and after its renewal. After the fishery renewal, the portions of mature fish by age groups had increased and the age of mass maturing had decreased, the body length of mass maturing became smaller, the mean body length and weight had decreased for the majority of age groups, and the rate of maturing had increased for females. The established commercial measure corresponds well to recent biological structure of the population. There is concluded that the active fishery during five years has no negative impact on the state of the Gizhiga-Kamchatka population of herring.

Authors: Loboda Sergey V. , Zhigalin Alexander Yu.
Published: July 2021

The data of pelagic and bottom surveys on pacific herring in the northwestern Bering Sea obtained in 2010-2015 and its stock assessments by different methods are compared. Some biological parameters of the herring are presented and its spatial distribution and migrations are described. The pelagic surveys with stepped trawling and the bottom trawl surveys are concluded as the best for the herring stock assessment and biological characteristic. The stock state in the 2010-2015 is determined as high abundant due to mass migration of herring from the eastern Bering Sea to its northwestern part that starts in June under certain oceanographic conditions. Different modes of the herring feeding migration are revealed for periods of its high and low stock. The results are used for the herring fishery regulation in the northwestern Bering Sea.

Authors: Chalienko Maria O. , Kalinina Marianna V.
Published: July 2021

Population of pale sea urchin Strongylocentrotus pallidus in Peter the Great Bay is investigated. The samples for its size structure and distribution were collected at the depth from 5 to 700 m in July 2013, 2014 and in April 2015 and the samples for the state of gonads, intestines and age structure - at the depths of 41, 69, 280, 346, and 670 m in early April 2015. The size structure at different depths is significantly different: the large individuals with average size of 70.0 mm (portion of commercial ones 98 %) occupy mainly the middle shelf area with the depths of 55-100 m, deeper at the depths of 100-200 m the portion of commercial urchins is lower (67 % in 2014 and 92 % in 2015), and the continental slope (depth > 200 m) is occupied by mainly (77-96 %) non-commercial individuals with average size of 35.5 mm. Age of sea urchins was determined by the growth zones on plates of their shells processed by Jensen method and varied from 3 to 12 years. The growth rate of sea urchins from the shelf areas was approximately in 1.5 times higher as compared with those from the continental slope, primarily due to different conditions of feeding. The gonads cellular composition was defined for the samples of 50 cells per female. The cells were differentiated in the categories of oocytes proliferation, oocytes differentiation, and mature eggs, and the gonad maturity stage was determined by domination of these categories, taking into accounts the S. pallidus reproductive cycle. In spring, the sea urchins from the shelf areas (depths of 41 and 69 m) were generally more mature as compared with those from the continental slope (depths of 280 and 346 m). However, correlation between the gonadal index and depth of habitat was not significant because the mature females were sampled in any depth. Composition of intestinal content and food components were determined visually, looking the bolus under binocular microscope. The sea urchins intestines were mostly filled with detritus at the depth of 41 m, sponges (Suberites sp.) at the depth of 69 m (70 % of cases), and unedible substances as silt and sand at the depth of 280, 346 and 670 m, minor fractions were the algal litter, remains of crustaceans, and detritus.
Impact of changing oceanographic conditions on species composition and abundance of zooplankton on the fishing grounds at Cape Navarin and their importance for the Russian pollock fishery in the Bering Sea
Authors: Zuenko Yury I. , Basyuk Eugene O.
Published: July 2021

Seasonal and interannual variability of zooplankton in the area at Cape Navarin are considered on the base of long-term surveys. This area is the main fishing grounds for Russian pollock fishery in the Bering Sea. Species composition of zooplankton changes cardinally during the feeding period: large-size copepods prevail in summer, but euphausiids, mainly the krill Thysanoessa inermis - in autumn. Year-to-year changes of the zooplankton abundance are species-specific and driven by different environmental factors. The water circulation is crucially important for such allochtonous species as krill by transporting them from the spawning areas. Advection either from the south, i.e. from the continental slope (till 2006), or from the east and west, i.e. from the shelf (in 2007-2014), was observed in the last two decades that corresponded to replacing of relatively warm oceanographic regime by relatively cold regime and could be traced by dynamics of the ice cover and the cold water pool area on the eastern Bering Sea shelf. The advection from the slope provides the krill transport to the area at Cape Navarin, but conditions of the cold regime limit the transport. From the other hand, the cold oceanographic regime is favorable for reproduction of many zooplankton species, including krill, because of higher primary productivity. As the result, the krill and some other mass zooplankton species have a bell-shape dependence of their abundance on water temperature: they have the maximal biomass in relatively warm years within the cold periods and in relatively cold years within the warm periods. In the years with severe winters, the pollock starts its back migration early, in August-September because of seasonal depletion of copepods and lack of krill, while the years with warm winters are also unfavorable for long feeding of pollock in the Navarin area because of low abundance of many zooplankton species. «Moderate» conditions are optimal for long feeding of pollock in this area, when the Russian fishery continues here longer, till November-December, with the annual landings > 500,000 t (as in 1996-1999, 2001, 2007-2008).

Aim. To study the structure of comorbidities in HIV-infected patients who died in institutions of the penal system. Materials and methods. The material of the study was the data of a retrospective analysis of 515 clinical cases with fatal outcomes from diseases in the institutions of the Federal Penitentiary Service of Russia in the Udmurt Republic from 2004 to October 2020. The study group (group I) consisted of 91 patients from among the persons infected with HIV, the control group (group II) – patients with HIV-negative status (424 patients). Statistical processing of the material was carried out using the methods of variation statistics. Significance was assessed using the Pearson Chi-square test (χ2), Student's t test. During the study, the structure of concomitant diseases in cases of lethal outcomes was studied in dynamics. For the statistical processing of indicators and the implementation of a medium-term forecast (for three periods (years) ahead) of the values of the studied epidemiological indicators, the determination coefficient R2 was used. Results. As part of the in-depth analysis of mortality, it was proved that HIV-infected patients, unlike those with HIV-negative status, significantly more often suffer from diseases of the circulatory system (I00–I99), which were diagnosed on average in 47.1% of cases (χ2=11.557, p<0.001), diseases of the digestive system (K00–K93) diagnosed on average in more than half (58.3%) of clinical cases (χ2=12.829, p<0.001), diseases of the nervous system (G00–G99) diagnosed on average in 73.4% (χ2=74.151, p<0.001), as well as diseases of the urinary system (N00–N99), diagnosed on average in 20.8% of patients (χ2=7.993, p=0.005). With the implementation of the mid-term forecast, an increase in the structure of concomitant pathologies of diseases of the circulatory system (R2=0.4023) and diseases of the digestive system (R2=0.4807) is expected. The share of diseases of the nervous system will remain stably high (R2=0.3242). Conclusion. HIV-infected patients in penitentiary institutions are characterized by polymorbid conditions, which require timely diagnosis and therapy in order to reduce the risk of poor outcomes and disability.

Kidney cancer is one among the top 10 cancers. Renal cell carcinoma (RCC) is commonly known kidney cancer. Almost all clinically targeted drugs used in treating RCC have many aftereffects. To overcome this problem with herbal products, the present study is aimed to investigate the preliminary phytochemicals, antioxidants and selective cytotoxicity of aqueous leaves extract of Garcinia cambogia (GC)and Garcinia indica  (GI)on(HEK-293) human embryonic kidney cells and (A498)human renal carcinoma cells. The phytochemical analyses were done using standard protocols. In-vitro antioxidant activity was carried out using DPPH, FRAP, and Phosphomolybdenum assay. Anticancer activity on A498 kidney cancer cell line was evaluated by MTT assay and the selectivity index was calculated. Preliminary phytochemical analysis of GC and GI leaf extract divulged the presence of various phyto-constituents. GI extract revealed higher phenolic content while flavonoid content was more in GC extract compared to alkaloids and saponins. Both plant extracts exhibited higher antioxidant capacities based on the test performed.GC and GIleaf extract wasselectively cytotoxic in-vitro to (A498) human renal carcinoma cells and can be safely used against kidney cancer at 500 µM (GC extract)and 300 µM (GI extract). Selective index for GC and GI extract was15.9 and 2.4respectively. The results indicate that GC and GI extracts are a favourable antioxidant and anti-cancer agents for A498 human renal carcinoma cells. However, further studies to isolate the bioactive compounds responsible for these activities are underway and to explore their molecular mechanism.

Clinical significance of serum mir-21,ca153 and cea in breast cancer
Authors: Rostam Ali
Published: July 2021

The Objective: one of the essential regulators of carcinogenesis is MicroRNA-21 (miR-21). Yet little light has been shed on its effectiveness as a tumor marker compared to the conventional ones. Comparing the diagnostic value of established tumor markers in breast cancer (BC) such as carcinoembryonic antigen (CEA) and CA153 with circulating level of miR-21 is the aim of this study.Methods:The study included 89 BC patients. Amplification of the circulating levels of miR-21 and miR-16 done using real-time PCR qualitative detection, while electrochemiluminescence assays was used to detect circulating levels of CEA and CA153. The diagnostic sensitivity for BC was compared between the three.Results: The serum miR-21 levels were high significantly BC patients, as the latter had much higher levels (P<0.001). the CA153 and CEA sensitivities were 15.73% and 22.47% respectively, while miR-21 Sensitivity and specificity were 87.6% and 87.3%.Conclusion:in BC patients miR-21 exhibits far higher sensitivity for diagnoses than both CEA and CA153. Thus especially in the early stages of BC, miR-21 can become a potential indicator for diagnosis, albeit the clinical stage, PR and ER statuses were not correlated in this study.

Authors: Заполоцкий Е.Н. , Бабайлов С.П.
Published: July 2021

С помощью ЯМР исследованы температурные зависимости парамагнитных химических сдвигов в комплексе [Co(DTPA)]3–. Максимальная температурная чувствительность химических сдвигов d(δexp)/dT оказалась равной 0.68 м.д./K. Изученный комплекс характеризуется высокой температурной чувствительностью химических сдвигов в спектрах ЯМР с учетом полуширины самого сигнала (|CT|/W = 0.51 K−1) среди комплексов парамагнитных d-элементов. Комплекс [Co(DTPA)]3– можно рассматривать как перспективное соединение для дизайна термочувствительных ЯМР зондов в связи с определением локальной температуры в водных средах и перспективной диагностикой заболеваний с помощью МРТ технологий.

Синтезированы и охарактеризованы β-дикетонаты серебра [Ag(RC(O)CHC(O)R')]∞ с объемными терминальными заместителями: R = C(OCH3)(CH3)2, R' = CF3 (1), R = R' = C(CH3)3 (2). Комплекс 1 получен впервые. Строение соединений установлено методом РСА. Кристаллографические данные: для комплекса 1 — пространственная группа P–1, a = 5.8012(6) Å, b = 9.1717(10) Å, c = 9.9251(11) Å, α = 73.722(4)°, β = 78.377(4)°, γ = 87.336(4)°, V = 496.49(9) Å3, Z = 2, dвыч = 2.134 г/cм3, μ = 2.059 мм–1; для комплекса 2 — пространственная группа C2, a = 22.1700(6) Å, b = 5.84530(10) Å, c = 9.3249(2) Å, β = 104.9670(10)°, V = 1167.42(5) Å3, Z = 4, dвыч = 1.656 г/cм3, μ = 1.701 мм–1. Оба соединения — цепочечные координационные полимеры. Анионы координированы бидентатно-циклическим способом, один из карбонильных атомов кислорода и атом углерода в CH-группе выполняют мостиковую функцию. В комплексе 2 координационное окружение серебра представляет искаженную вакантную тригональную бипирамиду (КЧ = 4), в комплексе 1 — тетрагональную пирамиду за счет дополнительной координации атома кислорода метоксигруппы соседнего аниона (КЧ = 5). Проведено сравнение строения и термической стабильности синтезированных комплексов с ближайшим аналогом (R = C(CH3)3, R' = CF3), которое позволило выявить эффект терминальных заместителей в β-дикетонатном лиганде.
Efecto de la interacción social sobre el reconocimiEnto emocional facial en el adulto mayor
Authors: Barajas- Carballo Susana Melissa , Alvelais- Alarcón Marina
Published: July 2021

Esta investigación analizó el efecto de intervenciones para reforzar el reconocimiento emocional facial en adultos mayores. La muestra estuvo constituida por dos grupos conformados en total de 10 adultos mayores en edad de 60 a 95 años de edad. Un grupo estuvo integrado por n=5 el cual recibía estimulación cognitiva, ludoterapia y activación física, mientras que el otro fue conformado por n=5 adultos mayores que solo recibían interacción social. El reconocimiento emocional se evaluó mediante la aplicación de la tarea de reconocimiento de expresiones faciales emocionales de Ekman, P. et al. 2002 de la Evaluación Afectiva del Adulto Mayor de Alvelais, M. y Samaniego, J. Resultados: a partir del análisis realizado mediante la prueba T-student para muestras independientes, se comprobó la hipótesis nula, denotando que no existen diferencias significativas entre grupos [t= 1.19, p=0.28]. En relación al análisis de cada emoción, se obtuvieron diferencias significativas en la denominación de la emoción miedo [t (8) =3.39, p<0.01], lo cual indica que los adultos mayores que tienen intervenciones de estimulación cognitiva, ludoterapia y activación física presentan un mejor desempeño en el reconocimiento emocional del miedo (emoción negativa) frente a adultos mayores que solo tienen intervención de interacción social.

Authors: Rojas-Vite Gerardo , Mateos-Salgado Erik Leonardo
Published: July 2021

Se realizó un estudio piloto con 8 personas con hipertensión arterial bajo tratamiento farmacológico, pacientes de consulta externa del Hospital General de Pachuca, y 8 participantes voluntarios con presión arterial dentro de los parámetros normales. Se tomaron medidas de presión arterial sistólica y diastólica, índice de masa corporal, personalidad y estado afectivo. No se encontraron diferencias con significancia estadística en cuatro de los 5 factores de personalidad, excepto en el factor neuroticismo, el cual tuvo un nivel más alto en el grupo con hipertensión. El estado afectivo negativo y positivo fue equivalente en ambos grupos. Estos resultados son una guía para futuras investigaciones e intervenciones que tengan como fin promover la salud integral en el paciente con hipertensión arterial.

Published: July 2021

La violencia es un problema creciente en las instituciones educativas a nivel mundial y ha generado gran interés en el campo de la investigación educativa en las últimas décadas. Sin embargo en México son muy pocos los trabajos que se enfocan en esta problemática en las Instituciones de Educación Superior (IES), ya que la mayoría de estudios disponibles se enfocan principalmente a escuelas de educación básica, en donde se considera que la detección temprana de comportamientos violentos en los alumnos puede prevenir actos de maltrato en niveles de educación media y superior. Por tanto, uno de los objetivos de este análisis es conocer la magnitud real del problema de la violencia en los estudiantes de nivel superior y su posible relación con el rendimiento académico, así como el incremento de los actos violentos en donde los distintos actores educativos han participado.

Published: July 2021

El escuchar hablar acerca de la termodinámica nos genera una gran incógnita, al ser una palabra tan inmersa en la ciencia y compleja, damos por hecho que sólo se puede abordar en campos de especialización; sin embargo, está presente en nuestro entorno. Esta rama de la física tiene un aspecto práctico, puesto que se aplica para el análisis de sistemas termodinámicos. Un sistema termodinámico es una parte del universo físico a estudiar, a través de sus elementos, propiedades y cambios o procesos que ocurren en él a partir de la modificación de las variables como la presión, volumen y temperatura.

Al estar en contacto con estos sistemas, la necesidad de abordarlos y profundizar en ellos crece; por lo que la presente investigación tiene como propósito difundir información acerca de los sistemas termodinámicos con el fin de familiarizarnos para futuras aplicaciones pertinentes y casos prácticos en la industria.

Aproximación al mundo gráfico-sonoro de domingo lobato: Transcripción y análisis de sus siete Bagatelas para piano
Authors: Cosio Hernández María Eugenia
Published: July 2021

Domingo Lobato fue un prolífico, pero poco conocido compositor cuyas obras no han tenido difusión suficiente. Por ello, se pretende dar a conocer un poco más de su acervo compositivo mediante la exposición ejemplificada de su obra inédita Bagatelas. Los objetivos principales se cifran en la transcripción, estudio y análisis de los manuscritos, para con posterioridad ser susceptibles de ser interpretados y así darles la pertinente difusión.

El intrincado tratamiento estilístico que manifiesta la obra requirió de una metodología de estudio ecléctica. Para ello se recurrió aparte del análisis formal a la teoría gregoriana, armonía modal, armonía cuartal y armonía post-wagneriana.

Uno de los mayores aportes de Lobato radicó en la utilización de la ortodoxia compositiva de manera vanguardista, empleando los cánones estéticos y compositivos clásicos para crear un lenguaje sonoro novedoso y particular.

El presente trabajo representa el primer acercamiento a la obra de Lobato, desde una perspectiva analítica novedosa con fines de estudio, trascripción y difusión. Cabe mencionar que, tanto la obra de Lobato, como la de sus discípulos y coetáneos ha sido escasamente referida por la musicología actual.

Published: July 2021

El agua es un recurso prioritario de estudio en varias ramas de la ciencia, incrementado por las dinámicas sociales. Es un factor determinante en la fertilidad del suelo, afectando el desarrollo de los cultivos, su disponibilidad da sustento a los procesos biológicos; también ayuda a regular la temperatura del suelo. En la actualidad se busca monitorear la cantidad de agua disponible, para optimizar su uso y controlar las propiedades del suelo. En el presente trabajo se hace una revisión de las propiedades eléctricas del suelo a partir del uso de diferentes métodos e instrumentos para la medición de la humedad. Los instrumentos para medición de humedad basados en propiedades eléctricas son fácilmente adaptables para ser automatizados y operados en forma remota. Este tipo de instrumentos, aunque requieren de mantenimiento y calibración, poseen buena precisión y un corto tiempo de muestreo, lo que da factibilidad a su aplicación a las ciencias agrícolas en particular para su uso en zonas de difícil acceso.
