Full textThe objective of this research is to characterize the specific parameters of the forest-fog relationship and the spatial and temporal methodological components to estimate the contribution of fog water by interception in the Andean forest of the La Cascarilla Mountains. Tropical montane cloud forests (TMCF) are ecosystems of a high ecohydrological value since it increases water inputs by intercepting the droplets of air currents. Because many of its characteristics are related to the formation of clouds, it is possible to propose regional hydrometeorological analysis and floristic exploration to evaluate areas of TMCF. Thus, the rainfall balance method is chosen under the premise that the fog water that reaches the forest floor must be found as the difference between the rainfall in the open sky and the water that drains into the canopy. In addition, it is decided to restrict the field data collection period to the humid season due to better conditions to detect fog entries towards flows in the forest floor. For field data collection two stations are installed and the instruments and registration protocols are conditioned so that local stakeholders can access to manage the stations. Then, in the results analysis, GIS tools are used to corroborate the regional hydro meteorological conditions during field data collection and dispersion and correspondence analysis. In this way, the association between the records of the fog gauges and the rain gauges with the climate oscillations and routine observations is determined. The results show that there are days of records that respond to the main hypothesis about fog water entries that increase the drop compared to the gross rainfall. In this way the forest qualifies as a TMCF.

Full textOn our planet, much of the continental area has been forested for millions of years. In Peru, the coast, highlands and jungle, have large forests, which together occupy 51% of the territory. Dry forests are characteristic ecosystems of the northern coast of Peru, and its key species Prosopis pallida, which represents not only an ecological but also economic value to communities surrounding these ecosystems. This research focuses on the forests of Lambayeque, being defined as representations of dry forests of carob tree those located in the Pomac Forest Historical Sanctuary, the ACP Chaparrí and ACR Huacrupe La Calera. Currently, it is clear that deforestation is the strongest cause of the reduction of many forest species. This coupled with the rapid changes in land use, forest fires and climate change are affecting many human communities and populations of animals and plants. One species that is threatened by these factors is, precisely, carob tree, so conservation along the dry forest ecosystem in its fullness is a priority. Therefore, the objective of this thesis is to identify and propose what strategies are most appropriate to conserve and manage the dry forests in an integrated manner so that resources and services offered by these ecosystems could be valorized. A methodology based on conservation biogeography, which included methods of species distribution modeling (MDE), remote sensing and geographic information systems (GIS), was worked. The Maxent software, a modeling program based on the principle of maximum entropy, for the present potential of the carob tree distribution, and its potential future distribution (2050) under two scenarios RCP 2,6 and 8,5 was used, resulting in an unexpected increase in the potential of northern Peru to host the species. To understand the dynamics of dry forests in terms of changes in land cover, fire frequency and landscape fragmentation, GIS tools and remote sensing methods (such as NDVI) were used to perform a spatial and multi-temporal analysis, resulting in variations in coverage plant, but they tend to reduce the vegetation to recent years. Furthermore, there is a clear expansion of the agricultural frontier, mainly due to deforestation. Moreover, one cannot ignore the role of ENSO events in an area like this, since their effects influence the regeneration of forests. The field work consisted of two main parts. In first place, to obtain the importance value index (IVI) of the carob tree dry forest. The sampling method was the point – centered – quarter, obtaining a value of 53,01 for the carob tree, besides knowing the floristic composition of the forest, taking as main reference the ACR Huacrupe. In second place and finally, surveys and interviews with key players, park rangers and local people applied who confirmed the importance of the species to the maintenance of dry forests and as a contribution and economic support to various communities as well as the worrying situation of deforestation, illegal primarily for commercial purposes, habitat fragmentation, degradation and continuous reduction of carob trees.

Full textSpecies richness, abundance and habitat of anurans inhabiting the humid montane forests of Carpish (2720 – 2980 masl) (Provincia de Huánuco, Departamento de Huánuco) was studied between october 2001 and august 2002. Six sectors were established, these were distributed at different levels and constituted by the different types of habitats. The area was evaluated during the wet and dry seasons of the Andean region for 30 days, using two sampling methods: visual encounter surveys and pitfall traps. Eight anuran species were found, three are first records for the provincia de Huánuco and five potential new species for the science, two species were published recently and three in description process. From the data the abundance of most abundant genus, Eleutherodactylus, could indicate a decrease with the altitude, however there is not a significant relationship (R2= 0.458, p= 0.139), due to the scarce density of specimens. The anurans are related to the presence of four microhabitats: soil (moss and leaf litter), small plant, fern and bush, which help to maintain humidity and offer protection from the climatic activity (rain, wind and sun).

Full textDa a conocer la diversidad y distribución de las especies de roedores de los bosques montanos de Huánuco, se evaluaron 12 localidades: Chaupiloma, Ucumaria, Shogos, Hatuncucho, Galloganan, Chinchurragra, Iscarag, Campamento Regional, Campamento Provías, Campamento Ututo, Kenwarajra y Hatuncucho, por tres a cuatro días de muestreo. Se utilizó el método de muestreo por captura (trampas Victor y trampas Sherman), obteniéndose 368 especímenes pertenecientes a 10 especies: Akodon orophilus, Akodon mollis, Calomys sorellus, Microryzomys altissimus, Microryzomys minutus, Oligoryzomys andinus, Phyllotis andium, Thomasomys cf. kalinowskii, Thomasomys incanus y Thomasomys notatus. Se analizaron los datos mediante diferentes índices de diversidad, resultando Ucumaria la localidad más diversa según el índice de Rarefacción (E(S10) = 3.45). Posteriormente se realizó una determinación de hábitats por localidad y transectos, mediante nMDS (escala multidimensional no métrica) y UPGMA (agrupación con promedios de enlace), analizando la similaridad y disimilaridad de los grupos formados con SIMPER (promedio de porcentaje de similaridad). Los resultados indican que la similaridad varía en los diferentes grupos debido a la predominancia de algunas especies de roedores, siendo más comunes A. orophilus, A. mollis, Thomasomys cf. kalinowskii y T. incanus, lo que podría estar directamente relacionado con la complejidad del hábitat, siendo la localidad de Chinchurragra diferente a las demás principalmente por la presencia de A. mollis.

Full textA taxonomic study of the Scrophulariales is presented in the humid montane forests of Carpish, Huanuco department. The collects were realized between 1700 and 3100 m, following standard techniques of floristic studies. The taxonomic study consisted in the elaboration of keys for families, genera and species, and description, taxonomic analysis and geographic distribution for each one of the species. Four families, 20 genus and 38 species are reported; the most diverse family is Gesneriaceae with 21 species in 8 genus, followed by Scrophulariaceae with 12 species in 8 genus; Acanthaceae with 3 species in 3 genus and Lentibulariaceae with 2 species in 1 genus. Nomenclatural changes have been given in some species, with exception in the family Lentibulariaceae. The most diverse genus is Alloplectus, of the family Gesneriaceae, with 8 species. The species A. carpishensis, A. ichthyoderma and Utricularia unifolia, this last of the family Lentibulariaceae, can inhabit to more altitudes (until 3000 m). A. carpishensis is a new species to the science. Of the species studied in the forests of Carpish, 9 are endemic of the Peru, the majority (5) belong to the family Gesneriaceae. The species A. dodsonii and Columnea fuscihirta, of the same family, are new registrations for the Peruvian flora. Ten species enlarge their distribution range to the department of Huanuco.

Full text--- Análisis of stomach contents and the stomach morphology were performed for 5 species of sigmodontine rodents including Akodon orophilus, Microryzomys altissimus, Microryzomys minutus, Thomasomys notatus y Thomasomys kalinowskii from montane forest at Huánuco, Perú (from 2564 to 4445 m). Indices of niche breadth and overlap were calculated for diet. Consumption of arthropods (adults and larvae) was predominant in Akodon orophilus, comprising 90.1% of diet by volume. On the other hand, consumption of plant material was predominant in Thomasomys notatus (>89%) and Thomasomys kalinowskii (67.75 % from consumption of plant, mainly was seeds). Microryzomys altissimus and Microryzomys minutus had a clear tendency towards omnivory with high proportion of plants and arthropods (adults). Based on these data, niche breadth (Levins’ Index) ranged from 1.70 in A. orophilus these value suggest that this rodent acts as a “specialist” to 4.61 in T. kalinowskii showing that this specie do not discriminate among resources, thus this rodent acts as a “generalist”.

Full textDeforestation is a global problem whose scientific evidence only alarms the situation of forests over time. One of the forest ecosystems of Peru, with particular characteristics, but at the same time of little knowledge in the scientific community, are the dry forests of the north. Changes in land use are one of the main contributors to the deforestation of these forests, and their loss is one of the factors in the intensification of another global problem: climate change. The research seeks to identify and analyze the effects of deforestation in Lambayeque, both in the changes in physical and biological structure of these forests, as well as in the ecosystem-society relationship between these with the peasant communities. Lambayeque has different types of dry forest (savanna, hill and mountain), so the study area includes this diversity of dry forests and that fall under national protection and regional conservation categories: Refugio de Vida Silvestre Laquipampa, Área de Conservación Regional Huacrupe La Calera and Santuario Histórico Bosque de Pómac.The analysis of changes in coverage, fragmentation of the landscape and models of potential distribution of species due to climate change, show that deforestation goes beyond a process of massive devastation. Internally it includes consequences that affect several sectors, despite not having the magnitude of coverage or loss that other ecosystems. In addition, the local population, through the perception and knowledge, provides the basis to propose and establish strategies for the sustainable use of the forest resources of the dry forest.

Full textThe high Andean areas of Peru are the habitat of the genus Polylepis, an arboreal group of high ecological relevance that concentrates a high diversity of species and that is a source of different ecosystem services. Since ancient times its distribution has been affected by human activities, reason why at the moment its distribution has been reduced to small patches. In the future, due to climate change, its current extent could decrease. This research project had as main objective to determine the distribution of four species of Polylepis (P. weberbaueri, P. sericea, P. incana and P. racemosa), as well as of the genus, in the central Andes of Peru. The current distributions of the species were determined through the collection and georeferentiation of botanical collections in Peru. From this, a Model of Distribution of Species was generated at past, present and future time, applying different climatic variables with different global climate models through Maxent software. Finally, the sites potentially most suitable for the occurrence of the species and the genus Polylepis were found and analyzed in a present, past and future scenario, taking into account the factors that have influenced the distribution of the genus over time.

Full textIn the present study the composition was determined and floral diversity of the forest Macuya (Ucayali), through five plots transects of the 0.1 hectare each one. In the same way the density is analyzed and distribution of 232 plots for studies of floral diversity, established in the Peruvian humid forest. Additionally, the analysis of the floral diversity in the Peruvian humid forest is carried out, with the inventories recompiled of 155 plots of 0.1 and 1 hectare. On the forest Macuya, the characteristic elements reported for this forest, they are quite compatible with the flora of locating summoned to court in smaller altitudes, although comparatively they register smaller values. In the forest Macuya stands out the abundance of the Rubiaceae, family that dominates typically in strata of greater altitudes. In the same way, the area basal of the Bombacaceae was found clearly favored by the presence of individuals of high diameters of the species Matisia cordata. The increase in the number of species, in agreement the area of sample is expanded, is similar al registered in the Stratum Amazon Alluvial Plain; in such a way, that the behavior of the curves species-area, indicates that the size of the sample is appropriated. The floors sampled of the forest Macuya are formed by recent material, possibly of alluvial origin, and with washes floors characteristics. As for the density and distribution of the plots for studies of floral diversity in the Peruvian Humid Forest, it evidence that the establishment of these has been hardly concentrated on some areas. In contrast, great part of the tropical humid forests of the country they have a very low plots installation intensity, existing extensive zones of territory in which not plots have been established, constituting authentic empty in the knowledge of the flora and biological diversity. On the composition and floral diversity among the places, was observed an influence of the altitude of the locations on the number of families, kinds and species. The greater quantity of kinds and species report ranks of small distribution in the zone of study; only 33 species were registered in plots of the three strata. The composition of families is similar between the locations of the Alluvial strata and Premontano, differing with those of the Montano; the high number of rare species in this last, they indicate certain tendency to the specialization and endemism. The Analysis of comparative Correspondence among the different places exposes similar generic compositions for the majority of locations of the alluvial stratum; as soon as al Premontano and Montano, some associations among places with similar composition were presented.

Full textAnaliza la distribución de orquídeas en tres tipos de bosques de la amazonia sur peruana. El estudio se lleva a cabo en el Centro de Investigación y Capacitación Río Amigos (CICRA) ubicado en la desembocadura del río Los Amigos, en la Región Madre de Dios. Los tres tipos de bosques incluidos en el estudio son; el bosque de terraza inundable, el bosque de terraza alta y el aguajal; estos bosques son representativos de la zona de estudio. Para evaluar y colectar las orquídeas se considera las zonas de altura de Johansson y se hicieron colectas de sus forófitos (árboles hospederos). La identificación taxonómica de las orquídeas y sus forofitos se realiza en el Laboratorio de Gimnospermas y Monocotiledóneas, y en el Herbario San Marcos (USM), ambas forman parte del Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos. Se reportan 59 especies de orquídeas entre epifitas, acuáticas y terrestres. Se encentra que cada uno de los bosques estudiados tiene sus propias especies de orquídeas. Respecto al patrón de distribución vertical se encuentra que difieren dependiendo del tipo de bosque y hay mayor similitud entre zonas de alturas contiguas. Se evalúan 56 forófitos mayores de 10 cm DAP (diámetro a la altura del pecho), entre los cuales los grupos más importantes son las Moráceas y Arecáceas (palmeras). Se registra mayor abundancia de orquídeas en los arboles con mayor DAP y altura. Los patrones de distribución registrados son consecuencia de factores abióticos como la dinámica del agua, que influyen en los ecosistemas amazónicos.

Full textThis thesis analyzes the prior consultation associated with the regulations contained in the Forestry and Wildlife Law No. 29743, conducted from October 2014 to March 2015, a law which constitutes the first national public forestry policy –in application of the Prior Consultation Law- produced in consultation with the indigenous peoples who occupy almost 30% of Peruvian forests across 56% of the nation’s territory. This successful process of dialogue and negotiation was based upon what is known as Relational capacity, built through analysis based on four elements: (i) relationships and articulation, (ii) formal and informal rules of the game, (iii) provision of human resources and financing and (iv) leadership. This process strengthened the Peru’s forestry governance, five years after the unfortunate Baguazo incident (2009), which cost the lives of thirty-three Peruvians. The consensus achieved between the state and the indigenous people, developed with the relational capacity, enabled the implementation of the National Forestry Policy and its legitimization, as well as leading to the establishment of the Executive Council of the National Forestry and Wildlife Service (SERFOR), through which four representatives of Amazonian and Andean social organizations have participated in the sector’s decisional processes since 2016.

Full textThe eddy covariance method was used to determine the carbon fluxes, ecosystem respiration and gross primary productivity of a western Amazon forest, in the Madre de Dios región in Peru and its relationship with micrometeorological parameters, from November 2016 (rainy season) until October 2018 (dry season). A sonic anemometer, infrared gas analyzer, radiation, humidity and a temperature sensors were used on the platform of the SAGES flux tower, at 46 m. The compilation, processing and the analysis of data were done using the R programming language, and the commercial software packages Eddy Pro and TOVI. A 78,30% of valid data was recorded over a period of 541 days, between October 2016 and October 2018. The air temperatures ranged between 21,6 and 25,6°C while the relative humidity fluctuated around 80%. The distribution of wind patterns showed a predominant direction towards the NW and a speed interval between 0,1 to 1,4 m.s-1. The main evidence of turbulences, u*, recorded a mean value around 0,31 m.s-1 during day and around 0,14 m.s-1 during night. Throughout the day, the peaks of temperature, wind speed, temperature and the minimum of %RH were recorded between 12:00 and 14:00 h. Short wave radiation fluxes oscillated around 300 W.m-2 and for long wave around -40 W.m-2, with highest values in the dry seasons. For the 2016-2017 wet season, a net radiation flow was recorded at 156,98 W.m-2 and 137,76 W.m-2 in the dry season. For the 2017-2018 period, these values were 151,20 W.m-2 in the rainy season and 139,81 W.m-2 in the dry season. Photosyntethic Active Radiation (PAR) recorded a daily average between 300 and 400 μmol.m-2.s-1. The daily distribution indicates that the forest received radiation between 06:00 and 18:00 h, reaching maximum peaks around noon. During the night, the forest behaved like a net source of radiation. In the flux analysis, an average daily flux of CO2 was determined ranging around -5 μmol.m-2.s-1 for the wet season and -4 μmol.m-2.s-1 for the rainy seasons. Registered storage CO2 flux values were 2,03 μmol.m-2.s-1 in the wet seasons and 1,3 μmol.m-2.s-1 in the dry season. The Net Ecosystemic Exchange (NEE) oscillated between -2 and -1 μmol.m-2.s-1. The daily behavior, influenced by the activity of the boundary layer, indicated that the forest was a carbon sink during days and a constant source at nights. Around 6:00 am, the turbulence due to the entry of solar radiation into the atmospheric boundary layer caused a CO2 flush with a maximum between 6 and 9 μmol.m-2.s-1. In the flux and energy balance analysis, sensible heat (H) and latent heat (LE) were studied. On a monthly scale, H fluctuated around 20 W.m-2 and LE near 60 W.m-2, with higher values during the wet seasons due to greater cloudiness, availability of H2O and lower incoming radiation. On a daily basis, due to the presence of solar radiation, the highest heat flux was registered during the day and the peaks were reached at noon. The energy balance, as a correspondence between the net radiation and H + LE, showed slopes between 0,70 and 0,80. The loss of energy balance was caused by errors in the instrumentation, sampling, application of the turbulence filter and the presence of vertical energy reserves that were not considered and registered by the equipment. The calculation of nocturnal ecosystemic respiration (R) was determined from the quadratic hyperbolic regression of NEE vs. PAR. During the 2016-2017 period, R was in the range of 9,49 to 11,84 μmol.m-2.s-1, while in 2017-2018, it was located between 7,03 and 7,88 μmol.m-2.s-1. The magnitude of R was more intense in the rainy seasons due to promotion of heterotrophic respiration and higher humidity at soil level. Gross primary productivity (GPP) was calculated as the difference of NEE and R. The values indicated a net annual carbon fixation of 44,86 tons per hectare in the period 2016-2017 and 45,92 tons per hectare during 2017-2018. The impact of the micrometorological and physiological variables, including possible errors due to lack of data continuity, could had affected the averages in GPP. Finally, the behavior of the R was modeled using the maximum daily temperature in each season. The results showed a remarkable approximation to the experimental results, so there is the possibility of expanding this field in the search to predict the behavior of the forest in the future.

Full textThe goal of the following research was to identify the effects caused by a conservation and sustainable use of natural resources initiative in a natural protected area (NPA) and in the population settled inside. For this purpose, we analyzed the project developed by the nonprofit environmental organization Conservation International Alto Mayo Protected Forest Conservation Initiative (AMCI) located between the provinces of Rioja and Moyobamba in the Region of San Martin. The study is an intermediate diagnosis of qualitative nature that allowed us to obtain information about the effects that the AMCI had on its beneficiaries and the NPA conservation through in-depth interviews to the project main stakeholders. The sample was significative, and the chosen technique was the convenience sampling, a non-probability sampling technique where subjects were selected because of their convenient accessibility. To analyze the perception of the 3 main stakeholders of the project, 18 in-depth interviews were conducted to the beneficiaries, the NPA and CI staff. The research allowed us to know that among the main effects of the ICAM, it stands out that the beneficiary population has been empowered in the use of sustainable agricultural practices through the training workshops given, the technical assistance and the use of demonstration plots developed by the project, which has meant a greater perception of wellbeing and contribution to the care of the environment, given that they no longer cut down the forest, and on the contrary use smaller areas of crop and reforest the degraded areas.

Full textManifiesta el uso de algoritmos de árboles de decisión y bosques aleatorios como instrumentos matemáticos y estadísticos-heurísticos para la predicción de fechas óptimas en evaluación de tizón tardío. Dichos algoritmos utilizan los índices de ganancia de información (entropía de la información) y los índices de Gini para ajustar al máximo la predicción. Para el desarrollo y análisis de los resultados de los árboles de decisión se utilizan las implementaciones conocidas como C4.5 y CART; mientras que para los bosques aleatorios se emplea RandomForest.

Full textDetermina el nivel de educación ambiental de los miembros de la Asociación de Conservación Ecológica Comunal los Bosques de Pailayco y propone un programa educativo para la conservación de recursos naturales en el distrito de Picota, 2015. La metodología está basada en un enfoque cualitativo de diseño no experimental y de tipo descriptivo-propositivo puesto que concluirá con una propuesta enfocada en la educación ambiental sobre la conservación del Bosque de Pailayco. La muestra está conformada por 15 pobladores de la Asociación de Conservación Ecológica Comunal los Bosques de Pailayco. Se realiza una propuesta en la que se hace hincapié en promover las capacitaciones y talleres dirigidos a los pobladores con la finalidad de educarlos y construir una conciencia ambiental más sólida que sea de beneficio para el medio que les rodea. Una de las principales conclusiones a la que se llega es que la educación ambiental de los pobladores del distrito de Picota es medianamente adecuada ya que actualmente existen socios y asociaciones que les brindan capacitaciones e información sobre la importancia de la conservación de recursos naturales especialmente del Bosque de Pailayco. A pesar de ello aún existen pobladores de la misma comunidad y de otras comunidades que realizan tala de árboles y caza de animales.
