<p>The high Andean wetlands are considered fragile ecosystems that provide ecosystem services for the maintenance of biodiversity and economy. However, currently global threat climate change puts them at serious risk, which is why objective this study to determine spatial-temporal climatic variation Chalhuanca (Peru), during period 1986-2016. Landsat scenes were obtained dry season in years 1986, 1991, 1996, 2001, 2006, 2011, 2016, using remote sensing techniques area vegetation index...
High Andean wetlands are important ecosystems due to their ecosystem services. Carbon storage is a result of the low decomposition rate flooded soils and temperatures. The carbon content stored in high wetland Chalhuanca (Arequipa) was estimated value this service calculated. For purpose, 30 samples were taken at random, establishing three pools: aboveground biomass (leaves stems), belowground (roots) organic soil. obtained with an auger-type device; each sample dried 65°C for least 24 hours...
El género Liolaemus presenta una gran diversidad entre los tetrápodos actuales, al punto de corresponder segundo con mayor número especies válidas descritas del infraorden Iguania. En este trabajo, se describe nueva especie lagartija arenícola perteneciente subgénero Eulaemus, grupo montanus, procedente las lomas costeras Quilca, La Chira y Ocoña, todos en la provincia Camaná, departamento Arequipa, Perú. Para determinar el estatus taxonómico esta especie, analizamos caracteres morfológicos,...
Introduction: High Andean flamingos also known as parihuanas, are species of recurrent presence in the high areas which find this area an important resting, feeding and some cases breeding The recorded here correspond to Phoenicoparrus jamesi, andinus Phoenicopterus chilensis, latter being most abundant common. During censuses performed during 2018 2019, lake Salinas, Ramsar site, located within Reserva Nacional Salinas y Aguada Blanca Southern Peru, atypical behaviors these birds were a...
Water quality is an issue of global concern because the evident contamination sources this resource.In recent decades study inland waters has been oriented towards recovery and conservation these ecosystems, in sense abundant studies were carried out lotic systems, to a lesser extent lentic systems much more reduced way high Andean wetlands.This work represents one few such as are Chalhuanca bofedales.The wetlands provide important ecosystem services, among which stand water regulation,...
Plastic pollution in marine and coastal environments has been widely recognized as a growing environmental concern. particles generated mainly by the degradation of larger plastic debris have called microplastics (< 5 mm), which are being studied all regions world. In South America there constant increase research on this topic Pacific coast. Specifically, Peru, number publications also increased, but northern southern zones not well studied. Due to importance determining presence these...
Abstract The importance of knowing the effect advance urbanization on biodiversity is becoming increasingly important, so it necessary to increase number investigations in these environments. This study was conducted city Arequipa, Peru, trying cover urban, suburban and rural environments, relating effects richness abundance birds this gradient, finding during period a lower bird species urban environments with dominance some ( Columba livia Turdus chiguanco), while there were greater equity...
Las comunidades vegetales xerofíticas donde predomina Tillandsia, en los desiertos costeros de Perú y Chile, son dependientes la neblina proveniente del océano pacífico, por lo que presentan, a su vez, características únicas le permiten sobrevivir al singular ecosistema. La distribución tillandsiales el sur fue evaluada mediante técnicas teledetección, revisión herbarios, textos especializados exhaustivas salidas campo, así mismo, se relacionó presencia respecto altitud, pendiente...
Tropical dry forests are among the most threatened ecosystems worldwide, with severe deforestation and regeneration problems compounded by an increasing climate change threat. Lomas de Atiquipa in Peruvian–Chilean Coastal Desert (Atacama Desert) comprises one of these formations, mainly dominated Tara tree (Tara spinosa), which is a Neotropical legume high ecological commercial value. However, approximately 80% original area has been reduced deforestation. An restoration experience was...
El litoral rocoso es un ecosistema heterogéneo en el que se distinguen una franja supralitoral, zona mediolitoral y infralitoral, al reconocer a las especies de moluscos como indicadoras zonación vertical. Este trabajo contribuye conocimiento la riqueza distribución vertical los intermareales para provincia Islay, Arequipa, Perú. Se realizó búsqueda intensiva meses noviembre diciembre del año 2013, poder determinar establecieron tres cuadrantes 25 x cm lado distribuidos perpendicularmente...
Abstract. Luque-Fernández CR. 2019. Diet and behavior of the burrowing owl (Athene cunicularia) in Atiquipa, an ecosystem Lomas south Peru. Biodiversitas 20: 137-143. The study trophic behavioral habits is a fundamental aspect knowledge natural history species, especially for those that present wide range distribution have to adapt habitats available resources can find survive. diet Athene cunicularia were studied peculiar such as lomas formation, on arid coast southern analysis regurgitated...
Oxyrophus fitzingeri is distributed in Ecuador and Peru. In this study we present an extension of the geographical distribution for Peru, first record species department Arequipa. This new report was made Lomas de Atiquipa Private Conservation Area.
Macroinvertebrates of the Chalhuanca high Andean wetland (bofedal) is presented, which presents two aquatic environments, river and water pools within bofedal vegetation.This located in district Yanque (Caylloma, Arequipa) at 4300 meters, southern Peru.Aquatic macroinvertebrates wetlands such as these have been sparsely studied Peru other localities, especially region, added to their taxonomic complexity for identification.For this 32 families were identified, distributed 21 orders 12...

Tropical dry forests are among the most threatened ecosystems in world, with severe deforestation and regeneration problems compounded by increasing threat of climate change. Lomas de Atiquipa Peruvian-Chilean Coastal Desert (Atacama Desert) comprise one this type formation, mainly dominated Tara tree (Tara spinosa), that is a Neotropical legume high ecological commercial value. Nevertheless, around 80% its original surface was drastically diminished. In study we present an alternative...
Tillandsia purpurea is an endemic species of the Peruvian desert coast, where its main source water and nutrients supplied by ocean fog. It a poorly studied species, phenological changes in response to different abiotic factors, including temperature availability, are unknown. This study aims describe phases their relationship with some environmental factors fog, precipitation, temperature, humidity. was developed hyper-arid environment southern coast Peru. We evaluated fog available using...
Islands, islets, and guano capes provide a unique variety of habitats for seabirds. Their variability determines the structure dynamics community. Studies about temporal diversity habitat use these systems in southern Peru are lacking. The aim this study was to analyze abundance, composition, behavior seabirds at Punta La Metalera (El Faro) province Islay Arequipa region Peru. We recorded total 12 species. One is endemic Peruvian coast (Cinclodes taczanowskii), one considered endangered...
