Abstract Worldwide climate‐driven shifts in the distribution of species is special concern when it involves habitat‐forming species. In coastal environment, large Laminarian algae—kelps—form key ecosystems that support complex and diverse food webs. Among kelps, Macrocystis pyrifera most widely distributed provides essential ecosystem services. This study aimed to establish main drivers future distributional changes on a global scale use them predict habitat suitability. Using models (SDM),...
Large-scale regional phenomena and global climate trends may alter the freshwater discharge of large Patagonian rivers could modify local circulation patterns in ways that influence phytoplankton dynamics. Modifications detected streamflow regime Puelo River (41.5° S, Patagonia, Chile) recent decades affect regularity seasonal blooms Reloncaví Fjord. We examined occurrence/frequency spring–summer autumn Fjord with respect to inter-annual changes streamflows from 2003 2011. Surface...
Rapid adaptation during invasion has historically been considered limited and unpredictable. We leverage whole-genome sequencing of >2600 plants across six continents to investigate the relative roles colonization history worldwide Trifolium repens. Introduced populations contain high levels genetic variation with independent histories evident on different continents. Five large structural variants three chromosomes exist as standing within native range, exhibit strong signatures parallel...
Abstract Aim We assess the spatial distribution of a suite coastal biophysical characteristics and how their variability is related to geographic range diverse assemblage benthic species with different larval dispersal strategies. Location South‐eastern Pacific ( SEP ) coast between 18°20′S 42°35′S. Methods Biophysical was assessed using chlorophyll‐a concentration, sea surface temperature signal turbid river plumes derived from MODIS onboard Aqua satellite. established dominant components...
Species of the genus Ulva (Chlorophyta) are regarded as opportunistic organisms, which efficiently adjust their metabolism to prevailing environmental conditions. In this study, changes in chlorophyll-a fluorescence-based photoinhibition photosynthesis, electron transport rates, photosynthetic pigments, lipid peroxidation, total phenolic compounds, and antioxidant were investigated during a diurnal cycle natural solar radiation summer (for 12 h) under two treatments: photosynthetically...
This study assessed natural variation in the macroinvertebrate assemblages (MIB) and water quality one of main basins with largest agricultural activities Chile (Aconcagua River Basin). We sampled throughout annual cycle; nine sampling sites were established along basin, classifying according to area coverage as least-disturbed, intermediate, most-disturbed. collected 56 taxa entire area. Multivariate analysis shows significant differences among three disturbance categories different...
The coastal ocean off western Patagonia is one of the main regions with high freshwater inputs from rivers, rain, and glaciers in Southern Hemisphere. This study conducts an analysis seasonal interannual variations sea surface salinity meridional geostrophic transports, specifically focusing on Cape Horn Current, using improved satellite-derived data (SSS) velocities spanning ∼11-year period (September 2011–August 2022). Our results reveal a clear minimum band between 42–54°S associated...
Surface oceanic fronts are regions characterized by high biological activity. Here, Sea Temperature (SST) analyzed for the period 2003–2019 using Multi-scale Ultra-high Resolution (MUR) SST product in northern Patagonia, a coastal region with environmental variability through river discharges and upwelling events. gradient magnitudes were maximum off Chiloé Island summer fall, coherent highest frontal probability area, which would correspond to formation of front meridional direction....
The central and northern Chilean coasts are part of the Humboldt Current System, which sustains one largest fisheries in world due to upwelling. There several upwelling focal points along coast; however, from a physical standpoint, region between 39° 41° S has not been studied detail despite being most productive zones for pelagic extraction Chile. Here, we evaluated seasonal variability coastal off central-southern Chile using principally daily sea surface temperature (SST) wind (SSW),...
Western Patagonia harbors unique and sparsely studied terrestrial ecosystems that are threatened by land use changes exposure to basin-scale climatic variability. We assessed the performance of two satellite vegetation indices derived from MODIS–Terra, EVI (Enhanced Vegetation Index) NDVI (Normalized Difference Index), over northern southern sectors Chiloé Island System (CIS) advance our understanding dynamics in region. Then we examined their time-varying relationships with indicative...
Resumen.-Las imágenes satelitales son una poderosa herramienta para describir estructuras espaciales a meso y macroescala, ayudando de esta manera en la comprensión los procesos físicos-biológicos que ocurren el océano.El objetivo este estudio fue establecer variabilidad espacial (horizontal) temporal (estacional) biomasa autotrófica medida como concentración clorofila satelital (Clo-a) Mar Interior Chiloé (41,0-43,5ºS).Aproximaciones percepción remota (MODIS) geoestadísticas (Variogramas)...
The coastal region off Chilean Patagonia has been poorly studied due to the lack of available observations. Here we analyzed, by very first time, biogeochemical (BGC) data elucidate role that biological and physical processes play on nitrate, oxygen, pH hydrographic variables, along a salinity gradient central Patagonia. Argo float profiles covering upper ocean from December 2015 July 2019 reveal offshore waters are characterized low temperatures high salinities related oxygen medium-high...
Over the last century, climate change has impacted physiology, distribution, and phenology of marine terrestrial primary producers worldwide. The study these fluctuations been hindered due to complex response plants environmental forcing over large spatial temporal scales. To bridge this gap, we investigated synchrony in seasonal phenological activity between climatic variability across northern Patagonia. We disentangled effects on biological local processes using advanced time-frequency...
Resumen.-La cadena de islas incluyendo Desertores-Apiao y Quemchi situada en el Mar Interior Chiloé, la Patagonia chilena norte (41-44°S), actúa como una barrera natural para flujo agua dirección norte-sur que influye intercambio circulación entre las micro cuencas sur.La cuenca se caracteriza por dominio aguas estuarinas superficiales mientras sur encuentra afectada Subantárticas Ecuatoriales Subsuperficiales desde océano costero adyacente.Esta situación determina diferencias claves...
