Influencia humana en las fluctuaciones poblacionales de erizos de mar
(Universidad de Costa Rica, 2017)
First record of Mobula japanica (Rajiformes: Myliobatidae) from the south-eastern Pacific Ocean
(2012)
The spinetail devilray Mobula japanica was recorded for the first time in the south-eastern Pacific Ocean, from a single beach-washed specimen examined at Bahía Inglesa, Chile. The presence of this temperate-tropical species ...
Distribución espacio-temporal de las asociaciones de larvas de peces en el norte del Golfo de California
(2016-10-10)
Los requerimientos ambientales que promueven el éxito reproductivo de los peces
son una combinación de varios factores, tanto físicos como biológicos que influyen
en diferentes escalas espaciales y temporales. Por esta ...
Sea-surface temperatures of the southwest Pacific Ocean during the Last Glacial Maximum
(AMER GEOPHYSICAL UNION, 2000-02-01)
The southwest Pacific Ocean covers a broad range of surface-water conditions ranging from warm, salty water in the subtropical East Australian Current to fresher, cold water in the Circumpolar Current. Using a new database ...
Revisiting the diversity and distribution of the ophiuroids (Echinodermata: Ophiuroidea) from Peru
(Magnolia Press, 2020)
While the Ophiuroidea of Peruvian waters have long been studied, there exists inconsistencies regarding taxonomy and spatial distribution records. Based on literature review and museum records, we provide an updated checklist ...
Interplay between climate and hydrogeomorphic features and their effect on the seasonal variation of dissolved organic matter in shallow temperate lakes of the Southern Andes (Patagonia, Argentina): a field study based on optical properties
(John Wiley & Sons Inc, 2017-10)
This study analyses the effects of the interplay between climate seasonality and hydrogeomorphic (HGM) lake features on dissolved organic matter (DOM) properties in two neighbouring shallow lakes of Andean Patagonia with ...
Hydro-biogeochemical processes in Greenland Ice Sheet catchments: nutrient dynamics, chemical weathering and wider impactsHydro-biógeochemical processes in greenland ice sheet catchments: nutrient dynamics, chemical weathering and wider impacts
(2017)
Global warming has led to significant increases in melt rates of the Greenland Ice Sheet (GrIS)
and runoff since the beginning of 1990, and the GrIS is expected to be a major contributor to
global sea level rise in the ...
High predation is of key importance for dominance of small-bodied zooplankton in warm shallow lakes: Evidence from lakes, fish exclosures and surface sediments
(Springer, 2011-06)
The mean body size of limnetic cladocerans decreases from cold temperate to tropical regions, in both the northern and the southern hemisphere. This size shift has been attributed to both direct (e.g. physiological) or ...
The primary sources of carbon loss during the crop-establishment period in a subtropical Oxisol under contrasting tillage systems
(Elsevier B.V., 2011-12-01)
The physical protection of mineralizable carbon (C) in aggregates has been identified as the primary mechanism of soil C stabilization. Therefore, it is possible to hypothesize that the disruption of aggregate by soil ...
