Pollinator type and secondarily climate are related to nectar sugar composition across the angiosperms
(Springer, 2017-08)
Pollinators are important agents of selection on floral traits, including nectar sugar composition. Although it is widely assumed that the proportion of sugars (mainly sucrose, glucose and fructose) in nectar reflects ...

Latitudinal analysis of rainfall intensity and mean annual precipitation in chile
(INST INVESTIGACIONES AGROPECUARIAS, 2012)
The study and analysis of precipitation has become a crucial tool in understanding the temporal and spatial behavior of water resources, in terms of availability and impact on extreme events. The objective of this study ...
The genetic effects of Late Quaternary climatic changes over a tropical latitudinal gradient: Diversification of an Atlantic Forest passerine
(Wiley Blackwell Publishing, Inc, 2011-05)
The increase in biodiversity from high to low latitudes is a widely recognized biogeographical pattern. According to the latitudinal gradient hypothesis (LGH), this pattern was shaped by differential effects of Late ...

Wetlands of the Magellanic Steppe (Tierra del Fuego, Argentina)
(Springer, 2009-09)
Our main objective was to classify vegetation and soils of wetlands in northern Tierra del Fuego (Argentina) along a latitudinal precipitation gradient within the Magellanic Steppe Zone. We presented the first detailed ...
Comparing green spaces provision and accessibility indicators over a latitudinal gradient and multiple climate zones
(ELSEVIER GMBH, 2023)
Monitoring urban green space (UGS) indicators is key to assessing progress against the UNs sustainable devel-opment goals (SDGs). Within these indicators, measuring the provision of UGS as well as its accessibility is ...
