Multi-centennial summer and winter precipitation variability in southern South America
2010
[1] We present the first spatially and temporally highly resolved gridded reconstruction of multi-centennial precipitation variability for southern South America (SSA). A novel reconstruction approach of deriving 10,000 ensemble members based on varying predictor networks and methodological settings allows the identification of spatiotemporal changes in SSA precipitation and associated uncertainties. The summer and winter reconstructions back to AD 1498 and AD 1590, respectively, provide new evidence for multi-centennial increase in summer precipitation and an opposing decrease in winter precipitation into the 20th century. The drying in winter is significant over large parts of SSA, wherea…
Water recycling in leaves of Lithops (Aizoaceae)
2016
Lithops plants consist of a pair of succulent leaves inserted on a short stem; each growing season young leaves develop in a cavity formed between the older pair. Young leaves can take up water from the older pair allowing the plant to maintain growth and leaf expansion even without external supply of water. Recycling water between vegetative organs is one of the possible adaptation strategies of plants under drought stress, but it had never been demonstrated experimentally in Lithops. The methodology used to verify the existence of water redistribution from old leaves to young leaves was fluorescence microscopy, using two dyes to follow the water pathway inside the plant: Sulforhodamine G …
Human adaptation strategies to abrupt climate change in Puerto Rico ca. 3.5 ka
2015
The connection between climatic change and social response is complex because change articulates a number of inter-related factors. Human decisions are filtered by social buffers – including social memory, risk perception, and cultural priorities – and the rate and scale of climate change is usually much larger than the scale of human decision-making. In this article, we provide information on climate change based on precisely dated speleothems with the response evident in archaeological sites that have radiocarbon date ranges within the same time frame. A stalagmite recovered from within the catchment area for aquifer recharge of the Pre-Arawak site of Angostura in Barceloneta, Puerto Ric…
Application of the SWAP model to predict impact of climate change on soil water balance in a Sicilian vineyard
2012
In Sicily, the increasing scarcity of quality water is leading to irrigation with saline water in soils having a considerable susceptibility to salinization and degradation. In this paper, water flow and solute transport in a Sicilian irrigated soil was simulated by using the SWAP model, and the simulated results compared to measured values of soil moisture and salinity. The investigation was carried out in a vineyard located in Sicily (Mazara del Vallo, Trapani Province) within the framework of the Project: Evolution of cropping systems as affected by climate change (CLIMESCO). The soil hydraulic parameters were obtained by inverse method based on multi-step outflow experiments. The result…
Stratégies d’adaptation face à la douleur chronique
2017
Chronic pain constitutes a challenge for patients. It makes them uneasy with regard to their personality, their corporality and their life balance, and leaves long-lasting effects on their experience as a patient. The development of adaptation strategies and resources to deal with chronic pain is therefore essential.
Mūsdienu Ukrainas imigrantu adaptācija Eiropas Savienībā un Kanādā.
2016
Autors, izmantojot starpdisciplināru pieeju, aplūko migrācijas situāciju Eiropas Savienībā un Kanādā, vairāk pētot migrācijas situāciju Latvijā un Ontārio, no migrācijas regulējumu, statistikas, adaptācijas un imigrantu integrācijas perspektīvām. Ņemot vērā to, ka ukraiņu imigrācija ir nozīmīga, tās pazīmes ir atspoguļotas no mūsdienu perspektīvas: dinamika laika gaitā, etnisko organizāciju loma, sociālās vides ietekme. Autors ir veicis kvalitatīvu pētījumu Latvijā un Ontārio, ar mērķi salīdzināt mūsdienu ukraiņu imigrantu adaptācijas procesus. Uzmanība ir vērsta uz to, lai spētu noteikt pievilkšanās-atgrūšanās migrācijas faktorus, problēmas, ar ko saskaras imigranti jaunā sabiedrībā: imigr…
