Boreliozes neiropsihiatriskie aspekti
2020
Laimas slimība ir multifaktoriāla sistēmiska saslimšana, kas pacientam var radīt novājinošu stāvokli dažādās orgānu grupās atkarībā no individuāla trofisma. Neiropsihiatriskie aspekti Laimas slimībai ir maz pētīti Latvijā. Ir svarīgi apzināt plašo neiropsihiatrisko simptomu spektru, lai uzlabotušīs saslimšanas norisi Latvijā. Mērķis: Izpētīt un apzināt neiropsihiatriskos aspektus Laimas slimības pacientu vidū. Uzdevumi: Veikt anonīmu aptauju un apzināt, cik boreliozes pacientu cieš no neiropsihiatriskiem traucējumiem un kāds ir to raksturojums. Materiāli un metodes: Šķērsgriezuma pētījums, kurā brīvprātīgi un anonīmi piedalījās Laimas slimības slimnieku atbalsta grupas biedri no Facebook vi…
A Band Model of Cambium Development: Opportunities and Prospects
2021
More than 60% of tree phytomass is concentrated in stem wood, which is the result of periodic activity of the cambium. Nevertheless, there are few attempts to quantitatively describe cambium dynamics. In this study, we develop a state-of-the-art band model of cambium development, based on the kinetic heterogeneity of the cambial zone and the connectivity of the cell structure. The model describes seasonal cambium development based on an exponential function under climate forcing which can be effectively used to estimate the seasonal cell production for individual trees. It was shown that the model is able to simulate different cell production for fast-, middle- and slow-growing trees under …
Wood formation in pedunculate oak and its relation with climatic factors in Latvia
2013
Šajā darbā ir analizēta parastā ozola (Quercus robur L.) augšanas saistība ar klimatiskajiem faktoriem Latvijā (43 vietas), izmantojot dendrohronoloăijas un dendroekoloģijas metodes. Klimata ietekmes novērtējumam, izmantoja divus atšķirīgus gadskārtu mērījumus: gadskārtu platumu un pavasara koksnes traheju dobumu laukumu. Ozola augšana uzrādīja atšķirības gar austrumu-rietumu gradientu saistībā ar klimata kontinentalitāti. Balstoties uz šo gradientu Latvijas teritoriju var iedalīt divās daļās (rietumu un austrumu reģionā). Gadskārtu platumu rietumu reģionā, galvenokārt, ietekmēja pavasara un vasaras gaisa temperatūra, bet austrumu reģionā klimatisko faktoru, kas ir saistīti ar sausumu vasar…
Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range
2021
Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica 41: 50–88. The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified, of which 87% are above the treeline. The lakes hosting L. arcticus decrease in altitude from south to north, which results from its temperature preferences. The majority of the locations are at a lower lake air t…

Variabilità delle serie storiche di temperatura e precipitazione in Sicilia
2008
A regional analysis of longer time series of temperature and rainfall, in Sicily, was performed. Trends and rainfall-temperature correlation was investigated, finding tipical droughty behaviour.
Spatial and temporal variability of rainfall over the Republic of Djibouti from 1946 to 2017.
2021
20 pages; International audience; For the first time, the spatial and temporal variability of rainfall in the Republic of Djibouti is investigated using data from 14 weather stations over the period 1946–2017. Due to limited data availability, high-resolution long-term satellite rainfall products (CHIRPS, PERSIANN-CDR, TAMSATv3, ARC2) and ERA5 reanalysis also contribute to document time–space rainfall variability at monthly, seasonal and annual scales. Principal component analysis identifies two spatially coherent regions of rainfall variability in the east (coastal zone) and the west (inland zone) of the country. Annual rainfall amounts are everywhere very low (60–300 mm), but with contras…
Changes of total annual runoff distribution, high and low discharges in Latvian rivers
2009
Changes of total annual runoff distribution, high and low discharges in Latvian rivers The paper examines climate change impacts on the hydrological regime of nineteen different river basins in Latvia. Hydrological data series for the period of 1951-2006 were analysed for river basins of four hydrological districts: Western, Central, Northern and Eastern. Climate change has influenced the temporal and spatial distribution of total annual river runoff and high and low flows in Latvia at the turn of century. The results confirm the hypothesis that the main tendency in the run-off change is a decrease in spring floods and increase in winter. Generally, statistically insignificant long-term tre…
