Barrier crossings and winds shape daily travel schedules and speeds of a flight generalist
2021
External factors such as geography and weather strongly affect bird migration influencing daily travel schedules and flight speeds. For strictly thermal-soaring migrants, weather explains most seasonal and regional differences in speed. Flight generalists, which alternate between soaring and flapping flight, are expected to be less dependent on weather, and daily travel schedules are likely to be strongly influenced by geography and internal factors such as sex. We GPS-tracked the migration of 70 lesser kestrels (Falco naumanni) to estimate the relative importance of external factors (wind, geography), internal factors (sex) and season, and the extent to which they explain variation in trav…
The role of extrinsic and intrinsic factors on departure decisions of a long-distance migratory passerine
2013
[EN] Factors determining departure decisions of migrants from a stopover site can be extrinsic and/or intrinsic but the relative role of each of these factors on departure decisions is still poorly known. Date and wind should be the main factors determining departure decisions in a long-distance migrant, which is expected to minimise duration of migration. Date was considered as an intrinsic factor and wind as an extrinsic one. We analysed the capture-recapture data of a long-distance migrant European songbird, the sedge warbler Acrocephalus schoenobaenus,from a stopover site in northern Iberia during the autumn migration period to quantify the relative importance of several factors on emig…
Atskaišu sistēma pašnodarbinātām personām
2022
Kvalifikācijas darba ietvaros ir izstrādāta un aprakstīta tīmekļa lietotne atskaišu veikšanai pašnodarbinātām personām. Sistēma izstrādāta, izmantojot PHP programmēšanas valodas satvaru Laravel un JavaScript programmēšanas valodas satvaru Vue.js. Lietotne ļauj lietotājiem veidot klientu profilus, glabāt informāciju par paveiktajām darbībām un pēc lietotāja izvēlētajiem kritērijiem skatīt kopsavilkumu diagrammas veidā. Tīmekļa lietotnes galvenais mērķis ir sniegt lietotājiem vienkāršotu alternatīvu un draudzīgu lietošanā sistēmu uzskaites veikšanai, apvienojot iespēju glabāt informāciju un veikt pārskatus vienā vietā.
