The crucial role of seabirds in the enrichment nutrient-poor polar terrestrial ecosystem is well-known. However, no studies have examined potentially different impacts associated with piscivorous and planktivorous bird colonies on surrounding tundra soils. Therefore, we compared guano deposition physical chemical parameters soil near two large seabird colonies, one little auks (Alle alle) other comprising Brunnich's guillemots (Uria lomvia) kittiwakes (Rissa tridactyla). generated similar...
Despite a widespread recognition of the role seabird colonies in fertilization nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities are still lacking. Therefore, we studied community structure abundance springtails (Collembola) ornithogenic tundra near two large Hornsund, south-west Spitsbergen. We found considerably (5–20×) higher densities biomass Collembola vicinities both (the effect...
We studied the relative importance of several environmental factors for tundra plant communities in five locations across Svalbard (High Arctic) that differed geographical location, oceanographic and climatic influence, soil characteristics. The amount marine-derived nitrogen supplied by seabirds was locally most important influencing community. found a strong positive correlation between δ15N isotopic values total N content soil, confirming fundamental role matter to generally nutrient-poor...
Seabirds in the Arctic are known to link marine and terrestrial ecosystems. They feed sea breed on land, where they deposit enormous amounts of guano. Soil vicinity seabird colonies is much more enriched with nutrients as compared areas beyond their impact, which positively affects primary secondary production. Water bears (Tardigrada) microinvertebrates constitute a permanent ubiquitous faunal component polar regions. Here, we tested influence guano Tardigrada communities; established two...
The role of seabirds as sea-land biovectors nutrients is well documented. However, no studies have examined whether and how colonial that differ in diet may influence terrestrial vegetation. Therefore, the purpose study was to describe compare plant communities located vicinity two most common types seabird colonies Arctic, occupied by piscivorous or planktivorous species. Within 46 plots arranged four transects plankivorous (little auk, Alle alle) (mixed colony Brunnich's guillemot, Uria...
In the resource-limited Arctic environment, vegetation developing near seabird colonies is exceptionally luxuriant. Nevertheless, there are very few detailed quantitative studies of any specific plant species responses to ornithogenic manuring. Therefore, we studied variability polar scurvygrass Cochlearia groe nlandica individual biomass and leaf width along a influenced gradient determining environmental conditions for in south-west Spitsbergen. We found colony effect being paramount...
In the Arctic, areas close to seabird colonies are often characterized by exceptionally rich vegetation communities linked with high nutrient subsidies transported seabirds from marine environment land. These also support soil invertebrate of which springtails (Collembola) represent most abundant and diverse group. Our study focused on springtail community composition in vicinity (little auk, great skua glaucous gull) nesting different parts Svalbard (Magdalenefjorden, Isfjorden Bjørnøya),...
Abstract Marine birds and pinnipeds which come to land breed, rest moult are widely known fertilize adjacent terrestrial ecosystems, with cascading effects on vegetation other trophic levels. We provide a synthesis of the consequences allochthonous nutrient enrichment for invertebrate communities within around marine vertebrate aggregation sites sources in High Arctic Continental Maritime Antarctic, most nutrient-poor environmentally extreme parts polar regions. Using combination literature...
Solar radiation reflectance was analysed to characterize Arctic ornithogenic tun− dra developing in the vicinity of large breeding colony Brunnich's guillemots Uria lomvia and kittiwakes Rissa tridactyla at foot Gnalberget cliff (Hornsund, SW Spitsbergen). Radiometric method found be a useful tool for studying structure functioning plant formations. We measured four wavelengths: 554 nm (YG), 655 (RED), 870 (NIR) 1650 (SWIR) 10 plots situated along transect running from sea. Moreover, data...
Arctic terrestrial invertebrate biodiversity is generally poorly known, but the archipelago of Svalbard has one most up-to-date inventories its and freshwater faunas any region, offering a baseline for long term monitoring communities in space time. Since recent review fauna was produced 2014, knowledge this developed inventory here critically revised updated. Our aims are (1) to based on current taxonomic knowledge, (2) publish complete species inventory, including cross-referencing...
The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors structure microflora communities remain largely unclear. This study was conducted Hornsund Bay, which exhibits large variability physicochemical characteristics habitats, particularly with regard to availability nitrogen phosphorus. variability, a degree, caused by seabird colonies, fertilize nutrient-poor terrestrial...
Surveys of terrestrial microinvertebrate morphometry, especially spatial patterns body size at wider geographical scales, including the polar regions, are very scarce. In this study, we focused on Tardigrada, common limno-terrestrial microinvertebrates. Considering Bergmann's rule, originally formulated for endothermic animals, tested hypothesis that length tardigrades augments with increasing latitude and decreasing temperature. Since some our sampling areas adjoined seabird colonies, also...
Abstract In the High Arctic, nutrients are most limiting resources, so terrestrial vegetation is of low complexity and grows slowly. However, locally, large seabird colonies increase soil fertility by deposition faeces, supporting development rich fast-growing plant communities. Here, we assessed how affected ecological niche segregation plants, across fertilisation gradient. Study sites were located near five little auk colonies, distributed longitudinally Svalbard archipelago. We described...
Abstract The purpose of the present study was to determine link between planktivorous little auks ( Alle alle ) and their soil fertilization, concentration total, different forms phosphorus in surface layer High Arctic soils vascular plant composition tundra vegetation. Samples (0–10 cm) were collected along three pairs transects (affected unaffected by auks) at locations Spitsbergen (Svalbard). affected characterized a significantly higher mean Ptot (1.02–1.44 g kg −1 compared those not...
Phosphorus (P) is a very important constituent in both natural and managed ecosystems, which responsible for plant growth vegetation cover development. While numerous ecological studies concerning the impact of planktivorous seabirds on terrestrial ecosystems Arctic have been performed, no data are currently available about phosphorus forms occurring soils fertilized by their relationship with tundra vegetation. The aim present study was to determine link between little auks ( Alle alle )...
Seabirds constitute an important link between marine and terrestrial ecosystems, one of its manifestations being the transport organic matter from sea to breeding grounds.The main aim our study was determine impact gregarious planktivorous little auks on quantity chemistry soil along western coast Spitsbergen, Svalbard archipelago.Samples vicinity four colonies respective controls were investigated using elemental analyzers as well Fourier transform infrared spectrometer with attenuated...
