The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

open access: yesOikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

First record of Mnemiopsis leidyi A. Agassiz 1865 in the Baltic Sea [PDF]

open access: yes, 2006
The invasive ctenophore Mnemiopsis leidyi was first recorded in the Kiel Bight (western Baltic Sea) on 17 October 2006 during a regular weekly sampling program. The M.

Investigating conservation performance payments alongside human–wildlife conflicts: The Swedish lynx and wolverine protection policies

open access: yesPeople and Nature, EarlyView.
Abstract Conservation performance payments are becoming an increasingly popular instrument to tackle human–wildlife conflicts. In Sweden, Sámi communities practicing reindeer husbandry receive performance payments as compensation for reindeer losses caused by lynxes and wolverines.

Key gaps remain in the definition and application of keystone species concepts for fisheries management: A systematic scoping review

open access: yesPeople and Nature, EarlyView.
Abstract A keystone species is one whose influence is disproportionate to its abundance, the absence of which would change the dynamics of an ecological or human community. Despite its widespread use in the scientific literature, there is a limited understanding of how the keystone concept is defined or measured, or applied in practice, and especially ...

Coastal up- and downwelling in the southern Baltic [PDF]

open access: yesOceanologia, 2005
A three-dimensional hydrodynamic model was used to determine 12 zones of upand downwelling in the southern part of the Baltic Sea.On the basis of a seven-year numerical simulation, the annual frequency of up- and downwelling events in various regions was analysed, their vertical velocity evaluated and the probability of their occurrence for different ...

When tiny convective spread affects a midlatitude jet: Spread sequence

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

UAVs unveil the role of small scale vegetation structure on wader nest survival

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

The study of using information and communication technology in Hungary and in the 27 countries of the EU [PDF]

open access: yes, 2012
The rate of personal computers and workstations in the 27 countries of the EU reached 96 %. The biggest backlog can be observed in the number of enterprises having and maintaining a website. Hungary's rate of 47 % is less than the EU average by 13 % and

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...
