Simulating and Analysing Seabird Flyways: An Approach Combining Least‐Cost Path Modelling and Machine Learning

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 2, February 2025.
ABSTRACT Aim We develop and test a cost framework to simulate the flyways of migratory seabirds, considering various environmental factors such as wind support, crosswind, travel distance, and food availability. Using this framework, we simulate potential migratory flyways for arctic terns and compare these simulations with tracking data. Our aim is to

Strength of seasonality and type of migratory cue determine the fitness consequences of changing phenology for migratory animals

open access: yesOikos, Volume 2025, Issue 1, January 2025.
Phenological mismatch has been highlighted as a reason why climate change is causing declines of migratory populations. The likelihood of declines due to phenological mismatch might depend on what cues trigger migration. Migrants that use environmental cues (e.g.

Upwind or downwind: the spring arrival of Arctic TernsSterna paradisaeaat Troms, north Norway [PDF]

open access: yesRinging & Migration, 2016
This study was funded by Tromso University Museum. I also thank members of the local branch of the Norwegian Ornithological Society and members of the public who reported arrival dates to me or to www.artsobservasjoner.no. Without them this study would have been impossible.

COVER PHOTO: Rapid ocean warming in the Gulf of Maine drives shifts in the availability of preferred seabird prey, including herring (Clupea spp. or Alosa spp.) and hake (Urophycis spp.). Some terns in this region will provision their chicks with terrestrial insects when marine resources become scarce. Gownaris et al.

Mogelijke consequenties van reductie van de hoeveelheid discard voor N2000 instandhoudingdoelen [PDF]

open access: yes
Discards zijn overboord gezette bijvangst van vissersschepen. Volgens de Nederlandse Visie op herziening van het Gemeenschappelijk Visserijbeleid (GVB) zouden discards uitgebannen moeten worden.

Importance of marine prey to growth of estuarine tern chicks: evidence from an energetic balance model [PDF]

open access: yes, 1994
We assessed the effects of quality and quantity of prey species on the growth of Little Tern Sterna albifrons chicks raised in salinas (salt-pans), Algarve, Portugal. An energetic balance model was developed, which estimated the total amount of energy
