Glass eel migration in an urbanized catchment: an integral bottleneck assessment using mark-recapture Mov. Ecol. (IF 4.1) Pub Date : 2024-02-15 A. B. Griffioen, T. Wilkes, O. A. van Keeken, T. van der Hammen, A. D. Buijse, H. V. Winter
Diadromous fish such as the European eel (Anguilla anguilla L.) are hampered by a high density of barriers in estuaries and freshwater systems. Modified and fragmented waterbodies lack tidal flows, and habitat may be less accessible and underutilized compared to free-flowing rivers and estuaries. With rising sea levels and increased occurrence of droughts, the number of barriers may further increase

Multi-isotope (δ2H, δ13C, δ15N) feather profiles and morphometrics inform patterns of migratory connectivity in three species of North American swallows Mov. Ecol. (IF 4.1) Pub Date : 2023-08-01 Keith A. Hobson, Kevin J. Kardynal
Aerial insectivorous birds have suffered steep population declines in North America over the last 60 years. A lack of information on migratory connectivity between breeding and non-breeding grounds for these species limits our ability to interpret factors affecting their population-specific trends. We determined likely Latin American non-breeding regions of Bank (Riparia riparia), Barn (Hirundo rustica)

Modelling the timing of migration of a partial migrant bird using ringing and observation data: a case study with the Song Thrush in Italy Mov. Ecol. (IF 4.1) Pub Date : 2023-08-01 Roberto Ambrosini, Simona Imperio, Jacopo G. Cecere, Alessandro Andreotti, Lorenzo Serra, Fernando Spina, Niccolò Fattorini, Alessandra Costanzo
The study of the timing of migration is fundamental to the understanding of the ecology of many bird species and their response to climate change, and it has important conservation and management implications e.g., for assessing the hunting seasons according to the EU Directive 2009/147/EC (Birds Directive). We developed a new method for the analysis of ringing data (both first capture and re-encounters)

Variation in herbivore space use: comparing two savanna ecosystems with different anthrax outbreak patterns in southern Africa Mov. Ecol. (IF 4.1) Pub Date : 2023-07-31 Yen-Hua Huang, Norman Owen-Smith, Michelle D. Henley, J. Werner Kilian, Pauline L. Kamath, Sunday O. Ochai, Henriette van Heerden, John K. E. Mfune, Wayne M. Getz, Wendy C. Turner
The distribution of resources can affect animal range sizes, which in turn may alter infectious disease dynamics in heterogenous environments. The risk of pathogen exposure or the spatial extent of outbreaks may vary with host range size. This study examined the range sizes of herbivorous anthrax host species in two ecosystems and relationships between spatial movement behavior and patterns of disease

Acoustic accelerometer transmitters and their growing relevance to aquatic science Mov. Ecol. (IF 4.1) Pub Date : 2023-07-27 Robert J. Lennox, Sindre H. Eldøy, Lotte S. Dahlmo, Jordan K. Matley, Knut Wiik Vollset
There has recently been great interest in the use of accelerometers onboard electronic transmitters to characterise various aspects of the ecology of wild animals. We review use cases and outline how these tools can provide opportunities for studying activity and survival, exercise physiology of wild animals, the response to stressors, energy landscapes and conservation planning tools, and the means

Soaring migrants flexibly respond to sea-breeze in a migratory bottleneck: using first derivatives to identify behavioural adjustments over time Mov. Ecol. (IF 4.1) Pub Date : 2023-07-27 Paolo Becciu, David Troupin, Leonid Dinevich, Yossi Leshem, Nir Sapir
Millions of birds travel every year between Europe and Africa detouring ecological barriers and funnelling through migratory corridors where they face variable weather conditions. Little is known regarding the response of migrating birds to mesoscale meteorological processes during flight. Specifically, sea-breeze has a daily cycle that may directly influence the flight of diurnal migrants. We collected

Multispecies fish tracking across newly created shallow and deep habitats in a forward-restored lake Mov. Ecol. (IF 4.1) Pub Date : 2023-07-27 Casper H. A. van Leeuwen, Joep J. de Leeuw, Olvin A. van Keeken, Joey J. J. Volwater, Ferdi Seljee, Roland van Aalderen, Willie A. M. van Emmerik, Elisabeth S. Bakker
Freshwater fish communities typically thrive in heterogenous ecosystems that offer various abiotic conditions. However, human impact increasingly leads to loss of this natural heterogeneity and its associated rich fish communities. To reverse this trend, we need guidelines on how to effectively restore or recreate habitats for multiple fish species. Lake Markermeer in the Netherlands is a human-created

Movement and behavioral states of common carp (Cyprinus carpio) in response to a behavioral deterrent in a navigational lock Mov. Ecol. (IF 4.1) Pub Date : 2023-07-26 Maggie Raboin, John M. Plumb, Matthew D. Sholtis, David L. Smith, P. Ryan Jackson, Jose M. Rivera, Cory D. Suski, Aaron R. Cupp
Freshwater ecosystems are some of the most affected by biological invasions due, in part, to the introduction of invasive carp worldwide. Where carp have become established, management programs often seek to limit further range expansion into new areas by reducing their movement through interconnected rivers and waterways. Lock and dams are important locations for non-physical deterrents, such as carbon

Animal behaviour on the move: the use of auxiliary information and semi-supervision to improve behavioural inferences from Hidden Markov Models applied to GPS tracking datasets Mov. Ecol. (IF 4.1) Pub Date : 2023-07-24 Sarah Saldanha, Sam L. Cox, Teresa Militão, Jacob González-Solís
State-space models, such as Hidden Markov Models (HMMs), are increasingly used to classify animal tracks into behavioural states. Typically, step length and turning angles of successive locations are used to infer where and when an animal is resting, foraging, or travelling. However, the accuracy of behavioural classifications is seldom validated, which may badly contaminate posterior analyses. In
