Informed habitat choice in the heterogeneous world: ecological implications and evolutionary potential

Autor: Tolvanen, J. (Jere)

Animals live in a heterogeneous world where threats and abundance and quality of resources vary across space and time. Heterogeneity induces uncertainty in decisions that animals must make, e.g., where to breed. Adaptive decisions may be facilitated

Do large-scale associations in birds imply biotic interactions or environmental filtering?

Autor: Elo, M. (Merja), Kajanus, M. H. (Mira H.), Tolvanen, J. (Jere), Devictor, V. (Vincent), Forsman, J. T. (Jukka T.), Lehikoinen, A. (Aleksi), Mönkkönen, M. (Mikko), Thorson, J. T. (James T.), Maximilian G. R., V. (Vollstädt), Kivelä, S. M. (Sami M.)

Aim: There has been a wide interest in the effect of biotic interactions on species’ occurrences and abundances at large spatial scales, coupled with a vast development of the statistical methods to study them. Still, evidence for whether the effec

Conceptual preferences can be transmitted via selective social information use between competing wild bird species

Autor: Forsman, J. T. (Jukka T.), Kivelä, S. M. (Sami M.), Tolvanen, J. (Jere), Loukola, O. J. (Olli J.)

Concept learning is considered a high-level adaptive ability. Thus far, it has been studied in laboratory via asocial trial and error learning. Yet, social information use is common among animals but it remains unknown whether concept learning by obs

Choice of nest attributes as a frontline defense against brood parasitism

Autor: Moreras, A. (Angela), Tolvanen, J. (Jere), Morosinotto, C. (Chiara), Bussiere, E. (Elsa), Forsman, J. (Jukka), Thomson, R. L. (Robert L.)

Breeding- and nest-site choice is a behavioral strategy often used to counter negative interactions. Site choices before breeding prevent costs of predation and competition but have been neglected in the context of brood parasitism. For hosts of broo

Information collected during the post-breeding season guides future breeding decisions in a migratory bird

Autor: Tolvanen, J. (Jere), Morosinotto, C. (Chiara), Forsman, J. T. (Jukka T.), Thomson, R. L. (Robert L.)

Breeding habitat choice and investment decisions are key contributors to fitness in animals. Density of individuals is a well-known cue of habitat quality used for future breeding decisions, but accuracy of density cues decreases as individuals dispe

Interspecific information on predation risk affects nest site choice in a passerine bird

Autor: Tolvanen, J. (Jere), Seppänen, J.-T. (Janne-Tuomas), Mönkkönen, M. (Mikko), Thomson, R. L. (Robert L.), Ylönen, H. (Hannu), Forsman, J. T. (Jukka T.)

Background: Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has been suggested to drive niche segregation and local coexistence of species. Interspecific social information use

Reducing cuckoo parasitism risk via informed habitat choices

Autor: Tolvanen, J. (Jere), Forsman, J. T. (Jukka T.), Thomson, R. L. (Robert L.)

Brood parasitism incurs severe fitness costs for hosts. Diverse host adaptations to avoid parasitism exist at various stages of the host breeding cycle, but the literature suggests that egg-stage defenses are the most evolved. Fitness costs of parasi

Cuckoo parasitism in a cavity nesting host:near absent egg‐rejection in a northern redstart population under heavy apparent (but low effective) brood parasitism

Autor: Thomson, R. L. (Robert L.), Tolvanen, J. (Jere), Forsman, J. T. (Jukka T.)

Brood parasite — host systems continue to offer insights into species coevolution. A notable system is the redstart Phoenicurus phoenicurus parasitized by the ‘redstart‐cuckoo’ Cuculus canorus gens. Redstarts are the only regular cuckoo hosts
