It is generally assumed that an investment into cognitive abilities and their associated cost is particularly beneficial for long-lived species, as a prolonged lifespan allows to recoup the initial investment. However, ephemeral organisms possess astonishing cognitive abilities too. Invertebrates, for example, are capable of simple associative learning, reversal learning, and planning. How can this discrepancy between theory and evidence be explained? Using a simulation, we show that short lives can actually select for an increase in learning abilities. The rationale behind this is that when learning is needed to exploit otherwise inaccessible resources, one needs to learn fast in order to utilize the resources when constrained by short lifespans. And thus, increased cognitive abilities may evolve, not despite short lifespan, but because of it.

Behavioural consistency in the dyeing poison frog, Dendrobates tinctorius Alanen, Emmi (2020)The behaviour of an individual organism is a combination of previous experiences and genetic factors. In some situations, a behaviour of an individual may be repeatable or consistent. For my Master’s thesis, I studied the ...
New insights on the role of ecology and life-history in social evolution Avila, Piret (University of Jyväskylä, 2017)Biological altruism, deﬁned as a behaviour that beneﬁts others at an apparent cost to the focal individual, is found abundantly across diﬀerent levels of biological organization. While kin selection has been useful for ...
The joint evolution of learning and dispersal maintains intraspecific diversity in metapopulations Liedtke, Jannis; Fromhage, Lutz (Wiley-Blackwell, 2021)The evolution of dispersal tendencies and of cognitive abilities have both been intensely studied. Yet little attention has been given to the question of how these two aspects may relate to each other, as a result of their ...
Toward a mechanistic understanding of vulnerability to hook-and-line fishing : Boldness as the basic target of angling-induced selection Klefoth, Thomas; Skov, Christian; Kuparinen, Anna; Arlinghaus, Robert (Wiley-Blackwell Publishing, Inc., 2017)n passively operated fishing gear, boldness‐related behaviors should fundamentally affect the vulnerability of individual fish and thus be under fisheries selection. To test this hypothesis, we used juvenile common‐garden ...
Experimental size-selective harvesting affects behavioral types of a social fish Sbragaglia, Valerio; Alós, Josep; Fromm, Kim; Monk, Christopher T.; Díaz-Gil, Carlos; Uusi-Heikkilä, Silva; Honsey, Andrew E.; Wilson, Alexander D.M.; Arlinghaus, Robert (John Wiley & Sons Ltd., 2019)In most fisheries, larger fish experience substantially higher mortality than smaller fish. Body length, life-history and behavioral traits often correlate, such that fisheries-induced changes in size or life-history can ...
