Abstract:
Cultural evolution is partly driven by the strategies individuals use to learn behaviour from others. Previous experiments on strategic learning let groups of participants engage in repeated rounds of a learning task and analysed how choices are affected by individual payoffs and the choices of group members. While groups in such experiments are fixed, natural populations are dynamic, characterized by overlapping generations, frequent migrations and different levels of experience. We present a preregistered laboratory experiment with 237 mostly German participants including migration, differen

Abstract:
Humpback whale seasonal migrations, spanning greater than 6500 km of open ocean, demonstrate remarkable navigational precision despite following spatially and temporally distinct migration routes. Satellite-monitored radio tag-derived humpback whale migration tracks in both the South Atlantic and South Pacific include constant course segments of greater than 200 km, each spanning several days of continuous movement. The whales studied here maintain these directed movements, often with better than 1° precision, despite the effects of variable sea-surface currents. Such remarkable directional pr

Abstract Running title: Monarch alternative migration: We collected 434 adult monarchs and surveyed milkweeds for immature monarchs in southwest Michigan, USA in order to test the hypothesis that monarchs are temporally variable, sequential partial migrants rather than partial migrants that may be spatially separated. Adult size, wing wear, female egg counts, fat content and sequestered chemical defenses were measured in monarchs across an entire season from spring migrant arrival, through breeding, until autumn migrant departure.

Abstract:
Migration is a valuable life history strategy for many species because it enables individuals to exploit spatially and temporally variable resources. Globally, the prevalence of species’ migratory behavior is decreasing as individuals forgo migration to remain resident year-round, an effect hypothesized to result from anthropogenic changes to landscape dynamics. Efforts to conserve and restore migrations require an understanding of the ecological characteristics driving the behavioral tradeoff between migration and residence. We identified migratory and resident behaviors of 42 mule deer (Odoc

Abstract Citizen science data have already been used to effectively address questions regarding migration, a fundamental stage in the life history of birds. In this study, we use data from eBird and from 3 additional regional citizen science databases to describe the migration routes and timing of the red-footed falcon Falco vespertinus in the Mediterranean region across 8 years (2010–2017). We further examine the seasonal and yearly variation in migration patterns and explore sites used during the species migration.

Abstract. Lateral migration of meandering rivers poses erosional risks to human settlements, roads, and infrastructure in alluvial floodplains. While there is a large body of scientific literature on the dominant mechanisms driving river migration, it is still not possible to accurately predict river meander evolution over multiple years. This is in part because we do not fully understand the relative contribution of each mechanism and because deterministic mathematical models are not equipped to account for stochasticity in the system.

Longstanding theory predicts that strategic flexibility in when and how to use social information can help individuals make adaptive decisions, especially when environments are temporally or spatially variable. A short-term increase in reliance on social information under these conditions has been experimentally shown in primates, including humans, but whether this occurs in other taxa is unknown. We asked whether migration between spatially variable environments affected social information use with a large-scale cultural diffusion experiment with wild great tits (Parus major) in captivity, a

Abstract The migration of birds is a complex form of behavior, affected by many environmental factors, such as spatial and temporal variations in food availability, predators, temperature, winds, and breeding opportunities (Ens et al. 1994). Until recently, most optimization models of migration have dealt with isolated aspects like optimal migration speed (Alerstam 1979; Liechti 1995; Hedenstrom and Alerstam 1995) or optimal fuel loads (Weber et al. 1994).

Abstract:
Abstract A spatial and temporal framework is a prerequisite for analyzing migration and mobility behavior because these behaviors are defined by occupation of a set of locations in some temporal sequence and can only be recognized by keeping track of the locations of individuals over time. Investigations of migration and residential mobility have typically focused on one aspect of this spatial-temporal sequencing: the relocation events that move individuals from one place to an other. These are either migration events that involve the relocation of individuals between relatively distant commun

Abstract Electrochemical chloride extraction (ECE) is a process used to extract or remove chloride ions from chloride contaminated reinforced concrete elements. The extraction is accomplished by application of an electrical field between a temporary external anode and steel embedded in concrete. The electric field induces an ionic current in the concrete electrolyte, a portion of which is carried by the negatively charged chloride ions moving away from the embedded steel and towards the external anode. Once sufficient amount of chloride ions are extracted the surface of the concrete element is
