Abstract Groups of animals can perform highly coordinated collective behaviours that confer benefits to the participating individuals by facilitating social information exchange and protection from predators 1 . Some these characteristics could arise when groups operate at critical points between two structurally functionally different states, leading maximal responsiveness external stimuli effective propagation 2,3 It has been proposed animal constitute examples self-organized systems...
Responding towards the actions of others is one most important behavioural traits whenever animals same species interact. Mutual influences among interacting individuals may modulate social responsiveness seen and thus make it often difficult to study level individual variation in responsiveness. Here, open-loop biomimetic robots that provide standardized, non-interactive cues can be a useful tool. These are not affected by live animal's but assumed still represent valuable biologically...
Biomimetic Robots (BRs) are becoming more common in behavioral research and, if they accepted as conspecifics, allow for new forms of experimental manipulations social interactions. Nevertheless, it is often not clear which cues emanating from a BR actually used communicative signals and how species or populations with different sensory make-ups react to specific types BRs. We herein present results experiments using two livebearing fishes that differ their capabilities. In the South Mexico,...
Understanding the linkage between behavioral types and dispersal tendency has become a pressing issue in light of global change biological invasions. Here, we explore whether dispersing individuals exhibit that differ from those remaining source population. We investigated feral population guppies ( Poecilia reticulata ) undergoes yearly range shift cycle. Guppies are among most widespread invasive species world, but temperate regions these tropical fish can only survive winter-warm...
Collective behaviour is widely accepted to provide a variety of antipredator benefits. Acting collectively requires not only strong coordination among group members, but also the integration among-individual phenotypic variation. Therefore, groups composed more than one species offer unique opportunity look into evolution both mechanistic and functional aspects collective behaviour. Here, we present data on mixed-species fish shoals that perform dives. These repeated dives produce water...
ABSTRACT The thermal ecology of ectotherm animals has gained considerable attention in the face human-induced climate change. Particularly aquatic species, experimental assessment critical limits (CTmin and CTmax) may help to predict possible effects global warming on habitat suitability ultimately species survival. Here we present data two endemic endangered extremophile fish inhabiting a geothermally heated sulfur-rich spring system southern Mexico: sulfur molly (Poecilia sulphuraria)...
In many animal species, collective behaviours can be explained by a simple set of interaction rules. It is an intriguing question whether this generality at the level mechanism also translates into function. Assuming that behaviour provides antipredator benefits for partaking individuals, we ask same protection against different predators in general. We investigated sulphur-adapted fishes their natural habitats Mexico. Here, fish schools are frequently attacked bird species and respond with...
Bird predation poses a strong selection pressure on fish. Since birds must enter the water to catch fish, combination of visual and mechano-acoustic cues (multimodal) characterize an immediate attack, while single (unimodal) may represent less dangerous disturbances. We investigated whether fish could use this information distinguish between non-threatening events adjust their antipredator response perceived level risk. To do so, we behavior sulphur molly (Poecilia sulphuraria), small...
Body size is often assumed to determine how successful an individual can lead others with larger individuals being better leaders than smaller ones. But even if are more readily followed, body correlates specific behavioral patterns and it thus unclear whether followed ones because of their or they behave in a certain way. To control for differences among differentially-sized leaders, we used biomimetic robotic fish (Robofish) different sizes. Live guppies (Poecilia reticulata) known...
Animals often face changing environments, and behavioral flexibility allows them to rapidly adaptively respond abiotic factors that vary more or less regularly. However, affect prey species do not necessarily their predators. Still, the prey’s response might predator indirectly, yet evidence from wild for such a classical bottom-up effect of shaping several trophic levels remains sparse. In many aquatic daily changes in oxygen concentrations occur frequently. When drop hypoxic levels, fishes...
Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive form proliferating populations beyond their native ranges. In Germany, convict cichlids ( Amatitlania nigrofasciata ) tilapia Oreochromis sp.) have established in the Gillbach, a small stream that receives warm water discharge from local power plant. Here, we report on discovery spotted Pelmatolapia mariae first record reproducing population this Europe. It...
Animals often show high consistency in their social organisation despite facing changing environmental conditions. Especially shoaling fish, fission–fusion dynamics that describe for which periods individuals are solitary or have been found to remain unaltered even when density changed. This compensatory ability is assumed be an adaptation towards constant predation pressure, but the mechanism through can actively compensate changes yet unknown. The aim of current study identify behavioural...
Abstract The ability of an individual to predict the outcome actions others and change their own behavior adaptively is called anticipation. There are many examples from mammalian species—including humans—that show anticipatory abilities in a social context, however, it not clear what extent fishes can anticipate interaction partners or underlying mechanisms for that To answer these questions, we let live guppies ( Poecilia reticulata ) interact repeatedly with open-loop (noninteractive)...
Electronic decision-support tools are becoming an essential component of government strategies to tackle non-native species invasions. This study describes the development and application a multilingual electronic tool for screening terrestrial animals under current future climate conditions: Terrestrial Animal Species Invasiveness Screening Kit (TAS-ISK). As adaptation widely employed Aquatic (AS-ISK), TAS-ISK question template inherits from original Weed Risk Assessment (WRA) related...
Abstract Feral populations of tropical fish species in temperate climates like Central Europe are a rare but repeatedly observed phenomenon. Due to the influence industrial or geothermal heated water, released may be able survive harsh winter conditions. Here we characterize newly discovered thermally polluted river, with an established population guppy ( Poecilia reticulata ) co-occurring native species. Through mark-recapture approach, estimated size guppies close warm water inflow around...

Abstract Body size is often assumed to determine how successful an individual can lead others with larger individuals being more likely than smaller ones. However, direct evidence for such a relation scarce. Furthermore, even if are lead, body correlates specific behavioral patterns (e.g., swimming capacity) and it thus unclear whether followed ones because they or behave in certain way. To control differences among differentially-sized leaders, we used biomimetic robotic fish – Robofish of...
