Data from: Research culture: a survey of travel behaviour among scientists in Germany and the potential for change
Awareness of the environmental impact of conferences is growing within the scientific community. Here we report the results of a survey in which scientists in Germany were asked about their attendance at conferences, their reasons for attending, and their willingness to explore new approaches that would reduce the impact of conferences on the environment. A majority of respondents were keen to reduce their own carbon footprint and were willing to explore alternatives to the traditional conference.
Data from: Characterising bird-keeping user-groups on Java reveals distinct behaviours, profiles and potential for change
<p>1. Over 70 million cage-birds are kept across 12 million households on the island of Java, Indonesia, fuelling serious concerns for the health of regional wild bird populations. Understanding the behaviours, preferences and demographic profiles of bird-keepers will guide attempts to reduce demand for wild birds and hence the impact of trade on wild populations and their host ecosystems.</p> <p>2. We profile three songbird-keeping user-groups based on interviews of nearly one thousand people across Java: Hobbyists, who own birds primarily as pets; Contestants, who own birds to enter in singing contests; and Breeders, who own birds to breed and train for resale or as a pastime.</p> <p>3. User-groups diverged in their bird-keeping habits and preferences. Hobbyists tended to own small numbers of inexpensive and typically native birds, while contestants and breeders owned larger numbers of often valuable birds. Hobbyists were far less likely to consider origin when buying a bird, owned a larger proportion of both potentially wild-caught and globally threatened birds, but showed no preference for any taxon. By contrast, owning relatively large numbers of lovebirds (Agapornis spp.) and Zebra Doves (Geopelia striata) were key characteristics of contestants, while breeders owned the largest number of birds and species, in particular White-rumped Shamas (Kittacincla malabarica). Within a two-year period, user-group membership was fluid, with much transitioning between non-bird ownership and hobbyists, recruitment of non-bird owners to contestants, and movement both in and out of the breeder group.</p> <p>4. Our study provides behavioural change efforts with demographic and geographic profiles to target bird-keepers, who tended to be more affluent, urban and live in the eastern provinces. Among bird-keepers, hobbyists tended to be middle-aged and live in the western provinces, contestants were younger urban bird-keepers employed in business, and breeders were commoner in the eastern provinces, reflecting the cultural importance of bird-keeping among the Javanese.</p> <p>5. Efforts to increase the sustainability of bird-keeping in Java should focus on emphasising the importance of captive-bred birds, in particular to hobbyists, the largest user-group, whose bird-keeping behaviour poses the biggest threat to wild bird populations, whilst also incentivising legitimate breeding enterprises among contestants and breeders.</p>
Data from: Behavioural responses of Atlantic cod to sea temperature changes
Understanding responses of marine species to temperature variability is essential to predict impacts of future climate change in the oceans. Most ectotherms are expected to adjust their behavior to avoid extreme temperatures and minimize acute changes in body temperature. However, measuring such behavioral plasticity in the wild is challenging. Combining 4 years of telemetry-derived behavioral data on juvenile and adult (30–80 cm) Atlantic cod (Gadus morhua), and in situ ocean temperature measurements, we found a significant effect of sea temperature on cod depth use and activity level in coastal Skagerrak. During summer, cod were found in deeper waters when sea surface temperature increased. Further, this effect of temperature was stronger on larger cod. Diel vertical migration, which consists in a nighttime rise to shallow feeding habitats, was stronger among smaller cod. As surface temperature increased beyond ~15°C, their vertical migration was limited to deeper waters. In addition to larger diel vertical migrations, smaller cod were more active and travelled larger distances compared to larger specimens. Cold temperatures during winter tended, however, to reduce the magnitude of diel vertical migrations, as well as the activity level and distance moved by those smaller individuals. Our findings suggest that future and ongoing rises in sea surface temperature may increasingly deprive cod in this region from shallow feeding areas during summer, which may be detrimental for local populations of the species.
Data from: Infection-induced behavioural changes reduce connectivity and the potential for disease spread in wild mice contact networks
Infection may modify the behaviour of the host and of its conspecifics in a group, potentially altering social connectivity. Because many infectious diseases are transmitted through social contact, social connectivity changes can impact transmission dynamics. Previous approaches to understanding disease transmission dynamics in wild populations were limited in their ability to disentangle different factors that determine the outcome of disease outbreaks. Here we ask how social connectivity is affected by infection and how this relationship impacts disease transmission dynamics. We experimentally manipulated disease status of wild house mice using an immune challenge and monitored social interactions within this free-living population before and after manipulation using automated tracking. The immune-challenged animals showed reduced connectivity to their social groups, which happened as a function of their own behaviour, rather than through conspecific avoidance. We incorporated these disease-induced changes of social connectivity among individuals into models of disease outbreaks over the empirically-derived networks. The models revealed that changes in host behaviour frequently resulted in the disease being contained to very few animals, as opposed to becoming widespread. Our results highlight the importance of considering the role that behavioural alterations during infection can have on social dynamics when evaluating the potential for disease outbreaks.
Data from: Rival group scent induces changes in dwarf mongoose immediate behaviour and subsequent movement
In many social species, groups of animals defend a shared territory against rival conspecifics. Intruders can be detected from a variety of cues, including fecal deposits, and the strength of response is expected to vary depending on the identity of the rival group. Previous studies examining differences in response to neighbor and stranger groups have focused on the immediate response to the relevant cues. Here, we investigated how simulated intrusions of rival groups affect both immediate responses and postinspection movement patterns. To do so, we used a fecal translocation experiment at latrine sites within the territories of dwarf mongoose Helogale parvula groups. Immediate responses were adjusted to the level of threat, with greater scent-marking behavior, time spent at the latrine, and group-member participation when groups were presented with fecal matter from out-group rivals relative to control (own group and herbivore) feces. Subsequent movement of the group was also affected by threat level, with a decrease in speed and distance covered following simulated intrusions by out-group rivals compared with control conditions. However, there were no significant differences in immediate responses or post-latrine movement patterns when comparing simulated neighbor and stranger intrusions. These results indicate that territorial intrusions can elicit not just an immediate change in behavior but more far-reaching consequences in terms of movement dynamics. They also raise the possibility that neighbor–stranger discrimination predictions are not necessarily as clear-cut as previously described.
Data from: Study on the foraging behaviour of the European nightjar Caprimulgus europaeus reveals the need for a change in conservation strategy in Belgium
Effective nature conservation requires coherent actions based on the best available evidence concerning protected species. Recent studies have suggested that European nightjars Caprimulgus europaeus forage outside their recognized breeding habitats, yet, for Flanders (northern Belgium) information on nightjar foraging behaviour and key foraging habitats is lacking. To assess whether the foraging ecology of nightjars in Flanders is similar to that observed in other parts of Europe, we studied the crepuscular behaviour of this species in Bosland (northeastern Flanders) during a five-year radio telemetry study. Tracking of 48 individuals within a coniferous forest was standardized and home ranges were calculated using a kernel density estimator (fixed kernel). Habitat use was investigated by comparing kernel placement to available habitat. Average maximal foraging distance was 2603 ± 1094 m and home ranges extended up to 691 ha. We identified the key foraging habitats to be extensively-cultivated grasslands and recreational areas, areas that were previously assumed unsuitable for Belgian nightjars. Our results indicate the importance of foraging sites outside the breeding territory, confirming the findings of previous studies performed elsewhere in Europe. Incorporating our findings into future conservation plans could, therefore, lead to improved efficiency of EU conservation measures, designed for the protection of this bird species in Flanders.
Microevolutionary change in mimicry? Erosion of rattling behaviour among nonvenomous snakes on islands lacking rattlesnakes
Batesian mimics––harmless species that converge on the warning signals of a dangerous species––are spectacular examples of adaptation, but few documented cases involve acoustic signals. Even fewer studies have documented microevolutionary change in mimicry of any kind. Here, we describe potential evolutionary change in acoustic mimicry. Many nonvenomous snakes vibrate their tail tip when threatened, making a sound resembling a venomous rattlesnake. When we compared this behaviour between gopher snakes from mainland California where rattlesnakes are present versus nearby derived island populations where rattlesnakes are absent, we found that island snakes vibrated their tail for a shorter duration. Thus, defensive tail vibration may be acoustic mimicry of rattlesnakes that is undergoing erosion in an area lacking rattlesnakes, providing evidence of possible microevolutionary change in mimicry.
