In Britain, Hesperia comma inhabits heavily grazed calcareous grasslands. When rabbits were killed by myxomatosis in the mid-1950s, this habitat became overgrown and H. declined to 46 or fewer localities 10 refuge regions (Thomas et al. 1986). By 1982, had recovered many former sites again appeared suitable, but not been recolonized. Between 1982 1991, number of patches that populated increased 30% South North Downs. Most increase was East Sussex. The probability colonization between 1991...
The mechanisms underpinning the ecological impacts of presence artificial night lighting remain elusive. One suspected underlying cause is that light at (LAN) supresses nocturnal production melatonin, a key driver biological rhythm and potent antioxidant with proposed role in immune function. Here, we briefly review evidence for melatonin as link between LAN changes behaviour physiology. We then present preliminary data supporting potential to act recovery agent mitigating negative effects...
Abstract Invertebrates comprise the most diversified animal group on Earth. Due to their long evolutionary history and small size, invertebrates occupy a remarkable range of ecological niches, play an important role as “ecosystem engineers” by structuring networks mutualistic antagonistic interactions in almost all terrestrial ecosystems. Urban forests provide critical ecosystem services humans, and, other systems, are central maintaining functioning urban forests. Identifying can help...
Models of age-related mate choice predict female preference for older males as they have proven survival ability. However, these models rarely address differences in sperm age and male mating history when evaluating the potential benefits to females from partners. We used a novel experimental design assess simultaneously relative importance three parameters hide beetle, Dermestes maculatus. In two-part experiment we first explored success subsequently examined consequences age, on fecundity...
Women continue to be under-represented in the sciences, with their representation declining at each progressive academic level. These differences persist despite long-running policies ameliorate gender inequity. We compared exposure and visibility an evolutionary biology conference for attendees two different levels: student post-PhD academic. Despite there being almost exactly a 1:1 ratio of women men attending conference, we found that when considering only those who presented talks, spoke...
Light represents one of the most reliable environmental cues in biological world. In this review we focus on evolutionary consequences to changes organismal photic environments, with a specific class Insecta. Particular emphasis is placed transitional forms that can be used track evolution from (1) diurnal nocturnal (dim-light) or (2) surface subterranean (aphotic) as well (3) ecological encroachment anthropomorphic light habitats (artificial at night). We explore influence environment an...
Most theoretical models of age–related mate choice predict that females should prefer older males because they have proven survival ability. An alternative view is represent inferior mates negative genetic correlations between early and late fitness components, or traded off longevity against other accumulated deleterious germ–line mutations, are less well adapted to current conditions than more recently born individuals. While numerous studies reported female for males, few explicitly...
Diet is arguably the most significant environmental factor shaping chemical signals in animals. In rare cases, dietary components are converted directly into pheromones or signature mixtures but more generally variation an individual's diet influences their overall condition and thus capacity to synthesise signal. Typically, variable between individuals of same species this can lead signals. This presents specific challenges receivers, who must be able recognise respond a greater range...
Abstract Humans are lighting the night‐time environment with ever increasing extent and intensity, resulting in a variety of negative ecological effects individuals populations. Effects light at night on reproductive fitness traits demonstrated across taxa however, mechanisms underlying these largely untested. One possible mechanism is that may result perturbed reactive oxygen species (ROS) oxidative stress levels. Here, we reared Drosophila melanogaster under either dim (10 lx) or no (0 for...
Abstract The reach of artificial light at night (ALAN) is growing rapidly around the globe, including increasing use energy‐efficient LED lights. Many studies document physiological costs night, but far fewer have focused on potential benefits for nocturnal insectivores and likely ecological consequences shifts in predator–prey relationships. We investigated effects ALAN foraging behaviour prey capture success juvenile Australian garden orb‐web spiders ( Eriophora biapicata ). Laboratory...
We experimentally investigated the fitness consequences of female mate choice in order to test relative importance three competing but non–exclusive hypotheses for maintenance pronounced mating preferences on leks: that females benefit directly; they gain indirect Fisherian benefits by producing more attractive sons; or indirectly because preferred males possess 'good genes' confer increased viability their sons and daughters. allowed lekking sandflies, Lutzomyia longipalpis, choose between...
Exposure to constant light has a range of negative effects on behaviour and physiology, including reduced immune function in both vertebrates invertebrates. It is proposed that the associated suppression melatonin (a ubiquitous hormone powerful antioxidant) response presence at night could be an underlying mechanistic link driving changes function. Here, we investigated relationship between illumination, function, using model invertebrate species, Australian black field cricket, Teleogryllus...
The prevalence of artificial light at night (ALAN) is increasing rapidly around the world. potential physiological costs this lighting are often evident in life history shifts. We investigated effects chronic night-time exposure to ecologically relevant levels LED on traits nocturnal Australian garden orb-web spider (Eriophora biapicata). reared spiders under a 12-h day and either natural darkness (∼0 lux) or dim (∼20 assessed juvenile development, growth mortality, adult reproductive...
Artificial light at night could have widespread and detrimental impacts on sleep. To reduce disruptive effects of artificial sleep in humans, most smartphones computers now software that reduces blue emissions night. Little is known about whether reducing from city lights also benefit urban wildlife. We investigated the blue-rich (white) blue-reduced (amber) LED streetlights accelerometry-defined rest, electrophysiologically-identified sleep, plasma melatonin a diurnal bird, black swan...
