“…Reasons to do so probably include the search for empty territories or for suitable places to spend the dry season, among others. Terrestrial displacements were already reported for other freshwater turtles, such as the chelid Chelodina longicollis (Roe and Georges 2008;Rees et al 2009), and the emydids Trachemys scripta (Gibbons et al 1990), Emydoidea blandingii (Ross and Anderson 1990), and Clemmys guttata (Haxton and Berrill 2001). Presumably, most freshwater turtles have the skill to migrate across land, and effectively do it when resources become meager in their original aquatic habitats (Kramer 1995;Milan and Melvin 2001).…”

Distribution patterns of most of the 20 Neotropical freshwater turtles belonging to the family Chelidae are usually based on few locality records. We here report on vouchered records of three species of the chelid genus Mesoclemmys in the Brazilian state of Mato Grosso. Presence of M. vanderhaegei is confirmed for the Amazon River Basin, and M. gibba and M. raniceps are recorded in Mato Grosso for the first time.

“…Urban ecology is an established field of research: ecologists have long shown the impact of urbanization on population and community dynamics [2], and in the last two decades new interest has been arising around the mechanisms of individuals' response to urbanization [3], e.g. stress and reproductive physiology [4,5], temporal and spatial activity patterns [6], metabolism [7] and behaviour [8]. Moreover, while the effects of noise at the community and individual level have started to be elucidated [9,10], knowledge about the ecological and evolutionary consequences of artificial night lighting is still limited (but see [11]).…”

Artificial light at night advances avian reproductive physiology

Artificial light at night is a rapidly increasing phenomenon and it is presumed to have global implications. Light at night has been associated with health problems in humans as a consequence of altered biological rhythms. Effects on wild animals have been less investigated, but light at night has often been assumed to affect seasonal cycles of urban dwellers. Using light loggers attached to free-living European blackbirds (Turdus merula), we first measured light intensity at night which forest and city birds are subjected to in the wild. Then we used these measurements to test for the effect of light at night on timing of reproductive physiology. Captive city and forest blackbirds were exposed to either dark nights or very low light intensities at night (0.3 lux). Birds exposed to light at night developed their reproductive system up to one month earlier, and also moulted earlier, than birds kept under dark nights. Furthermore, city birds responded differently than forest individuals to the light at night treatment, suggesting that urbanization can alter the physiological phenotype of songbirds. Our results emphasize the impact of human-induced lighting on the ecology of millions of animals living in cities and call for an understanding of the fitness consequences of light pollution.

“…In California, urban gardens in the summer dry months (with <1 cm precipitation per month much in the form of fog) may provide an important irrigated habitat in comparison to the surrounding urban matrix. Indeed, supplemental irrigation in cities maintains and supports biodiversity during drought events [9,81,82], as California experienced during the time of this study. Michigan has an opposite precipitation pattern with relatively wet summers, receiving on average 8 to 9 cm/month in the summer [83].…”

Abstract:Urban agroecosystems offer an opportunity to investigate the diversity and distribution of organisms that are conserved in city landscapes. This information is not only important for conservation efforts, but also has important implications for sustainable agricultural practices. Associated biodiversity can provide ecosystem services like pollination and pest control, but because organisms may respond differently to the unique environmental filters of specific urban landscapes, it is valuable to compare regions that have different abiotic conditions and urbanization histories. In this study, we compared the abundance and diversity of ladybird beetles within urban gardens in California and Michigan, USA. We asked what species are shared, and what species are unique to urban regions. Moreover, we asked how beetle diversity is influenced by the amount and rate of urbanization surrounding sampled urban gardens. We found that the abundance and diversity of beetles, particularly of unique species, respond in opposite directions to urbanization: ladybirds increased with urbanization in California, but decreased with urbanization in Michigan. We propose that in California water availability in gardens and the urbanization history of the landscape could explain the divergent pattern. Thus, urban context is likely a key contributor to biodiversity within habitats and an important consideration for sustainable agricultural practices in urban agroecosystems.
