Threats to cycad biocultural heritage in the Amami Islands, Japan

open access: yesPlant Species Biology, EarlyView.
The central point we seek to frame in this article is that the increasing infestations of cycad aulacaspis scale in the Amami guntō existentially threaten not only the islands' sotetsu but rather entire cultural systems and natural ecologies that have developed around these plants.

THE COSMOPOLITICS OF CATS AND WILDLIFE ON CAPE TOWN'S URBAN EDGE

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Free‐ranging cats are widely tolerated in cities, and animal welfare organizations increasingly allow for ‘trap, neuter and release’ (TNR) of unowned cats. We show, using the example of a university campus adjacent to a national park in a large metropole, that this has implications for cosmopolitics over biodiversity on the urban edge.

Bluer in the city: urban male lizards exhibit more intense sexual coloration and lower parasite loads than non‐urban males

open access: yesIntegrative Zoology, EarlyView.
The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs

open access: yesIntegrative Zoology, EarlyView.
Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but
