Is Plastic Always Fantastic? Selection on Thermal Plasticity in Urban Anoles

a lizard clinging to a metal fence

A recent publication in Nature Communications goes above and beyond in studying how selection on adaptive and/or maladaptive gene expression plasticity may be regulating thermal tolerance in urban anoles. The importance of plasticity in the colonization of new environments is a widely-accepted argument, however, the role of plasticity in facilitating adaptive evolution remains controversial. Plasticity... Continue Reading →

New Lit Alert: Urbanization extends flight phenology and leads to local adaptation of seasonal plasticity in Lepidoptera

Urbanization extends flight phenology and leads to local adaptation of seasonal plasticity in Lepidoptera Thomas Merckx, Matthew E. Nielsen, Janne Heliölä, Mikko Kuussaari, Lars B. Pettersson, Juha Pöyry, Juha Tiainen, Karl Gotthard, and Sami M. Kivelä Abstract Urbanization is gaining force globally, which challenges biodiversity, and it has recently also emerged as an agent of... Continue Reading →

New Lit Abstract: De Novo Transcriptome Analysis Reveals Potential Thermal Adaptation Mechanisms in the Cicada Hyalessa fuscata

De Novo Transcriptome Analysis Reveals Potential Thermal Adaptation Mechanisms in the Cicada Hyalessa fuscata Hoa Quynh Nguyen, Yuseob Kim, and Yikweon Jang Abstract In metropolitan Seoul, populations of the cicada Hyalessa fuscata in hotter urban heat islands (“high UHIs”) exhibit higher thermal tolerance than those in cooler UHIs (“low UHIs”). We hypothesized that heat stress... Continue Reading →

Urban Observation of the Week: Chillin’ Frog

It's hot out there! This summer has seen excessive heat waves sweeping the world and breaking records - many places recorded the hottest summer temperatures ever! What does an ectotherm do to chill out in this extreme heat? This frog has found an unusual solution and is our urban observation of the week. https://www.instagram.com/p/B0HrHVlBgHN/?igshid=pb6g3al3s2g Do... Continue Reading →

Time for a Dive Part I: An Introduction to the Water Flea Daphnia magna and Urban Aquatic Habitats

Above: (c) Erin Walsh for Journal of Conservation Physiology on the evolution of heat tolerance in Daphnia “No they do not itch”, “Yes, they are super cute”, and “Yes, they live in water”. “Also in this pond?”. Behold the standard answers given during an ‘interrogatory’ conversation with a passer-by on a sunny sampling day, somewhere in... Continue Reading →
