I am an NSF Postdoctoral Researcher at Washington University in St Louis and UC Berkeley where I am working on the ecology and evolution of urban Eastern Gray Squirrels. You can find out more about me on my personal site www.elizabethcarlen.com

New Lit Alert: Signs of Urban Evolution? Morpho-Functional Traits Co-variation Along a Nature-Urban Gradient in a Chagas Disease Vector

Signs of Urban Evolution? Morpho-Functional Traits Co-variation Along a Nature-Urban Gradient in a Chagas Disease Vector Ana C. Montes de Oca-Aguilar, Adriana González-Martínez, Raúl Chan-González, Pilar Ibarra-López, Selene Smith-Ávila, Alex Córdoba-Aguilar, and Carlos N. Ibarra-Cerdeña Abstract Environmental change (i.e., urbanization) impacts species in contrasting ways, with some species experiencing benefits given their way of life... Continue Reading →

New Lit Alert: Carnivore Niche Partitioning in a Human Landscape

Carnivore Niche Partitioning in a Human Landscape Mauriel Rodriguez Curras, Emiliano Donadio, Arthur D. Middleton, and Jonathan N. Pauli Abstract To minimize competitive overlap, carnivores modify one of their critical niche axes: space, time, or resources. However, we currently lack rules for how carnivore communities operate in human-dominated landscapes. We simultaneously quantified overlap in the... Continue Reading →

New Lit Alert: Socio-ecological drivers of multiple zoonotic hazards in highly urbanized cities

Socio-ecological drivers of multiple zoonotic hazards in highly urbanized cities Matthew A. Combs, Pallavi A. Kache, Meredith C. VanAcker, Nichar Gregory, Laura D. Plimpton, Danielle M. Tufts, Maria P. Fernandez, Maria A. Diuk-Wasser Abstract The ongoing COVID-19 pandemic is a stark reminder of the devastating consequences of pathogen spillover from wildlife to human hosts, particularly... Continue Reading →

New Lit Alert: Cat colonies and flight initiation distances of urban birds: Dealing with conflicting sources of citizen wellbeing

Cat colonies and flight initiation distances of urban birds: Dealing with conflicting sources of citizen wellbeing Mario Díaz, Jonatan Fernández, Alicia Page Abstract Feral cat colonies in cities improve the wellbeing of people who feed and care for them, but they can have negative effects on biodiversity due to the predatory behaviour of cats. We... Continue Reading →

New Lit Alert: Connectivity in the Urban Landscape (2015–2020): Who? Where? What? When? Why? and How?

Connectivity in the Urban Landscape (2015–2020): Who? Where? What? When? Why? and How? Todd R. Lookingbill, Emily S. Minor, Charles S. Mullis, Gabriela C. Nunez-Mir & Philip Johnson Abstract Purpose of Review This review uses a combination of narrative and systematic review techniques, including automated content analysis (ACA), to summarize the last 5 years of research...

New Lit Alert: Variation in hematological indices, oxidative stress, and immune function among male Song Sparrows from rural and low-density urban habitats

Variation in Hematological Indices, Oxidative Stress, and Immune Function Among Male Song Sparrows From Rural and Low-Density Urban Habitats Christopher G. Goodchild, Isaac VanDiest, Samuel J. Lane, Michelle Beck, Hallum Ewbank and Kendra B. Sewall Abstract A central theme in the field of ecology is understanding how environmental variables influence a species’ distribution. In the last...

New Lit Alert: Detecting patterns of vertebrate biodiversity across the multidimensional urban landscape

Detecting patterns of vertebrate biodiversity across the multidimensional urban landscape Marina Alberti & Tianzhe Wang Abstract Explicit characterisation of the complexity of urban landscapes is critical for understanding patterns of biodiversity and for detecting the underlying social and ecological processes that shape them. Urban environments exhibit variable heterogeneity and connectivity, influenced by different historical contingencies,... Continue Reading →

New Lit Alert: Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal

Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal Juan Carlos Senar & Mats Björklund Abstract Rates of phenotypic change are greater in cities than in any other habitat. Consequently, urban habitats are an ideal experimental area to study contemporary evolution and adaptation. A key question... Continue Reading →

New Lit Alert: Bioindicator snake shows genomic signatures of natural and anthropogenic barriers to gene flow

Bioindicator snake shows genomic signatures of natural and anthropogenic barriers to gene flow Damian C. Lettoof, Vicki A. Thomson, Jari Cornelis, Philip W. Bateman, Fabien Aubret, Marthe M. Gagnon, and Brenton von Takach Abstract Urbanisation alters landscapes, introduces wildlife to novel stressors, and fragments habitats into remnant ‘islands’. Within these islands, isolated wildlife populations can... Continue Reading →

New Lit Alert: Phenotypic variation in urban environments: mechanisms and implications

Phenotypic variation in urban environments: mechanisms and implications M.J. Thompson, P. Capilla-Lasheras, D.M. Dominoni, D. Réale, & A. Charmantier Abstract In the past decade, numerous studies have explored how urbanisation affects the mean phenotypes of populations, but it remains unknown how urbanisation impacts phenotypic variation, a key target of selection that shapes, and is shaped...

New Lit Alert: Genetic differentiation in pesticide resistance between urban and rural populations of a nontarget freshwater keystone interactor, Daphnia magna

Genetic differentiation in pesticide resistance between urban and rural populations of a nontarget freshwater keystone interactor, Daphnia magna Kristien I. Brans, Rafaela A. Almeida, Maxime Fajgenblat Abstract There is growing evidence that urbanization drives adaptive evolution in response to thermal gradients. One such example is documented in the water flea Daphnia magna. However, organisms residing in urban lentic... Continue Reading →
