Climate, Physiology, and Distributions: The Role of Thermal Physiology in Biological Invasions [PDF]

open access: yes, 2023
Climate is a primary factor influencing species range dynamics, particularly for ectotherms whose body temperature is closely tied to the surrounding conditions.

Blue reflectance in tarantulas is evolutionarily conserved despite nanostructural diversity [PDF]

open access: yes, 2015
Slight shifts in arrangement within biological photonic nanostructures can produce large color differences, and sexual selection often leads to high color diversity in clades with structural colors. We use phylogenetic reconstruction, electron microscopy,

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Better a Broader Diagnosis Than a Misdiagnosis: The Study of a Neoplastic Condition in a Male Individual who Died in Early 20th Century (Coimbra, Portugal) [PDF]

open access: yes, 2013
The paleopathological record of neoplastic conditions in the past is considered scarce. The detection of tumours in ancient populations is hindered by the quality and quantity of signs visible on the skeleton, the methodological approach, the ...

Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces

open access: yesScience Education, EarlyView.
ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Plant strategies, dispersal and origins of flora at the northern Coral Sea Islands Territory, Australia [PDF]

open access: yes, 2013
A checklist of vascular plants of Coringa-Herald National Nature Reserve (CHNNR) (17º 11’S, 149º 00’ E to 16º 23’S, 150º 30’E and Willis Island (16º 24’S, 149º 58’E) at the northern Coral Sea Islands Territory of Australia compiled during 2006/07 surveys,

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...
