Temporal tracking of mineralization and transcriptional developments of shell formation during the early life history of pearl oyster Pinctada maxima [PDF]

open access: yes, 2011
Molluscan larval ontogeny is a highly conserved process comprising three principal developmental stages. A characteristic unique to each of these stages is shell design, termed prodissoconch I, prodissoconch II and dissoconch.

European eel (Anguilla anguilla): prediction of spawner escapement from continental population parameters [PDF]

open access: yes, 2000
This paper describes the assessment of silver European eel (Anguilla anguilla) escapement based on a “sedentary” population fraction analysis in a 60-km2 watershed of northern Brittany (France).

Visualization of insect metamorphosis

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2019
Metamorphosis and, in particular, holometaboly, the development of organisms through a series of discrete stages (egg, larva, pupa, adult) that hardly resemble one another but are finely adapted to specific roles in the life cycle of the organism, has ...

Emerging Issues for Counselors Applying Neuroscience With Black Clients: Avoiding Scientific Racism

open access: yesJournal of Multicultural Counseling and Development, EarlyView.
ABSTRACT Neuroscience‐infused methods are heavily impacting the manner in which counselors, educators, and researchers approach working with clients and conducting research. While some scholars perceive neuroscience as scientifically objective and culturally neutral, that is not entirely true.

Microarray analysis of a salamander hopeful monster reveals transcriptional signatures of paedomorphic brain development

open access: yesBMC Evolutionary Biology, 2010
Background The Mexican axolotl (Ambystoma mexicanum) is considered a hopeful monster because it exhibits an adaptive and derived mode of development - paedomorphosis - that has evolved rapidly and independently among tiger salamanders.

Up and away: ontogenic transference as a pathway for aerial dispersal of microplastics [PDF]

open access: yes, 2018
Microplastics (MPs) are ubiquitous pollutants found in marine, freshwater and terrestrial ecosystems. With so many MPs in aquatic systems it is inevitable that they will be ingested by aquatic organisms, and be transferred up through the food chain ...

Road mortality alters the body size and age structure of amphibians

open access: yesOikos, EarlyView.
Road mortality affects a wide range of animal species, including amphibians. Worldwide, many amphibian species, including the Asiatic toad Bufo gargarizans, are impacted by road mortality, but the ecological consequences remain poorly understood. This study aimed to evaluate how road mortality influences population traits by comparing body sizes and ...

Optical coherence tomography:age estimation of Calliphora vicina pupae in vivo? [PDF]

open access: yes, 2014
Necrophagous blowfly pupae are valuable contributors to the estimation of post-mortem interval, should an accurate age estimate be obtained. At present, this is reliant on a combination of rearing and destructive methods conducted on preserved samples ...

Immunization of cattle with a Rhipicephalus microplus chitinase peptide containing predicted B-cell epitopes reduces tick biological fitness

open access: yesParasitology
Abstract Rhipicephalus microplus, the cattle fever tick, is the most important ectoparasite impacting the livestock industry worldwide. Overreliance on chemical treatments for tick control has led to the emergence of acaricide-resistant ticks and ...

Plant and insect functional traits influence herbivore performance under climate change

open access: yesOikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...
