Tolerable Levels of Nonclinical Vehicles and Formulations Used in Studies by Multiple Routes in Multiple Species With Notes on Methods to Improve Utility.
Gad SC, et al. Int J Toxicol 2016 - Review. PMID 26755718
Formulation of nonclinical evaluations is a challenge, with the fundamental need to achieve multiples of the clinical exposure complicated by differences in species and routes of administration-specific tolerances, depending on concentrations, volumes, dosing regimen, duration of each administration, and study duration. ...The results identified 108 single-component vehicles (and 305 combination formulations) used in more than 1,040 studies across multiple species (dog, primate, rat, mouse, rabbit, guinea pig, minipig, pig, chick embryo, and cat) by multiple routes for a wide range of study durations. ...

Species Concepts: What about Ticks?
Dantas-Torres F. Trends Parasitol 2018 - Review. PMID 30343986
In this article I address the issue of the species concept in tick taxonomy. While the typological species concept is still the most widely used, the biological and phylogenetic species concepts are growing in popularity among tick taxonomists. ...The adoption of an integrative species concept is discussed, in light of recent advances in our understanding of the genetics, morphology, and biology of ticks....

Assessing species saturation: conceptual and methodological challenges.
Olivares I, et al. Biol Rev Camb Philos Soc 2018 - Review. PMID 29733121
Is there a maximum number of species that can coexist? Intuitively, we assume an upper limit to the number of species in a given assemblage, or that a lineage can produce, but defining and testing this limit has proven problematic. ...We argue that assessing species saturation is possible, but that many studies conducted to date have conceptual and methodological flaws that prevent us from currently attaining a good idea of the occurrence of species saturation....

Constraints on Statistical Learning Across Species.
Santolin C and Saffran JR. Trends Cogn Sci 2018 - Review. PMID 29150414 Free PMC article.
In the current review we interpret cross-species research on statistical learning based on the perceptual and cognitive mechanisms that characterize the human and nonhuman models under investigation. ...

Species-specific diversification.
Stadler T. Nat Ecol Evol 2019. PMID 31160737
Phenotypic Plasticity and Species Coexistence.
Turcotte MM and Levine JM. Trends Ecol Evol 2016 - Review. PMID 27527257
Ecologists are increasingly interested in predicting how intraspecific variation and changing trait values impact species interactions and community composition. For many traits, much of this variation is caused by phenotypic plasticity, and thus the impact of plasticity on species coexistence deserves robust quantification. ...

The arrangement of lateral veins along the midvein of leaves is not related to leaf phyllotaxis
Koyama K and Masuda T. Sci Rep 2018. PMID 30401940 Free PMC article.
Positions of leaves along a stem usually adhere to a genetically determined, species-specific pattern known as a leaf phyllotaxis. ...We analyzed the venation of temperate dicotyledonous species from different taxonomic groups and chose 18 woody and 12 herbaceous species that have reticulated leaf venation. ...

Species limits, phylogeography and reproductive mode in the Metarhizium anisopliae complex.
Rehner SA and Kepler RM. J Invertebr Pathol 2017. PMID 28578154
An essential first step to elucidating the ecology and life histories of Metarhizium anisopliae-group species as entomopathogens, endophytes and soil-adapted fungi is the ability to define species limits and confidently infer a species phylogeny. ...Although no PARB species has yet been confirmed to produce a sexual state, we demonstrate the mutually exclusive incidence of the MAT1 and MAT2 mating type idiomorphs among individuals in all PARB species. ...
