Voltinism and Laboratory Rearing of \u3ci\u3eMicrovelia Hinei\u3c/i\u3e (Heteroptera: Gerromorpha: Veliidae) [PDF]

open access: yes, 2018
Voltinism in Microvelia hinei was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as adults, which became active in late April; adults were last collected in late September. First instars were found from mid-May to

Skin hydrophobicity as an adaptation for self‐cleaning in geckos

open access: yesEcology and Evolution, Volume 10, Issue 11, Page 4640-4651, June 2020., 2020
Hydrophobicity is common in plants and animals, but ecological factors promoting its evolution are still unclear. Using advancing contact‐angle measurements, we test that high hydrophobicity has coevolved with terrestrial microhabitat use in geckos, as ground is dirty and filled with pathogens. Our results suggest that hydrophobicity has coevolved with

Dr. J. E. McPherson, Educator and Researcher Extraordinaire: Biographical Sketch and List of Publications [PDF]

open access: yes, 2018
(excerpt) Like many outstanding naturalists, John E. (“Jay”) McPherson grew up with a strong interest in the natural world, especially insects. This innate curiosity led him to enroll as a zoology major at San Diego State University in 1959.

Sex on the Beach: Sexual Size Dimorphism Among Aquatic Bugs (Nepomorpha) Inhabiting Different Habitats [PDF]

open access: yesEcol Evol
We examined the degree of sexual size dimorphism (SSD), based on body length, in approximately 45% of known water bug (Nepomorpha) species. Contrary to our initial hypothesis, we found that females are not significantly longer than males in most species. Our research revealed that habitat plays a significant role in SSD.

Life History of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Hemiptera: Mesoveliidae) in Southern Illinois [PDF]

open access: yes, 2017
The life history of Mesovelia mulsanti was studied during 1983-1986. This species was apparently trivoltine with a partial 4th generation at the end of the year. It overwintered as eggs. First ins tars appeared in mid-April followed by marked overlapping
