The identification of Anopheles (Nyssorhynchus) rondoni (Diptera: Culicidae) in Mato Grosso, Brazil: an analysis of key character variability

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
A morphological study was made of a population of Anopheles (Nyssorhynchus) rondoni (Neiva and Pinto) from northern Mato Grosso, Brazil. This population usually lacked the primary key character of a dark basal band on hindtarsomere 3, i.e., hindtarsomere

Persistent pods of the tree Acacia caven: a natural refuge for diverse insects including Bruchid beetles and the parasitoids Trichogrammatidae, Pteromalidae and Eulophidae [PDF]

open access: yesJournal of Insect Science, 8 (12/06/2006) 1-9 pages, 2007
The persistent pods of the tree, Acacia caven, that do not fall from the tree provide opportunities for the appearance of a diverse group of insects the following season. Such pods collected during the spring of 1999 in Chile were indehiscent with highly sclerified pod walls.

WEIGHT CHANGE OF DIAPAUSING OR DEVELOPING PUPA IN SAMIA CYNTHIA PRYERI [PDF]

open access: yes, 1990
Weight of the pupa of Samia cynthia pryeri was measured throughout diapausing period and developing period. The weight of the pupa decreased during its diapausing period and its developing period. The rate of weight decrease was definite according to the

Foraging activity by an ecosystem engineer, the superb lyrebird, ‘farms’ its invertebrate prey

open access: yesJournal of Animal Ecology, EarlyView.
We show that the superb lyrebird, an ecosystem engineer, undertakes a unique form of resource farming through its foraging activity. By modulating litter and soil habitats on the forest floor, lyrebirds create conditions conducive to their invertebrate prey, increasing richness and biomass and resulting in a remarkable farming feedback loop.

Ordering in red abalone nacre [PDF]

open access: yesarXiv, 2007
Red abalone nacre is an intensely studied biomineral, and yet its formation mechanism remains poorly understood. Here we report quantitative measurements probing the degree of order of the aragonite tablets in nacre, and show that order develops over a distance of about 50 microns.

Larva and Pupa of Cernotina spicata12

open access: yesAnnals of the Entomological Society of America, 1981
The first positively associated larva and pupa of Cernotina are described. Tentative diagnoses are provided for distinguishing them from those of other genera of Nearctic Polycentropodidae, especially Polycentropus s. lat., which Cernotina most strongly resembles. The larva of Cernotina may be distinguished from that of Polycentropus s. lat.

Sex‐specific variation in thermal sensitivity has multiple negative effects on reproductive trait performance

open access: yesJournal of Animal Ecology, EarlyView.
We show sublethal, sex‐specific effects on reproductive traits at a temperature that accelerates development, with female mating success severely reduced and male sterility nearly complete. Our results emphasise that temperatures maximising performance in one trait may negatively and differentially impact sex‐specific reproductive fitness, affecting ...
