Most people think of animal communication as sounds, dances or smells. But many insects communicate through vibrations that travel through plants. I'm very excited to share this interview about my research on vibrationally duetting #treehoppers at STRI in Panama! stri.si.edu/story/judith...

Success varies substantially by manuscript characteristics. Authors at the most prestigious institutions are accepted at 3.4x the rate of the least prestigious. Large teams (10+ authors) at 3x the rate of small teams. And US/Canada-based authors at 3.3x the rate of China-based authors /4
This plot shows acceptance rates varying substantially by topic, team size, prestige, and region of corresponding author, for both journals.

Biological sex is binary, except when it’s not (isogamy). It’s defined by gamete size, except in large-spermed males. It’s binary, but one can be both at once (hermaphrodites), neither (sterile) or switch (clownfish), and it might depend on temperature (crocodiles) or parasites (Wolbachia). (1/3)

Illustration of a Tiger Lily from Edwards's Botanical Register (1829-1847), showing a large, vibrant orange flower with six broad, curved petals speckled with dark spots. The flower’s stamens and pistil are prominently displayed in the center, with long anthers. Below, the stem supports multiple elongated, lance-shaped green leaves arranged in whorls, each leaf featuring detailed parallel veins. The artwork is finely detailed, emphasizing the plant’s structure and coloration against a plain background.

Historical illustration from the 1912 "Handbook of Birds of Eastern North America," showing detailed black-and-white side profiles of 15 different duck heads, each labeled with its species name. The ducks include Baldpate, Green-winged Teal, Blue-winged Teal, Shoveller, Pintail, Wood Duck, Redhead, Canvasback, American Scaup Duck, American Golden-eye, Bufflehead, Old Squaw, Greenland Eider, White-winged Scoter, and Ruddy Duck. Each head is carefully drawn to highlight distinctive beak shapes, feather patterns, and plumage details, arranged in a grid labeled "Plate XII." The image reflects early 20th-century ornithological study and documentation but is unrelated to the keyword "apple."

Illustration from "Brehms Tierleben" (1911-19) depicting a thick-tailed possum clinging to a large, cylindrical yellow flower with fine, hair-like petals. The possum has soft brown fur, large dark eyes, rounded ears with pink insides, and a long, thick tail wrapped partially around the flower. Green leaves and stems surround the flower at the base. The detailed, naturalistic style highlights the possum’s cuddly appearance and its close interaction with the flowering plant. The background is a muted blue, emphasizing the animal and flora in the foreground.
