296 A phylum-wide survey reveals multiple independent gains of head regeneration in Nemertea.

295 Benefits of zebra stripes: Behaviour of tabanid flies around zebras and horses.

294 Proximity sensors on common noctule bats reveal evidence that mothers guide juveniles to roosts but not food.

293 Species delimitation in endangered groundwater salamanders: Implications for aquifer management and biodiversity conservation.

292 Ultraviolet fluorescence discovered in New World flying squirrels.

291 Marine mammal and bird diversity is highest in polar regions, owing to the availability of cold, slow prey.

290 Avian UV vision enhances leaf surface contrasts in forest environments.

289 Comparison of Sporormiella dung fungal spores and oribatid mites as indicators of large herbivore presence: evidence from the Cuzco region of Peru.

288 A recent shift in the pigmentation phenotype of a wild Neotropical primate.

287 Biomechanics of the peafowl’s crest reveals frequencies tuned to social displays.

286 Cats use hollow papillae to wick saliva into fur.

285 Exploring mechanisms and origins of reduced dispersal in island Komodo dragons.

284 Time-space–displaced responses in the orangutan vocal system.

283 Remarkable muscles, remarkable locomotion in desert-dwelling wildebeest.

282 A dopaminergic mesocortical circuit in juvenile zebra finches detects the presence of an adult zebra finch tutor and helps to encode the performance of the tutor, facilitating the cultural transmission of vocal behaviour.
