Summary: Rearing larval rainbow trout in high NaCl reveals support for the ‘ammonia hypothesis’, which posits that ammonia excretion is the earliest gill function over development and may drive gill ontogeny.


Summary: Overnight hypoxia combined with warm acclimation increases the hypoxia tolerance of salmonids while upper critical temperature is reduced in a species-specific manner.

Highlighted Article: The target of ivermectin, the glutamate-gated chloride channel, has four splice isoforms that are expressed in neuronal tissues in the head and thorax of A. gambiae across various physiological states.

Highlighted Article: Antibodies against the glutamate-gated chloride channel of A. gambiae reduce the survivorship of three mosquito disease vectors.

Summary: An integrative mechanism of metabolic scaling is proposed: species with a larger cell size have a smaller metabolic scaling exponent as they face more pronounced surface/volume limits.

Summary: The physiological flexibility of Cape white-eyes will aid them in coping with the 4°C increase predicted for their range by 2080.

Highlighted Article: Octopus skin senses light independent of the eyes, causing chromatophores in the skin to expand, probably via the same r-opsin phototransduction genes used for vision.

Summary: Light exposure via ear canals has a significant effect on brain encephalopsin expression and plasma and adrenal gland monoamine production in the mouse.

Summary: Even very small polychaetes can extend burrows through muds by fracture; helical muscles may enable worms to apply larger radial forces, facilitating burrow extension by fracture.

Summary: Controlled feeding trials illustrate the effects of exogenous grit on the microscopic tooth wear of hoofed mammals, with implications for paleoecological analyses.

Highlighted article: The bursa copulatrix, a female reproductive organ that processes the male ejaculate in butterflies and moths, exhibits extreme state-dependent proteolytic activity using a complement of nine highly expressed proteases.

Summary: Microspectrophotometry and opsin expression reveals four single cone classes without intraspecific differentiation, providing the first evidence of UV sensitivity in agamid lizards.

Summary: Morphological and behavioural estimations of psyllid visual acuity suggest that varying needs of species for movement in relation to microhabitat preference mediate trade-offs between light sensitivity and spatial resolution.

Summary: Butterflyfishes produce a diversity of high- and low-frequency sounds for social communication in their noisy coral reef environment.

Summary: Butterflyfish detect sound pressure to enhance hearing and aid social communication in a noisy environment.

Highlighted Article: Squid and cuttlefish skin chromatophores contain rhodopsin, G and sTRP channels, which are necessary components for photoreception.

Summary: Flow characteristics impact the degree to which fish rely on lateral line information for rheotaxis.
