A ‘resident’ pod of killer whales (Orcinus orca) off San Juan Island in Washington State, USA. Pilot et al. (pp. 20–31) show that dispersal from these social groups was rare, but that male mediated gene flow continues during temporary interactions among different pods and populations, including populations that show divergent mtDNA haplotypes.

A Sitka spruce (Picea sitchensis) forest on Kodiak Island, Alaska. This 400 to 500-year-old population is the tip of post-Quaternary migration of Sitka spruce. Large, putative founders are evident within a dense, younger forest (see Mimura & Aitken, pp. 249–258). Photo: Sally N. Aitken.
The skull of Smilodon fatalis (Department of Earth Sciences, University of Bristol). The evolution of biting performance in living and extinct cats, including the sabre-toothed cat S. fatalis, is only moderately constrained by phylogeny, and its nonphylogenetically structured variance remains largely unexplained (see Sakamoto et al., pp. 463–478).

The Madagascar ground gecko (Paroedura picta) is becoming a popular laboratory lizard model species. Starostová et al. (pp. 670–677) show that sexual size dimorphism correlates with body size across species of the genus Paroedura. Moreover, they found that the same trend can be induced intraspecifically by differences in thermal environment. Photo: Lukáš Kratochvíl. A vigilant yellow-bellied marmot (Marmota flaviventris) at the Rocky Mountain Biological Laboratory, Colorado, USA. Blumstein et al. (pp. 879–887) report that the time allocated to anti-predator vigilance in marmots is heritable and is weakly correlated with locomotor performance. Interestingly, faster marmots allocate more time to vigilance while slower marmots allocate less time. Photo: Arpat Ozgul.

A syrphid fly (Eupeodes luniger) visiting a flower of Narcissus papyraceus, a species with style dimorphism. Short-tongued pollinators (such as syrphids) fail to transfer pollen to short-styled flowers and may provoke the loss of this morph in most populations. See Pérez-Barrales & Arroyo, pp. 1117–1128.

Juvenile red-eyed treefrogs (Agalychnis callidryas) from different larval environments. The relative impact of the larval environment on growth and differentiation explains allometric differences in shape observed among post-metamorphic individuals (see Gomez-Mestre et al., pp. 1364–1373). Photo: Karen M. Warkentin. Meerkat (Suricata suricatta) pup surrounded by adults grooming one another. Adults care for young cooperatively, and variation in this behaviour is consistent within individuals over time (see English et al., pp. 1597–1604).

Like all orb-weavers, Gasteracantha sappen from New Britain (c. 70 mg body weight) spins an elegant web of fine yet strong silk to catch prey. Sensenig et al. (pp. 1839–1856) report that larger spider species generally produce better quality silk and webs, likely to meet the challenges of capturing larger prey. After controlling for body size, however, they find a significant tradeoff between spinning behaviours and silk, where species producing sparser web architectures utilize better quality silk. Orb-weaving spiders represent a particularly strong example of coevolution between biomaterials and behaviour. Photo: Piotr Naskrecki (from Relics, University of Chicago Press, 2011, in press).

A family of barn owls (Tyto alba) breeding in a nest-box located in a farm in Switzerland. Roulin et al. (pp. 2046–2053) reveal that the barn owl’s daily regulation of glucocorticoids is associated with melanin-based coloration, but differently so in males and females. This suggests that individuals of different colours do not have the same circadian rhythms. Photo copyright Alex Labhard. Cleaner gobies (Elacatinus oceanops) removing parasites from a green moray eel (Gymnothorax funebri). Interactions with predators have shifted from one of antagonism to cooperation within the lineage of Caribbean gobies, as stripe colours have evolved to increasingly deter attacks. See Lettieri & Streelman, pp. 2289–2299. Photo: Paddy Ryan. Examples of mutualism. Top left: A heliconius butterfly feeding on the flower of ‘hotlips’ (Psychotria sp.) in Panama. Top right: A fungus-growing, leaf-cutter ant from Panama (Pseudomyrmex sp.), here seen tending the fungus garden in its subterranean colony. Bottom left: The fruit-eating bat (Artibeus literatus) taking off with a large fig in its mouth. Bottom right: A king spider orchid (Caldenia sp.) being visited by its pollinator, a male parasitic wasp which is attracted to the flower by a faux female wasp pheromone. See Leigh, pp. 2507–2528.
