Scientists 'scent train' honeybees to boost sunflowers' seed production

If you want a dog to hunt something down, it helps to let them sniff an item to pick up the scent. Now, researchers have found that scent training honeybees might work in a similar way -- and that this approach could make bees more efficient in pollinating crops. The findings show that honeybees given food scented with sunflower odors led to a significant increase in sunflower crop production. View the source article

DNA unlocks a new understanding of coral

A new study challenges more than 200 years of coral classification. Researchers say the 'traditional' method does not accurately capture the differences between species or their evolutionary relationships. They developed a new genetic tool to help better understand and ultimately work to save coral reefs. View the source article

African wild dogs have vestigial first digit and muscular adaptations for life on the run

African wild dogs (Lycaon pictus) are known for their unique hunting style, often referred to as 'exhaustive predation', in which they chase their prey to exhaustion, rather than hunting using speed, strength, or stealth. They are also unique among the dog clade in having only four full digits on their front paws. Until recently, it was unclear how these unique behavioral and anatomical features would affect their forelimb morphology. View the source article

Why flat-faced dogs remain popular despite health problems

Owners of bulldogs, French bulldogs and pugs are highly likely to want to own their breed again in the future, and to recommend their breed to other owners, according to a new study. The development of breed loyalty toward these so-called brachycephalic (flat-faced) dogs may lead to their continued proliferation and popularity, despite their substantial health risks.

Free-roaming dogs prevent giant pandas from thriving in the wild

Dogs are still menacing giant pandas. This is in part, because nature reserves in China are often closely connected to human settlements where dogs roam free. Dogs can roam over 10 km in a night and some feral dogs have even set up permanent residence in the reserves. View the source article

More than one cognition: A call for change in the field of comparative psychology

Researchers argue that cognitive studies in comparative psychology often wrongly take an anthropocentric approach, resulting in an over-valuation of human-like abilities and the assumption that cognitive skills cluster in animals as they do in humans. The authors advocate for philosophical and procedural changes to the discipline that would lead to a better understanding of animal minds and the evolution of multiple forms of cognition.
