Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae)
Sociobiology, 2014 Despite the fact that Meliponini bee lost their sting apparatus (stingless bees), they did not lose their ability to defend themselves. A variety of defensive strategies is described for the group, such as bitting and resin deposition.

Male Rats Respond to Their Own Alarm Pheromone
Journal of Veterinary Medical Science, 2012 Pheromones are defined as substances released from an individual (donor) that influence a second individual (recipient) of the same species. However, it is unclear whether mammalian pheromones can affect the donor itself. To address this question, the effect of self-exposure to an alarm pheromone was examined.

Australian Veterinary Journal, EarlyView.Despite a frequent misconception that behavioural concerns are diagnoses of exclusion, medical conditions and behavioural disorders are frequently inter‐related. In human medicine, the ‘multidisciplinary team’ approach (MDTA) is considered the most efficacious way of managing patients with complex and chronic health conditions.

Alarm Pheromones—Chemical Signaling in Response to Danger [PDF]
, 2010 Many animals respond to the threat of predation by producing alarm signals that warn other individuals of the presence of danger or otherwise reduce the success of predators. While alarm signals may be visual or auditory as well as chemical, alarm pheromones are common, especially among insects and aquatic organisms. Plants too emit chemical signals in

Entomologia Experimentalis et Applicata, EarlyView.Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
