Core symbionts, age at inoculation and diet affect colonization of the bumblebee gut by a common bacterial pathogen

Journal of Animal Ecology, EarlyView.
This paper examines ecological interactions within the bumblebee gut microbiome and between the microbiome and host using field sampling and controlled experiments. We demonstrate that non‐core bacteria occur frequently in high abundance in wild bumblebee gut microbiomes.

Division of labour and risk taking in the dinosaur ant, Dinoponera quadriceps [PDF]

, 2013
The success of social insects can be largely attributed to division of labour. In contrast to most social insects, many species with simple societies contain workers which are capable of sexual reproduction.

The effectiveness of indirect plant defence is dependent on plant competition

Journal of Ecology, EarlyView.
We investigated whether plant competition influences the effects of parasitoids on plant fitness. Using a full‐factorial open‐field experiment, we tested three levels of herbivory and plant competition. Our results show that parasitoids enhance plant fitness, but only in high plant density, when competing plants are attacked by unparasitized herbivores,

The Effect of the Transplantation of the Postcritical Brain of the Pupa upon the Termination of the Pupal Diapause in Samia cynthia pryeri. [PDF]

, 1973
The effect on the termination of the diapause of the recipient pupa of the transplantation of the precritical brain for activation of the developing pupa was compared with that of the postcritical brain in a cynthia silkworm, Samia cynthia pryeri.

Evidence for transient deleterious thermal acclimation in field recapture rates of an invasive tropical species, Bactrocera dorsalis (Diptera: Tephritidae)

Insect Science, EarlyView.
Abstract Knowing how environmental conditions affect performance traits in pest insects is important to improve pest management strategies. It can be informative for monitoring, but also for control programs where insects are mass‐reared, and field‐released.

Resource use of crucian carp along a lake productivity gradient is related to body size, predation risk, and resource competition

Ecology of Freshwater Fish, Volume 32, Issue 1, Page 10-22, January 2023., 2023
Abstract Generalist fish species can feed on a wide resource spectrum and across trophic levels depending on resource availability and trophic interactions. Crucian carp (Carassius carassius) represents a good candidate species to investigate variation in the trophic ecology of generalist fish as it can be found in highly variable fish communities and ...
