Simulated climate change causes asymmetric responses in insect life history timing potentially disrupting a classic ecological speciation system

A. C. R. Lackey, P. M. Deneen, G. J. Ragland, J. L. Feder, D. A. Hahn, T. H. Powell

This study shows that simulated climate change causes asymmetric phenological responses in two sympatric fly populations, potentially disrupting ecological speciation by reducing temporal isolation.

Host-enemy interactions provide limited biotic resistance for a range-expanding species via reduced apparent competition

K. M. Prior, D. G. Jones, S. A. Meadley-Dunphy, S. Lee, A. K. Milks, S. Daughton, A. A. Forbes, T. H. Powell

The paper examines how a range-expanding oak gall wasp interacts with parasitoid wasps in its native and expanded ranges, finding reduced apparent competition due to phenological divergence of enemy assemblages.

Latitudinal gradient in species diversity provides high niche opportunities for a range-expanding phytophagous insect

D. G. Jones, J. Kobelt, J. Ross, T. H. Powell, K. M. Prior

The paper investigates whether oak gall wasp communities follow a latitudinal diversity gradient and have weaker interactions at higher latitudes, potentially creating niche opportunities for range-expanding species.

A rapidly evolved shift in life history timing during ecological speciation is driven by the transition between developmental phases

T. H. Powell, A. D. Nguyen, Q. Xia, J. L. Feder, G. J. Ragland, D. A. Hahn

The study identifies the end of the pupal diapause maintenance phase as the main driver of a recently evolved phenological shift in Rhagoletis pomonella.
