• No evidence for novel weapons: biochemical recognition modulates early ontogenetic processes in native species and invasive acacias 

  Yannelli, F.A.; Novoa, A.; Lorenzo, P.; Rodriguez, J.; Le Roux, J.J. (2020)

  The Novel Weapons Hypothesis postulates that the release of allelochemicals by alien plants can inhibit the growth of evolutionary naive native plants. On the other hand, when species share a recent evolutionary history, ...

• High spatial turnover in springtails of the Cape Floristic Region 

  Janion-Scheepers, C.; Bengtsson, J.; Duffy, G.A.; Deharveng, L.; Leinaas, H.P.; Chown, S.L. (2020)

• Only the largest terrestrial carnivores increase their dietary breadth with increasing prey richness 

  Ferretti, F.; Lovari, S.; Lucherini, M.; Hayward, M.; Stephens, P.A. (2020)

  Animals should adapt their foraging habits, changing their dietary breadth in response to variation in the richness and availability of food resources. Understanding how species modify their dietary breadth according to ...

• Make open access publishing fair and transparent! 

  Essl, F.; Courchamp, F.; Dullinger, S.; Jeschke, J.M.; Schindler, S. (2020)

• Evidence for Rapoport's rule and latitudinal patterns in the global distribution and diversity of alien bird species 

  Dyer, E.E.; Redding, D.W.; Cassey, P.; Collen, B.; Blackburn, T.M. (2020)

  Aim To quantify global latitudinal patterns in the distributions of alien bird species to assess whether these species conform to Rapoport's rule (i.e. show a positive latitudinal gradient in latitudinal range extent), and ...

• Realised rather than fundamental thermal niches predict site occupancy: implications for climate change forecasting 

  Braschler, B.; Duffy, G.A.; Nortje, E.; Kritzinger-Klopper, S.; du Plessis, D.; Karenyi, N.; Leihy, R.I.; Chown, S.L. (2020)

  Thermal performance traits are regularly used to make forecasts of the responses of ectotherms to anthropogenic environmental change, but such forecasts do not always differentiate between fundamental and realised thermal ...
