Oikos, EarlyView.The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.

α‐Functionalization of Polyethers With NHS Ester for Orthogonal Conjugation
Journal of Polymer Science, EarlyView.In this work, we synthesize an N‐hydroxysuccinimide (NHS) ester initiator for epoxide polymerizations. We demonstrate functional group tolerance of monomers, compositional control, and molecular weight control. We show successful conjugation of NHS‐ester end group polymers with various targets such as nanoparticles (NPs), polymers, small molecules, and

Conservation challenges and opportunities for native apple (Malus) species in Canada
PLANTS, PEOPLE, PLANET, EarlyView.Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

A survey of natural parasitism of mirid bugs by parasitoids on apples and pears in Norway [PDF]
, 2008 Mirid bugs are important pests in both integrated and organic fruit production. In a survey in 2006 the proportion of mirids parasitized by parasitoids was investigated in 18 Norwegian orchards.

PLANTS, PEOPLE, PLANET, EarlyView.Urban agriculture depends on insect pollination, but knowledge gaps persist due to difficulties accessing diverse growing spaces. We developed a citizen science approach for monitoring insect visits to crops and compared grower‐collected data to that of a trained researcher while also gathering participant feedback.
