Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

European mistletoe shares a similar demographic strategy with non‐parasitic plants

Journal of Ecology, Volume 114, Issue 5, May 2026.
European mistletoe (Viscum album) does not have a distinct demographic strategy from non‐parasitic plants, as quantified by time‐based life history traits. We found that mistletoe vital rates were driven by mistletoe size and position in the host tree.

Implicações da agregação espacial de parasitas para a dinâmica populacional na interação hospedeiro-parasita Implications of spatial aggregation of parasites for the population dynamics in host-parasite interaction

Revista de Saúde Pública, 1997
São discutidos aspectos relacionados ao padrão comumente observado de distribuição agregada de parasitas na população-hospedeira. Geralmente observa-se que a maioria dos hospedeiros alberga poucos parasitas, enquanto que poucos hospedeiros albergam a ...

Cowbirds use conspecific social information to detect host nests in the wild

Ibis, Volume 168, Issue 2, Page 799-804, April 2026.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

People and Nature, Volume 8, Issue 3, Page 528-540, March 2026.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.
