A step into the shadows: Evolutionary shifts in fruit structure and dispersal strategies in Asian mycoheterotrophic Ericaceae

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
This study examines how the fruits of non‐photosynthetic forest plants in the Monotropoideae (Ericaceae) have evolved into the diversity observed today. By analyzing four Asian species, we identified a shift from dry, dehiscent fruits that release seeds into the air to fleshy, berry‐like fruits adapted for animal dispersal.

Pitardia resurrected: A new member of subtribe Menthinae (Lamiaceae)

open access: yesTAXON, EarlyView.
Abstract Despite tremendous progress towards clarifying phylogenetic relationships within the mint family (Lamiaceae), uncertainty remains regarding relationships among some major clades as well as the proper placement of some genera. While researching the genus Nepeta, a species from northeastern Morocco, N.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Differences in mammal community response to highway construction across different levels of human land use

open access: yesWildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.
