Differences in characteristics between naturalized threatened plants and other threatened plants

open access: yesConservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Lectins of Erythrina poeppigiana and Erythrina steyermarkii (Leguminosae): characterization and mitogenic effect

open access: yesRevista de Biología Tropical, 1998
Erythrina species are widely distributed in Costa Rica and known popularly as "poró". In this study, two species were selected, Erythrina poeppigiana and Erythrina steyermarkii. Seed extracts were prepared in phosphate-buffered saline.

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

Sub-zero temperature enables storage of seeds of Caesalpinia echinata Lam

open access: yesJournal of Seed Science
Seeds of brazilwood usually have their germinability quickly reduced if stored under natural conditions. Low temperatures, mainly sub-zero, can extend this viability for at least two years.

The development of insect diversity and ecosystem complexity on green roofs: A review

open access: yesInsect Conservation and Diversity, EarlyView.
A classification system of different roof types is presented to improve consistency in green roof research. Landscape and green roof characteristics influence ecosystem development, but can be further explained by ecological concepts, like neutral and niche theory.

Effects of elevation and microclimatic temperatures on butterfly–flower interaction networks in a Mediterranean mountain range

open access: yesInsect Conservation and Diversity, EarlyView.
We tested how elevation and microclimate influenced butterfly–flower interaction networks at the hottest time of year in a Mediterranean mountain range. Interactions were dominated at all sites by one or two abundant butterfly and flower species, but butterfly networks were more robust to plant species loss at higher elevations. Nectar availability may
