We describe a new species of spiny (Solanumsubg.Leptostemonum), endemic to the Brazilian Atlantic Forest and associated with granitic outcrops (inselbergs or sugar loaf mountains). Gouvêa & Giacomin, is morphologically similar to the poorly known Hiern, but is a heavily armed, much more robust plant with stellate-glandular indumentum. Together with , it is morphologically related to some species of such as Vell., H.Wendl., and Moric. that share strongly accrescent calyces, large leaves with the bases decurrent on to the petiole, pendent simple inflorescences and large, robust flowers. The new species is restricted to a few known populations in southern Bahia and north-eastern Minas Gerais states and conservation efforts are needed.

Background: Armed conflicts can severely impact food security by displacing farmers, destroying farms and agricultural infrastructure, disrupting supply chains, and limiting governance control over highly volatile food markets. In this study, we aim to gain an initial understanding of the impact of the ongoing Israel-Hamas War on local food production in Israel.
Methods: This study examined the challenges of food production in the Gaza Envelope region, a border area in Israel that has been profoundly affected by the recent conflict.

In Colombia, the long-lasting internal conflict heavily shaped the socio-ecological context and imposed relationships that persisted after the peace agreement was signed in 2016. One question of interest is whether policies or interventions conceived to attain desirable goals for the post-conflict society may be effective or, rather, if the constraints imposed by the conflict scenario might produce unintended effects, either on the environmental or the social side. To explore this issue, we envisaged the socio-ecological system as a parsimonious set of characteristic ecological and social variables within the conflict-related framework and reconstructed their interactions, exploiting elicitation-based information and the literature.
