Notes on Justicia sect. Monechma (Acanthaceae) in Angola, including two new species
Two new species of Justicia sect. Monechma, Justicia cubangensis and J. eriniae, are described from Angola. Their affinities are reviewed, together with a discussion on the correct generic name to apply to these species. A conspectus of Justicia sect. Monechma ‘Group I’ in Angola is presented, including a key to...Darbyshire, I ; Goyder, D

Open-source data reveal how collections-based fungal diversity is sensitive to global change
Premise of the Study: Fungal diversity (richness) trends at large scales are in urgent need of investigation, especially through novel situations that combine long-term observational with environmental and remotely sensed open-source data. Methods: We modeled fungal richness, with collections-based records of saprotrophic (decaying) and ectomycorrhizal (plant mutualistic) fungi, using an...Andrew, C ; Büntgen, U ; Egli, S ; Senn-Irlet, B ; Grytnes, J …

Novelties in Hyptidendron (Hyptidinae – Lamiaceae) from Brazil: A new species and a rediscovery
A new species, Hyptidendron roseum, from the Chapada dos Veadeiros region, Goiás state, is described and illustrated. It can be distinguished from its congeners by the combination of inflorescences composed of a unilateral cymose structures, sessile to subsessile leaves, a ring of trichomes in the throat of the calyx tube,...Antar, G ; Harley, R ; Pastore, J ; Sano, P

New land in the Neotropics: a review of biotic community, ecosystem, and landscape transformations in the face of climate and glacier change
The high tropical Andes are rapidly changing due to climate change, leading to strong biotic community, ecosystem, and landscape transformations. While a wealth of glacier, water resource, and ecosystem-related research exists, an integrated perspective on the drivers and processes of glacier, landscape, and biota dynamics is currently missing. Here, we...Cuesta, Francisco ; Llambí, Luis ; Huggel, Christian ; Drenkhan, Fabian ; Gosling, William …

Mutualistic interactions reshuffle the effects of climate change on plants across the tree of life
Climatically induced local species extinctions may trigger coextinction cascades, thus driving many more species to extinction than originally predicted by species distribution models. Using seven pollination networks across Europe that include the phylogeny and life history traits of plants, we show a substantial variability across networks in climatically predicted plant...Bascompte, Jordi ; García, María ; Ortega, Raúl ; Rezende, Enrico ; Pironon, Samuel

Morphological and functional seed traits of the wild medicinal plant Dioscorea strydomiana, the most threatened yam in the world
Morphological and functional seed traits have important roles in characterising the species regeneration niche and help to understand the reproductive biology of rare and threatened plants, which can thus support appropriate plant conservation measures. Seed morphometric and dispersal kinetics of the critically endangered Dioscorea strydomiana were measured and compared with...Mattana, E ; Gomez-Barreiro, P ; Lötter, M ; Hankey, A ; Froneman, W …

Mesosphaerum caatingense (Lamiaceae), a new species from the semi-arid Caatinga Region of Northeast Brazil
A new species, Mesosphaerum caatingense Harley & J.F.B.Pastore (Lamiaceae: tribe Ocimeae: subtribe Hyptidinae), is described from the semi-arid Northeast region of Brazil known as the Caatinga biome, included under the domain of the STDF (Seasonally Tropical Dry Forest). The generic placement and its conservation status are assessed and its phenology...Harley, R ; Pastore, J ; de Souza Soares, A ; Fernando, E ; Mota, M

Molecular phylogeny and morphology of Elatostema s.l. (Urticaceae): Implications for inter- and infrageneric classifications
Elatostema s.s. (Urticaceae) comprises approximately 500 species of herbs and subshrubs distributed in tropical and subtropical Asia, Australasia, and Africa. The delimitation of Elatostema s.s. and the closely related genera Elatostematoides, Pellionia, and Procris has long been problematic because of the large number of taxa and presumed homoplasy among diagnostic...Tseng, Yu-Hsin ; Monro, Alex ; Wei, Yi-Gang ; Hu, Jer-Ming

Mechanisms in mutualisms: a chemically mediated thrips pollination strategy in common elder
The concept of flower-feeding thrips as pollinating insects in temperate regions is rarely considered as they are more frequently regarded to be destructive florivores feeding on pollen and surrounding plant tissue. Combining laboratory and field-based studies we examined interactions between Sambucus nigra (elderflower) and Thrips major within their native range... -

Linking democracy and biodiversity conservation: Empirical evidence and research gaps
Increasing human pressure threatens plant and animal species with extinction worldwide. National political institutions constitute an important arena for biodiversity conservation. Yet, the relationship between how democratic these national institutions are and a country’s efforts towards and track-record for biodiversity conservation remains poorly understood. In this review, we outline the...Rydén, Oskar ; Zizka, Alexander ; Jagers, Sverker ; Lindberg, Staffan ; Antonelli, Alexandre

Lessons from the past and the future of food.
Perspectives from the recent and ancient past are largely underutilized in modern sustainability or food systems studies. However, information about regional crop histories and land use systems through time can add essential value and context to debates concerning future agricultural strategies and food security. In particular, archaeological and anthropological research...Reed, Kelly ; Ryan, Philippa

Least concern to endangered: Applying climate change projections profoundly influences the extinction risk assessment for wild Arabica coffee
Arabica coffee (Coffea arabica) is a key crop in many tropical countries and globally provides an export value of over US$13 billion per year. Wild Arabica coffee is of fundamental importance for the global coffee sector and of direct importance within Ethiopia, as a source of harvestable income and planting...Moat, Justin ; Gole, Tadesse ; Davis, Aaron

Leaf surface development and the plant fossil record: stomatal patterning in Bennettitales
Stomata play a critical ecological role as an interface between the plant and its environment. Although the guard-cell pair is highly conserved in land plants, the development and patterning of surrounding epidermal cells follow predictable pathways in different taxa that are increasingly well understood following recent advances in the developmental...Rudall, Paula ; Bateman, Richard
