Four new deciduous species of Hyperacanthus (Rubiaceae: Gardenieae) from western Madagascar: the sofikomba alliance.
The genus comprises 11 species, nine in Madagascar and two in Africa, although many Madagascan species remain undescribed. All Madagascan species of are evergreen trees occurring in humid and semi-humid forest. Four deciduous species occur in the dry forests of northern, western, and southern Madagascar but are unknown to science.... -

The power of citizen science to advance fungal conservation.
Fungal conservation is gaining momentum globally, but many challenges remain. To advance further, more data are needed on fungal diversity across space and time. Fundamental information regarding population sizes, trends, and geographic ranges is also critical to accurately assess the extinction risk of individual species. However, obtaining these data is... -

New taxa of Barleria sect. Prionitis (Acanthaceae) from the Horn of Africa biodiversity hotspot in Somalia.
Two new taxa in Barleria L. sect. Prionitis Nees (Acanthaceae) are described from Somalia, namely Barleria biramosa Defty & I.Darbysh. from central Somalia and B. compacta Malombe & I.Darbysh. subsp. minima I.Darbysh. & Defty from the northeast coastal region. These taxa are further endemics of the Horn of Africa biodiversity...Defty, Ellie ; Darbyshire, Iain

A further new species of Isoglossa (Acanthaceae) from the Eastern Arc Mountains of Tanzania.
I.Darbysh. & Hemp (Acanthaceae), from submontane moist forest at Mwala in the South Pare Mountains of northeastern Tanzania, is described and illustrated. This species is considered to be related to (S.Moore) Lindau and (Vahl) Brummitt & J.R.I.Wood, which are widespread in the montane forests of eastern Africa, but it clearly...Darbyshire, Iain ; Hemp, Andreas

A new and possibly carnivorous species of Crepidorhopalon (Linderniaceae) from Mozambique.
The new species Crepidorhopalon droseroides from Mozambique is described and illustrated. It represents the third strict Mozambique endemic in Linderniaceae, and it differs from all known species of Crepidorhopalon in the long sticky glandular hairs. The hypothesis that the species may be carnivorous is discussed. The Conservation Status is preliminarily...Fischer, Eberhard ; Wursten, Bart ; Darbyshire, Iain

Drivers of species knowledge across the tree of life.
Knowledge of biodiversity is unevenly distributed across the Tree of Life. In the long run, such disparity in awareness unbalances our understanding of life on Earth, influencing policy decisions and the allocation of research and conservation funding. We investigated how humans accumulate knowledge of biodiversity by searching for consistent relationships...Mammola, Stefano ; Adamo, Martino ; Antić, Dragan ; Calevo, Jacopo ; Cancellario, Tommaso …

A multi-taxon analysis of European Red Lists reveals major threats to biodiversity.
Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species’ distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of... -

The ECAT dataset: expert-validated distribution data of endemic and sub-endemic trees of Central Africa (Dem. Rep. Congo, Rwanda, Burundi).
In this data paper, we present a specimen-based occurrence dataset compiled in the framework of the Conservation of Endemic Central African Trees (ECAT) project with the aim of producing global conservation assessments for the IUCN Red List. The project targets all tree species endemic or sub-endemic to the Central African... -

Prioritising species for monitoring in a South African protected area and the Red List for plants.
Protected areas (PA) in biodiversity hotspots face the challenge of monitoring large numbers of locally rare and threatened plant species at times with limited budgets. Prioritising species according to their local extinction risk could help PA managers to decide which species to monitor. However, there is often very little information...Cowell, Carly R. ; Nic Lughadha, Eimear ; Anderson, Pippin M. L. ; Leão, Tarciso ; Williams, Jenny …

Systematics and conservation of British and Irish orchids: a "state of the union" assessment to accompany Atlas 2020.
Prompted by concurrent completion of the latest plant atlas for Britain and Ireland, the orchid flora of these islands is reviewed in detail, focusing on 21st century progress in both systematics research and formal conservation categorisation under IUCN criteria. DNA-based phylogenies consistently circumscribe monophyletic groups that constitute obvious genera, though... -
