Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.

Land degradation: links to agricultural output and profitability [PDF]

To understand land degradation and assess policy responses, knowledge is needed of the bio-physical causes, the economic effects on farms and the incentives farmers face to avoid or ameliorate the degradation.

Population Genetic Structure and Species Delimitation of a Widespread, Neotropical Dwarf Gecko [PDF]

, 2019
Amazonia harbors the greatest biological diversity on Earth. One trend that spans Amazonian taxa is that most taxonomic groups either exhibit broad geographic ranges or small restricted ranges.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

The mammals of Northern Melanesia: biogeography, systematics and ecology

Frontiers of Biogeography, 2015
Northern Melanesia's mammals are poorly known, and perceived deficiencies in faunal records and taxonomic descriptions have, until now, hindered detailed analyses.

A new proposal for a statistically-derived biogeographical regionalization of Algeria, North Africa

Mediterranean Botany
Most proposals relating to the biogeographic regionalization of Algeria have been made by traditional qualitative method (geography, geology, climatology, vascular flora), on the basis of expert’s opinions. A new biogeographic regionalization of Algeria

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.
