Multi-Epoch Robust DI-Optimal Ground Control Point Network Design for Georeferencing of Google Earth Imagery

Geomatics
Ground Control Points (GCPs) are essential for accurate georeferencing of optical imagery; however, their selection is often heuristic and affected by temporal changes in image geometry.

Exploring the legal, policy, ethical and practical implications of digitisation of botanical and fungal collections

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1076-1086, July 2026.
Societal Impact Statement Dried plant and fungal specimens held in collections provide a unique asset to understand the natural world and inform conservation approaches. By creating freely available, digital images of these collections, these specimens can be used by more scientists from around the globe to ask research questions and apply new ...

Climate change‐driven expansion of goosegrass highlights risks to global food production

Pest Management Science, Volume 82, Issue 7, Page 6494-6508, July 2026.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, Volume 251, Issue 2, Page 768-781, July 2026.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Documenting biodiversity with digital data: comparing and contrasting the efficacy of specimen‐based and observation‐based approaches

New Phytologist, Volume 251, Issue 2, Page 721-736, July 2026.
Summary Digitized herbarium specimens and iNaturalist observations provide invaluable plant biodiversity data. Combining these two data sources could create a more holistic representation of local biodiversity; however, understanding biases inherent to each is critical to determine how to best combine and utilize these data.

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions

New Phytologist, Volume 251, Issue 2, Page 677-688, July 2026.
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

Stepping Up or Stepping Out? Sustainable Livelihood Resilience, Heterogeneous Strategies and Poverty Alleviation Among Retired Fishermen in the Yangtze River Basin

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The ‘Ten‐Year Fishing Ban’ policy in the Yangtze River Basin has compelled over 230,000 fishermen to cease fishing and transition to alternative livelihoods, making their post‐ban livelihood development critical to the policy's long‐term effectiveness. Drawing on household survey data from Hubei and Hunan provinces—which account for nearly 40%

Georeferencing River Networks Using Spatial Reasoning

This paper is concerned with automatic georeferencing of river networks from raster images such as aerial photos or maps. Determining reasonable assignments between a given network of rivers derived from a textual description and an image is subject to ...

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.
