In the UK, discussion of good citizenship during the COVID-19 pandemic largely focused on compliance and non-compliance with government rules. In this paper, we offer an alternative point of focus. Pandemic governance proceeded not only through rules/morality, but also through freedom/ethics.

This paper argues for closer attention to courtwatching in legal geographical research. Numerous courtwatching programmes exist around the world, and the first part of the paper surveys some of these, giving a sense of their diversity, the challenges they can face, and the influence that they have.

- Antimicrobial resistance (AMR) is a rising public health threat linked to the excessive use of antibiotics in shrimp farming, especially in low- and middle-income countries with lax regulations.
- The integration of aquaculture with local livelihoods and the direct release of untreated waste into water sources contribute to this risk.
- Addressing AMR in shrimp farming is complex due to challenges in tracking antibiotic usage and the reliance on these drugs for disease control, highlighting the need for improved practices and mitigation strategies for a sustainable shrimp industry.
Image-based modeling, and more precisely, Structure from Motion (SfM) and Multi-View Stereo (MVS), is emerging as a flexible, self-service, remote sensing tool for generating fine-grained digital surface models (DSMs) in the Earth sciences and ecology. However, drone-based SfM + MVS applications have developed at a rapid pace over the past decade and there are now many software options available for data processing. Consequently, understanding of reproducibility issues caused by variations in software choice and their influence on data quality is relatively poorly understood.

Article Synopsis
- The study examined the spatial distribution and genetic variation of five tree species in the western Amazon, investigating whether their phylogeographic patterns align with historical processes like Pleistocene refugia.
- Researchers sequenced DNA from 674 individuals across different populations to analyze genetic diversity and structure, finding that shade-tolerant species had higher genetic diversity than pioneer species.
- Results showed that while some genetic groups were identified, the phylogeographic patterns differed significantly among species, suggesting that individual species respond uniquely to geological and climatic changes rather than following a shared biogeographic history.
Sediment and nutrient storage in a beaver engineered wetland.
Earth Surf Process Landf
September 2018
Beavers, primarily through the building of dams, can deliver significant geomorphic modifications and result in changes to nutrient and sediment fluxes. Research is required to understand the implications and possible benefits of widespread beaver reintroduction across Europe. This study surveyed sediment depth, extent and carbon/nitrogen content in a sequence of beaver pond and dam structures in South West England, where a pair of Eurasian beavers (Castor fiber) were introduced to a controlled 1.
