The role of river size on fish communities remains underexplored in freshwater ecology. Small streams, despite accounting for 75% of stream length, are more vulnerable to human impacts and often lack legislative protection. Nevertheless, they can serve as refuges and rearing areas for fish, including rare or threatened species. To understand if small streams host distinct fish assemblages, we analysed fish β‐diversity across s...

Cooperative foraging occurs across diverse taxa and facilitates prey acquisition and social learning, particularly when prey is shared among group members. In Resident killer whales ( Orcinus orca ater ), prey sharing is central to how individuals acquire salmonid prey, yet current research has relied primarily on boat‐based observations. Using 10 years of drone‐based imagery, we examined prey sharing behaviors in two populati...

Tropical forests support exceptional biodiversity yet remain underrepresented in long-term wildlife research and monitoring programs due to logistical, financial, and methodological constraints. Conventional ground-based survey methods are often ineffective in these environments, particularly for rare, cryptic, or arboreal species. Drone-mounted thermal cameras (thermal drones) offer a promising alternative by detecting endoth...

Background and aims In Vietnam, Si accumulator crops like rice and maize crops are commonly rotated, but rice straw is often removed for animal feed. This study assessed whether rice straw mulch could improve soil available Si and maize growth. Methods A field experiment was conducted over three years in two fields with different soil Si levels. Four rice straw mulch levels (0, 3.5, 7, and 10.5 t ha⁻ 1 ) were applied during th...

The importance of having visual feedback of the lower-limb to locomotion control, has typically been examined by intermittently occluding the lower visual field (lvf) in repeated obstacle crossing trials. A consistent finding is that foot clearance increases following lvf occlusion. However, there is some evidence that the increase in clearance diminishes with further repetition. This calls into question the importance of lvf...

Antarctic soils are unique from those found nearly anywhere else on Earth yet can still harbor a broad diversity of microorganisms able to tolerate the challenging conditions typical of the continent. For these reasons, microbiologists have been drawn to Antarctica for decades. However, our understanding of which microbes thrive in Antarctic soils and how they to do so remains limited. To help resolve these knowledge gaps, we...
