Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Do cultural taboos regulate hunting in transitioning Indigenous communities? The case of the Idu Mishmi of Northeast India

People and Nature, EarlyView.
Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

Journal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Petrochemistry and Chemical Features of Lunar Glassy Spherules [PDF]

Symposium - International Astronomical Union, 1972
The major elements of glassy spherules from samples 12001.73, 12057.60 and 12070.37 of lunar fines have been determined by electron probe analysis. The bulk chemistry of these spherules (which are between 200 μm and 62 μm in size) falls in most cases within the range of gabbro-peridotite and gabbro-anorthosite.In individual spherules, the grade of ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...
