Research on Adaptive Irrigation Decision‐Making Method for the Entire Growth Cycle of Water Spinach Based on Reinforcement Learning

Food Frontiers, Volume 7, Issue 3, May 2026.
An environmentally enhanced proximal policy optimization (EN‐PPO) method is proposed for adaptive irrigation of water spinach across the full growth cycle. By integrating soil moisture, growth stage, rainfall, and evapotranspiration information, the method improves irrigation timing, water‐saving performance, and rainfall utilization while maintaining ...

Human Response to Postglacial Sea Level Change in Jomon Prehistoric Sites Around Lake Ogawara, Northern Japan

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The Jomon culture, characterized by hunting, gathering, and fishing, lasted from approximately 15.5–2.4 ka in the Japanese archipelago. In this study, the shore of Lake Ogawara in northeastern Japan was investigated using coring, fossil analyses, and radiocarbon dating to reconstruct the palaeoenvironmental changes as well as their ...

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Morphology of alluvial fans

, 2017
Alluvial fans are sedimentary deposits growing at the outlet of drainage areas. This position makes them valuable sedimentary records. Three key parameters determine their geometry: the water discharge, the sediment size and the sediment discharge. In this manuscript, based on three series of experiments, we quantify independently the influence of each

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

River Research and Applications, Volume 42, Issue 4, Page 796-811, May 2026.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

River Research and Applications, Volume 42, Issue 4, Page 837-850, May 2026.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,
