Previous studies reported that habitat degradation and alteration (e.g., urbanization, agricultural intensification, and abandonment, as well as contaminants) led to frog population decline, which has become a serious global ecological issue. However, the combined effects of midsummer drainage and agricultural modernization on tadpole populations are rarely investigated. In this study, we evaluated the effects of human activity-induced water management and the type of drainage system in paddy fields on the survival of Zhangixalus arboreus in central Japan. Our results revealed that the midsummer drainage negatively affected tadpole survival, whereas the modern drainage system showed no influence. This study provides a useful way to better understand the survival of frog populations in the paddy field ecosystems.

Article Synopsis
- Restoration of peatlands can lead to shifts in plant communities similar to natural, pristine conditions.
- Traditional field monitoring of vegetation is too labor-intensive for all sites; instead, remote sensing offers a more efficient option.
- Using data from Finnish peatlands and satellite imagery, researchers found that certain optical satellite images effectively track vegetation changes, especially in less densely forested areas.
Population model analyses of the combined effects of insecticide use and habitat degradation on the past sharp declines of the dragonfly Sympetrum frequens.

In recent decades, many dragonfly species have become threatened with extinction. For example, populations of Sympetrum frequens, one of the most common dragonflies in rice paddy fields in Japan, decreased sharply around the late 1990s in many regions. Although previous studies suggested that the use of systemic insecticides (particularly fipronil) was likely a major cause of the decline, agronomic factors other than insecticide use and the combined effects of both have been not examined.

The McMurdo Dry Valleys are the largest single ice-free area in Antarctica, and of considerable scientific and conservation value as an extreme polar desert. This is recognised through the McMurdo Dry Valleys Antarctic Specially Managed Area (ASMA), where management's goals focus on protection of its unique features, while facilitating science access. Using a mix of remote sensing and existing cartography, we have identified over 6000 lakes and ponds in the ASMA.

Countermeasures to reduce radiocesium (134Cs and 137Cs) uptake by crops have been implemented in farmlands affected by the Fukushima nuclear accident in 2011. A widely practiced countermeasure is the application of potassium (K). Long-term soil K maintenance is a key issue due to the long physical half-life of 137Cs (30 years).
