Managing the Threat of Subsidized Predators for a Threatened Shorebird
Animal Conservation, EarlyView.Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

Beach Cycle and Beach-face Slope on Sandy Beaches.
Kikan Chirigaku, 1998 砕波帯相似パラメーターで近似される, 波の砕波区分図を用いて, ビーチサイクルにおける波の波形勾配とビーチフェイス勾配の関係のモデル的な考察を試みた。ビーチフェイス勾配の経験式より, 波の周期および底質粒径を一定とすると, 沖波波高が大きくなれば, ビーチフェイス勾配は小さくなり, 沖波波高が小さくなるとビーチフェイス勾配は大きくなる。この関係は, 砕波区分図上で, 反時計回りのループとして表すことができる。また, 砕波帯相似パラメーターにより, 砕波型式, 波の反射率, 相対打ち上げ高さが, ビーチサイクルに関連付けられる。

Shallow Surveying in Hazardous Waters [PDF]
, 2009 Of order one importance to any study of nearshore processes is knowledge of the bathymetry in shallow water. This is true for studies on open coast sandy beaches where surf zone dynamics drive the system, inlet environments where bathymetric evolution ...

American Journal of Political Science, EarlyView.Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

How to Fish With Respect: A Transformation of Human‐Fish Relations in Riverside Amazonia
American Anthropologist, EarlyView.ABSTRACT Riverside inhabitants of the Middle Xingu River Basin, in the Brazilian Amazonia, frequently say that it is important to respect animals and the forest spirits who protect them. In recent decades, however, the development of an iced fish industry in the region has changed what respect means and how it is expressed when it comes to fishing ...

Coastal Engineering ProceedingsApproximately 30% of the global ice-free coastline is stated to be sandy (Luijendijk et al., 2018). Sandy beaches hold an important socio-economic value related to tourism and recreation and simultaneously fulfill various ecosystem services like providing food, water and maintaining biodiversity. Sandy systems are among the most dynamic environments in
