Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

Wildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

Implications of climate change for coastal and inter-tidal habitats in the UK [PDF]

, 2013
Coastal habitats are diverse and vary in the extent to which they are shaped by physiographic processes, such as wave action, wind, tides and sediment availability, and the relative influence of terrestrial and marine environments, e.g.

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

Wildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

Persistent elastic behavior above a megathrust rupture patch: Nias island, West Sumatra [PDF]

, 2008
We quantify fore-arc deformation using fossil reefs to test the assumption commonly made in seismic cycle models that anelastic deformation of the fore arc is negligible.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Computational fluid dynamics investigation of wave interactions with damaged coastal cliffs

Results in Engineering
Numerous studies have documented that increasingly intense weather and climate events are amplifying marine wave activity. However, complex links between oceanic storms and coastal environments require further investigation to assess risk and develop ...

Alternating seismic uplift and subsidence in the late Holocene at Madang, Papua New Guinea: Evidence from raised reefs [PDF]

, 2000
Well-preserved mid-late Holocene coral reefs are exposed in low coastal cliffs in the vicinity of the Madang lagoon on the north coast of Papua New Guinea.

Winter Track Survey of the Amur Tiger (Panthera tigris altaica) in the Southwest Primorsky Province of Russia 俄罗斯滨海边疆区西南部东北虎 (Panthera tigris altaica) 冬季足迹调查

Wildlife Letters, EarlyView.
In the winter of 2021/2022, a winter track survey revealed 43–46 tigers (without cubs) in 5.4 thousand km2 of suitable habitats in the Southwest Primorsky Province of Russia. In the same period, a network of camera traps registered 54 adult/subadult tigers here.

Shore platforms and mass movement: a note [PDF]

, 1969
Shore platforms and mass movement phenomena are important elements in the coastal scenery of the British Isles. Both features are particularly well developed along the English Channel coast.

Alongshore variability in wave energy transfer to coastal cliffs

Geomorphology, 2018
Abstract The alongshore distribution of wave energy is believed to be an important control on the spatial variability of coastal erosion. There is, however, a lack of field data quantifying the alongshore variability in wave energy on rock coasts, whereby the relative control of coastline geometry versus foreshore characteristics on wave energy ...
