Ecography, EarlyView.Dynamic occupancy models are fundamental for understanding complex species recolonisation processes, as they allow the assessment of both colonisation and persistence probabilities over time. Using a dynamic occupancy model and a large‐scale multi‐year dataset on wolf presence collected in the Italian alpine region between 2014 and 2020, we analysed ...

TreeMig framework ver. 1.0: an R package with GUI to simulate spatio‐temporal forest dynamics
Ecography, EarlyView.Spatio‐temporal vegetation models are essential for simulating dynamics and shifts in species distributions over large areas, particularly under global change. One such model is the dynamic forest landscape model TreeMig. We have developed a framework that makes the model more user‐friendly, improves its functionality, and expands its possibilities ...

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps
Ecography, EarlyView.Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests
Ecography, EarlyView.Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Ecography, EarlyView.Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological

Relationship between new snow density and shape of snow crystals.
Journal of the Japanese Society of Snow and Ice, 1989 新積雪の密度と気象要素および卓越結晶形との関係を詳しく調べるために, 秋田県鹿角市八幡平で6時間毎の観測を実施した.その結果次のことがわかった.1) 新積雪の密度は平均気温の低下と共にやや小さくなり, 平均風速の増加と共にやや大きくなる傾向を示したが, 卓越結晶形の相違による測定値のばらつきは相当大きかった.2) 平均気温が0℃以下のときには, 新積雪の密度は卓越結晶毎に, 雲粒付着の有無およびふぶきの有無を考慮して表わすことができる.

A Novel Multilevel Conceptual Framework for Flood Risk Governance
Environmental Policy and Governance, EarlyView.ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop

Dynamic snow density for snow water equivalent retrieval
, 2020 Snow water equivalent is the amount of water that would form if a pack of snow would melt in place. Snow water equivalent is an important variable in describing global seasonal snow cover.
