The geography of connectivity shapes plant endemism hotspots

Ecography, EarlyView.
The high biodiversity in mountains is attributed to species accumulation from dispersal, high habitat heterogeneity and local speciation. Landscape connectivity thereby influences colonization and speciation processes, making its net effect on biodiversity challenging to understand.

Generalised bumblebee–flower interactions demonstrate weak floral niche partitioning despite a high bee diversity

Ecography, EarlyView.
Niche partitioning is one of the key mechanisms allowing species coexistence and is especially relevant in species‐rich communities. For pollinators, morphology is a major axis in which species differentiate their foraging niche, as it influences the match with flower morphology. Bumblebees Bombus spp.

Mechanisms producing different precipitation patterns over north‐eastern Italy: insights from HyMeX‐SOP1 and previous events [PDF]

, 2016
During the first HyMeX Special Observation Period (SOP1) field campaign, the target site of north‐eastern Italy (NEI) experienced a large amount of precipitation, locally exceeding the climatological values and distributed among several heavy‐rainfall ...

Seasonal variation in community structure and elevational distributions of mammals and birds in the Central Himalayas

Ecography, EarlyView.
Montane species utilize various habitats along elevations to adapt to seasonality, providing an ideal opportunity to study how species respond to shifting environments. This study characterizes seasonal changes in community structure and elevational distributions across multiple taxa in the Central Himalayas.

Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

Energy Science &Engineering, EarlyView.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Estimating age of rock cairns in southeast Alaska by combining evidence from successional metrics, lichenometry, and carbon dating

Arctic Science, 2017
We estimated ages of rock cairns in alpine tundra in southeast Alaska by combining information from three general classes of methods, each of them imperfect, but considered together providing better estimates than any of the three alone.
