Urban edge trees: Urban form and meteorology drive elemental carbon deposition to canopies and soils

Article asserts that urban tree canopies are a significant sink for atmospheric elemental carbon (EC)--and air pollutant that is a powerful climate-forcing agent and threat to human health. The authors' findings indicate that complex configurations of roads, buildings, and vegetation produce “urban edge trees” that contribute to heterogeneous EC deposition patterns across urban systems, with implications for greenspace planning.

Object-Oriented Canopy Gap Extraction from UAV Images Based on Edge Enhancement (open access)

Object-Oriented Canopy Gap Extraction from UAV Images Based on Edge Enhancement

Article describes the efficient and accurate identification of canopy gaps is the basis of forest ecosystem research, which is of great significance to further forest monitoring and management. One major limitation of the traditional methods of remote sensing to map canopy gaps is that they cannot finely extract the complex edges of canopy gaps in mountainous areas. The authors proposed an object-oriented classification method that integrates multi-source information.

Estimating landscape structure effects on pollination for management of agricultural landscapes (open access)

Estimating landscape structure effects on pollination for management of agricultural landscapes

Article estimating the effects of different scenarios of forest fragmentation to find an optimized pattern of forest patches for increasing pollination in an agricultural landscape. The authors use simulated agricultural landscapes and landscape metrics to estimate the relationship between pollination and landscape structure.
