Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

open access: yesIntegrative Conservation, EarlyView.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Pollenanalytical studies in NE-Nigeria: preliminary results from the Manga Grasslands and Lake Tilla, Biu Plateau [PDF]

open access: yes, 1996
Two sites situated in the Sahelian and Sudanian zones of NE-Nigeria were chosen for pollen analysis. A sediment core from an interdunal depression in the eastern Manga Grassland provides information on the Holocene vegetation history of the Sahel between

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

open access: yesInternational Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical

Spatio-temporal variation in pollen collected by honey bees (Apis mellifera) in rural-urban mosaic landscapes in Northern Europe.

open access: yesPLoS ONE
Pollen is a source of protein, lipids, vitamins and minerals for bees and other flower-visiting insects. The composition of macro- and micronutrients of pollen vary among different plant species.
