Abstract Alien plants have generally been shown to support reduced arthropod abundance, biomass, and diversity compared to native plant species, but inferences have typically come from studies limited in taxonomic and geographic scope. Here, we make use of data from a unique citizen science project, Caterpillars Count!, that consists of nearly 70,000 ...

A Research on Stem Sap Flow Dynamics of Ulmus Pumila in Mu Us Sandy Area,Yanchi County
The EC-SF Sap Flow Measuring System were applied to study the diurnal changes of stem sap flows for Ulmus pumila based on the thermal dissipation theory.At the same time,the circumstance factors around the Ulmus pumila were recorded by radiation,air ...

This study employed integrated analyses of chloroplast DNA and nuclear genes, which revealed significant divergence in genetic structure between the two genomic compartments in Xinjiang wild apricots, reflecting complex evolutionary processes influenced by natural selection, genetic drift, and gene flow. Population history analyses indicated an absence

Groundwater‐dependent native riparian ecosystems of the Gila River floodplain (a) near the upstream end of the valley in winter 2014 and (b) near the downstream valley end in summer 2018. Topographically complex floodplains create favourable conditions across the full breadth of the valley bottom for a diversity of native groundwater‐dependent ...

Стан iнвазiйностi Ulmus pumila L. в урбоекосистемi за клiматичних змiн
Клiматичнi змiни здатнi впливати на межi поширення природних i адвентивних видiв рослин. Коливання температури повiтря, вiдносної вологостi та iнших факторiв можуть стати стимулом для iнiцiацiї та/або iнтенсифiкацiї iнвазiйної природи деяких адвентивних

Using the most complete summary of 20 years of riparian plant water use studies in North American drylands to date, we examine broad patterns of plant water use by vegetation type and across climate gradients. Marshes, cottonwood‐willow stands and tamarisk use larger amounts of water than other communities, and all communities have higher water use in ...

Experimental methods for wind tunnel studies of seed dispersal by wind
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...
