Recording fine-scale movement of ground beetles by two methods: Potentials and methodological pitfalls.

Ecol Evol 2021 Jul 16;11(13):8562-8572. Epub 2021 May 16.

MTA-ELTE-MTM Ecology Research Group Biological Institute, Eötvös Loránd University Budapest Hungary.

Movement trajectories are usually recorded as a sequence of discrete movement events described by two parameters: step length (distance) and turning angle (bearing). One of the most widespread methods to record the geocoordinates of each step is by a GPS device. Such devices have limited suitability for recording fine movements of species with low dispersal ability including flightless carabid beetles at small spatio-temporal scales. Read More

Climate change accelerates winter transmission of a zoonotic pathogen.

Ambio 2021 Jul 6. Epub 2021 Jul 6.

Swedish University of Agricultural Sciences, Skogsmarksgränd, 901 83, Umeå, Sweden.

Many zoonotic diseases are weather sensitive, raising concern how their distribution and outbreaks will be affected by climate change. At northern high latitudes, the effect of global warming on especially winter conditions is strong. By using long term monitoring data (1980-1986 and 2003-2013) from Northern Europe on temperature, precipitation, an endemic zoonotic pathogen (Puumala orthohantavirus, PUUV) and its reservoir host (the bank vole, Myodes glareolus), we show that early winters have become increasingly wet, with a knock-on effect on pathogen transmission in its reservoir host population.

Sensors (Basel) 2021 Jun 23;21(13). Epub 2021 Jun 23.

School of Earth and Planetary Sciences, Spatial Sciences, Curtin University, Perth 6102, Australia.

During the period 2019-2020, Lake Victoria water levels rose at an alarming rate that has caused various problems in the region. The influence of this phenomena on surface and subsurface water resources has not yet been investigated, largely due to lack of enough in situ measurements compounded by the spatial coverage of the lake's basin, incomplete/inconsistent hydrometeorological data, and unavailable governmental data. Within the framework of joint data assimilation into a land surface model from multi-mission satellite remote sensing, this study employs the state-of-art Gravity Recovery and Climate Experiment follow-on (GRACE-FO) time-variable terrestrial water storage (TWS), newly released ERA-5 reanalysis, and satellite radar altimetry products to understand the cause of the rise of Lake Victoria on the one hand, and the associated impacts of the rise on the total water storage compartments (surface and groundwater) triggered by the extreme climatic event on the other hand.
