The Impact of Dealiasing Biases on Bird and Insect Data Products of C-Band Weather Radars and Consequences for Aeroecological Applications

Remote Sensing
(1) The aliasing of radial velocities from weather radars is a known challenge in meteorology. It may also occur during bird migration if the unambiguous velocity threshold is below the birds’ ground speed.

VAGRANCY RECORDS OF THE GREAT WHITE PELICAN PELECANUSONOCROTALUSLINNAEUS, 1758 (AVES, PELECANIFORMES, PELECANIDAE) IN SOUTHERN INDIA

Bulletin of the Iraq Natural History Museum
Vagrancy is a less contrived part in the context of bird migration; thus, observing the vagrancy pattern of immigrants helps to discover changes in distribution, range shifting, and range expansion of the bird species.

Annual and Seasonal Rainfall Variability in Mozambique During the Nineteenth Century

International Journal of Climatology, EarlyView.
This paper presents the first annually and seasonally resolved reconstructions of nineteenth‐century rainfall variability for Mozambique derived from the analysis of extensive documentary evidence. It reveals spatially heterogeneous rainfall patterns with recurrent multi‐year droughts, episodic extreme wet events, and a strong coherence between ...

First report on the soil seed bank damage due to fire at the Rohingya refugee camps in Bangladesh

JSFA reports, EarlyView.
Abstract Background The composition, density, and damage of the soil seed bank were studied at Kutupalong Rohingya refugee camp (the world's largest refugee settlement), Ukhiya, Cox's Bazar, Bangladesh, after a major human‐induced fire on March 22, 2021, causing huge damage to human lives, settlements, and the ecosystem.

Burrow use by Saharan striped polecat (Poecilictis libyca) in an agricultural area of central Tunisia

The Journal of Wildlife Management, EarlyView.
Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.

Recovery of great blue herons (Ardea herodias) within the Chesapeake Bay

The Journal of Wildlife Management, EarlyView.
We surveyed great blue herons throughout the tidal reach of the Chesapeake Bay in 2013 and mapped 423 colonies supporting 15,094 pairs. The population has increased more than four‐fold since the mid‐1970s. Colony size has declined. Invasion of colonies by bald eagles may be driving a change in spatial structure.

The Swedish Arctic Fox Project: 40 years of research in ecology and conservation

The Journal of Wildlife Management, EarlyView.
The 4 central research themes in The Swedish Arctic Fox Project and key deliverables for practical conservation achieved over 4 decades. Abstract The scientific community widely recognizes the value of long‐term studies, especially those with individual‐level resolution; however, maintaining a consecutive data series is associated with multiple ...

White light reduces flight height of birds in low‐density migration corridor

The Journal of Wildlife Management, EarlyView.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.
