Disentangling the spatial and temporal causes of decline in a bird population

Ecology and Evolution, 2020
The difficulties in understanding the underlying reasons of a population decline lie in the typical short duration of field studies, the often too small size already reached by a declining population or the multitude of environmental factors that may ...

Effects of Chemical and Auditory Cues of Hoopoes (Upupa epops) in Repellence and Attraction of Blood-Feeding Flies

Frontiers in Ecology and Evolution, 2020
Research on the mechanisms involved in host location by parasites is of paramount importance and may aid in developing protective measures against them.

Function of song in the HoopoeUpupa epops [PDF]

Bird Study, 1999
Male Hoopoes Upupa epops, (Coraciformes) have a very simple song, with a repertoire size of one. The number of elements per strophe (strophe length) is the only difference between strophes of the same male, and the main difference between males. The function of this song was analysed in a colour-ringed population of Hoopoes in Granada, southern Spain ...

Massive nest-box supplementation boosts fecundity, survival and even immigration without altering mating and reproductive behaviour in a rapidly recovered bird population. [PDF]

PLoS ONE, 2012
Habitat restoration measures may result in artificially high breeding density, for instance when nest-boxes saturate the environment, which can negatively impact species' demography.

Gut microbiota variation and trophic niche differentiation among sympatric birds in a forest-farmland mosaic

Global Ecology and Conservation
The abundance and diversity of gut microbiota influence avian health, nutrient assimilation, and overall physiological performance. However, the extent to which variation in gut microbial composition corresponds to resource use and niche differenśtiation

Chlamydia species in free-living Cattle Egret (Bubulcus ibis) and Hoopoe (Upupa epops) in Egypt

International Journal of Veterinary Science and Medicine, 2014
Little information is available on the presence of chlamydia infection in wildlife. This study was conducted to assess the occurrence of chlamydiae in asymptomatic birds from two species of wild birds (Cattle Egret and Hoopoe) in Egypt.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Geolocation with a magnetic sensor

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2395-2407, August 2026.
Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which

Application of a novel molecular diagnostic method to examine the spatio‐temporal trends of Carcelia iliaca, a larval parasitoid of oak processionary moth (Thaumetopoea processionea)

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 348-356, August 2026.
The oak processionary moth is an invasive pest in the United Kingdom that threatens biodiversity and public health, with rising control costs highlighting the need for sustainable management alternatives Conservation biocontrol using the parasitoid fly Carcelia iliaca is promising but key biological data gaps hinder evidence‐based policy development. A

Wetland birds of middle Vistula River during breeding season: the impact of human activities on the distribution, abundance and richness of species

Studia Ecologiae et Bioethicae, 2020
The inventory of birds was conducted in the years 2005-2010 on the Vistula River section between Dęblin (km 388 of the river) and Podwierzbie (km 435 of the river). The study area includes a southern section of the European Ecological Natura 2000 Site in
