Ground-nesting farmland birds such as the grey partridge (
Abstract The age at which individuals reproduce for the first time is a key demographic factor impacting population dynamics and subject to substantial variation across animal populations. There also widespread empirical evidence that of reproduction responds changes in density over time, especially long‐lived birds mammals. dependence has profound impacts on size non‐breeding (‘floater’) part population. A better understanding floater raptor populations urgently needed comprehensive...
We studied the nest site selection and distribution pattern at landscape level of German Osprey population, demonstrated how to test predictions ideal free theory its derivatives on such an expanding population. Information about location breeding success each between 1995 2005 was collected through a long-term monitoring programme. Data land cover types were acquired from administrations federal state CORINE Land Cover database. The results showed that Ospreys preferred landscapes with more...
Abstract Reduced food availability during chick raising is a major driver of farmland bird declines. For the Eurasian Skylark ( Alauda arvensis ), determined by various factors (i.e., arthropod abundance/diversity, accessibility vegetation, distance to foraging sites). In modern farmland, it supposed decrease over breeding season due less penetrable vegetation. We explored habitat selection chick‐raising Skylarks with focus on seasonal dynamics use and availability. investigated (i)...
Abstract Predation and habitat deterioration are the main reasons for strong decline of ground‐nesting farmland birds such as grey partridge Perdix perdix in Europe. Grey nests incubating females especially vulnerable to predation. We have previously demonstrated that predator activity is much lower inside flower blocks (agri‐environment schemes sown with a seed mix) than at their edges depends on surrounding landscape. Here, we investigate whether these differences translate into nest...
Abstract The lack of suitable nesting sites is one key driver behind the farmland bird crisis in Europe. Winter cereals become impenetrable for ground‐breeding birds like Eurasian Skylark ( Alauda arvensis ), curtailing breeding time. Stable populations depend on multiple attempts per year; thus, widespread cultivation winter has strongly contributed to their tremendous decline. Crop diversification thought be a potential measure counteract this development. Therefore, we explored how...
Intrinsic and extrinsic drivers shape the space use of wide‐ranging raptors. A large proportion raptors are migrants that shift their activity ranges between summer winter habitats, where they encounter different environmental conditions. Analysing effects intrinsic on in habitats provides crucial insights into ecology migratory Here, we investigated seasonal by 43 red kites Milvus milvus tracked GPS‐transmitters across central south‐western Europe over seven consecutive years. We compared...
The Mexican prairie dog Cynomys mexicanus is an endemic burrowing rodent with a restricted distribution. Up to 1996 the species experienced loss of c. 60% its historical range, and in last few years further habitat has occurred, current range now covering only 36% range. In this study we examined population dynamics determine relative effects loss, isolation remaining colonies, decreasing quality. We used data on numbers all colonies demographic for two carry out stochastic viability...
Abstract Linear structures in winter cereals like tramlines are frequently used but high-risk nesting sites for Eurasian Skylarks when crop vegetation becomes impenetrable during May. However, their influence on nest-site selection before greatly limits choice is less studied. Between 2017 and 2019, we located 32 nests the early breeding season show that nested 2 m further away from linear than expected if nest location was random. We interpret this avoidance as anti-predation behavior...
Abstract Background Biodiversity loss is particularly pronounced in agroecosystems. Agricultural fields cover about one-third of the European Union and are crucial habitats for many species. At same time, agricultural receive highest pesticide input landscapes. Non-target species, including plants arthropods, closely related to targeted pests, directly affected by pesticides. Direct effects on these lower trophic levels cascade through food web, resulting indirect via habitat subsequent...
Abstract High predation rates threaten many ground-nesting farmland birds and are difficult to address through conventional measures such as lethal predator control or fencing. Landscape-based approaches for conservation promise an alternative by reducing - bird encounters, but require detailed knowledge of landscape effects on risk. Different habitat elements attractive predators could have opposing neighbouring nesting habitats, with implications conservation: Increased risk due higher...
Many farmland birds such as the grey partridge Perdix perdix are experiencing sharp declines across Europe, which can lead to fragmentation and increasing isolation of local populations. Understanding population dynamics these populations is becoming increasingly important for effective conservation efforts. In this study, we used data from transect counts with call playback 2006 2023 investigate a in central Germany. We employed generalized linear mixed models model long‐term...
Auch im Landkreis Gottingen ist das Rebhuhn in den letzten Jahrzehnten stark zuruckgegangen. Das Rebhuhnschutzprojekt hat Ziel, Rebhuhnbestand langfristig anzuheben, um damit Risiko des lokalen Aussterbens zu reduzieren. Ca. 300-400 Rebhuhnpaare leben Landkreis. Seit 2005 werden rebhuhngerecht bewirtschaftete Bluhstreifen angebaut, 2007 waren ca. 1.000 solcher Flachen etabliert, insgesamt 540 Hektar. Alljahrliche Zahlungen Rebhuhnbestandes auf 90 km² haben Jahren nach einen deutlichen...
