Accounting for detection probability when estimating force-of-infection from animal encounter data
Journal of Ornithology - Tập 152 Số S2 - Trang 511-520 - 2012
Die Veränderung der Brutvogelfauna in zwei süddeutschen Dorfgemeindebereichen in den letzten fünf bzw. drei Jahrzehnten oder: verlorene Paradiese?
Journal of Ornithology - Tập 144 - Trang 385-410 - 2003
Für zwei süddeutsche Dorfgemeindebereiche (Möggingen — Sitz der Vogelwarte Radolfzell — und Billafingen — Wohnort des Autors, beide in der Nähe des Bodensees) lassen sich aufgrund von kontinuierlichen Beobachtungen, wiederholten Bestandserfassungen, Tagebuchaufzeichnungen und u. a. die Veränderungen der Avifauna für 5 bzw. 3 Jahrzehnte darstellen, für Möggingen auch detailliert quantitativ. Die Er...... hiện toàn bộ
Ecological and historical views of the diversification of Geositta miners (Aves: Furnariidae: Sclerurinae)
Journal of Ornithology - Tập 158 - Trang 15-23 - 2016
Diverse historical and ecological factors determine and drive diversification of vertebrate lineages. Historical factors (e.g., orogenic movements) are expected to act on coarser spatial and temporal scales than contemporary ecological factors (e.g., climate and biotic interactions). However, distinctions between such scales remain arbitrary, and yet are important to understanding which factors ac...... hiện toàn bộ
Genetic monogamy in the Common Crossbill (Loxia curvirostra)

Nestling diet optimization and condition in relation to prey attributes and breeding patch size in a patch-resident insectivorous passerine: an optimal continuum and habitat constraints
Journal of Ornithology - Tập 158 - Trang 169-184 - 2016
Direct observational studies are needed to address dietary adjustment in species breeding in isolated non-forest habitat islands with respect to the energy demands of growing nestlings and breeding patch size. Using new dietary records determined for nestlings of Whinchat Saxicola rubetra, a dramatically declining insectivorous passerine and an indicator species of the cessation of agricultural ac...... hiện toàn bộ
Autumn migratory departure is influenced by reproductive timing and weather in an Arctic passerine
Journal of Ornithology - Tập 161 - Trang 779-791 - 2020
Numerous studies of spring migration have discovered that environmental conditions experienced on the wintering grounds and/or during vernal migration itself can have “carry-over effects” altering timing or success of the subsequent breeding season. Few studies have evaluated whether breeding and pre-basic molt have carry-over effects on autumn migration. The aim of this study was to test the expe...... hiện toàn bộ
The earliest known pelican reveals 30 million years of evolutionary stasis in beak morphology
Journal of Ornithology - Tập 152 - Trang 15-20 - 2010
The feeding apparatus of Paleogene birds is rarely well-preserved. Here, we describe the earliest known pelican (early Oligocene, Luberon, southeastern France), with its almost complete beak. Morphologically identical to modern pelicans, the new fossil already shows several advanced features unique to extant species of the genus Pelecanus. It probably belongs to the lineage ancestral to all or som...... hiện toàn bộ
