Abstract Point counts (PCs) are widely used in biodiversity surveys but, despite numerous advantages, simple PCs suffer from several problems: detectability, and therefore abundance, is unknown; systematic spatiotemporal variation detectability yields biased inferences, unknown survey area prevents formal density estimation scaling‐up to the landscape level. We introduce integrated distance sampling (IDS) models that combine (DS) with PC or detection/nondetection (DND) data capitalize on...
Summary Many animals and plant species have advanced spring phenology in response to climate warming. The majority of avian phenological studies are based on arrival dates. Consequently, knowledge bird is mainly migratory species. In addition, dates birds may be substantially affected by en route conditions, thus failing provide good indicators for the breeding grounds. Correlating with other data or environmental covariates meaningless these cases. We propose date highest singing activity,...
The population dynamics of urban animals has been so far remarkably understudied. At the same time, species' trends can provide important information on consequences environmental changes in cities. We modelled long-term 93 bird species breeding areas 16 European countries as a function traits, characterising variability their urbanization and ecology. found that: (i) earlier colonisers have more negative than recent colonisers; (ii) urbanized open habitat had positive less species; (iii)...
Climate warming is driving changes in species distributions and community composition. Many have a so-called climatic debt, that is, shifts range lag behind temperature isoclines. Inside protected areas (PAs), response to climate can be facilitated by greater colonization rates warm-dwelling species, but also mitigated lowering extirpation of cold-dwelling species. An evaluation the relative importance colonization-extirpation processes important inform conservation strategies aim for both...
Abstract Aim In biodiversity monitoring, observational data are often collected in multiple, disparate schemes with greatly varying degrees of standardization and possibly at different spatial temporal scales. Technical advances also change the type over time. The resulting heterogeneous datasets deemed to be incompatible. Consequently, many available may ignored practical analyses. Here, we propose a more efficient use assess species distributions population trends. Location Switzerland...
As a response to climate warming, many animals and plants have been found shift phenologies, such as appearance in spring or timing of reproduction. However, traditional measures for shifts phenology that are based on observational data likely biased due large influence population size, effort, starting date survey, other causes may affect the probability detecting species. Understanding phenological responses species change, however, requires robust measure could be compared among studies...
Abstract Many studies in ecology and management aim at quantifying absolute abundance based on counts a set of surveyed sites. As time for data collection is typically limited, methods reliable estimation occupancy or from low‐cost are desirable. Time‐to‐detection (TTD) models have shown promise the occupancy. However, they remain heavily underutilized, restricted to inference about occupancy, rather than abundance. We developed binomial N‐mixture model species‐level TTD protocols that...
Multi-species indices (MSI) are widely used as ecological indicators and instruments to inform environmental policies. Many of these combine species-specific estimates relative population sizes using the geometric mean. Because mean is not defined when values zero occur, usually only commoner species included in MSIs replaced by a small non-zero value. The latter can exhibit an arbitrary influence on MSI. Here, we show how compound Poisson negative binomial model be such cases obtain MSI...
Capsule:We used data from different sources, developed and applied several estimation methods, confronted the resulting estimates with species experts to achieve breeding size population for all bird currently in Switzerland.Aims:Population of birds have a wide range practical conservation uses. As part Swiss Breeding Bird Atlas 2013–2016, we aimed update national species.Methods:For very rare colonial breeders, are complete enumerations based on annual compilations records. For other...
<title>Abstract</title> Human pressures, particularly urbanisation and agricultural expansion, profoundly affect biodiversity by reshaping species functional trait distributions, with critical consequences for ecosystem resilience multifunctionality. Yet, the extent strength of these impacts across diverse taxa ecosystems remain poorly understood. Here, we analyse 160 spatial datasets, encompassing over 13,000 local communities nine major in freshwater terrestrial worldwide. Our results...
Abstract Climate warming is driving changes in species distributions, although many show a so-called climatic debt, where their range shifts lag behind the fast shift temperature isoclines. Protected areas (PAs) may impact rate of distribution both positively and negatively. At cold edges PAs can facilitate by increasing colonization required for change. warm edges, mitigate loss species, reducing local extinction vulnerable species. To assess importance to affect change, we evaluated...
Abstract Drug delivery into articular cartilage poses many challenges due in part to its lack of vasculature. While intra‐articular injections are effective for the local administration drugs, small molecules rapidly cleared from synovial fluid. As such, there is a need develop drug strategies improve residence times bioactive joint and elicit sustained therapeutic effect. In this study, calcium‐ strontium‐polyphosphate particles synthesized characterized as potential carriers cartilage....
Die Entwicklung der Verbreitung Schweizer Brutvögel ist ein Spiegelbild unseres Umgangs mit Natur und Umwelt. Mit dem Brutvogelatlas 2013-2016 wurden die aktuellen Vorkommen, Häufigkeit Höhenverbreitung aller Schweiz des Fürstentums Liechtenstein dokumentiert. Zusammen den drei früheren Brutvogelatlanten lassen sich damit Veränderungen in Vogelwelt letzten 20 bis 60 Jahren aufzeigen. So weist, im Vergleich zu anderen Lebensraumgilden, Bestandsindex Waldvögel positivsten Verlauf auf. Trotzdem...
