Abstract Forests are under pressure and going through rapid changes. However, current inventorying monitoring (IM) programs often either disjointed, too narrow in their scope and/or do not operate at fine enough temporal resolutions, which may hinder scientific understanding, the timely supply of information, fast decision making, result sub-optimal use resources. For these reasons, there is an urgent need for Advanced Forest Inventorying Monitoring (AIM) to (i) achieve expanded relevance...
Success stories are rare in conservation science, hindered also by the research-implementation gap, where scientific insights rarely inform practice and practical implementation is evaluated scientifically. Amphibian population declines, driven multiple stressors, emblematic of freshwater biodiversity crisis. Habitat creation a straightforward action that has been shown to locally benefit amphibians, as well other taxa, but does it entire amphibian communities at large spatial scales? Here,...
Abstract The success of ponds constructed to restore ecological infrastructure for pond‐breeding amphibians and benefit aquatic biodiversity depends on where how they are built. We studied effects pond landscape characteristics, including connectivity, metapopulation dynamics 12 amphibian species in Switzerland. To understand the determinants long‐term occupancy (here summarized as incidence), environmental both colonization persistence should be considered. fitted dynamic models 20 years...
ABSTRACT Research about fertility has focused in the main on studying separately influence of communication networks and social capital reproductive behavior, but it rarely tried to integrate both network properties theoretically or analytically. We therefore discuss a general model purposeful behavior that perceives individuals' subjective perceptions utilities different courses action be affected by structures interpersonal influence. Resources needed realize desired goals are furthermore...
Reliable assessments of population status and trends underpin conservation management efforts but are complicated by the fact that imperfect detection is ubiquitous in monitoring data. We explore most commonly considered variables believed to influence probabilities, quantifying how they detectability assessing occupancy rates impacted when a variable ignored. To do so, we used data from two multi-species amphibian programmes, collected volunteers professional surveyors. Our results suggest...
The marsh frog (Pelophylax ridibundus s.l.) is the number one amphibian invader in Western Europe. In Switzerland, frogs were introduced 1950–1960s and progressively colonized most of northern parts country. We investigated this invasion using molecular tools. mapped cryptic presence three monophyletic mitochondrial lineages (P. ridibundus, Pelophylax kurtmuelleri, cf. bedriagae from southeastern Europe) consistent with registered importations by a local frog-leg industry. High nuclear...
Summary Environmental change and land use may alter the vegetation typical of wetland habitats. However, commonly used techniques for monitoring that are based on species composition often not suitable to detect gradual changes in structure at an early stage. In this study we tested if methodical deficiency could be overcome by observation stage a perennial target species. We studied density frequency distribution four phenological stages plant Succisa pratensis 24 calcareous fens eastern...
Abstract: Acute liver failure after hepatic surgery is still plaqued with high mortality rate. Recently, a dialysis system (MARS®) that allows detoxification of albumin‐bound substances and may hereby support regeneration patient's recovery has been developed. In the present study, we report our experiences MARS® in patients resection or transplantation. Between September 1999 January 2001, five were treated (2–5 courses). Though beneficial effects such as improvement encephalopathy renal...

Abstract Data collected by volunteers are an important source of information used in species management decisions, yet concerns often raised over the quality such data. Two major forms error exist occupancy datasets; failing to observe a when present (imperfect detection—also known as false negatives), and falsely reporting (false‐positive errors). Estimating these rates allows us quantify volunteer data quality, may prevent inference erroneous trends. We use new parameterization dynamic...
Clinical islet allotransplantation has become an increasingly efficient “routine ” therapy in recent years. Shortage of human donor organs leads to porcine pancreatic islets as a potential source for xenotransplantation. Yet it is still very difficult isolate sufficient numbers intact islets, particularly from young market pigs. In the following study were successfully isolated retired breeders [4806 ± 720 equivalents per gram organ (IEQ/g); n = 25; 2–3 years old; RB] and also hybrid pigs...

Despite the many differences that exist between Italy, Bulgaria, and Germany, threecountries are among those with lowest fertility rates in Europe. However, they differ inthe level of public support for families role informal supportive networks indaily life. Italy on one hand, share very low levels support. Inboth countries, consequently, based family relationshipsand kinship have a strong tradition high relevance getting things done. InGermany, however, by policy is much stronger...

To study the consequences newly established species interactions, one available source data could be observational surveys from biodiversity monitoring. However, approaches using would need account for niche differences between and imperfect detection individuals. estimate population sizes species, we extended N-mixture models that were developed true in single...
