Habitat-specific cues play an important role in orientation for animals that move through a mosaic of habitats. Environmental can be imprinted upon during early life stages to guide later return adult habitats, yet many species must orient toward suitable habitats without previous experience the habitat. It is hypothesized multiple sensory may enable differentiate between sequential order relevant spatial scales over which different types information are conveyed, but research, especially...
Abstract Given their positioning and biological productivity, estuaries have long represented key providers of ecosystem services consequently remain under remarkable pressure from numerous forms anthropogenic impact. The monitoring fish communities in space time is one the most widespread established approaches to assess ecological status other coastal habitats, but traditional surveys are invasive, costly, labour intensive highly selective. Recently, application metabarcoding techniques,...
The intensification of agriculture and livestock husbandry has led to increasing atmospheric deposition nitrogenous compounds soil acidification. We field measured extremely acidic soils with pH < 3 (i.e., the acidity domestic vinegar) over extensive areas forested national parks on sandy in Netherlands. These show stress from negative impacts increased forest health biodiversity. demonstrate that worsened an average approximately 4.5 current = 3.2 last 22 years for Natura 2000 Current...
Abstract Background The phyllosphere microbiome is crucial for plant health and ecosystem functioning. While host species play a determining role in shaping the microbiome, trees of same that are subjected to different environmental conditions can still exhibit large degrees variation their diversity composition. Whether these intra-specific variations composition be observed over broader expanse forest landscapes remains unclear. In this study, we aim assess top canopy bacterial communities...
A thorough understanding of ecological networks relies on comprehensive information trophic relationships among species. Since unpicking the diet many organisms is unattainable using traditional morphology-based approaches, application high-throughput sequencing methods represents a rapid and powerful way forward. Here, we assessed DNA metabarcoding with nearly universal primers for mitochondrial marker cytochrome c oxidase I in defining ecology adult brown shrimp, Crangon crangon, six...
Abstract Tropical peatlands are carbon-dense ecosystems that significant sources of atmospheric methane (CH 4 ). Recent work has demonstrated the importance trees as an emission pathway for CH from peat to atmosphere. However, there remain questions over processes production in these systems and how they relate substrate supply. Principally, relative contribution recent photosynthetically fixed carbon, released root exudates, versus carbon supply slowly decomposing matrix emissions within...
A combination of burrowing behaviour and very efficient background matching makes the brown shrimp Crangon crangon almost invisible to potential predators prey. This raises questions on how succeed in concealing themselves heterogeneous dynamic estuarine habitats they inhabit what type environmental variables behavioural factors affect their colour change abilities. Using a series experiments, we show that is capable repeated fast adaptations (20% dark pigment cover within one hour) its...
Abstract Aims The phyllosphere and soil are crucial distinct microbial spheres in forests, connected through trees that interact with both. As part of the tree's holobiont, these communities vital to fitness evolution host. Differences between may be particularly evident at two extreme ends tall long-lived natural temperate forest; top-canopy soil. Here, we evaluated connectivity European beech Norway spruce determine significance tree-sphere host-species identity, assess contribution taxa...
Forest canopies to some extent obscure passive reflectance of soil traits such as pH, well below-canopy vegetation, in the optical middle infrared portions electromagnetic spectrum (approximately 400–2500 nm) which are typically used airborne and spaceborne image spectrometers. In this study, we present, for first time, an accurate estimation pH across extensive areas using hyperspectral imaging data obtained from DLR Earth Sensing Imaging Spectrometer (DESIS) satellite. Furthermore,...
Despite a decrease in industrial nitrogen and sulfur deposition over recent decades, soil acidification remains persistent challenge to European forest health, especially regions of intense agriculture urbanisation. Using topsoil eDNA metabarcoding functional annotations from sample 49 plots (each 30 × m) located The Netherlands Germany, we investigated the effect severe on bacterial taxonomic diversity under different types explored potential implications for nutrient cycling.

Summary Correct characterization of heavy metal availability is a prerequisite for the management polluted soils. Our objective was to describe zinc (Zn) in soils by measuring isotopic exchangeability Zn soil/solution ( E value) and soil/plant systems L value), assessing transfer 65 fractions six‐step selective sequential extraction (SSE) incubated identifying forms means extended X‐ray absorption fine structure (EXAFS) spectroscopy. We distinguished three pools exchangeable Zn: pool within...
Models and approaches have been developed to predict radiation exposure of wildlife under field conditions. However, there few attempts directly measure in the confirm doses predicted by models. This is a potential issue for stakeholder acceptance modelling-based assessments. Here presented comprehensive study comparing results different dosimeters fitted free-ranging reindeer inhabiting an area that received comparatively high radiocaesium deposition from 1986 Chernobyl accident. The...
This experimental study focused on the possible deterrent effect of permanent magnets adult sandbar sharks Carcharhinus plumbeus. Results showed that presence a magnetic field significantly reduced number approaches conditioned C. plumbeus towards target indicating can be deterred by strong fields. These data, therefore, confirm use devices to reduce shark by-catch is promising avenue.
During six months in 1999, we observed the water vapor emission line at 183.31 GHz with a microwave radiometer high alpine site Jungfraujoch Switzerland. We retrieved statistics on atmospheric transmission and profiles of stratospheric selected days. Our seems well suited for observations this spectral line.
The study of animal colouration addresses fundamental and applied aspects relevant to a wide range fields, including behavioural ecology, environmental adaptation visual ecology. Although variety methods are available measure colours, only few focus on chromatophores (specialized cells containing pigments) pigment migration. Here, we illustrate freely user-friendly method quantify cover (PiC) with high precision low effort using digital images, where the foreground (i.e. pigments in...
Holothuria mammata is one of the new target species from Mediterranean and Atlantic.Usually, it inhabits rocky bottoms, staying in crevices holes during day leaving them night for feeding on sandy bottoms.However, can be found unusual habitats such as seagrass with diurnal nocturnal feeding.This study provides information first time behaviour, density small scale distribution H. a habitat Ria Formosa (S Portugal).To reach these aims, mark/recapture methodology was used.Abundance estimated...
Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them cope abundant but highly variable prey communities. The assessment of trophic relationships habitats is, however, challenging and often complicated by the bias low resolution analytical tools available study diet relatively small invertebrates. investigates niche overlap between two dominant epibenthic European environments, brown...
