Abstract 1. To be effective, the next generation of conservation practitioners and managers need to critical thinkers with a deep understanding how make evidence‐based decisions value evidence synthesis. 2. If, as educators, we do not these priorities core part what teach, are failing prepare our students an effective contribution practice. 3. help overcome this problem have created open access online teaching materials in multiple languages that stored Applied Ecology Resources. So far, 117...
Dried plant specimens stored in herbaria are an untapped treasure chest of information on environmental conditions, evolution and change over many hundreds years. Owing to their delicate nature irreplaceability, there is limited access for analysis these sensitive samples, particularly where chemical data obtained using destructive techniques. Fourier transform infrared (FTIR) spectroscopy a technique which can be applied non-destructively understand bonding and, therefore, functional groups...
Summary Grazing mammals are often used to maintain and restore high conservation value plant communities, but the evidence base for management is lacking long‐term studies. We erected grazing exclosures in dune slacks determine impact of three different regimes on community: (1) rabbits sheep excluded 36 years, (2) continued rabbit years (3) 17 followed by 19 years. monitored community composition inside outside exclosures. All communities changed over time, moving away from original...
Summary Sedimentation and clogging of benthic hyporheic zone substrata is increasingly being recognised as one the greatest threats to ecological integrity riverine ecosystems globally. This ex situ study examined influence sedimentation (surface subsurface) pattern hydrological exchange on vertical distribution freshwater shrimp Gammarus pulex within experimental running water mesocosms. Six sediment treatments representing a continuum from clean gravel substratum heavy loading both surface...
Abstract Streambed drying is becoming more common due to climate change and increasing anthropogenic water resource pressures. Subsurface sediments are a potential refuge for benthic macroinvertebrates during events in temporary streams. Sediment characteristics important controls on the distribution of subsurface habitats, but difficulties making observations impedes quantification vertical movements. Species traits (e.g. habitat affinity) also influence movements into sediments, most...
The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour also function as camouflage, preventing avoidance. We tested these two hypotheses situ for the plant Drosera rotundifolia . conducted three separate studies: (i) artificial isolate influence colour; (ii) on backgrounds control degree contrast and (iii) observation capture by D. determine effects capture. Prey were not attracted green deterred from traps. There...
Abstract Flume studies have demonstrated that foraging by fish can modify the structure and topography of gravel substrates, thereby increasing particle entrainment probabilities amount sediment mobilized during subsequent experimental high flows. However, zoogeomorphic impact benthic has not previously been investigated in field. This paper reports field experiments examined nature extent disturbance riverbed gravels fish, predominately Cyprinids, at patch, riffle, reach scales...
Summary Carnivory in plants is presumed to be an adaptation a low‐nutrient environment. Nitrogen (N) from carnivory expected become less important component of the N budget as root availability increases. Here, we investigated uptake via roots versus prey carnivorous plant Drosera rotundifolia growing ombrotrophic bogs along latitudinal deposition gradient through Sweden, using natural abundance stable isotope mass balance technique. receiving lowest level obtained greater proportion (57%)...
Intermittent rivers, which experience periods of flow cessation and streambed drying, occur globally. Given that the frequency duration stream drying events is likely to increase as a result anthropogenic pressures global climate change, riverbed sediments may become increasingly important refuge habitat for benthic macroinvertebrates. Our study examined effect surface water loss increasing on survivorship most abundant invertebrate, Gammarus pulex (L.) (Amphipoda: Gammaridae), inhabiting...
• The contribution of insect prey to total N in the carnivorous plants, Drosera rotundifolia and D. intermedia, was quantified situ without any experimental manipulation using natural abundance stable isotope analysis. Samples insects noncarnivorous reference plants were collected from three contrasting locations across Britain. proportion nitrogen obtained calculated by a mixing model δ15N values different plant groups. mean derived 50%. There significant differences this between sites,...
Summary Deciduous trees recycle nitrogen within their tissues. The aim of this study was to test the hypothesis that reductions in plant growth, caused by competition and herbivory, reduce sink strength for N during autumn nutrient withdrawal, storage capacity hence amount remobilized following spring. We used 15 N‐labelled fertilizer quantify uptake, leaf withdrawal remobilization. Betula pubescens saplings were grown with either Molinia caerulea or Calluna vulgaris , subjected simulated...
Abstract Aim To identify geographic patterns in leaf colour of roundleaved sundew ( Drosera rotundifolia ) growing on ombrotrophic (rain fed) bogs across Europe and establish the controls over these patterns.

Methods We measured D. plants 24 north‐west covering 26.4 degrees longitude 21.1 latitude. height cover co‐occurring vascular plant vegetation amount incident light intercepted by canopy. determined role abiotic variables controlling...
Ellenberg indicator values for plant species are widely used metrics in ecology, providing a proxy measure of environmental conditions, without direct measurements. They integrate conditions over time since will only persist where favourable. moisture (F) summarise the hydrological environment experienced by plants. However, relationship between and appears to be influenced range other abiotic biotic factors, limiting our ability fully interpret F. Focussing on F, we evaluated how unweighted...
Abstract Leaves of the carnivorous sundew plants ( Drosera spp.) secrete mucilage that hosts microorganisms, but whether this microbiota contributes to prey digestion is unclear. We identified acidophilic fungus Acrodontium crateriforme as dominant species in microbial communities, thriving multiple across global range. The grows and sporulates on glands its preferred acidic environment, presence traps increased process. A. has a reduced genome similar other symbiotic fungi. During –...
Geomorphic resilience is the capacity of a system to recover pre-disturbance conditions following perturbation. The 2013/14 Atlantic winter storm period had extensive geomorphological impacts and provides an opportunity assess coastline resilience. This paper uses high spatio-temporal resolution data quantify beach-dune response subsequent recovery prograding 5 December 2013 North Sea surge. It demonstrates that despite water levels destructive nature storm, recovered sediment rapidly over...
Carnivorous plants are sensitive to small changes in resource availability, but few previous studies have examined how differences nutrient and prey availability affect investment the benefit of carnivory. We studied impact site-level on ecophysiological traits carnivory for Drosera rotundifolia L.We measured (leaf stickiness), capture diet growing two bogs with N deposition plant available N: Cors Fochno (0.62 g m-2 yr.-1, 353 μg l-1), Whixall Moss (1.37 1505 l-1). The total amount per...
Secondary metabolites are integral to multiple key plant processes (growth regulation, pollinator attraction and interactions with conspecifics, competitors symbionts) yet their role in adaptation remains an underexplored area of research. Carnivorous plants use secondary acquire nutrients from prey, but the extent carnivory is not known. We aimed determine facilitating Cape sundew, Drosera capensis.We conducted metabolomic analysis 72 a time-series experiment before after simulated prey...
Abstract Questions Hydrological niche segregation is widespread and has been found across a range of different habitats. Different plant species can occupy distinct hydrological niches, as result fine‐scale variability in hydrology structure communities. However, these patterns may not be clear habitats where differences are more short‐lived, such coastal dune slacks. We explored the extent that regime structures slack Location Ainsdale Coastal Sand Dune National Nature Reserve, UK. Methods...
