Data from: Estimating sensitivity of seabed habitats to disturbance by bottom trawling based on the longevity of benthic fauna
Bottom fishing such as trawling and dredging may pose serious risks to the seabed and benthic habitats, calling for a quantitative assessment method to evaluate the impact and guide management to develop mitigation measures. We provide a method to estimate the sensitivity of benthic habitats based on the longevity composition of the invertebrate community. We hypothesize that long-lived species are more sensitive to trawling mortality due to their lower pace of life (i.e. slower growth, late maturation). We analyse data from box-core and grab samples taken from 401 stations in the English Channel and southern North Sea to estimate the habitat-specific longevity composition of the benthic invertebrate community and of specific functional groups (i.e. suspension feeders and bioturbators), and examine how bottom trawling affects the longevity biomass composition. The longevity biomass composition differed between habitats governed by differences in sediment composition (gravel and mud content) and tidal bed-shear stress. The biomass proportion of long-lived species increased with gravel content and decreased with mud content and shear stress. Bioturbators had a higher median longevity than suspension feeders. Trawling, in particular by gears that penetrate the seabed >2cm, shifted the community towards shorter-lived species. Changes from bottom trawling were highest in habitats with many long-lived species (hence increasing with gravel content, decreasing with mud content). Benthic communities in high shear stress habitats were less affected by bottom trawling. Using these relationships, we predicted the sensitivity of the benthic community from bottom trawling impact at large spatial scale (the North Sea). We derived different benthic sensitivity metrics that provide a basis to estimate indicators of trawling impact on a continuous scale for the total community and specific functional groups. In combination with high resolution data of trawling pressure, our approach can be used to monitor and assess trawling impact and seabed status at the scale of the region or broadscale habitat and to compare the environmental impact of bottom-contacting fishing gears across fisheries.
Data from: Fish in habitats with higher motorboat disturbance show reduced sensitivity to motorboat noise
Anthropogenic noise can negatively impact many taxa worldwide. It is possible that in noisy, high-disturbance environments the range and severity of impacts could diminish over time, but the influence of previous disturbance remains untested in natural conditions. This study demonstrates effects of motorboat noise on the physiology of an endemic cichlid fish in Lake Malaŵi. Exposure to motorboats driven 20–100 m from fish and loudspeaker-playback of motorboat noise both elevated oxygen-consumption rate at a single lower-disturbance site, characterised by low historic and current motorboat activity. Repeating this assay at further lower-disturbance sites revealed a consistent effect of elevated oxygen consumption in response to motorboat disturbance. However, when similar trials were repeated at four higher-disturbance sites, no effect of motorboat exposure was detected. These results demonstrate that disturbance history can affect local population responses to noise. Action regarding noise pollution should consider the past, as well as the present, when planning for the future.

Habitat availability alters the relative risk of a bovine tuberculosis breakdown in the aftermath of a commercial forest clearfell disturbance
<p><span></span></p> <p>1. Human modification of landscapes and associated disturbances may facilitate the emergence and spread of zoonotic diseases. Policy-makers need better understanding of the link between anthropogenic disturbances and wildlife disease hosts at the interface of human society and the natural environment, e.g. agriculture, forestry and aquaculture. Empirical research is strongly needed for the control of novel zoonoses which might emerge, as well as the management of existing zoonoses with significant economic repercussions such as bovine tuberculosis (bTB).</p> <p>2. We aimed to examine the link between ecological disturbance and relative bTB risk using Ireland as a case study. We analysed clearfell forestry operations and assessed bTB breakdowns within cattle farms across different spatio-temporal scales over multiple years, examining how ecological conditions may modulate this relationship using conditional logistic regression models.</p> <p>3. We found a significant effect of the interaction between the extent of clearfell forestry removed and the extent of natural grassland and mixed forestry present on relative bTB risk. This interaction was dynamic, leading to an increase or decrease of the relative bTB risk depending on where (between 2 and 6 km from the farm) and when (between 0 and 36 months prior to the bTB outbreak) the clearfell operations occurred.</p> <p>4. Our study provides empirical evidence of the link between mechanised forestry operations and fluctuating relative bTB risk in cattle farms, although the mechanism behind it is yet to be elucidated. Given our data, we hypothesise that wildlife hosts may abandon the area subjected to clearfell when disturbance is highest (during active operations and shortly afterward) but are subsequently attracted back to the site as they regenerate, potentially affecting the contact rates with livestock and thus, relative bTB risk.</p> <p>5. Our analysis demonstrates that landscape modification is correlated with a change in relative bTB risk that is dynamic in time and space, allowing managers to understand the risk in landscape modification and inform policy accordingly. Landscape-level studies are necessary to unveil subtle ecological processes, shifting research and management efforts away from cattle herd-centric and toward macroecological surveillance of wildlife hosts and longitudinal assessment of bTB risk.</p>

Habitat use of Amazonian birds varies by age and foraging guild along a disturbance gradient
<p>Patterns of habitat use directly influence a species' fitness, yet for many species an individual's age can influence patterns of habitat use. However, in tropical rainforests, which host the greatest terrestrial species diversity, little is known about how age classes of different species use different adjacent habitats of varying quality. We use long term mistnet data from the Amazon rainforest to assess patterns of habitat use among adult, adolescent (teenage), and young understory birds in forest fragments, primary, and secondary forest at the Biological Dynamics of Forest Fragments Project in Brazil. Insectivore adults were most common in primary forest, adolescents were equally likely in primary and secondary forest, and all ages were the least common in forest fragments. In contrast to insectivores, frugivores and omnivores showed no differences among all three habitat types. Our results illustrate potential ideal despotic distributions among breeding populations of some guilds of understory birds where adult insectivores may competitively exclude adolescent individuals from primary forest. Secondary forest recovery appears to hold promise as breeding habitat for frugivore and omnivore species but only as pre-breeding habitat for insectivores, but as the forest ages, the demographic structure of bird populations should match that of primary forest.</p>

Data from: Influence of habitat availability and fire disturbance on the northern range boundary of eastern white cedar (Thuja occidentalis L.)
Aim <p>Non-climatic constraints on species northern range boundaries are often overlooked in attempts to predict climate-induced range shifts. Here, we examined the effects of habitat availability and fire disturbance on the distribution of eastern white cedar (<i>Thuja occidentalis</i> L.) at the northern boundary of its range.</p> Location <p>North-western Quebec, Canada (46-51° N and 74-79° W)</p> Methods <p>We used forest inventory data (<i>n</i>=4,987) to characterize white-cedar habitat based on edaphic and topographic conditions at sampled sites along a 600-km latitudinal gradient. Non-metric multidimensional scaling was used to assess habitat similarity of sites in the south, where white-cedar stands are abundant, and sites in the north, where white-cedar stands are rare. We constructed ensemble white cedar distribution models based on habitat variables in the south and compared ensemble forecast projections of white cedar in the north with observed occurrences to determine if habitat availability was limiting. We independently estimated the age of white-cedar stands and adjacent stands without white cedar along the gradient. ANOVA was performed to test the age difference between white-cedar and adjacent stands to determine if the location of white-cedar stands was influenced by disturbance, primarily stand-replacing fire.</p> Results <p>Habitat availability was not limiting the distribution of eastern white cedar at its northern range boundary. White cedar did not occupy most sites with suitable habitat in the north, suggesting that other factors prevent white cedar from establishing more stands northward. White-cedar stands were older than adjacent stands without white cedar all along the gradient, but the difference was more pronounced in the north. This suggests that white-cedar stands in the north are restricted to undisturbed areas.</p> Main conclusions <p>Fire disturbance, more than habitat availability, limits the distribution of white cedar at its northern range boundary. Projections of white cedar distribution under climate change that ignore fire could overestimate the ability of warming temperatures to extend its northern range limit.</p>
Lena Delta habitat disturbance regimes
<p>In the Lena Delta, mainly annual flooding, but also local rapid thaw processes on the land surface of the terraces with ice-rich permafrost, result in disturbance regimes forming distinct habitat types. The floodplains experience seasonal flooding as a regularly occurring disturbance in spring after ice-break up (the spring flood). Very high disturbance regimes due to the most intense scour, erosion and sedimentation result in barren sandbanks or in early-stage plant communities equalling the ‘sparsely vegetated’ habitat class. ‘moist to wet sedge communities’<em>, ‘</em>wet sedge communities’<em>, ‘</em>moist equisetum and shrubs’<em>, ‘</em>dry shrub communities’<em>, ‘</em>dry grass to wet sedge communities’ forms the mid to advanced successional stages on the floodplain (high disturbance regime) with shifting habitat types according to Stanford et al., (2005) and Driscoll and Hauer, (2019).</p> <p>In contrast to the floodplain, habitats on the first, second and third delta terraces are less extensively disturbed (low disturbance) allowing the development of the typical mature-state tundra plant communities: ‘polygonal tundra complex’, ‘tussock tundra’, and ‘dwarsh shrub herb communities’. However, locally, high disturbance occurs by rapid thaw processes of ice-rich permafrost (first and third delta terraces) with habitats characterized by mid to advanced-stage plant succession: ‘moist to wet sedge communities’<em>, ‘</em>wet sedge communities’, ‘dry shrub communities’, and <em>‘</em>dry grass to wet sedge’ communities. Very high disturbance due to intense rapid thaw processes occurs at eroding cliffs and lake margins, in steep valleys and actively developing gullies resulting in barren surfaces with rims of sparsely vegetated transition zones. Given the link between plant communities and flooding as well as rapid thaw processes, we characterised the disturbance regimes for each habitat class (see legend in table) and provide an upscaling product in the form of a disturbance map for the entire Lena Delta.</p> <p> </p> <p>References: </p> <p>Stanford, J.
