Connectivity and succession of open structures as a key to sustaining light-demanding biodiversity in deciduous forests
<p>1. European forests are facing a rapid decline of light-demanding biota. This has prompted active interventions to re-establish and maintain partial habitat openness in protected areas. Managers of protected areas, however, need substantially more scientific evidence to support their decisions on where, when, and how to intervene.</p> <p>2. We investigated the importance of spatial continuity of open forest habitats in different years of succession, using six pairs of experimental clearings established in the formerly open, oak-dominated forests of the Podyji National Park (Czech Republic). In each pair, one clearing was connected to the forest edge, while the other was isolated in closed forest. We sampled butterflies (74 spp.), moths (435 spp.), saproxylic beetles (465 spp.), and vascular plants (567 spp.) on the 12 clearings during the first five years of succession. We then compared species richness, abundance, and composition of the four taxa between the two clearing types and along the succession.</p> <p>3. All studied insect groups were substantially more species-rich and more abundant in connected than in isolated clearings. Species composition of plants, moths, and butterflies differed between the clearing types.</p> <p>4. The number of species of all studied taxa generally increased from the first to the second or third year after cutting; species composition of all taxa differed among years. This suggests rapid changes in habitat quality and thus limited time for colonisation by light-demanding organisms.</p> <p>5. <i>Synthesis and applications</i>: Our results offer an evidence that spatial connectivity and rapid temporal dynamics are important habitat features for light-demanding insects. Attempts to create or restore habitats for light-demanding forest biota should take into account that: (i) Insects benefit from direct connection of new open patches to open habitats or flight corridors such as forest edges. (ii) Considering plants, the optimal solution is to connect newly created open forest habitats to existing habitats with established biota of high conservation value. (iii) Interventions should be carried out within short time intervals, i.e. within years rather than decades. (iv) A fine mosaic of interconnected<span>, open woodland patches in various successional stages is more beneficial than a single large patch with a single successional stage.</span></p>

Do dense layers of invasive plants elevate the foraging intensity of small mammals in temperate deciduous forests? A case study from Pennsylvania, USA
Monospecific stands of invasive plants can dramatically restructure habitat for fauna, thereby elevating population densities or promoting foraging of consumer species who benefit in the altered habitat. For example, dense stands of invasive plants may protect small mammals from predators, which in turn could increase foraging pressure on seeds that small mammals feed upon. We used a before-after, control-impact experimental design to test whether small mammal capture rates were higher and giving-up densities (GUDs) lower beneath dense stands of Berberis thunbergii, an invasive shrub with a rapidly expanding range throughout eastern North America. Our experimental design included three plot categories: 1) plots heavily invaded by B. thunbergii, 2) control plots lacking invasive shrub cover, and 3) invaded plots where we eradicated B. thunbergii midway through the study. Although our overall small mammal capture rate was low, small mammal captures were 65% higher in B. thunbergii invaded habitat relative to control plots and eradication lowered capture rates by 77%. GUDs were also 26% higher within B. thunbergii relative to control plots and eradication decreased GUDs by 65%. Our findings suggest that small mammals perceive dense stands of B. thunbergii as relatively safe foraging habitat. Prior surveys within our study locations revealed dramatically depressed tree seedling densities under B. thunbergii, thus invasive plants may promote intensive foraging by small mammals and reduce recruitment for species with foraged seeds or seedlings.
Mesophication in temperate Europe: a dendrochronological reconstruction of tree succession and fires in a mixed deciduous stand in Białowieża Forest / supporting data
<p>The attached data was gathered to investigate the successional changes in Bialowieza Forest mixed-deciduous stands by reconstructing the long-term tree population dynamics (tree-ring data). Traces of fires were documented from a 43ha area to explore whether fire was involved in shaping the succession of this habitat.</p>
Data from: Earthworm invasion, white-tailed deer and seedling establishment in deciduous forests of northeastern North America
1. Earthworm invasions and high deer populations are among many stressors threatening long-term population viability of forest understorey plants in northeastern North America. Stressor effects are typically tested one at a time, however, stressors often co-occur, and plants respond to effects of multiple stressors simultaneously. 2. We used a factorial design to test independent and combined effects of non-native earthworms and native white-tailed deer on survival of seedling transplants of 15 native understorey plants in 5 forests in New York State. 3. Earthworm biomass was negatively correlated with survival of 12 of 15 species. We found no interactive effect of deer and earthworms, but did find a positive, non-consumptive effect of deer on Geranium maculatum and P. virginianum survival. 4. Deer and earthworm presence/absence indirectly influenced other trophic levels: earthworm presence increased the likelihood of insect attack, and deer exclusion increased the likelihood of rodent attack disturbance of transplants. 5. Synthesis: Invasive earthworms negatively affected seedling survival of many understorey plants, including species previously thought to benefit from earthworm associations. This effect was a function of earthworm biomass, a surrogate for earthworm activity. We expect deer herbivory to increase in importance, including indirect effects, as seedlings grow into browse height over the next years. Investigations of co-occurring stressors can result in 'ecological surprises' including previously overlooked non-consumptive effects or effects on other trophic levels.
Data from: Fire and non-native grass invasion interact to suppress tree regeneration in temperate deciduous forests
1. While many ecosystems depend on fire to maintain biodiversity, non-native plant invasions can enhance fire intensity, suppressing native species and generating a fire–invasion feedback. These dynamics have been observed in arid and semi-arid ecosystems, but fire–invasion interactions in temperate deciduous forests, where prescribed fires are often used as management tools to enhance native diversity, have rarely been investigated. 2. Here we evaluated the effects of a widespread invasive grass on fire behaviour in eastern deciduous forests in the USA and the potential effects of fire and invasions on tree regeneration. We planted native trees into invaded and uninvaded forests, quantified fuel loads, then applied landscape-scale prescribed fires and no-burn controls, and measured fire behaviour and tree seedling and invasive plant performance. 3. Our results show that fires in invaded habitats were significantly more intense, including higher fire temperatures, longer duration and higher flame heights, even though invasions did not alter total fuel loads. The invasion plus fire treatment suppressed native tree seedling survival by 54% compared to invasions without fire, and invasions reduced natural tree recruitment by 66%. 4. We also show that invasive plant biomass did not change from one season to the next in plots where fire was applied, but invader biomass declined significantly in unburned reference plots, suggesting a positive invasive grass–fire feedback. 5. Synthesis and applications. These findings demonstrate that fire–invasion interactions can have significant consequences for invaded temperate forest ecosystems by increasing fire intensity and reducing tree establishment while promoting invasive plant persistence. To encourage tree regeneration and slow invasive spread, we recommend that forest managers remove invasions prior to applying prescribed fires or avoid the use of fire in habitats invaded by non-native grasses.
