“…The decreased lowland plant growth, and for bilberry also a distinct negative-temporal warming effect and increased shoot mortality, in response to growing-season warming in our study may add to the list of responses and factors that may shape the common phenomenon of "trailing edge" populations (Parmesan, 2006). Such demographic trends may eventually result in reduced abundance of dwarf shrubs in temperate vs. boreal areas (Hedwall and Brunet, 2016), and perhaps even in boreal vs. alpine areas in future (Puchałka et al, 2023).…”

Climate change impacts on species and ecosystem functioning may depend on climatic context and study systems. Climate warming and intensified herbivory are two stressors to plants that often appear in combination and are predicted to increase in cold environments. Effects of multiple drivers on plant performance are difficult to predict and warrant studies that use experimental manipulations along climatic gradients to produce more realistic knowledge. Our three study sites by the Sognefjord in Norway, that differed mainly in climatic conditions (ca. 5°C growing season difference), ranged from hemi-boreal lowland (100 masl, Low), via boreal mid-montane (500 masl) to alpine timberline (900 masl, High) bioclimates. At each site, in a randomized block design, we simulated growing-season warming using open-top chambers (OTCs) and experimentally induced herbivory resistance using the plant hormone methyl jasmonate (MeJA). We recorded growth, mortality, flower and fruit numbers, and insect herbivory on tagged ramets in permanent plots across three years (2016-2018) in three open woodland populations of two functionally important plant species with contrasting traits, Vaccinium myrtillus (bilberry) and V. vitis-idaea (lingonberry). Growth of both dwarf shrubs decreased with warming in the warm lowland populations (Low) but increased in the alpine populations (High). Shoot mortality increased most with warming at Low but was reduced at High. Reproduction, both flowering and fruiting, decreased with induced resistance treatment, but the effect was larger when warmed for bilberry and increased with elevation for both species. Leaf herbivory in bilberry increased with warming at Low but decreased at High. The combined warming and resistance treatment had only synergistic negative interaction effects on fruit numbers in bilberry. The clear context- and species-dependent effects of climate warming and increased resistance in this study may predict a potential decline in performance, as well as abundance and distribution, of these functionally important Vaccinium species at our lowest site. Bilberry reproduction appeared to be particularly susceptible to both climate warming and induced resistance in the manipulated populations. Such combined negative effects on plant performance are likely to have considerable knock-on effects via altered species’ interactions and ecosystem functioning.

“…Modelling studies have also suggested climate-change dependent niche contractions of ca. 40-50% in Europe by 2080, which will mostly occur in the warm part of their range (Puchałka et al, 2023). Bilberry and lingonberry are both mass-flowering species and produce abundant berries, but they diverge in growth and defence strategies.…”

“…Other mapping of mountain shrublands has been proposed using so-called big data approaches with shrublands defined as woody vegetation with height under 5 m (Inglada et al 2017, Zanaga et al 2021. In contrast, distribution maps at shrub species level have been obtained using species distribution modeling (Komac et al 2016, Puchalka et al 2023). Overall, these approaches are complementary, as in general, definition of 'shrublands' is too broad to allow biogeographical characterization in big data approach, while shrub species mapping are generally based on coarse climatic data sets that result in limited spatial accuracy.…”

Highlights• Ericaceous-dominated mountain shrubland are key habitats in alpine ecosystems, and understanding their dynamics is limited by the difficulties of mapping them using remote sensing.• Pigment-sensitive spectral indices based on Sentinel-2 bands used within a specific phenological window successfully allows Ericaceous-dominated mountain shrublands mapping.• Topoclimatic factors related to water conditions are driving the distribution of Ericaceous-dominated mountain shrublands at regional scale while temperatures drives the upper elevation boundaries.• Decline of the traditional agro-sylvo-pastoral system is suggested as a common critical juncture in the trajectory of shrublands across all mountain ranges.• Local topoclimatic conditions is suggested to have led to contrasting growth and encroachment depending on the location within the ecological niche of the habitat identified in this analysis.

“…In the case of commercially important woody species intentionally planted outside their native range, the successful development of juvenile specimens from seeds, naturally dispersed or collected and sown directly to the ground, also has a fundamental meaning for forest management due to the interest in less costly regeneration of stands (Löf et al., 2019 , 2021 ; Pötzelsberger et al., 2020 ). Ongoing climate changes (IPCC, 2022 ) and predicted range shifts of native species (Koch et al., 2022 ; Puchałka, Paź‐Dyderska, Woziwoda, & Dyderski, 2023 ) additionally force the development of more effective practices for forest regeneration, also with use of introduced tree species (Badano & Sánchez‐Montes de Oca, 2022 ; Brang et al., 2014 ; Dyderski et al., 2018 ; Puchałka, Paź‐Dyderska, Jagodziński, et al., 2023 ). The abundant uncontrolled encroachment of juvenile specimens into forest patches located outside areas of alien tree cultivation, however, can be undesirable if introduced species negatively impact native ecosystems (Brundu & Richardson, 2016 ; Dyderski & Jagodziński, 2021 ; Richardson et al., 2000 ).…”

A previous study on the encroachment of North American northern red oak Quercus rubra L. into the mesic Scots pine forest (in central Poland) revealed high abundances of seedlings and saplings under shrubs, with lower abundances in open areas or clumps of bilberry Vaccinium myrtillus L. It was unclear whether the regeneration success of Q. rubra is enhanced by the presence of shrubs due to their “nurse effect”, and how burying acorns of different sizes in soil or moss affects the survival of oak seeds and seedlings (a “burial effect”). Results of a previous observational study were verified in an experimental study: a pool of 900 large‐, medium‐, and small‐sized acorns was sown under moss cover in open areas and within bilberry clumps and in soil under shrubs in 2018 and monitored for 3 years in natural conditions. The majority of sown acorns were lost, mainly due to acorn pilferage, lack of germination and the death of sprouting acorns. However, acorn and seedling survival depended significantly on acorn size and differed among the microsites studied. Viable seedlings were twice as likely to develop from large‐ and medium‐sized as from small‐sized acorns, and they grew mainly from acorns sown under moss cover, confirming a positive “burial effect.” Seedling survival was three times higher in bilberry and open areas, than under shrubs; however, seedlings “nursed” by shrubs were less threatened by large ungulates. Only a small part of the pool of sown acorns contributes to the reproductive success of Q. rubra in the mesic Scots pine forest. Microsites characteristic to this type of forest are suitable for northern red oak regeneration; however, bilberry favors acorn survival and germination and early seedling growth, moss cover favors acorn survival and germination, while shrubs protect surviving seedlings from herbivory.
