Abstract:
... We analyzed plants and their traits in dolines, which are characteristic enclosed terrain depressions on carbonate (karst) plateaus. These landforms range from a few meters to over 100 m in diameter, their depth generally varying from a few meters to a few tens of meters. A pronounced ecological gradient can be found from the bottom to the top, starting from humid, cool and shaded bottoms to sunny ...

Abstract:
... The Fluvial Biogeomorphic Succession phase model (FBS model) differentiates Geomorphic (G), Pioneer (P), Biogeomorphic (B) and Ecological (E) phases of hydro-geophysical-biological interactions in river systems. To date, quantitative applications of this model have been restricted to field surveys of vegetation composition analysis at the patch-scale. Here we develop a biogeomorphic landform mappi ...

Abstract:
... Scientific interest in debris-covered glaciers (DCGs) significantly increased during the last two decades, primarily from an abiotic perspective, but also regarding their distinctive ecology. An increasing body of evidence shows that, given a minimum of debris thickness and sufficient substrate stability, DCGs host surprisingly diverse plant assemblages, both floristically and structurally, despit ...

Abstract:
... The onset of agriculture improved the capacity of ecosystems to produce food, but inadvertently altered other vital ecosystem functions. Plant traits play a central role in determining ecosystem properties, therefore we investigated how the onset of agriculture in Europe changed plant trait composition using 78 pollen records. Using a novel Bayesian approach for reconstructing plant trait composit ...

Abstract:
... Studying the patterns of dominance and species composition of legumes can contribute to more precise models for nutrient cycling, especially the N-cycle. Leguminosae is the most important family in Central Amazonian floodplain forests surrounding large rivers. The floodplains are classified as nutrient-poor (igapó) and nutrient-rich (várzea) ecosystems. In this study, we contrast patterns of domin ...

Abstract:
... Thanks to the recently published papers on the classification and diagnostics of soils in Russia, significant progress has been made in theoretical and practical soil science. Here, we outline the principles of the classification of peat soils, which occupy approximately 9% of the soil resources in Russia and annually increasing. As is shown, the organic and mineral parts of peat soils form a gene ...

Abstract:
... In disturbed forests, Atelidae primates, such as howler monkeys, are known to play a key role in the dynamics of secondary succession. However, little is known about their role in primary succession. Thus, the aim of the present study was to evaluate the role of the howler monkey Alouatta caraya in the primary succession dynamics of the Paraná flooded forest, in northeastern Argentina. This was ac ...

Abstract:
... Predation can effectively limit insect herbivores with cascading effects on plant community composition and diversity of tropical rainforests. Assessing variation in predation is therefore important to understand the mechanisms structuring complex rainforest ecosystems. Variation in predation with time of day may provide herbivores with temporal enemy‐free space. Trichomes (plant hairs) may provid ...

Abstract:
... Switching plant species visited by pollinators (partner flexibility) has been proposed as a behavioural mechanism able to attenuate the negative impacts of shifts in plant communities on pollination. However, it is unclear whether the magnitude of such response is generalizable or depends on the environmental context. Moreover, the ability of pollinators to exploit plants with dissimilar traits (t ...

Abstract:
... Beta(β)‐diversity, or site‐to‐site variation in species composition, generally decreases with increasing latitude, and the underlying processes driving this pattern have been challenging to elucidate because the signals of community assembly processes are scale‐dependent. In this meta‐analysis, by synthesising the results of 103 studies that were distributed globally and conducted at various spati ...

Abstract:
... AIMS: Dynamics of plant communities are an outcome of species’ responses to the external environment influenced by species’ life history, growth patterns and their mutual interactions. We aimed to disentangle the long‐term directional trends, likely associated with decadal change in environmental conditions, from short‐term species fluctuations. LOCATION: Krkonoše Mountains, North Bohemia, Czech R ...

Abstract:
... Ecological restoration interventions, in most cases, aim to restore habitat structure and plant community composition, thus re‐establishing ecosystem functioning as similar as possible to that of the pre‐existing natural ecosystem. However, given the difficulty of cultivating many species, that goal seems unattainable, unless “if you build it, they will come.” Here we addressed the Field of Dreams ...

Abstract:
... The North American Waterfowl Management Plan highlights the importance of enhancing waterfowl habitat for productivity and resilience. Many forms of land management are conducted in wetlands to support the diverse communities of waterfowl and other species. Primary burrowing crayfish are also abundant and important in these environments, but little research is available assessing the effects of wa ...

Abstract:
... Pollen morphology is species-specific and its identification can inform many different research objectives, including those focused on understanding pollinator niche breadth, pollen transfer dynamics, and factors driving plant community composition. Community-wide characterization of pollen can thus accelerate research on plant-pollinator interactions on both contemporary and historical time frame ...

Abstract:
... Fire is one of the main factors shaping vegetation characteristics around the world, with deep and complex effects on higher levels of the food web and ecosystem functioning. Specialist insects tend to be more vulnerable to fire than generalists due to their higher dependency on host plants; however, fire effects on specialist insects are still not clearly known. Our aim was to understand how fire ...

Abstract:
... Plant species growing on gypsum substrates, usually found in arid and semi-arid zones, create characteristic landscapes that can harbor highly specialized species, several of which are endemic. In the Cuatro Ciénegas basin (CCB) gypsum is abundant and creates patches of plant assemblages, but little is known about the floristic differences between them and the ecological factors driving them. In t ...

Abstract:
... Sand prairies experience relatively high rates of small-scale disturbance, feature a high complement of annual plant species, and are fairly dynamic in terms of year-to-year micro-scale species composition. In summer 2011, an underground natural gas pipeline was installed across Sand Prairie Natural History Reservation 19 km west of North Newton, KS. The resulting excavation left a strip 560 m lon ...

This study was conducted in Menfeskidus Monastery Forest in Berehet district North Shoa Zone of Amhara Regional State, Central Ethiopia, to investigate the floristic composition, species diversity, vegetation structure, and regeneration status of the forest.

Abstract:
... In grasslands, the interactions of foliar fungal diseases and their host plants are largely dependent on grazing by large herbivores. However, the relative importance of direct (i.e. pathogen removal) and indirect effects (i.e. via changes in plant community composition) of long‐term grazing on foliar fungal diseases remains largely unexplored, especially under varied grazing intensities. We condu ...

Abstract:
... Floristic composition within a geographic area is driven by a wide array of factors from local biotic interactions to biogeographical processes. Subtropical East Asia is a key biodiversity hotspot of the world, and harbors the most families of extant gymnosperms and a large number of endemic genera with ancient origins, but rare phylogenetic studies explored whether it served as a diversification ...
