Long-term vegetation changes in Nardus grasslands indicate eutrophication, recovery from acidification, and management change as the main drivers
<p>Abstract</p> <p>Questions</p> <p>Which trends and patterns of community change occurred in <em>Nardus</em> grasslands over recent decades in parts of the Continental biogeographic region of Germany? Are patterns and trends consistent across two study regions? Do impacts of environmental changes on <em>Nardus</em> grasslands in Central Europe correspond to those identified in the European Atlantic biogeographic region?</p> <p>Location</p> <p>East Hesse Highlands, Germany</p> <p>Methods</p> <p>In 2012-2015, we re-surveyed quasi-permanent plots that had been initially surveyed between 1971 and 1987, and re-measured soil parameters. We tested for differences in species frequency and cover, mean Ellenberg indicator values, species richness, and soil variables. Nitrogen- and sulphur-deposition data were analysed to evaluate possible effects of atmospheric pollutants. We used regression- and redundancy analyses to identify environmental drivers responsible for changes in species composition.</p> <p>Results</p> <p>Across regions, we found significant increases in soil pH, Ellenberg R and N indicator values, plant-nutrient indicators, forbs, species of agricultural grasslands and of fallows. By contrast, the C:N ratio<em>, Nardus</em> grassland specialists, low-nutrient indicators, and graminoids declined. Changes in species composition were related to changes in pH and management. There was a strong decrease in sulphur and a moderate increase in nitrogen deposition, whose local scale pattern did not correlate with changes in soil parameters. However, there was an effect of local NH<sub>y</sub> changes on species composition.</p> <p>Conclusion</p> <p>The findings indicate significant overall eutrophication, a trend towards less acidic conditions and insufficient management, which are widely consistent across our study regions and correspond to recent reports of vegetation changes and recovery from acidification in the Atlantic biogeographic region. We assume the reduced sulphur deposition during recent decades to be a major driver of these changes, combined with increased nitrogen deposition and reduced management intensity. This suggests a large-scale validity of processes that influenced changes in <em>Nardus</em> grasslands of Western and Central Europe.</p>
Data repository from Boudewijn van Lieshout' thesis A comparison between Normalized Difference Vegetation Indices calculated from Sentinel 2A satellite data and high-resolution UAV imagery in Tanzania
<p>Monitoring vegetation is imperative for policy design and efficiency measurements. Frequent data collection, easy and inexpensive accessibility of images and the possibility of large area analysis, makes it still valuable to use satellite imagery. This study aims to examine how a Normalized Difference Vegetation Index (NDVI) measured with Sentinel-2A satellite data relates to an NDVI from Unmanned Aerial Vehicles (UAV henceforth) in study areas Chamwino Mlimwa and Chemba Waida, Tanzania.</p>
Vegetative characters of Agave landraces used for the production of pulque in Tlaxcala.
<p>Raw data of 19 morphological variables of vegetative characters of nine Agave landraces (N=478 individuals) used for the production of pulque in 10 localities of Tlaxcala. These data were used to analyze and describe the morphological diversity of these varieties.</p> <p>Nine <em>Agave</em> landraces used for pulque production in 10 localities Tlaxcala were analyzed: <em>Agave salmiana</em> subsp. <em>salmiana</em> ‘Amarillo’, ‘Ayoteco’, ‘Colorado’, ‘Chalqueño’, ‘Chino’, ‘Manso’, ‘Prieto’, and ‘Xilomelt’ and <em>Agave mapisaga</em> var. <em>mapisaga</em> ‘Palmilla’. Twenty-two populations of 13–35 individuals were included in the study (N = 478 individuals). Both landraces and wild individuals were identified at the species and subspecies level following García-Mendoza’s (2011) and Gentry’s (1982) taxonomic keys. Twenty morphological variables were measured in de field between 2018 and 2019.</p> <p> </p>
Fixed or mixed? variation in tree functional types and vegetation structure in a forest-savanna ecotone in West Africa
<p></p><p>We analysed thirty-five 400-m<sup>2</sup> plots encompassing forest, savanna and intermediate vegetation types in an ecotonal area in Ghana, West Africa. Across all plots, fire frequency was over a period of 15 years relatively uniform (once in 2–4 years). Although woodlands were dominated by species typically associated with savanna-type formations, and with forest formations dominated by species usually associated with closed canopies, these associations were non-obligatory and with a discrete non-specialized species grouping also identified. Across all plots, crown area index, stem basal area and above-ground biomass were positively associated with higher soil exchangeable potassium and silt contents: this supporting recent suggestions of interplays between potassium and soil water storage potential as a significant influence on tropical vegetation structure. We also found an average NDVI cover increase of ~0.15% year<sup>−1</sup> (1984–2011) with plots dominated by non-specialized species increasing more than those dominated by either forest- or savanna-affiliated species. Our results challenge the traditional view of a simple forest vs. savanna dichotomy controlled by fire, and with our newly identified third non-specialized species grouping also potentially important in understanding ecotonal responses to climate change.</p><p></p>

Species interactions across trophic levels mediate rainfall effects on dryland vegetation dynamics
<p>Arid ecosystems are strongly limited by water availability, and precipitation plays a major role in the dynamics of all species in arid regions, as well as the ecosystem processes that occur there. However, understanding how biotic interactions mediate long-term responses of dryland ecosystems to rainfall remains very fragmented. We report on a unique large-scale field experiment spanning 25 years and three trophic levels (plants, small mammal herbivores, predators) in a dryland ecosystem in the northern Chilean Mediterranean Region where we assessed how biotic interactions influence the long-term plant community responses to precipitation. As the most persistent ecological changes in dryland systems may result from changes in the structure, cover, and composition of the perennial vegetation, we emphasized the interplay between bottom-up and top-down controls of perennial plants in our analyses. Rainfall was the primary factor affecting the dynamics of, and interactions among, plants and small mammals. Ephemeral plant cover dynamics closely tracked short-term annual rainfall, but seemed unaffected by top-down controls (herbivory). In contrast, the response of the perennial plant cover to precipitation was mediated by: (i) a complex interplay between subtle top-down (herbivory) controls that become more apparent in the long-term, (ii) competition with ephemeral plants during wet years, and (iii) an indirect effect of predators on subdominant shrubs and perennial herbs. This long-term field experiment highlights how climate-induced responses of arid perennial vegetation are influenced by interactions across trophic levels and temporal scales. In the face of global change, understanding how multi-trophic controls mediate dryland vegetation responses to climate is essential to properly managing the conservation of biodiversity in arid systems.</p>
A dicamba resistance endowing IAA16 mutation leads to significant vegetative growth defects and impaired competitiveness in kochia (Bassia scoparia)
<p class="CxSpFirst"><span>Precise quantification of the fitness cost of synthetic auxins resistance has been impeded by lack of knowledge for the genetic basis of resistance in weeds. Recent elucidation of a resistance endowing IAA16 mutation (G73N) in a key weed species kochia (<i>Bassia scoparia</i>), allows detailed characterization of the contribution of resistance alleles to weed fitness, both in the presence and absence of herbicides.<b> </b>Different G73N genotypes from a segregating resistant parental line (9425) were characterized for cross resistance to dicamba, 2,4-D and fluroxypyr, and changes on stem/leaf morphology and plant architecture. Plant competitiveness and dominance of the fitness effects was quantified through measuring biomass and seed production of three F<sub>2</sub> lines in two runs of glasshouse replacement series studies. G73N confers robust resistance to dicamba but only moderate to weak resistance to 2,4-D and fluroxypyr. G73N mutant plants displayed significant vegetative growth defects: 1) being 30-50% shorter with a more tumbling style plant architecture; 2) had thicker and more ovate (versus lanceolate and linear) leaf blades with lower photosynthesis efficiency, and 40-60% smaller stems with less developed vascular bundle systems. F<sub>2 </sub>mutant plants had impaired plant competitiveness, which produced up to 90% less biomass and seeds in the replacement series study. The pleiotropic effects of G73N was mostly semi-dominant (0.5) and fluctuated with the environments and traits measured. G73N is associated with significant vegetative growth defects and reduced competitiveness in synthetic auxin resistant kochia. Management practices should target resistant kochia's high vulnerability to competition to effectively contain the spread of resistance.</span></p>
Large herbivores maintain a two-phase herbaceous vegetation mosaic in a semi-arid savanna
<ol> <li>Many arid and semi-arid rangelands exhibit distinct spatial patterning of vegetated and bare-soil-dominated patches. The latter potentially represent a grazing-induced, degraded ecosystem state, but could also arise via mechanisms related to feedbacks between vegetation cover and soil moisture availability that are unrelated to grazing. The degree to which grazing contributes to the formation or maintenance of degraded patches has been widely discussed and modelled, but empirical studies of the role of grazing in their formation, persistence, and reversibility are limited. </li> <li>We report on a long-term (17 yr) grazing removal experiment in a semi-arid savanna where vegetated patches composed of perennial grasses were interspersed within large (>10 m<sup>2</sup>) patches of bare soil. </li> <li>Short term (3 yr) grazing removal did not allow bare patches to become revegetated, whereas following long-term (17 yr) grazing removal, bare soil patches were revegetated by a combination of stoloniferous grasses and tufted bunchgrasses. In the presence of grazers, stoloniferous grasses partially recolonized bare patches, but this did not lead to full recovery or to the establishment of tufted bunchgrasses. </li> <li>These results show that grazers alter both the balance between bare and vegetated patches, as well as the types of grasses dominating both patch types in this semiarid savanna. </li> <li>Synthesis: Large herbivores fundamentally shaped the composition and spatial pattern of the herbaceous layer by maintaining a two-phase herbaceous mosaic. However, bare patches within this mosaic can recover given herbivore removal over sufficiently long time scales, and hence do not represent a permanently degraded ecosystem state. </li> </ol>
