Insect herbivore impact on a keystone plant colonist in primary succession at Mount St. Helens from 1994 to 2017
This data base contains estimates of damage to lupin (Lupinus lepidus var. lobbii) by several species of leaf-tying and root-boring moth larvae (Lepidoptera), along with associated estimates of vegetation cover, in primary successional sites at Mount St. Helens. The surveys began in 1993 and are ongoing; This database includes data for 1994, 1995, and 1998-2017. Surveys were located at a variety of primary successional sites on Mount St. Helens’ Pumice Plain. Surveys generally occurred in mid to late August, when leaf-miner damage is at its maximum, but prior to maximum damage by root-borers. The number of sites, location of sites, and types of data collected varied across years and, but lupin cover, bare ground, and % lupin damage are reliable across the time series. Please note, leaf-miner damage has been been temporarily deleted from lupin.csv. Contact data authors if you seek a collaboration using the deleted data.

Data from: The last 50 years of climate-induced melting of the Maliy Aktru glacier (Altai Mountains, Russia) revealed in a primary ecological succession
In this article, we report and discuss the results obtained from a survey of plants, microorganisms (bacteria and fungi), and soil elements along a chronosequence in the first 600 m of the Maliy Aktru glacier's forefront (Altai Mountains, Russia). Many glaciers of the world show effects of climate change. Nonetheless, except for some local reports, the ecological effects of deglaciation have been poorly studied and have not been quantitatively assessed in the Altai Mountains. Here, we studied the ecological changes of plants, fungi, bacteria, and soil elements that take the form of a primary ecological succession and that took place over the deglaciated soil of the Maliy Aktru glacier during the last 50 year. According to our measurements, the glacier lost about 12 m per year during the last 50 years. Plant succession shows clear signs of changes along the incremental distance from the glacier forefront. The analysis of the plant α‐ and β‐diversity confirmed an expected increase of them with increasing distance from the glacier forefront. Moreover, the analysis of β‐diversity confirmed the hypothesis of the presence of three main stages of the plant succession: (a) initial (pioneer species) from 30 to 100 m; (b) intermediate (r‐selected species) from 110 to 120–150 m; and (c) final (K‐selected species) from 150 to 550. Our study also shows that saprotrophic communities of fungi are widely distributed in the glacier retreating area with higher relative abundances of saprotroph ascomycetes at early successional stages. The evolution of a primary succession is also evident for bacteria, soil elements, and CO2 emission and respiration. The development of biological communities and the variation in geochemical parameters represent an irrefutable proof that climate change is altering soils that have been long covered by ice.
Data from: Plant-fungal symbiosis affects litter decomposition during primary succession
Microbial symbionts of plants can affect decomposition by altering the quality or quantity of host plant tissue (substrate) or the micro-environment where decomposition occurs (conditioning). In C3 grasses, foliar fungal endophytes (Clavicipitaceae) can increase plant resistance to drought and/or produce alkaloids that reduce herbivory – effects that may also influence host litter composition and subsequent litter decomposition. We studied the effect of the endophyte Epichloë sp. on litter decomposition in the Great Lakes dunes (USA) using a reciprocal design altering endophyte presence/absence in both American beachgrass Ammophila breviligulata substrate (litter bags) and its conditioning of the decomposition microenvironment. Symbiont treatments were crossed with rain-out shelters that altered growing season precipitation. The first year of decomposition, senesced leaf substrate from A. breviligulata with Epichloë decomposed 21% faster than endophyte-free substrate. By the third year, conditioning by live symbiotic plants reduced cumulative decomposition by 33% compared to plots planted with endophyte-free plants. Of the traits we examined – litter quantity, C:N ratio, mineral composition, fungal colonization, and carbon chemistry – increased litter quantity via greater tiller production was the primary trait shift associated with endophyte symbiosis. Epichloë in A. breviligulata litter also altered litter nitrogen decomposition dynamics, as evidenced by lower nitrogen and protein content in decomposed tissue from plants that hosted the endophyte. Differences in initial litter quality and subsequent colonization by saprotrophic fungi were ruled out as key drivers. Altered precipitation had negligible effects on decomposing processes in the dunes. Grass–Epichloë symbiosis altered nutrient cycling through increasing the rate of litter decomposition when present in the litter and through reducing litter decomposition by conditioning the decomposition microenvironment. Epichloë are widespread symbionts of grasses. Thus, their effects on decomposition could be an important, but often overlooked, driver of nutrient cycling in grass-dominated ecosystems.
The role of howler monkeys (Alouatta caraya) in the primary succession of the Paraná flooded forest (Argentina)
<p>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 <i>Alouatta caraya</i> in the primary succession dynamics of the Paraná flooded forest, in northeastern Argentina. This was achieved by studying the recruitment of saplings in the latrines of <i>A. caraya</i> groups inhabiting the forest in the first stages of succession and the distribution of plant species in relation to the age of the forest. The results showed that: (a) young forest areas were dominated by tree species dispersed by water, wind, birds, bats and fishes, whereas older forest areas were dominated by species dispersed by <i>A. caraya</i>,<i> </i>with individuals of some species present in young forests; (b) the floristic composition of saplings growing in <i>A. caraya</i> latrines of young forest areas was similar to that of old forest areas; and (c) saplings growing in young forest areas were heavily associated with <i>A. caraya</i> latrines and corresponded to species from older forest areas. The results allow the conclusion that <i>A. caraya</i> plays a role in the last phase of primary succession of the Paraná flooded forest, as well as in contributing to an increase in the structural complexity and species diversity in the young areas of the Paraná islands.</p>
