Genetic data from: Cryptic persistence and loss of local endemism in Lake Constance charr subject to anthropogenic disturbance
<p>Habitat restoration can help to protect and support endangered species. Following the restoration of Lake Constance to oligotrophic conditions, deep-water charr (originally described as <em>Salvelinus</em> <em>profundus</em> Schillinger, 1901) were rediscovered after more than 40 years of presumed extinction caused by eutrophication. Subsequent targeted surveys lead to the capture of a further 127 deep-water charr and 233 sympatric normal charr, <em>Salvelinus</em> cf. <em>umbla</em>. Given a history of intensive stocking in the lake and the possibility of introgressive hybridization, a discussion arose about the genetic status and future conservation strategies of both forms. The current study gathered life history traits and morphological and population genomic data for both extant forms, for comparison with 60–120 years' worth of historical data and museum specimens. The extant deep-water charr resembled historical specimens in terms of body shape, but significant differences between historical and extant normal charr included a decline in gill raker number over time and distinctly different body shapes and growth patterns. RAD-based population genomic analyses of the contemporary samples support these results, revealing the two extant forms to be highly divergent, albeit with a few putative hybrids. SNPs-based population assignment tests of historical and contemporary samples strongly suggest that deep-water charr persisted unaltered in Lake Constance during the eutrophic phase. Meanwhile, none of the historical genomic samples could be assigned to the extant normal <em>S</em>. cf. <em>umbla</em> population. Functional analyses of gill raker number and stocking intensity pointed to stocking with non-endemic charr as the most likely reason for the disappearance of the endemic normal form. These results show that interplay between different anthropogenic impacts, i.e. eutrophication and stocking can lead to irreversible but hard-to-detect impacts on endemic biodiversity. Understanding these impacts is a prerequisite for effective conservation of endangered populations of cryptic fish.</p>
Local canopy disturbance as an explanation for long-term increases in liana abundance
<p>Canopy disturbance explains liana abundance and distribution within tropical forests and thus may also explain the widespread pattern of increasing liana abundance; however, this hypothesis remains untested. We used a 10-year study (2007 – 2017) of 117,100 rooted lianas in an old-growth Panamanian forest to test whether local canopy disturbance explains increasing liana abundance. We found that liana density increased 29.2% and basal area 12.5%. The vast majority of these increases were associated with clonal stem proliferation following canopy disturbance, particularly in liana-dense, low-canopy gaps, which had far greater liana increases than did undisturbed forest. Lianas may be ecological niche constructors; arresting tree regeneration in gaps and thus creating a high-light environment that favors sustained liana proliferation. Our findings demonstrate that liana abundance is increasing rapidly and their ability to proliferate via copious clonal stem production in canopy gaps explains much of their increase in this and possibly other tropical forests.</p>
Data for: Local conditions matter: Minimal and variable effects of soil disturbance on microbial communities and functions in European vineyards
<p>Soil tillage or herbicide applications are commonly us<span>ed in agriculture for weed control. These measures may also represent a disturbance for soil microbial communities and their functions. However, the generality of response patterns of microbial communities and functions to disturbance have rarely been studied at large geographical scales. We investigated how a soil disturbance gradient (low, intermediate, high), realized by either tillage or herbicide application, affects diversity and composition of soil bacterial and fungal communities as well as soil functions in vineyards across five European countries. Microbial alpha-diversity metrics responded to soil disturbance sporadically, but inconsistently across countries. Increasing soil disturbance changed soil microbial community composition at the European level. However, the effects of soil disturbance on the variation of microbial communities were smaller compared to the effects of location and soil covariates. Microbial respiration was consistently impaired by soil disturbance, while effects on decomposition of organic substrates were inconsistent and showed positive and negative responses depending on the respective country. </span><span>Therefore, we conclude that it is difficult to extrapolate results from one locality to others because microbial communities and environmental conditions vary strongly over larger geographical scales.</span><span> </span></p>
