Changes in species composition and richness in an alluvial hardwood forest over 52 yrs / Ilka Strubelt in Journal of Vegetation Science, vol. 28, n°2 (Année 2017)

While the total pool of species has not consistently increased, we found a strong increase in plot‐scale species richness of woody and herbaceous species. This overall increase and the slight decrease in the proportion of species typical of open habitats were probably driven by a decrease in light availability caused by less intensive management. Our results demonstrate that fine‐scale spatial environmental heterogeneity positively affects species richness. In contrast to recently reported findings, we found a decrease in the number of species with increasing nutrient content."

Large, ancient woodlands host high levels of biodiversity and can therefore deliver a number of ecosystem services. In contrast, smaller woodlands in agricultural landscapes, especially ancient woodlands, have a higher potential to deliver multiple ecosystem services on a per area basis. Despite their important contribution to agricultural landscape multifunctionality, small woodlands are not currently considered by public policies. There is thus an urgent need for targeted policy instruments to ensure their adequate management and future conservation in order to either achieve multiservice delivery at high levels or to maximize the delivery of specific ecosystem services."

Resurveying hedgerows in Northern Germany : Plant community shifts over the past 50 years / Kathrin Litza in Biological conservation, vol. 206 (Février 2017)

Public [article]  inBiological conservation > vol. 206 (Février 2017) . - pp. 226-235 Titre : Resurveying hedgerows in Northern Germany : Plant community shifts over the past 50 years Type de document : texte imprimé Auteurs : Kathrin Litza, Auteur ; Martin Diekmann, Auteur Année de publication : 2017 Article en page(s) : pp. 226-235 Langues : Anglais (eng) Catégories : [ZG] Allemagne Use for events before 1949 and after October 1990. [habitats/milieux] 84 - Alignements d'arbres, haies, petits bois, bocage, parcs Mots-clés : haie  acidification  valeur indicatrice d'Ellenberg  eutrophisation  suivi à long terme Résumé : "Resurveying is a powerful approach to investigate responses of plant species communities to a changing environment. We present a resurvey of hedgerows from the “Knick” landscape of eastern Schleswig-Holstein, Germany. The original survey was done by H. E. Weber in 1967 and new data from totally 51 semi-permanent plots was sampled in 2015. Hedgerows are a key near-natural habitat that can harbour a great biodiversity in otherwise agriculturally intensified landscapes. Our study reveals a distinct shift in the herbaceous species composition of the hedgerows over the past five decades. To understand the reasons for these changes, we compared the mean Ellenberg indicator values (EIVs) and measured pH values, as well as hedge shape parameters of the hedgerows between the recent and the original study. The main driver behind the change in species composition appeared to be the increase in nutrient supply. The hedge shape changed as well, indicating an altered hedgerow management. Interestingly, we found a contradictory relationship between measured pH values and mean EIVs for reaction: while the former showed a decrease over time, the latter suggested an increase. Species richness decreased in some groups (shrubs and herbaceous forest species) but increased in others (grass species and arable weed species), with an overall decline in species richness. An analysis of the species' changes in frequency in relation to their EIVs showed that species with higher nitrogen and temperature scores were more likely to have increased."
