Ecological Succession palaeoenvironmental change and depositional sequences of barremian aptian shallow water carbonates in northern oman
Sedimentology, 2002Co-Authors: Bernard Pittet, Frans S. P. Van Buchem, Heiko Hillgärtner, Philippe Razin, Jürgen Grötsch, Henk DrosteAbstract:Barremian and Aptian shallow-water carbonate facies (uppermost Lekhwair, Kharaib and Shuaiba Formations) are described from outcrops in northern Oman. Based on facies analysis and bedding pattern, three orders of depositional sequences are defined (third to fifth order) and correlated between sections. Over the course of three third-order sequences, covering the Barremian to Lower Aptian, a third-order depositional pattern is documented that consists of a Succession of three distinct faunal assemblages: discoidal orbitolinids and calcareous algae were deposited during early transgression; microbialites and microencrusters dominate the late transgressive to early highstand facies; and a rudist- and miliolid-dominated facies is typical of the highstand. This Ecological Succession was controlled largely by palaeoenvironmental changes, such as trophic level and clay influx, rather than sedimentological factors controlled by variations in accommodation space. Orbitolinid beds and carbonates formed by microbialites and microencrusters seem to be the shallow-water carbonate response to global changes affecting Late Barremian to Aptian palaeoclimate and palaeoceanography.

mowing influences community level variation in resource use strategies and flowering phenology along an Ecological Succession on mediterranean road slopes
Applied Vegetation Science, 2017Co-Authors: Diane C. Bouchet, Pierre-olivier Cheptou, François MunozAbstract:Questions How do species composition, resource-use strategy and flowering phenology change and relate to each other in road slope plant communities along an Ecological Succession after construction work? How does recurrent mowing influence resource-use Successional trajectory and flowering phenology in communities? Does intraspecific variation contribute to these community-level functional responses? Location Road slopes in Mediterranean southern France. Methods We designed a chronosequence of 25 road slopes, each including both unmown and yearly mown parts. We analysed the influence of age and mowing on community-level trait values (CWM) of Leaf Dry Matter Content (LDMC), Specific Leaf Area (SLA), Onset of Flowering Date (OFD), End of Flowering Date (EFD) and Flowering Duration (FDur). We tested for contribution of intraspecific variation of traits to these functional variations. We also tested for relationship between changes in taxonomic composition, environmental parameters and functional responses. Results We found a slower Successional variation of resource-use strategies in communities undergoing recurrent mowing, compared to unmown vegetation. Onset of flowering was earlier in mown communities. End of flowering and flowering duration did not directly depend on Successional stage or mowing but related to resource-use strategies. Species turnover was an important driver of functional variation and the major components of plant taxonomic variation were primarily related to environmental and functional changes. Conclusions On road slopes, Successional changes in functional and taxonomic composition were influenced by mowing, which did not totally prevent vegetation changes. Disturbance by mowing impacted resource-use strategy and indirectly influenced flowering phenology by limiting plant investment into resource conservation in aerial parts. Community-level relationship between resource-use strategy and flowering phenology suggests a consistent trade-off between vegetative growth and flowering phenology among plant species within communities. Our findings help to understand how recurrent disturbances can influence Successional trajectories in Mediterranean ecosystems. This article is protected by copyright. All rights reserved.
