1Shoot-level biomass allocation is affected by shoot type in Fagus sylvatica显示文摘Aims The present study aims(i)to examine if recently reported interspecific shoot-level biomass allocational trade-offs,i.e.isometric trade-offs between leaf mass(LM)and stem mass(SM)and between leaf size and leaf number,hold intraspecifically and(ii)to explore whether those scaling relationships are independent of shoot type(i.e.long vs.short shoots).Methods In order to address our questions,we used Fagus sylvatica saplings growing under a broad light range that were sampled in theWestern Carpathians Mountains(Slovakia).Important Findings We found that:(i)intraspecific shoot-level biomass allocational trade-offs differ from those reported interspecifically and that(ii)long and short shoots differ in biomass allocation scaling coefficients.Allometric relationships with slopes statistically smaller than 1.0 or higher than-1.0,were found between SM and LM and between mean leafing intensity and individual leaf mass,respectively,in long shoots.In contrast,isometric scaling was found in short shoots.This suggests that leaf mass in short shoots is unaffected by shoot stem mass,in contrast to long shoots.Short shoots also had a larger fraction of biomass allocated to leaves.Beech shoots,as has been observed in other shoot dimorphic species,are specialized,with short shoots specializing in carbon gain and long shoots in space acquisition.A greater shift in LM than in SM among species during speciation shifting from allometric intraspecific relationships to an isometric interspecific scaling relationship between those traits could explain the discrepancies between the outputs of the present intraspecific study and others similar studies.This study draws attention to the importance of considering shoot types in future studies dealing with allocation rules in species with dimorphic shoots.Benjamín Jarcuska Ruben Milla 2012Journal of Plant Ecology2012,5,4:2

14Three-dimensional analysis of the physiological foramen geometry of maxillary and mandibular molars by means of micro-CT显示文摘The aim of this study was to investigate the physiological foramen diameter, shape and distance between physiological and anatomical apex of maxillary and mandibular first and second molars. Accurate knowledge of the physiological foramina morphology; thus, inherent mechanical shaping technical hindrances, is decisive when taking the corresponding root canal final preparation decision. The morphological dimensions of a total of 1 727 physiological foramina were investigated by means of micro-computed tomography. Mean narrow and wide(to a high number, oval) diameters of the physiological foramen were 0.24,0.22 and 0.33 mm and 0.33, 0.31 and 0.42 mm in mesiobuccal(MB), distobuccal(DB) and palatal(P) roots in maxillary first molars; 0.24, 0.22 and 0.33 mm and 0.41, 0.33 and 0.44 in MB, DB, and P roots in maxillary second molars. Mandibular first molars showed mean narrow and wide diameters of 0.24 and 0.30 mm and of 0.39 and 0.46 mm in mesial(M) and distal(D)roots; second mandibular molars showed 0.25 and 0.31 mm and 0.47 mm in M and D roots. The mean distance between the physiological foramina and anatomical apex was 0.82, 0.81 and 1.02 mm and 0.54, 0.43 and 0.63 mm in MB, DB and P roots of the maxillary first and second molars, respectively. A mean distance of 0.95 mm(M) and 1.05 mm(D) in the first and0.78 mm(M) and 0.81 mm(D) in the second mandibular molars was observed. Based on the results obtained, assumable recommendations for final preparation size of the physiological foramen were calculated. However, when taking into consideration, the resulting standard deviations of marginal errors must be cautiously considered when taking a final decision in clinical endodontic treatment.Thomas Gerhard Wolf Frank Paqué Michael Sven Patyna Brita Willershausen Benjamín Briseno-Marroquín 2017International Journal of Oral Science2017,9,3:4
15Root canal morphology and configuration of 123 maxillary second molars by means of micro-CT显示文摘The aim of this study was to investigate the root canal configuration, accessory canals and number of main foramina of 123 maxillary second molars by means of micro-computed tomography. The teeth were scanned and reproduced with 3D software imaging. The root canal configuration and number of main foramina were evaluated by means of a four-digit system. The morphological complexity of human maxillary second molars is depicted by the number of accessory and connecting canals. The most frequently observed root canal configurations in the mesiobuccal root were 2-2-2/2(19.5%), 2-2-1/1(14.6%) and 2-1-1/1(13.0%). A 1-1-1/1 configuration was observed in 93.5% and in 96.7% in the distobuccal and palatal roots, respectively. The MB1 root canal had one accessory canal(18.7%), and 8.9% of the MB2 root canal had one or two accessory canals. The distobuccal(11.3%) and palatal(14.6%) root canals had at least one accessory canal, and connecting canals were observed in16.3% of mesiobuccal roots. The MB1, MB2, distobuccal and palatal root canals had one main foramen in 99.2%, 43.1%,98.4% and 99.2% of samples, respectively. In the mesiobuccal root, one accessory foramen was detected in 14.6%, two were detected in 7.3%, and three were detected in 5.7%. The distobuccal root showed one or two accessory foramina in 9.1% of samples. The root canal configuration of maxillary second molars is quite heterogeneous; the mesiobuccal root has predominantly two root canal entrances(58.4%, 1 in 41.1%) with one main foramen(54.4%). Two main foramina were observed in 43.0%. Morphological variations, connecting and accessory canals were observed in all apical thirds.Thomas Gerhard Wolf Frank Paqué Anja-Christin Woop Brita Willershausen Benjamín Briseno-Marroquín 2017International Journal of Oral Science2017,9,1:3

18Simultaneous analysis of the intestinal parasites and diet through eDNA metabarcoding显示文摘Agricultural expansion and intensification are having a huge impact on plant and arthropod diversity and abun-dance,affecting food availability for farmland birds.Difficult food access,in turn,can lead to immunosuppression and a higher incidence of parasites.In the studies designed to examine changes in the diet of birds and their par-asites,metabarcoding is proving particularly useful.This technique requires mini-barcodes capable of amplifying the DNA of target organisms from fecal environmental DNA.To help to understand the impact of agricultural expansion on biodiversity,this study sought to design and identify mini-barcodes that might simultaneously as-sess diet and intestinal parasites from the feces of farmland birds.The capacity to identify diet and parasites of 2 existing and 3 newly developed mini-barcodes was tested“in silico”in relation to the behavior of a reference eukaryotic barcode.Among the newly designed mini-barcodes,MiniB18S_81 showed the higher taxonomic cover-age of eukaryotic taxa and a greater amplification and identification capacity for diet and parasite taxa.Moreover,when it was tested on fecal samples from 5 different steppe bird species,MiniB18S_81 showed high taxonomic resolution of the most relevant diet and parasite phyla,Arthropoda,Nematoda,Platyhelminthes,and Apicomplexa at the order level.Thus,the mini-barcode developed emerges as an excellent tool to simultaneously provide detailed information regarding the diet and parasites of birds,essential for conservation and management.Xabier CABODEVILLA Benjamín Juan GÓMEZ-MOLINER Naiara ABAD María JoséMADEIRA 2023Integrative Zoology2023,18,3:1
