    ABSTRACT: Upland peatlands in the UK are important sources of palaeoenvironmental information, providing context to human land use in upland areas. Land management practices, particularly over the last 150 years have resulted in damage to the integrity of this palaeoenvironmental record. This study focuses on the effects of drainage on the condition of pollen remains within upland peat deposits using a case study from Exmoor, southwest England. Water-table monitoring and coring across three mires enabled the effects of water-table draw-down on the condition of pollen remains within the peat matrix to be assessed. Our results show that peatland drainage, which has taken place over the last 60–150 years, caused significant localised water-table draw-down. A detailed pollen condition survey across seven coring sites demonstrates that pollen within the peat is damaged as a consequence. However, pollen is rarely so damaged that counted pollen assemblages are unreliable. Correspondence between pollen condition and past climate shifts and periods of enhanced human activity, suggests that recent damage to pollen caused by peatland drainage is superimposed on damage caused by other factors throughout the period of peat accumulation.

    ABSTRACT: In order to examine pollen deterioration in mangrove sediments, surface sediment samples were collected from 4 different mangrove communities, placed in nylon gauze bags, and then buried back into their own vegetation in October 2010. At periods of 2, 4, and 6 months after burial, sediment bags were retrieved and examined. At each recovery, palynomorph percentages and concentrations were calculated as a means to investigate degradation rates of deposited palynomorphs and some physical factors affecting their preservation. It was found that although mangrove sediments are assumed to represent perfect depositional environments for the preservation of mangrove pollen due to the anoxic conditions, a high potential for loss of pollen was observed. Palynomorphs decayed more rapidly in the Ceriops tagal – Bruguiera spp. community, whereas this process seems to proceed at a slower rate in the Rhizophora apiculata – Bruguiera spp. community, possibly controlled by differences in sediment pH, salinity, grain size, and organic matter. The good pollen preservation of Rhizophora apiculata and Sonneratia alba in their own plant communites allow them to act as useful indicators of the forest communities in which they are dominant. On the other hand, quantitative compositional reliabilities of pollen from Avicennia alba, Bruguiera spp., and Ceriops tagal, tended to weaken by their progressive deterioration and poor preservation. However, a long term-experiment is still necessary to achieve a more accurate estimation of biases from such important taphonomic factors.

    ABSTRACT: The digitization of pollen grain images would permit the creation of a semi-automated system that could aid the expert palynologists in pollen classification. It would reduce cost and time-to-answer as well as improve analyst productivity. These issues are particularly critical in forensic applications. There are numerous factors that should be considered when establishing a digital database intended for semi-automated pollen classification. This paper explores a number of these issues through computer vision and machine learning assessments. The main topics evaluated are morphologically similar species-level classification, optimal training data size, how best to utilize three-dimensional data, accuracy changes due to the availability of metadata, i.e., fluctuations in analysts' confidence in taxa labeling, and using fossil data to classify modern data. This is the first known application of training on fossil data to classify modern taxa. Performances of 95.4% and 93.8% correct classification were achieved on two distinct sets of morphologically similar species-level data, surpassing previous records. We determined that a minimum of 5–10 training images per class was required to yield reasonable performance. Additionally, we established that all depth dimension slices associated with each grain were required to yield the best performance possible. Lastly, the error rate doubles due to decreasing analyst confidence and almost triples when using data from grains of varying ages, further solidifying the importance of comprehensive metadata.

    ABSTRACT: Pollen productivity estimates (PPE) are used to quantitatively reconstruct variations in vegetation within a specific distance of the sampled pollen archive. Here, for the first time, PPEs from Siberia are presented. The study area (Khatanga region, Krasnoyarsk territory, Russia) is located in the Siberian Sub-arctic where Larix is the sole forest-line forming tree taxon. Pollen spectra from two different sedimentary environments, namely terrestrial mosses (n = 16) and lakes (n = 15, median radius ~ 100 m) and their surrounding vegetation were investigated to extract PPEs. Our results indicate some differences in pollen spectra between moss and lake pollen. Larix and Cyperaceae for example obtained higher representation in the lacustrine than in terrestrial moss samples. This highlights that in calibration studies, modern and fossil datasets should use archives of similar sedimentary origin. Results of an Extended R-Value model were applied to assess the relevant source area of pollen (RSAP) and to calculate the PPEs for both datasets. As expected, the RSAP of the moss samples was very small (about 10 m) compared to the lacustrine samples (about 25 km). Calculation of PPEs for the six most common taxa yielded generally similar results for both datasets. Relative to Poaceae (reference taxon, PPE = 1) Betula nana-type (PPEmoss: 1.8, PPElake: 1.8) and Alnus fruticosa-type (PPEmoss:6.4, PPElake:2.9) were overrepresented while Cyperaceae (PPEmoss:0.5, PPElake:0.1), Ericaceae (PPEmoss: 0.3, PPElake < 0.01), Salix (PPEmoss:0.03, PPElake < 00.1) and Larix (PPEmoss: < 0.01, PPElake:0.2) were under-represented in the pollen spectra compared to the vegetation in the RSAP. The estimation for the dominant tree in the region, Larix gmelinii, is the first published result for this species, but needs to be considered very preliminary. The inferred sequence from over- to under-representation is mostly consistent with results from Europe; however, the absolute values show some differences. Gathering vegetation data was limited by the remoteness of our study area and a lack of high-resolute satellite imagery and vegetation maps. Our estimate may serve as a first reference to strengthen future vegetation reconstructions in this climate-sensitive region.

    ABSTRACT: The purpose of this work was to study in detail with TEM the successive stages of pollen wall and tapetum development in Dianthus deltoides and to clarify the mechanisms underlying the developmental processes. At the young tetrad stage a thin glycocalyx layer is poorly structured, being a mixture of glycoproteins, secreted by Golgi vesicles through the process of exocytosis. At the middle tetrad stage the plasma membrane acquires a deeply invaginated profile as a result of self-assembly cellular tensegrity, and its pinnacles determine the sites of the future spines. Then, lipoid sporopollenin (SP) precursors and monomers are added into the periplasmic space. The concentrations of all substances in the periplasmic space are under genome control. As a consequence of self-assembly hydrophilic–hydrophobic interactions, “islets” of osmiophilic lipoid substances occur in the glycocalyx mixture, first as spherical units, then as plates, with further lateral growth and the appearance of the hexagonal reticulate pattern of the future tectum. At maturity, the reticulate pattern is not evident. At the late tetrad stage spines are initiated as outgrowths of the glycocalyx in the form of cone-like liquid-crystal “skeletons”, the latter accumulate SP. Columellae are initiated very late in ontogeny, at the stage when the tetrads separate into monads, on the base of the glycocalyx rod-like units — the cylindrical micelles. The first endexine lamella with a central white line appears at the young free microspore stage on the base of laminate micelles. The second endexine layer is granulate and appears on the base of spherical micelles. Pollen grains are polyporate with aperturate membranes, consisting of lamellate endexine-1 and an underlying dilation – oncus – comprising granulate endexine-2. The pore membranes bear large cupola-like tectal spines. The tapetum secretes a peri-tapetal membrane with Ubisch bodies, first with clusters of globules, then exine-like spines on the top of clusters. These Ubisch bodies mimic the pattern of the exine. The entire sequence of developmental events can be explained as the development of a self-assembling system under initial genomic regulation.

    ABSTRACT: The subfamily Fumarioideae is the most diversified group of the Papaveraceae family, a eurypalinous group whose pollen information has classically been used for studying systematic issues. In this paper we present a study of pollen morphology and development of the pollen wall in most of the Fumarioideae genera excluding Hypecoum. We describe a high variability in pollen grain ornamentation and in aperture shape and number among genera of the subfamily. Remarkable features of the pollen-wall layer development in Fumarioideae are a lamellated foot layer at the young microspore stage and a granular infratectum. In the apertures, the aperture membrane formed by ectexine is absent for the subtribe Fumariinae, and the ultrastructure of the exinous oncus shows that the endexine is arranged in three different ways among the Fumarioideae representatives. From vacuolate microspore stage onward the apertures of most Fumarioideae genera are covered by a fluffy plug, while during young bicellular stage the intine under the apertures develops from the material that accumulated in the periplasmic space. We have identified significant differences between the pollen features of the tribe Fumarieae and the tribe Hypecoeae, such as psilate exine and granular infratectum. The presence of atypical pollen features in Fumarioideae is discussed within the framework of current knowledge of pollen wall development, highlighting their implications for a better understanding of pollen wall evolution.
