Palynology: principles and applications

Palynology , scientific discipline concerned with the study of plant pollen , spores , and certain microscopic planktonic organisms , in both living and fossil form. The field is associated with the plant sciences as well as with the geologic sciences, notably those aspects dealing with stratigraphy , historical geology , and paleontology. Palynology also has applications in archaeology , forensic science and crime scene investigation, and allergy studies. Accordingly, the scope of palynologic research is extremely broad, ranging from the analysis of pollen morphology with electron microscopes to the study of organic microfossils palynomorphs extracted from ancient coals. As pollen and spores are produced in large numbers and dispersed over large areas by wind and water, their fossils are recoverable in statistically significant assemblages in a wide variety of sedimentary rocks.

Palynology - the study of micro organic material such as spores, pollen, dinoflagellates and microfossils 1 - is a method employed by a range of disciplines all concerned with the environment. It is not an undergraduate degree subject due to its limited scope, and though there are some Master's programmes in most countries, those wishing to enter into the field may approach the subject from many different directions. One of the most fascinating aspects - and perhaps underappreciated by most people - is how landscapes change over time in terms of the plant life that grows there. We can learn much about the landscape itself, the natural and human history of that landscape including the changes it has undergone as a result of natural or human processes , and of the changing climate and what impact that has upon plant life. Flora - trees, flowers, grasses, mosses, lichen and even fungi have environmental conditions that they prefer and other conditions in which they will not survive for very long. Moving from a dry to wet climate or vice versa , from temperate to ice age or vice versa and even whether and when a piece of land was once tidal salt marsh but is now pasture, can all affect the makeup of the landscape's flora.

John F. AAPG Bulletin ;; 44 1 : Palynology is the study of pollen and spores. Throughout much of geologic time, these microscopic plant particles have been accumulating in sediments. Their recovery from sediments enables the palynologist to establish correlation based on time equivalence. A brief sketch of the development of palynology is followed by an examination of the basic principles of the field.

A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition i. It is the science that studies contemporary and fossil palynomorphs , including pollen , spores , orbicules , dinocysts , acritarchs , chitinozoans and scolecodonts , together with particulate organic matter POM and kerogen found in sedimentary rocks and sediments. Palynology does not include diatoms , foraminiferans or other organisms with siliceous or calcareous exoskeletons.

The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e. The journal especially encourages the publication of articles in which palaeobotany and palynology are applied for solving fundamental geological and biological problems as well as innovative and interdisciplinary approaches.


Guide for Authors

What Is Palynology? Palynology is the study of plant pollen, spores and certain microscopic plankton organisms collectively termed palynomorphs in both living and fossil form. Botanists use living pollen and spores actuopalynology in the study of plant relationships and evolution, while geologists palynologists may use fossil pollen and spores paleopalynology to study past environments, stratigraphy the analysis of strata or layered rock historical geology and paleontology. The oil industry is credited with demonstrating the usefulness of palynomorphs in the study of stratigraphic sequences of rocks and the potential for oil and gas exploration.

Palynology, which is the study of pollen and spores in an archaeological or geological context, has become a well-established research tool leading to many significant scientific developments. The term palynomorph includes pollen of spermatophytes, spores of fungi, ferns, and bryophytes, as well as other organic-walled microfossils, such as dinoflagellates and acritarches. Advances in plant genomics have had a high impact on the field of forensic botany. Forensic palynology has also been used and applied more recently to criminal investigation in a meaningful way. However, the use of pollen DNA profiling in forensic investigations has yet to be applied. There were earlier uses of dust traces in some forensic analyses that considered pollen as a type of botanical dust debris.

Быть может, смерть Танкадо в публичном месте была необходимостью, однако публика возникла чересчур. Халохот был вынужден скрыться, не успев обыскать убитого, найти ключ.

Он снова ответил Да. Мгновение спустя компьютер подал звуковой сигнал. СЛЕДОПЫТ ОТОЗВАН Хейл улыбнулся.

 Так почему… чего же он так долго ждал. - Потому что ТРАНСТЕКСТ никак не мог вскрыть этот файл. Он был зашифрован с помощью некоего нового алгоритма, с которым фильтры еще не сталкивались.


Двухцветный посмотрел на часы Беккера.

Большой Брат, или Брат, как его обычно называла Мидж, - это аппарат Сентрекс-333, размещавшийся в крохотном, похожем на подсобку кабинетике рядом с директорскими апартаментами. Большой Брат был частью мира, в котором царила Мидж. Он получал информацию со 148 камер кабельного телевидения, 399 электронных дверей, 377 устройств прослушивания телефонов и еще 212 жучков, установленных по всему комплексу АНБ. Директора АН Б дорого заплатили за осознание того факта, что двадцать шесть тысяч сотрудников не только огромная ценность, но и источник больших неприятностей.

А я-то думал, что ты будешь это отрицать. - Подите к черту. - Очень остроумно. - Вы болван, Стратмор, - сказал Хейл, сплюнув.  - К вашему сведению, ваш ТРАНСТЕКСТ перегрелся.

Прихожане могли понять нетерпение этого человека, стремившегося получить благословение, но ведь существуют строгие правила протокола: подходить к причастию нужно, выстроившись в две линии. Халохот продолжал двигаться. Расстояние между ним и Беккером быстро сокращалось.

Голос его звучал спокойно и чуточку игриво.  - Откроем пачку тофу. - Нет, спасибо.  - Сьюзан шумно выдохнула и повернулась к.  - Я думаю, - начала она, -что я только… -но слова застряли у нее в горле.

Ярко освещенное помещение аэровокзала сияло стерильной чистотой. Здесь не было ни души, если не считать уборщицы, драившей пол.
