Bryozoan Studies 2019
BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

Devonian Bryozoans of the Holy Cross Mountains, Poland
ACT A PAL A EON T 0 LOG ICA POLONICA Vol. XVIII 1973 No.4 MARIA KIEPURA DEVONIAN BRYOZOANS OF THE HOLY CROSS MOUNTAINS, POLAND. PART II. CYCLOSTOMATA AND CYSTOPORATA Abstract. - Descriptions are given of 33, species of Middle Devonian Bryozoa from the Holy Cross Mts., belonging to the orders Cyclostomata and Cystoporata. Cyclo stomata are represented by 26 species (4 new: Corynotrypa (Corynotrypa) skalensis, C. (C.) basiplata, Stomatopora varigemmata and Diversipora bitubulata n. gen.). Cystoporata are represented by 7 new species: Ceramoporella orbiculata, C. grandi cystica, Favositella integrimuralis, Fistulipora boardmani, F. emphantica, Cyclotrypa nekhoroshevi and Fistuliramus astrovae. The systematic assignment of the genus Hederella Hall, 1881 has been discussed and the "tabulate-like" microstructure of the zooecial walls of this genus examined. In addition, the epifauna and associated assemblages have been characterized as well as the geological and palaeoecological conditions in which the described Bryozoa occurred. INTRODUCTION Among the Middle Devonian Bryozoa of the Holy Cross Mts., the present author has, up to now, described Ctenostomata (Kiepura, 1965). The present paper is a continuation of her investigations on the Middle Devonian Bryozoa of this region and contains descriptions of 33 species belonging to 9 genera of the orders Cyclostomata and Cystoporata occur ring in the Grzegorzowice - Skaly profile. The bryozoan collection of the Palaeozoological Institute of the Polish Academy of Sciences also contains a rich material representing the orders Trepostomata and Cryptostomata from the Middle Devonian of the Holy Cross Mts., which will be described at a future date. The material described in the present paper was collected by the author during several years of fieldwork (1950-1954). -

We examined the type specimens and historical collections holding puzzling Atlantic and Mediterranean material belonging to the genus Schizoretepora Gregory, 1893. We performed a detailed study of the colonial characters and re-describe the resulting species and those that have rarely been found or have poor original descriptions. As a result of this revision, nine species are found in the northeast Atlantic and Mediterranean. Six of them are re-described and illustrated: S. aviculifera (Canu & Bassler, 1930), S. calveti d’Hondt, 1975, S. imperati (Busk, 1884), S. sp. nov.? (= S. -

Relation of Form to Life Habit in Free-Living Cupuladriid Bryozoans

Today, the free-living bryozoans often dominate epi- benthic faunal communities in these expansive habi- tats, yet their biology and ecology remain poorly un- derstood. This study examines their unique mode of life by exploring the relationship between form and function in the free-living Cupuladriidae of tropical America. Cupuladriid species occupy distinct niches in water depth and sediment type, and these vari- ables correlate with a variety of morphological traits amongst species, thereby helping formulate hypothe- ses on functional morphology. These hypotheses were tested with disturbance, burial and mobility experi- ments. Species deal both passively and actively with Colonies of free-living bryozoans dig to the surface using disturbance and burial.

Resampling Methods in Paleontology
RESAMPLING METHODS IN PALEONTOLOGY MICHAŁ KOWALEWSKI Department of Geosciences, Virginia Tech, Blacksburg, VA 24061 and PHIL NOVACK-GOTTSHALL Department of Biology, Benedictine University, 5700 College Road, Lisle, IL 60532 ABSTRACT.—This chapter reviews major types of statistical resampling approaches used in paleontology. They are an increasingly popular alternative to the classic parametric approach because they can approximate behaviors of parameters that are not understood theoretically. The primary goal of most resampling methods is an empirical approximation of a sampling distribution of a statistic of interest, whether simple (mean or standard error) or more complicated (median, kurtosis, or eigenvalue). This chapter focuses on the conceptual and practical aspects of resampling methods that a user is likely to face when designing them, rather than the relevant math- ematical derivations and intricate details of the statistical theory. The chapter reviews the concept of sampling distributions, outlines a generalized methodology for designing resampling methods, summarizes major types of resampling strategies, highlights some commonly used resampling protocols, and addresses various practical decisions involved in designing algorithm details. A particular emphasis has been placed here on bootstrapping, a resampling strategy used extensively in quantitative paleontological analyses, but other resampling techniques are also reviewed in detail. In addition, ad hoc and literature-based case examples are provided to illustrate virtues, limitations, and potential pitfalls of resampling methods. We can formulate bootstrap simulations for almost any methods from a practical, paleontological perspective. conceivable problem. Once we program the computer In largely inductive sciences, such as biology or to carry out the bootstrap replications, we let the com- paleontology, statistical evaluation of empirical data, puter do all the work.
