Abstract The research was carried out in three types of habitats located in the seasonally flooded area of the Vistula River within Wielka Kępa Ostromecka Reserve: Salicetum albo-fragilis, Fraxino-Alnetum and Populetum albae. In the soil of Salicetum albo-fragilis Veigaia nemorensis and Trichouropoda ovalis were abundant, while Fraxino-Alnetum was dominated by Rhodacarellus silesiacus, and Populetum albae was overwhelmed by Rhodacarellus silesiacus and Dinychus inermis. Only between the Mesostigmata communities populating Fraxino-Alnetum and Populetum albae there were no statistically significant differences recorded in the distribution of abundance. The most similar, from the qualitative, quantitative and qualitative-quantitative point of view were Mesostigmata communities inhabiting Fraxino- Alnetum and Populetum albae. The numerous occurrence of Rhodacarellus silesiacus population in the soil of Fraxino-Alnetum and Populetum albae is most probably the result of succession changes within those habitats, and the species itself can be seen as an indicator of those habitats undergoing the process of a riparian forest transforming into an oak-hornbeam forest vegetation type.

Resumen:Antecedentes y Objetivos: Son pocos los trabajos florísticos que se han publicado sobre licofitas y helechos (pteridofitas en conjunto) de Puebla, México, por lo que se considera muy probable que la riqueza de especies en el estado sea mayor a la que se tiene documentada hasta el momento.El objetivo de este trabajo es reportar nuevos registros de este grupo de plantas para la entidad, incluyendo su distribución municipal y altitudinal, así como el tipo de vegetación en que se presentan.Métodos: De 2010 a 2018 se efectuaron diversos viajes de recolección a distintas localidades de Puebla, durante los cuales se recolectaron y herborizaron ejemplares de licofitas y helechos, que fueron identificados y depositados en el Herbario de la Universidad Autónoma Metropolitana-Iztapalapa (UAMIZ). La información generada se confrontó con la lista de especies reportadas en la literatura para la entidad, lo que permitió reconocer los nuevos registros.Resultados clave: Se documenta por primera vez para Puebla la presencia de 32 especies y un híbrido de licofitas y helechos, la mayoría de las cuales pertenecen a las familias Pteridaceae, Dryopteridaceae y Aspleniaceae, crecen en bosque mesófilo de montaña y vegetación derivada de bosque tropical perennifolio, entre 250 y 2500 m de altura.Conclusiones: Los nuevos registros incrementan de 335 a 367 el número de especies de licofitas y helechos que habitan en el estado de Puebla y ponen en evidencia la necesidad de continuar con el trabajo de exploración en la entidad.Palabras clave: bosque mesófilo de montaña, bosque tropical perennifolio, pteridofitas, riqueza, tipo de vegetación.Abstract:Background and Aims: There are few published floristic contributions about the lycophytes and ferns (pteridophytes) from Puebla, so it is considered very likely that the specific richness of this group in the state is greater than what has been documented currently. The goal of this paper is to document the new records of this plant group for the state, including information about their municipal and altitudinal distribution and the type of vegetation they inhabit.Methods: Between 2010 and 2018, several collection trips to different localities of the state of Puebla were made to collect specimens of lycophytes and ferns. The material was identified and deposited in the Herbarium of the Universidad Autónoma Metropolitana-Iztapalapa (UAMIZ). The information obtained was compared with the list of species of Puebla reported in the literature, allowing recognition of the new records.Key results: The presence of 32 species and a hybrid of lycophytes and ferns was documented for the first time for Puebla, most of which belong to the families Pteridaceae, Dryopteridaceae and Aspleniaceae, growing in cloud forest and vegetation derived from tropical evergreen forest, betweenelevations of 250 and 2500 m.Conclusions: The new records increase the number of species of lycophytes and ferns reported for Puebla from 335 to 367 and highlight the need to continue with the exploration and field work in the state.Key words: cloud forest, pteridophytes, richness, tropical evergreen forest, vegetation type.

Abstract The purpose of this study was to determine the habitat characteristics of the Sumatran Elephant in the Serbajadi District Forest. Data collection by looking at the use of habitat which is characterized by the distribution of faeces found in various habitat units in the home range of the Sumatran Elephant. The method used is observation with a track with a size of 3,600 m which is divided into 20 observation plots with a distance between plots of 100 m. The data obtained in the field were analyzed descriptively and presented in tabular form. The results of this study indicate that the Habitat Characteristics of the Sumatran Elephant in the Serbajadi District Forest chose habitat units with very dense canopy cover (>75%), moderate feed availability (26-50%), rare mineral source trees availability (< 3 trees/plot). availability of sparse scrubbing trees (<3 trees/plot), close to primary forest (0-500 m), low land elevation (0- 400 masl), gentle slope (0-20°), close to water sources (0-250m). Secondary forest/vegetation type and frequency of habitat use based on the findings of faeces that the Sumatran elephant most frequently visited was secondary forest than primary forest because the secondary forest was for feeding activities while the primary forest was used for resting and reproduction.

Botanical remains were identified from 27 lots from the Washington Square Mound site (41NA49). The primary occupation at the site is Middle Caddo period in age. The first pooled set of calibrated radiocarbon dates from the site fell into the period A.D. 1268-1302, while a recent set of five calibrated dates from samples of plant remains discussed in this article range from A.D. 1279 + 17; (2) A.D. 1358 + 57; and three dates on charred corn from Features 36, 81, and 86 range from as early as A.D. 1394 to as late as A.D. 1437. These dates as a group fall in the Middle Caddo period; there is limited evidence at the site for other, smaller occupations, including Late Caddo and Late Woodland/Early Caddo. At least three mounds were visible in the nineteenth century. Much of the site was never plowed, a situation that has resulted in intact shallow deposits and unusually large pottery sherds, although a high school has been built over parts of the non-mound site area. Labels of botanical lots that included excavation dates indicate a range from 1979 to 1983, associating the botanical remains with Stephen F. Austin State University Field School excavations that took place during this time. At least nine features are represented in the botanical lots. Four are described as charcoal-filled pits, one as a pit, and one as a post mold. Feature 36 was a corn cob concentration . Botanical lots for Features 62, 81, and 199 are also present. The Washington Square Mound site is situated in the city of Nacogdoches, Texas, on an interfluve between Banita Creek and La Nana Creek, which drain into La Nana Bayou and the Angelina River. The area lies squarely in the Pineywoods ecological zone, the westernmost extension of the great Southeastern Evergreen Forest that reaches across the southeastern United States to the Atlantic coast (Braun 2001:281). The dominant vegetation type in an upland area such as Washington Square during presettlement times would have been a shortleaf pine community, where shortleaf pines (Pinus echinata) share dominance with dry-site oaks such as southern red oak (Quercus falcata), post oak (Q. stellata), and blackjack oak (Q. marilandica), hickories (Carya spp.), and elms (Ulmus spp.) Springs and marshy areas nearby would have offered aquatic and wetland plants such as river cane (Arundinaria gigantea). A spring-fed pond is reported to have existed north of the site, and a marshy area to the southwest. Pollen studies indicate that use of the modern and recent vegetation is appropriate for understanding the plants and attendant animal resources available to occupants of the sites during prehistoric times. Some fluctuations in rainfall and temperature have taken place, however. In addition, more frequent fires would have made the understory in the uplands less prominent than today. Early explorers in East Texas and other parts of the Eastern Woodlands noted the open, park-like nature of many woodlands.
