Neanderthals of Porto Selvaggio in southern Italy: lithic industry of Grotta Torre dell'Alto (Nardò, Lecce)
(Journal of Quaternary Science, 2021-10-18)Porto Selvaggio in southern Italy is where the Uluzzian culture was first identified and documented, providing key insights into the transition from the Middle to the Upper Paleolithic. The area has also yielded evidence ... -
Near streambed flow shapes microbial guilds within and across trophic levels in fluvial biofilms
(Limnology and Oceanography, 2020)Flow is an important physical driver of biofilm communities. Here, we tested the effects of the near bed flows in two mountainous stream reaches on the structure of biofilm microbial guilds (autotrophs, heterotrophic ... -
Neogene hyperaridity in Arabia drove the directions of mammalian dispersal between Africa and Eurasia
(Communications Earth & Environment, 2021-05-18)The evolution of the present-day African savannah fauna has been substantially influenced by the dispersal of Eurasian ancestors into Africa. The ancestors evolved endemically, together with the autochthonous taxa, into ... -

Neue Untersuchungen über Bau und Leben der Bernsteinkiefern (Pinus succinifera (Conw.) emend.) - ein Beitrag zur Paläohistologie der Pflanzen : mit 1 Tabelle
(Geologisches Jahrbuch / Beihefte ; Heft 45)Der Gewebeaufbau der Zweige der tertiären Bernsteinbäume wurde mit Hilfe der Lackfilmmethode (E. Voror) untersucht. Verschiedene hundert Holz-, Rinden- und Borkeneinschlüsse des baltischen Bernsteins wurden in drei ... -
New and revised small shelly fossil record from the lower Cambrian of northern Iran
(Papers in Palaeontology, 2021-08-19)Small shelly fossils (SSFs) are highly informative of the ‘Cambrian explosion’. Their palaeobiodiversity has been documented from lower Cambrian deposits worldwide but it remains elusive in areas such as Iran, despite this ... -
New insights into Southern Caucasian glacial–interglacial climate conditions inferred from Quaternary gastropod fauna
(Journal of Quaternary Science, 2020)In the present study, we performed gastropod analyses on loess–palaeosol sequences from northeast Armenia (Southern Caucasia) covering at least three glacial–interglacial cycles. The elaborated ecostratigraphy shows ... -
Niphargus-Thiothrix associations may be widespread in sulphidic groundwater ecosystems: evidence from southeastern Romania.
(Molecular ecology, 2014-03-01)Niphargus is a speciose amphipod genus found in groundwater habitats across Europe. Three Niphargus species living in the sulphidic Frasassi caves in Italy harbour sulphur-oxidizing Thiothrix bacterial ectosymbionts. These ... -
Non-lithistid fossil Demospongiae - origins of their palaeobiodiversity and highlights in history of preservation
(Systema Porifera : a guide to the classification of sponges. Vol. 1: Introductions and Demospongiae, 2002)Available evidence suggests that the first demosponges occur in the Late Proterozoic, with forms characterized by bundles of long monaxonic spicules. In the Middle Devonian the first modern forms of Dendroceratida, ... -
Nonmarine Ostracoda as proxies in (geo‐)archaeology — A review
(Geoarchaeology, 2022-05-03)Ostracods as bioindicators are extremely useful for reconstructing palaeoenvironment and palaeoclimate and can also indicate the provenance of sediments and materials, for example, in studies on ancient commercial networks. ... -
Normalograptus kufraensis, a new species of graptolite from the western margin of the Kufra Basin, Libya
(Geological Magazine, 2013)Normalograptus kufraensis sp. nov. occurs as monospecific assemblages in the Tanezzuft Formation at the western margin of the Kufra Basin (Jabal Eghei), southern Libya. These graptolites have parallel-sided rhabdosomes ... -
Not herbs and forbs alone: pollen‐based evidence for the presence of boreal trees and shrubs in Cis‐Baikal (Eastern Siberia) derived from the Last Glacial Maximum sediment of Lake Ochaul
(Journal of Quaternary Science, 2021-03-16)A new accerator mass spectrometry (AMS)‐dated sedimentary record from Lake Ochaul (54°14′N, 106°28′E; 641 m a.s.l.) in Eastern Siberia covers the interval from ca. 27 850 to 20 400 cal a bp at ca. 180‐year resolution and ... -
NPP-ID: Non-Pollen Palynomorph Image Database as a research and educational platform
(Vegetation History and Archaeobotany, 2021-08-30)Non-pollen palynomorphs (NPPs) form a large group of biological objects found in palynological slides besides pollen grains. This includes various remains of algae and fungi, shells, resting stages and eggs of invertebrates, ... -
Nutrient and Silicon Isotope Dynamics in the Laptev Sea and Implications for Nutrient Availability in the Transpolar Drift
(Global Biogeochemical Cycles, 2022-09-23)Realistic prediction of the near‐future response of Arctic Ocean primary productivity to ongoing warming and sea ice loss requires a mechanistic understanding of the processes controlling nutrient bioavailability. To ... -
Nutrient co‐limitation in the subtropical Northwest Pacific
(Limnology and Oceanography Letters, 2021-08-17)Nutrients limiting phytoplankton growth in the ocean are a critical control on ocean productivity and can underpin predicted responses to climate change. The extensive western subtropical North Pacific is assumed to be ... -
Nutrient regulation of late spring phytoplankton blooms in the midlatitude North Atlantic
(Limnology and Oceanography, 2019)The duration and magnitude of the North Atlantic spring bloom impacts both higher trophic levels and oceanic carbon sequestration. Nutrient exhaustion offers a general explanation for bloom termination, but detail on which ... -
