We test the hypothesis that tree species previously known as Deinbollia sp. 2 . is a new for science. formally characterise and name this onanae (Sapindaceae-Litchi clade) we discuss it in context of assemblage montane Cameroon Highlands West-Central Africa. The shade-bearing, non-pioneer understorey forest reaching 15 m high trunk diameter can attain over 40 cm at 1.3 above ground. Seed dispersal has been recorded by chimpanzees ( Pan troglodytes ellioti ) putty-nose monkeys Cercopithecus...
Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series from across globe makes these freely available community. MASTREE+ includes 73,828 georeferenced observations annual (e.g. seed fruit counts) perennial...
Arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) associations are critical for host-tree performance. However, how correlate with the latitudinal tree beta-diversity remains untested. Using a global dataset of 45 forest plots representing 2,804,270 trees across 3840 species, we test AM EcM contribute to total its components (turnover nestedness) all trees. We find rather than predominantly decreasing turnover increasing nestedness latitude, probably because wide distributions do not...
Abstract A survey of allozyme diversity within and between populations Silene acaulis from Spitsbergen, Norway, Iceland Scotland, showed that the high Arctic (Spitsbergen, > 76°N) contained levels were genetically similar to more southern locations. Indirect measures gene flow ( Nm ), calculated Wrigh's F indicated there had been extensive Spitsbergen some Norwegian populations. restriction site analysis chloroplast DNA (cpDNA) in S. revealed all a single identical cpDNA haplotype, except...
Abstract: Seed-dispersal ecology in tropical montane forests (TMF) differs some predictable ways from lowland (TLF). Environmental, biogeographic and biotic factors together shape dispersal syndromes which turn influence forest structure community composition. Data on diaspore traits along five elevational gradients Thailand, the Philippines, Tanzania, Malawi Nigeria showed that size decreases with increasing altitude, fleshy fruits remain most common fruit type but relative proportion of...
We conducted a multi-isotope study of five fifth-century AD cemeteries in modern-day Hungary to determine relationships between nomadic-pastoralist incomers—the historically documented Huns and other nomadic groups—and the sedentary agricultural population late Roman province Pannonia. Contemporary historical sources describe this relationship as adversarial destructive for population, but archaeological evidence indicates high levels hybridity different groups. undertook carbon, nitrogen,...
Local factors can play an important role in defining tree species distributions rich tropical forests. To what extent the same applies to relatively small, poor West African montane forests is unknown. Here, survive a grassland matrix and fire has played key their spatial temporal dynamics since Miocene. these influence local distributions, as compared with other environmental variables such altitude moisture remain we use data from 20.28 ha forest plot Ngel Nyaki Forest Reserve, South-East...
Abstract Plant phenology drives population dynamics and forest productivity; it is also impacted by shifting environmental cues under climate change such as more prevalent drought. It imperative to better understand how species community respond in leaf turnover reproduction, both of which are required integrate into full life‐cycle assessments. However, relatively few studies date examined the quantity timing simultaneously. We demonstrate that simultaneous assessment phenological across...
A uniquely high level of anoxia tolerance has been observed in Spitsbergen populations some common arctic vascular plant species. The most surprising aspect these species is their ability to maintain turgid, green leaves throughout the period and into postanoxic recovery phase. Prolonged never reported previously for leaves, which normally lose turgor wither rapidly when deprived oxygen. Tests on more southern from Norway, Iceland, Scotland found be tolerant failed detect an equivalent...
We provide evidence for the origin of sexual individuals from parthenogenetic progenitors in natural populations. demonstrate that this reversal has occurred independently three geographically separated populations Asteraceous polyploid, Hieracium pilosella. used chromosome counts and flow cytometry to determine ploidy crossing experiments confirm sexuality. Inter–simple sequence repeat allozyme markers demonstrated sexuals at each site were more closely related their neighbors than other...
