Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change. Location Tropical and subtropical moist forests. Time period Current. Major taxa studied Palms (Arecaceae). Methods We assembled a pantropical dataset of 2,548 forest plots (covering 1,191ha) and quantified tree palm (i.e., ≥10cm diameter at breast height) abundance relative to co‐occurring non‐palm trees. We compared the relative abundance of tree palms across biogeographical realms and tested for associations with palaeoclimate stability, current climate, edaphic conditions and metrics of forest structure. Results On average, the relative abundance of tree palms was more than five times larger between Neotropical locations and other biogeographical realms. Tree palms were absent in most locations outside the Neotropics but present in >80% of Neotropical locations. The relative abundance of tree palms was more strongly associated with local conditions (e.g., higher mean annual precipitation, lower soil fertility, shallower water table and lower plot mean wood density) than metrics of long‐term climate stability. Life‐form diversity also influenced the patterns; palm assemblages outside the Neotropics comprise many non‐tree (e.g., climbing) palms. Finally, we show that tree palms can influence estimates of above‐ground biomass, but the magnitude and direction of the effect require additional work. Conclusions Tree palms are not only quintessentially tropical, but they are also overwhelmingly Neotropical. Future work to understand the contributions of tree palms to biomass estimates and carbon cycling will be particularly crucial in Neotropical forests.

Higher levels of taxonomic and evolutionary diversity are expected to maximize ecosystem function, yet their relative importance in driving variation in ecosystem function at large scales in diverse forests is unknown. Using 90 inventory plots across intact, lowland, terra firme, Amazonian forests and a new phylogeny including 526 angiosperm genera, we investigated the association between taxonomic and evolutionary metrics of diversity and two key measures of ecosystem function: aboveground wood productivity and biomass storage. While taxonomic and phylogenetic diversity were not important predictors of variation in biomass, both emerged as independent predictors of wood productivity. Amazon forests that contain greater evolutionary diversity and a higher proportion of rare species have higher productivity. While climatic and edaphic variables are together the strongest predictors of productivity, our results show that the evolutionary diversity of tree species in diverse forest stands also influences productivity. As our models accounted for wood density and tree size, they also suggest that additional, unstudied, evolutionarily correlated traits have significant effects on ecosystem function in tropical forests. Overall, our pan-Amazonian analysis shows that greater phylogenetic diversity translates into higher levels of ecosystem function: tropical forest communities with more distantly related taxa have greater wood productivity.

Metallo-β-lactamases provide bacteria with an efficient and effective way of mediating resistance to β-lactam-based antibacterial agents. More significantly, they confer resistance to carbapenems. Therefore, if metallo-β-lactamases increase in prevalence, they could compromise the efficacy of this group of antibiotics to treat life-threatening hospital infections. Metallo-β-lactamases have now been identified in a wide spectrum of clinically important pathogens, such as Klebsiella pneumoniae, Pseudomonas aeruginosa, Serratia marcescens, and Acinetobacter sp. (21; H. Ito, K. Senda, T. Yagi, K. Shibayama, M. Ohta, N. Kato, and Y. Arakawa, Abstr. 37th Intersci. Conf. Antimicrob. Agents Chemother., abstr. C-93, 1997). These enzymes also possess a proven capability to disseminate through bacterial populations, which is demonstrated by the spread of the IMP-1 metallo-β-lactamase in Japan (reviewed in reference 17). The spread of this enzyme is thought to be facilitated by its being encoded on an integron (1). More recently, clinical isolates producing metallo-β-lactamases have been identified in Europe (5, 12, 24). One approach to combating this potential clinical problem is the use of a specific metallo-β-lactamase inhibitor in combination with a β-lactam antibiotic. In this regard a range of different non-β-lactam based molecules have been identified as specific inhibitors of these enzymes. A series of mercaptoacetic acid thiol ester compounds were identified as mechanism-based, irreversible inhibitors of metallo-β-lactamases (18). Walter et al. (23) described a series of trifluoromethyl alcohol and ketone inhibitors that were competitive inhibitors of a range of metallo-β-lactamases, and a group of biphenyl tetrazole compounds have been shown to be specific inhibitors of the Bacteroides fragilis CfiA-type metallo-β-lactamase (22). None of these compounds exhibited significant synergy with β-lactam antibiotics, nor did they exhibit potent broad-spectrum inhibition of metallo-β-lactamases. However, a recently discovered series of mercaptocarboxylates have been shown to exhibit both broad-spectrum metallo-β-lactamase inhibitory activity and antibacterial synergy with meropenem (17). In our quest to identify novel inhibitors of metallo-β-lactamases, we screened natural product extracts against the Bacillus cereus II enzyme and identified an extract from a strain of Chaetomium funicola with inhibitory activity against metallo-β-lactamases. SB236050, SB238569, and SB236049 were successfully extracted and purified from this extract, and we now report on the purification, extraction, and characterization of this novel series of metallo-β-lactamase inhibitors derived from a natural product.

Two novel metabolites, SB 212021 and SB 212305, have been isolated from a Streptomyces and shown to have molecular formulae of C15H10N2O5 and C20H17N3O8S, respectively. The structures were deduced by a combination of NMR techniques and mass spectral fragmentation patterns and shown to be novel members of the phenazine group of antibiotics. In the absence of added zinc, both compounds had IC50's of 1-75 microM for the Bacteroides fragilis 262 CfiA and Xanthomonas maltophilia L-1 metallo-beta-lactamases. The compounds also inhibited ACE with IC50's of 55 and 68 microM, respectively. Mode of action studies illustrate that the compounds inhibit some metalloenzymes by chelation of the active site metal ion. They exhibit poor antibacterial activity.

Two novel isoleucyl tRNA synthetase inhibitors, SB-203207 and SB-203208 have been isolated from a Streptomyces sp. and found to be structurally related to altemicidin. Structures of SB-203207 and SB-203208 have been deduced by a combination of spectroscopic techniques, derivatisation, hydrolysis studies and found to be 4-(aminocarbonyl)-7-[[(2-amino-3-methylpentanoyl)aminosul phonyl]acetamido]-2,4a,5,6,7,7a-hexahydro-6-hydroxy-2-methyl-1H-2- pyrindine-7-carboxylic acid (1) and 4-(aminocarbonyl)-7-[[(2-amino-3-methyl pentanoyl)-aminosulphonyl]acetamido]-2,4a,5,6,7,7a-hexahydro-6-(2- amino-3-phenylbutanoyl oxy)-2-methyl-1H-2-pyrindine-7-carboxylic acid (2), respectively.
