2015/16 El Niño increased water demand and pushed plants from a Mesic tropical montane grassland beyond their hydraulic safety limits
<p>In 2015/16, a strong El Niño event caused anomalously high temperatures and reduced precipitation resulting in Pantropical drought‐induced diebacks and wildfires. Although many studies have documented the El Niño impacts on tropical forests, little we know about its effects on tropical grasslands. Here, we investigated plant drought responses during and after the 2015/16 El Niño event (Jun 2016 to Aug 2017) in 12 species with contrasting drought strategies (tolerance, avoidance and escape) in a Brazilian tropical montane grassland. We tested if (1) the El Niño event induced meteorological drought anomalies, (2) the atmospheric and/or soil drought led to plant water stress and (3) plants showed signs of drought recovery. In contrast to other tropical areas, we found that the 2015/16 El Niño event did not strongly affect precipitation in our study site. However, it increased air temperature and vapour pressure deficit, thus pushing all grassland species, even the most drought‐tolerant ones, beyond their hydraulic safety margins during the dry season. Most species showed signs of drought recovery, returning to positive hydraulic margins in the wet season after the El Niño. However, the finding that all evaluated species, regardless of their drought‐response strategy, are already operating close to their hydraulic safe thresholds for stomatal closure and turgor loss suggests that this cool–humid tropical montane grassland is especially vulnerable to meteorological extremes exacerbated by the additive effects of El Niño and climate change.</p>
Tropical plant–hummingbird interactions withstand short-term experimental removal of a common flowering plant
<p>In this study, we simulated the extirpation of a hummingbird-pollinated understory plant, <em>Heliconia tortuosa</em>, from tropical forest fragments using a replicated Before-After-Control-Impact (BACI) experimental design while quantifying hummingbird space use, foral visitation rates, and plant pollination success. Each response variable was measured during each experimental period (pre and post) in sites with and without <em>H. tortuosa </em>removal (treatment and control).</p>

Eighteen-year nitrogen addition does not increase plant phosphorus demand in a nitrogen-saturated tropical forest
<ol> <li><span>Nitrogen (N) deposition usually increases plant tissue N concentrations and thus phosphorus (P) demand in young and/or N-limited forests, but the N-deposition effect on plant P demand has rarely been assessed in N-saturated forests.</span></li> <li><span>Impacts of 18-year external N additions (Control: 0, Low N: 50, Moderate N:100, and High N: 150 kg N ha<sup>-1</sup> yr<sup>-1</sup>) on leaf P of four plant life-forms (tree, shrub, herb, and liana), P fractions of bulk and rhizosphere soils were examined in a N-saturated mature tropical forest in southern China. </span></li> <li><span>Leaf N, P, and N: P ratios of all plant life-forms remained stable under three N-additions. Among soil P fractions, moderate labile organic P increased by 25-33% across three N-additions; and soil total P was increased by 11.76 % under Low N, and 8.87% under High N, compared with the control. The PLS-PM results showed that the path coefficient of microbial community to available P significantly increased and of inorganic P to available P significantly decreased under N additions than control. N additions improved soil P availability through microbe-mediated P transformation: Low N significantly increased soil microbial taxonomic diversity, and a higher microbial diversity could enlarge the sources of nutrient acquisition and stimulate decomposition of recalcitrant organic matters; while High N significantly decreased soil microbial taxonomic diversity, the remaining microorganisms that were screened by N-rich environments had the characteristics of resisting the N-addition effects and maintained efficient P acquisition.</span></li> <li> <span><em>Synthesis</em>.</span><span> Our findings provide a novel line of evidence that long-term N deposition did not increase plant P demand in a N-saturated mature tropical forest. The underlying mechanism is that plants did not increase N uptakes therefore nor increase P uptakes (a stable leaf N: P stoichiometry) in an already N-saturated ecosystem. Different N addition rates regulated soil P transformation via microbial community transition. These findings help improve the understanding of plant P acquisition and modeling of biogeochemical N-P cycling and vegetation productivity in N-rich forest ecosystems, particularly considering the fact that chronic N deposition may likely lead to soil N richness and even saturation of many forests in the future.</span> </li> </ol>

Data from: Decoding the drivers of deep-time wetland biodiversity: insights from an early Permian tropical lake ecosystem
<p><span>Wetlands are important to continental evolution, providing both the arenas and refugia for emerging and declining biotas, respectively. </span><span>Based on this significance and the high preservation potential, the resulting fossiliferous deposits play a key role in understanding past and future biodiversity. We reconstruct the trophic structure and age of the early Permian Manebach-Lake ecosystem, Germany, thriving in a wetland when the tropical biosphere faced profound upheaval in the peaking Late Palaeozoic Icehouse. Nine excavations, the high-resolution, spatiotemporal documentation of fossils and sediments, and the U-Pb radioisotopic dating of tuffs allow us to distinguish autogenic and allogenic factors that shaped the limnic biocoenosis. The Manebach Lake was an exorheic, stratified, perennial water body in the 10<sup>1</sup>–10<sup>2</sup> km<sup>2</sup> scale, integrated into the catchment draining much of the European Variscides. Lake formation paralleled an Asselian regional wet climatic interval and benefited from rising groundwater tables due to post-Variscan tectonics. Stromatolite-forming cyanobacteria, bivalves, several crustacean groups, amblypterids resembling <em>Paramblypterus duvernoyi</em> and xenacanthid sharks formed a differentiated biocoenosis. Digestive remains prove the rare presence of acanthodians, branchiosaurs, and large tetrapods. Anoxic events affected the mainly epilimnal community. The results indicate woody-debris-bearing lake littorals devoid of semi-aquatic and aquatic plants as places suitable for large stromatolites to grow, underpin the model of declining freshwater shark diversity in most Permian Variscan basins, demonstrate fish/amphibian ratios in limnic taphocoenoses to measure lake perenniality and reveal taphonomic biases in freshwater plant assemblages. Our outcomes highlight the need for more knowledge about the diversity, ecology, and fossilisation pathways of past limnic biotas, particularly microorganisms and actinopterygian fishes, to reconstruct deep-time continental ecosystems. </span></p>
