Deadwood is a large global carbon store with its size partially determined by biotic decay. Microbial wood decay rates are known to respond changing temperature and precipitation. Termites also important decomposers in the tropics but less well studied. An understanding of their climate sensitivities needed estimate change effects on pools. Using data from 133 sites spanning six continents, we found that termite discovery consumption were highly sensitive (with increasing >6.8 times per 10°C...
Background: In Kurram district of Pakistan, people use medicinal plants to cure a variety livestock diseases. This study was conducted with the aims document indigenous knowledge used in veterinary practices district.Methods: Ethnoveterinary data were collected through semi-structured interviews 97 participants that purposedly chosen at random locations and quantitatively analyzed using relative frequency citation (RFC) value (UV).Results: total 81 belonging 43 families recorded. Asteraceae...
Abstract Increased drought is forecasted for tropical regions, with severe implications the health and function of forest ecosystems. How mature trees will respond to water deficit poorly known. We investigated wood anatomy leaf traits in lowland after 24 months experimental rainfall exclusion. Sampling sun‐exposed young canopy branches from target species, we found species‐specific systematic variation hydraulic‐related response stress. Relative controls, drought‐affected individuals...
Abstract Although closed‐canopy forests are characterized by low‐light availability and slow population dynamics, many under threat from non‐native, invasive woody species that combine high colonization ability fast growth potential with survival. This ‘superinvader’ phenotype contravenes expected trade‐offs predicted successional niche theory, posing a challenge to both invasion forest succession theory. We propose parsimonious conceptual model based on the whole‐plant light compensation...
Abstract Tropical forest and savanna biomes are pivotal in the functioning of Earth system. Both biodiverse under increasing threat due to land clearing anthropogenic climate change, play important roles global carbon cycle, through maintenance a large pool tropical forests, exchange savannas extensive landscape fires. Reliable mapping is essential understand how current distribution these vegetation types controlled by fire. Using Google Maps satellite imagery, we manually classified 24 239...
Understanding how tropical rainforest trees may respond to the precipitation extremes predicted in future climate change scenarios is paramount for their conservation and management. Tree species clearly differ drought susceptibility, suggesting that variable water transport strategies exist. Using a multi-disciplinary approach, we examined hydraulic variability lowland north-eastern Australia. We studied eight tree representing broad plant functional groups (one palm seven eudicot...
Summary Understanding the anatomical basis of plant water transport in forest ecosystems is crucial for contextualizing community‐level adaptations to drought, especially life‐form‐rich tropical forests. To provide this context, we explored wood functional anatomy traits related hydraulic architecture across different groups a lowland rain forest. We measured 90 species from six (mature‐phase, understorey and pioneer trees; shrubs; vines) these intrinsic water‐use efficiency ( WUE i ) as...
Tropical rain forest expansion and savanna woody vegetation thickening appear to be a global trend, but there remains uncertainty about whether is common set of drivers. Using geographic information techniques, we analyzed aerial photography five areas in the humid tropics northeastern Queensland, Australia, taken 1950s 2008, determine if changes extent match those reported for Australian monsoon using similar techniques. Mapping showed that combined study area (64,430 ha), 63% was...
Although rain forest is characterized as pyrophobic, pyrophilic giant eucalypts grow emergents in both temperate and tropical Australia. In Australia, such depend on extensive, infrequent fires to produce conditions suitable for seedling growth. Little known, however, about constraints seedlings of eucalypts. We tested whether Eucalyptus grandis experience edaphic similar their counterparts. hypothesized that phosphorous addition would alleviate constraints. grew a factorial experiment...
SUMMARY Seasonally Dry Tropical Forests (SDTF) are gaining recognition as a significant biome and poorly conserved tropical biodiversity refuge. Understanding floristic relationships within SDTF is essential for their effective conservation. This study examines the variation of Caatinga Biogeographic Domain, in north-eastern Brazil. trees, shrubs arborescent cacti were sampled six localities Brazilian states Minas Gerais Bahia. A number soil chemical attributes also measured to analyse...
Background: Understanding patterns in traditional plant use knowledge is crucial for assisting policy making with regard to nature conservation, human nutrition, health, as well educational and participatory processes communities. We aim document describe local ethnobotanical test the hypothesis that gender structures of possessed by artisanal fishers a fishing community northeast Bahia, Brazil.Methods: Through semi-structured interviews guided walks experts, we recorded medicine, food, wood...
Ecological theory differentiates rainforest and open vegetation in many regions as functionally divergent alternative stable states with transitional (ecotonal) between the two forming transient unstable states. This is of considerable significance, not only a test case for theories dynamics, but also because this type major economic importance, home to suite species conservation including world's tallest flowering plants. We therefore created predictions patterns plant functional traits...
Abstract Climate change scenarios predict increasing atmospheric CO2 concentrations ([CO2]), temperatures and droughts in tropical regions. Individually, the effects of these climate factors on plants are well established, whereas experiments interactive a combination rare. Moreover, how environmental will affect tree species along wet to dry gradient (e.g., forest–savanna transitions) remains be investigated. We hypothesized that under simulated conditions, plant growth, physiological...
Litsea Lam. is an ecological and economic important genus of the “core Lauraceae” group in Lauraceae. The few studies to date on comparative chloroplast genomics phylogenomics have been conducted as part other Here, we sequenced whole genome sequence auriculata, endangered tree endemic eastern China, compared this with previously published sequences 11 species. genomes 12 species ranged from 152,132 (L. szemaois) 154,011 bp garrettii) exhibited a typical quadripartite structure conserved...
Abstract Strawberry guava ( P sidium cattleianum ) is a shade‐tolerant shrub or small tree invader in tropical and subtropical regions considered among the world's top 100 worst invasive species. Studies from affected report deleterious effects of strawberry invasion on native vegetation. Here we examine life history demographics environmental determinants invasions to inform effective weed management rainforest regions. We surveyed vegetation 8 mature 33 successional sites at various stages...
Full floristic data, tree demography, and biomass estimates incorporating non-tree lifeforms are seldom collected reported for forest plots in the tropics. Established research stations serve as important repositories of such biodiversity ecological data. With a canopy crane setup within tropical lowland rainforest estate, 42-ha Daintree Rainforest Observatory (DRO) Cape Tribulation, northern Australia is facility international significance. We obtained an estimate vascular plant species...
Understanding succession in tropical forest is an important aspect of vegetation science, but to date, successional processes seasonally dry forests (SDTFs) have received much less attention than evergreen humid forests. We aim fill this knowledge gap. investigated SDTF areas consisting three different stages (early, intermediate, late), and a SDTF-savanna ecotone the municipal district Juramento, north Minas Gerais State, Brazil. Using twelve 400 m2 plots each area, we compared parameters...
Bryophyte communities are highly sensitive to moisture and/or humidity levels. Most studies on the subject focus bryophytes either tree or ground habitats and do not consider how partition themselves across both epiphytic substrates within same forest. Sampling mesic temperate forest sites of physiognomy from two Tasmanian regions with slightly different levels (a wetter northwest versus a drier northeast region), we examine various aspects community structure (overall liverwort moss cover;...
