Diverse root strategies associated with fast to slow resource acquisition vary among plant growth forms
<p>Root acquisition strategies at regional and global scales are largely associated with climate, soil resource availability, and plant phylogeny, yet the drivers at the local scale are not well-quantified. We sampled 115 species across five growth forms (i.e. trees, shrubs, lianas, herbs, and ferns) from a temperate forest and measured seven key functional traits of first-order roots, including root morphology, anatomy, and chemistry. Most trait variations were greater among growth forms than within them. Importantly, species aggregated in root economics space separately by growth forms, illustrating consistent differences in soil resource strategies among growth forms from fast to slow acquisition. Such diverse strategies among plant growth forms may allow species to avoid strong competition and promote species coexistence in a local forest community. These findings improve our understanding of the mechanisms underlying community assembly and stability from a below-ground perspective.</p>

Data from: Effects of variation in resource acquisition during different stages of the life cycle on life-history traits and trade-offs in a burying beetle
Individual variation in resource acquisition should have consequences for life-history traits and trade-offs between them because such variation determines how many resources can be allocated to different life-history functions, such as growth, survival and reproduction. Since resource acquisition can vary across an individual's life cycle, the consequences for life-history traits and trade-offs may depend on when during the life cycle resources are limited. We tested for differential and/or interactive effects of variation in resource acquisition in the burying beetle Nicrophorus vespilloides. We designed an experiment in which individuals acquired high or low amounts of resources across three stages of the life cycle: larval development, prior to breeding and the onset of breeding in a fully crossed design. Resource acquisition during larval development and prior to breeding affected egg size and offspring survival, respectively. Meanwhile, resource acquisition at the onset of breeding affected size and number of both eggs and offspring. In addition, there were interactive effects between resource acquisition at different stages on egg size and offspring survival. However, only when females acquired few resources at the onset of breeding was there evidence for a trade-off between offspring size and number. Our results demonstrate that individual variation in resource acquisition during different stages of the life cycle has important consequences for life-history traits but limited effects on trade-offs. This suggests that, in species that acquire a fixed-sized resource at the onset of breeding, the size of this resource has larger effects on life-history trade-offs than resources acquired at earlier stages.
Data from: Immune response costs are associated with changes in resource acquisition and not resource reallocation
1. Evolutionary ecologists frequently argue that parasite defence is costly because resources must be reallocated from other life-history traits to fuel the immune response. However, this hypothesis is rarely explicitly tested. An alternative possibility is that immune responses impair an organism's ability to acquire the resources it needs to support metabolism. Here, we disentangle these opposing hypotheses for why the activation costs of parasite resistance arise. 2. We studied fecundity costs associated with immune stimulation in Drosophila melanogaster. Then, by measuring correlated changes in metabolic rate, food consumption and body weight, we assessed whether responses were consistent with immunity costs originating from altered resource allocation or from impaired resource acquisition. 3. Microbial injection resulted in a 45% fecundity decrease. It also triggered a mean decline in metabolic rate of 6% and a mean reduction in food intake of 31%; body weight was unaffected. Metabolic rate downregulation was greater in males than in females, whereas declines in food ingestion were of similar magnitude in both sexes. These physiological shifts did not depend on whether microbial challenges were alive or dead, thus they resulted from immune system activation not pathogenesis. 4. These costs of immune activation are significant for individuals that successfully resist infection and might also occur in other situations when immune responses are upregulated without infection. 5. Whilst we found significant activation costs of resistance, our data provide no compelling evidence for the popularly argued hypothesis that immune deployment is costly because of reallocation of energetic resources to the immune system. Instead, reduction in resource acquisition due to 'infection-induced anorexia' may be the principal driver of metabolic changes and fecundity costs resulting from immune response activation.
Alpine plant species converge towards adopting elevation-specific resource-acquisition strategy in response to experimental early snow-melting
<p>An experimental to assess the effect of early snow-melting on alpine species at contrasting elevation was established in 2019 at Rohtang (32°22' N; 77°16' E) in western Himalaya. After completion of 02 year of experiment, sampling was performed on 08 alpine plant species. We have collected leaf functional trait and physiological traits during peak growing season (August 2020) from two elevation (3850 and 4150 m) and from control and treatment plots. The trait values of 15 replicates for each species were given here for leaf functional traits (viz. leaf area, specific leaf area, leaf dry matter content, leaf water content, plant height) and trait values of 05 replicated for each species were given for elemental (Nitrogen % and carbon/nitrogen ratio ) and physiological traits (leaf chlorophyll content, Carotenoid content, Malondialdehyde equivalents, Phenol content, Proline content, Total soluble Sugar content, Total protein content). We have provided trait values from both control and treatment plots. </p>
