“…B 372: 20160142 degree of invasion generally reduced in more diverse communities. Similarly, Sheppard et al [126] reported high variability in whether drought or heavy rainfall facilitated exotic performance. Establishment success of native versus exotic seedlings has also been demonstrated to depend on whether a temperature extreme was positive or negative [127], suggesting that there will be important interactions between the type of climate extreme and the traits of the invaders.…”

Climate extremes will elicit responses from the individual to the ecosystem level. However, only recently have ecologists begun to synthetically assess responses to climate extremes across multiple levels of ecological organization. We review the literature to examine how plant responses vary and interact across levels of organization, focusing on how individual, population and community responses may inform ecosystem-level responses in herbaceous and forest plant communities. We report a high degree of variability at the individual level, and a consequential inconsistency in the translation of individual or population responses to directional changes in community- or ecosystem-level processes. The scaling of individual or population responses to community or ecosystem responses is often predicated upon the functional identity of the species in the community, in particular, the dominant species. Furthermore, the reported stability in plant community composition and functioning with respect to extremes is often driven by processes that operate at the community level, such as species niche partitioning and compensatory responses during or after the event. Future research efforts would benefit from assessing ecological responses across multiple levels of organization, as this will provide both a holistic and mechanistic understanding of ecosystem responses to increasing climatic variability. This article is part of the themed issue ‘Behavioural, ecological and evolutionary responses to extreme climatic events’.

“…With an eye to the potential impacts of climate change, ecological research has increasingly focused on climatic variability (Wang & Dillon, ; Vázquez et al ., ; Boyd et al ., ) and extreme events (Jentsch et al ., ; Smith, ; Knapp et al ., ; Bailey & van de Pol, ). Studies have demonstrated the implications of climatic variance and extremes for behavior (Rubenstein, ; Papaj et al ., ; Frick et al ., ), demography (Sæther, ; Langin et al ., ; Jónsson et al ., ), distributions (Reside et al ., ; Bateman et al ., ), community composition (Albright et al ., ; Hoover et al ., ), mass mortality events (McKechnie & Wolf, ; Anderegg et al ., ), fire dynamics (Westerling et al ., ; Littell et al ., ; Abatzoglou & Kolden, ), carbon cycling (Frank et al ., ), and invasive species (Vilà et al ., ; Diez et al ., ; Sheppard et al ., ), among others. The temporal scale at which extreme events are defined varies from daily to multidecadal timescales, with the timescale of interest dependent on the impact of interest (e.g., heat‐induced mortality versus annual gross primary productivity).…”

Identifying the climatic drivers of an ecological system is a key step in assessing its vulnerability to climate change. The climatic dimensions to which a species or system is most sensitive - such as means or extremes - can guide methodological decisions for projections of ecological impacts and vulnerabilities. However, scientific workflows for combining climate projections with ecological models have received little explicit attention. We review Global Climate Model (GCM) performance along different dimensions of change and compare frameworks for integrating GCM output into ecological models. In systems sensitive to climatological means, it is straightforward to base ecological impact assessments on mean projected changes from several GCMs. Ecological systems sensitive to climatic extremes may benefit from what we term the 'model space' approach: a comparison of ecological projections based on simulated climate from historical and future time periods. This approach leverages the experimental framework used in climate modeling, in which historical climate simulations serve as controls for future projections. Moreover, it can capture projected changes in the intensity and frequency of climatic extremes, rather than assuming that future means will determine future extremes. Given the recent emphasis on the ecological impacts of climatic extremes, the strategies we describe will be applicable across species and systems. We also highlight practical considerations for the selection of climate models and data products, emphasizing that the spatial resolution of the climate change signal is generally coarser than the grid cell size of downscaled climate model output. Our review illustrates how an understanding of how climate model outputs are derived and downscaled can improve the selection and application of climatic data used in ecological modeling.

“…In general for the success and impact of any weed many biotic and abiotic environmental factors are responsible (Sheppard et al, 2012). One of the most important factor for the huge prevalence of this weed throughout world is its phytotoxic or allelopathic action which is due to the presence of phenolic compounds (umbelliferone, methylcoumarin, salicylic acid etc.)…”

KEYWORDS Lantana camara Lantadenes Allelopathy Hepatotoxic Poisonous ABSTRACTLantana camara is one of the most commonly known noxious weed distributed worldwide. The red flower variety (L. camara var. aculeata) of this weed is mainly toxic and usually prevalent in tropical and sub-tropical countries. Lantana leads to hepatotoxicity, photosensitization and intrahepatic cholestasis almost in all the animals. LA is the main toxic pentacyclic triterpenoid present in this weed. Lantadene toxicity leads to fatty degeneration, bile duct hyperplasia, gall bladder edema, degeneration of parenchymal cells and portal fibrosis observed on histopathological examination. L. camara toxicity causes fluctuation in hematological as well as in biochemical parameters. The management of toxic effects can be achieved by activated charcoal, vaccination and supportive therapy but are not much effective. Besides the harmful effects of this plant, there are some beneficial effects also including antiinflammatory, hepatoprotective action, antitumor action etc. The control of this weed is difficult because of its allelopathic action. Nowadays this plant is used in many recent advanced techniques like phytoremediation of particulate pollution, phytoextraction of heavy metals and many others. Thereby the use of this plant in the field of research can be an effective way to manage this alien weed. As far as the toxicity is concerned it can be prevented by the using conventional therapeutic methods along with immunological, nanotechnological and biotechnological approaches. The aim of this article is to discuss the information regarding its progression, mechanism by which it affect animals, pathological alterations, treatment and what strategies we can opt to get rid of this weed.
