“…Therefore, for a certain capacity of resource transportation, P. longiflora allocated more resources to flower at SE slope while at the SW slope aspect allocated more resource to leaf to ensure individual plants growth and development. An ecological trade-off between different organs was detected in relation to slope exposure, which had been observed in survivorship and fecundity in relation to seedling emergence time of Anthemis cotula in the Kashmir valley (Allaie et al, 2006). Furthermore, there were no significant differences in plant height and leaf number between the two slope aspects.…”

“…Moreover, biomass allocation pattern plays an essential role in the life history of plants (Reekie and Bazzaz, 2005), because biomass is not only associated with morphological, growth and reproductive traits (Allaie et al, 2006), but also associated with metabolism, CO 2 assimilation, and carbon sequestration. Plant height plays a crucial role of ecological variation in the species for survival, competitive ability and reproduction (Cornelissen et al, 2003), and it is related to many important functional traits (Westoby 1998;Westoby et al, 2002;Poorter et al, 2003).…”

“…Allocation of above ground biomass (AGB) and below ground biomass (BGB) has been extensively discussed for root to shoot (R/S) ratio, which plays an important role in carbon cycle models (Allaie et al, 2006;Enquist and Niklas, 2002;Wu et al, 2013). For certain species, given that the plant biomass allocation is largely genetically regulated, environmental factors can still flexibly shift investments towards the needed structures, whose allocation patterns of plastic resource are also in response to varying growing conditions (Allaie et al, 2006;Patty et al, 2010).…”

Abstract. Pedicularis longiflora is a typical grassland plant located in the alpine habitat in wet meadows or besides streams. This paper addresses the response and adaptation of P. longiflora under heterogeneous environmental conditions at different slope aspects in an alpine wet meadow, eastern Tibetan Plateau. The results show that P. longiflora at the southeast slope benefited more for its development and population maintenance. It also showed a relatively greater leaf biomass. However, P. longiflora invested more biomass to reproductive organs at the southwest slope aspect, where this species has better population continuation. Isometric scaling existed in coupled organ biomasses of P. longiflora which indicated that genetic regulation plays a key role in biomass allocation. P. longiflora allocated more biomass to aboveground parts, vegetative biomass, and non-photosynthetic organs biomass according to tradeoff values, respectively. In addition, both biotic and abiotic factors influenced biomass production of P. longiflora. Thus, soil temperature and interspecies competition in different habitats needs to be clearly understood and paid more attention to for cultivation and better industrialization of this herbal medicinal plant.

“…Most A. cotula germination occurs in fall or spring at the same time as the fall‐ and spring‐seeded crops that it infests (Kay, 1971a; Allaie et al , 2005), but facultative germination can also occur throughout the growing season when soil moisture is sufficient (Ilnicki and Johnson, 1959). Fall‐germinated plants typically reach a frost‐hardy rosette stage before winter and restart their growth in the spring and early summer (Fertig and Furrer, 1963; Kay, 1971a).…”

Mayweed chamomile (Anthemis cotula L.) biology and management—A review of an emerging global invader

2020

The globally invasive weed, mayweed chamomile (Anthemis cotula L.) is an annual, bushy, ill‐scented herb, originating in Eurasia. It is aggressively weedy in croplands, field‐side ditches, wet areas and along roadsides, especially in slightly acidic, nitrogen‐rich, clay‐loam soils. In addition to interfering with crop growth, the weed causes dermatitis and eye irritation in humans, skin rashes and sour mouth in domesticated mammals, and off‐flavours in cow's milk through forage contamination. Although A. cotula may be managed effectively with some broadleaf herbicides in cereal crops, it is much more difficult to manage in broadleaved crops and cover crops. In some regions, aggressive use of relatively few herbicides has selected for acetolactate synthase herbicide resistance in A. cotula. Therefore, A. cotula poses serious ecological and economic challenges in many regions. Despite this threat, the details of A. cotula biology and ecology in the context of environmental change remain relatively unknown. For example, the reason for the invasiveness of A. cotula remains uncertain, but is presumed to be due to abundant seed production, allelochemicals, mycorrhizal associations, minimal herbivory in invaded ranges, ability to attract generalist pollinators through an extended flowering period and adaptive capacity in a wide range of soil types and conditions. In this paper, we comprehensively review the literature and ongoing work on A. cotula and provide a research agenda to improve understanding and management of this species.

Phylogenetic relatedness of plant species co‐occurring with an invasive alien plant species varies with elevation

Darwin's naturalization conundrum posits that the alien species either succeed in the introduced region because they are phylogenetically related to the native species and thus tend to have niches similar to those of native species, or they are phylogenetically dissimilar to native species and thus occupy unfilled niches. This conundrum has received a lot of attention, but the findings regarding these two hypotheses have been contradictory. To reconcile the two seemingly contradictory hypotheses, we assessed the phylogenetic relationship of a highly widespread and invasive species, Anthemis cotula L. (focal species), separately with the native species and all its co‐occurring species (including native and non‐native species) along an elevation gradient. Our results show that the abundance of A. cotula declined continuously with an increase in elevation and with an increase in the number of both all co‐occurring and native species only. The phylogenetic distance between the focal species and the native species based on weighted mean pairwise distance (MPDaw) declined with elevation as well as native species richness. Our study also revealed that soil nutrients strongly influence the abundance of A. cotula; however, their effect on the phylogenetic distance between the focal and other species is negligible. These findings suggest a strong role of microecological factors and spatial heterogeneity in the abundance distributions of invasive species and community assembly. Thus, it could be concluded that the phylogenetic relationship of A. cotula with co‐occurring all or only native species varies with elevation and species richness, adding another layer of complexity to the resolution of Darwin's naturalization conundrum.
