“…Due to the implementation of effective biological control, the weedy status of C. odorata has arguably declined in many areas (particularly more humid, tropical regions) (Muniappan et al, 2005; Uyi et al, 2014). In some cases such as in an Indo Burma hotspot region, this decline may have been mediated through invasion of more aggressive weeds such as Tithonia diversifolia (Rai et al, 2023; Vanlalruati & Rai, 2021). Nevertheless, these studies are important to initiate the economic quantification of its control measures.…”

“…Coupling of plant invasion management with bioeconomy (refers to economy based on renewable bioresources or biorefinery) can contribute to environmental sustainability, addressing bioinsecurity, socio-economy/livelihood, climate action (by minimizing carbon emissions and reliance on traditional fossil fuels), food security, SDGs, and "Plant-Energy" nexus (Rai et al, 2023). The advantage of using plant invaders as feedstock for biorefinery lies in the fact that they do not use fertile agriculture lands allocated for raising food crops and rather possess the potential to be climate resilient, saline/ drought tolerant with ability to grow in impoverished ecosystems such as disturbed or marginal wastelands.…”

“…The indigenous global biodiversity is vital for environmental pollution amelioration and sustainability (Pyšek et al, 2020; Swaminathan, 2003). However, the global trade and anthropogenic disturbance driven upsurge in the diversity of invasive alien plants in novel habitats have significantly transmogrified the global phytosociology through biotic homogenization which potentially threatened the native biodiversity in forestry, agroforestry, and agriculture systems (Hulme, 2021; Rai et al, 2023; Richardson et al, 2000; Zavaleta et al, 2003). Thus, the landscape spread of plant invaders emerged as serious challenge to the biodiversity conservation, ecosystem restoration, and nature sustainability (Hulme, 2012; Richardson et al, 2007; Sala et al, 2000).…”

The Anthropocene witnessed the landscape spread of several invasive alien plants which can remarkably influence the ecosystem services and environmental sustainability. To this end, Chromolaena odorata (Asteraceae) is widely identified among top hundred pervasive invaders in view of its adverse influence on environment, agriculture, and wildlife. The adverse effects of C. odorata can further be exacerbated under the event of invasion interaction with other anthropogenic stressors such as climate change. Nevertheless, there exists dearth of pragmatic studies on invasion ecology, socio‐economic impacts, ecological economics, and sustainable management prospects of C. odorata. The present review discusses the invasion ecology, distribution, mechanisms, impacts, and management strategies of C. odorata invasion. The side‐effects and unsustainable use of traditional control measures (e.g., controlled fire and chemical herbicides) of C. odorata paves the way to biological control methods (e.g., gall fly). However, the control measures of C. odorata need to be assessed for their long‐term ecosystem level effects to mitigate the possible adverse environmental responses. The wise application of C. odorata biomass in marginal lands for soil fertility restoration, biosorption, biorefinery, bio‐medicine, and bioenergy in conjunction with ecological control measures can cover economic incentive to facilitate sustainable management of C. odorata in forestry/agroforestry systems. Nevertheless, the use of weed biomass as feedstock in biorefinery and ethno‐medicine may be inadequate in reducing its invasion. Future studies should explicitly elucidate the ecological mechanisms of C. odorata in concert with the quest for its field‐scale application in biorefinery to augment sustainable management.

Tithonia diversifolia (Hemsl.) A. Gray has significant potential as a forage source in silvopastoral systems, particularly in tropical conditions. However, its intensity and frequency management differ from those commonly applied to grasses. This study aims to evaluate T. diversifolia under two harvest intensities (30 and 40 cm stubble height) and four harvest frequencies (21, 28, 35, and 42 days), aligning with Brazil’s traditional tropical grass management practices. Biomass production and nutritive value of forage, as well as in vitro rumen fermentation parameters were assessed. We observed that the tested harvest intensities have a limited impact on the biomass production and nutritional value of T. diversifolia. Despite the linear increase in biomass production, lower harvest frequencies (i.e., longer regrowth period) significantly affects nutritional value, impacting the products of ruminal fermentation, as indicated by the in vitro assay. The methane production per gram of degraded organic matter (OM) and the OM allocated for microbial biomass production are affected by the harvest frequencies. Additionally, we observed that rainfall and canopy height have stronger correlation with biomass production than harvest frequencies controlled by days. We conclude that T. diversifolia is minimally affected by harvest intensities and, for Brazilian edaphoclimatic conditions, it can be harvested with higher frequencies than those suggested for other regions.

“…We are particularly interested in terrestrial invasive plant species (TIPS) because many of them produce large amounts of seeds, which are easily distributed by the wind, birds, other animals, and unknowing humans (USDA, 2024b). TIPS thrive in natural and disturbed areas and outcompete native plant species (Rai et al, 2023). Some TIPS have a very aggressive root system capable of spreading a long distance and smothering the root systems of neighboring plants (Lawson et al, 2021;Rai et al, 2023).…”

DNA barcoding of terrestrial invasive plant species in Southwest Michigan

Because of the detrimental effects of terrestrial invasive plant species (TIPS) on native species, ecosystems, public health, and the economy, many countries have been actively looking for strategies to prevent the introduction and minimize the spread of TIPS. Fast and accurate detection of TIPS is essential to achieving these goals. Conventionally, invasive species monitoring has relied on morphological attributes. Recently, DNA‐based species identification (i.e., DNA barcoding) has become more attractive. To investigate whether DNA barcoding can aid in the detection and management of TIPS, we visited multiple nature areas in Southwest Michigan and collected a small piece of leaf tissue from 91 representative terrestrial plant species, most of which are invasive. We extracted DNA from the leaf samples, amplified four genomic loci (ITS, rbcL, matK, and trnH‐psbA) with PCR, and then purified and sequenced the PCR products. After careful examination of the sequencing data, we were able to identify reliable DNA barcode regions for most species and had an average PCR‐and‐sequencing success rate of 87.9%. We found that the species discrimination rate of a DNA barcode region is inversely related to the ease of PCR amplification and sequencing. Compared with rbcL and matK, ITS and trnH‐psbA have better species discrimination rates (80.6% and 63.2%, respectively). When ITS and trnH‐psbA are simultaneously used, the species discrimination rate increases to 97.1%. The high species/genus/family discrimination rates of DNA barcoding indicate that DNA barcoding can be successfully employed in TIPS identification. Further increases in the number of DNA barcode regions show little or no additional increases in the species discrimination rate, suggesting that dual‐barcode approaches (e.g., ITS + trnH‐psbA) might be the efficient and cost‐effective method in DNA‐based TIPS identification. Close inspection of nucleotide sequences at the four DNA barcode regions among related species demonstrates that DNA barcoding is especially useful in identifying TIPS that are morphologically similar to other species.
