“…In the current study, analyses of the diversity indices between the invaded and control plots showed noticeable changes in the diversity of the plants. These findings are in line with those of Riaz and Javaid (2011), Shabbir and Bajwa (2007), Ojija et al (2021) and Ojija & Lutambi (2022) all of which report changes in the vegetation composition of the invaded plots. Crop output, biodiversity, and human and animal health are all impacted by parthenium (Shabbir, 2013).…”

The threat of invasion is growing globally and endangers biodiversity. Exotic invasive plants are putting a harm to the vegetation of Pakistan’s Pothwar region, which is a biodiversity hotspot. In the current study, the effects of Broussonetia papyrifera, Parthenium hysterophorus, Xanthium strumarium, and Lantana camara on the local flora in the Pothwar area were examined. Two categorical groups (invaded and non-invaded) were used in a dichotomized experimental design to collect data. Using the software PRIMER-7 and IBM SPSS v. 21, different diversity indices including Margalef’s index of species richness, Shannon index of diversity, and Simpson index of dominance were measured and compared between invaded and control plots. In comparison to the experimental plots, the control plots had an average of more individuals and diversity. On a multivariate scale, non-metric multidimensional scaling (nMDS) and analysis of similarity (ANOSIM) revealed higher species richness in control plots. The invasion effect of L. camara was the highest, followed by X. strumarium, P. hysterophorus, and B. papyrifera.

Biodiversity and plant-insect interactions in fragmented habitats: A systematic review

Fragmentation is threatening insect biodiversity and intricate interactions in various ecosystems. Ecological interactions – especially those involving plants and insects – are significantly impacted by fragmented habitats. Because of fragmentation, edge effects and reduced habitat connectivity and quality affect insect species diversity, abundance, behavior, movement, life cycles, and interactions with plants, e.g., pollination, herbivory, and seed distribution. To a large degree, ecosystem services or processes are mediated by these interactions. While fragmented habitats create suitable conditions for invasive alien plants (IAPs), such invasions modify native plant composition and herbivorous insect communities because they cause a decline or loss in insect biodiversity. A systematic review was conducted by reviewing eighty-eight (88) articles to gather evidence for fragmentation effects on insect biodiversity, insects’ behavior and adaptations, plant-insect interactions (i.e., pollination, herbivory, and seed dispersal), and its influence on IAP invasions. This review deduced that any change in insect community composition and diversity due to fragmentation can have cascading effects on ecosystem processes within habitats. It further contends that successful conservation and management of fragmented habitats requires an understanding of the intricate dynamics of plant-insect interactions. However, the long-term resilience and health of ecosystems can be guaranteed by supporting sustainable land use, improving connectivity, and restoring habitats. These actions may help stop and/or reduce the effects of fragmentation on insect biodiversity and support the livelihoods and well-being of millions of people.

In Ethiopia, Parthenium hysterophorus (P. hysterophorus) is an invasive alien plant affecting various ecosystems. P. hysterophorus displaces native plant species and causes a serious threat to biodiversity. With this background, we aimed to assess the soil seed bank of P. hysterophorus under major land use types and assess the perception of the community toward the effects of P. hysterophorus on social aspects in the lower Hare watershed. For this study, 210 soil samples were collected from 15 transect lines in grassland, cropland, and forest land use types. Statistical analysis using three-way factorial analysis of variance (ANOVA) was used to analyze the difference in density of P. hysterophorus among various land uses soil depths and sites (P < 0.05). For assessing the perception of local communities regarding the effects of P. hysterophorus, a total of 117 respondents were enrolled and semi-structured and close-ended questionnaires were used for data collection. It was found that all factors, that is, land use, site, and soil depth, significantly affected the soil seed bank density in the lower Hare watershed (P < 0.05). Results indicated that the mean density of seeds was the highest in croplands among the land use types. Meanwhile, the highest mean density of seeds was identified in 0–10 cm soil depth, but the lowest mean density of seeds was identified in 10–15 cm soil depth. The highest seeds were identified at Chano Cheliba, but the density of seeds the lowest in Kola Shera. Moreover, 38.5% of households in Kola Shera and 21.4% of households in Kola Cheliba, but 8.5% of households in Kola Doriga said that it had effects on ecosystem services such as crop yield and livestock production. There should be a need for increased awareness about the density of P. hysterophorus in various land uses and its impacts on native plant species. Seeking for possible solutions such as mechanical control methods in terms of abortion of its seed set and weeding in early vegetative period are among the local people, researchers, and extension workers can use for the management of its invasion, and appropriate control measures can be designed to combat its further invasion and impacts on different land uses of the region.
