“…For example, Frankliniella intonsa (Trybom, 1895) thrips pollinate Stellera chamaejasme L. plants where they also find brooding sites and food for their offspring. This close relationship drives a coevolution process that fits the life cycles of both species (Zhang et al 2021).…”

Ecological interactions play a role in promoting and maintaining biodiversity. These interactions form complex networks of interconnected species. Therefore, changes resulting from an interaction in one of the partners can have indirect consequences on subsequent interactions with other species. Since the mutualism-antagonism continuum is a gradient, a shift in the strength and sign of an interaction is possible, highlighting the dynamic nature of interaction networks. In flowering plants, a wide variety of below- and above-ground interactions are established with a single host plant. Changes in the host, derived from such interactions, can modulate the outcome of the remaining connections in both strength and sign, and the overall configuration of the network. Thus, a species can mediate community-wide consequences through its interaction with the host by altering the plant phenotype. We present a case study where a root infection has unexpected consequences on the pollination host, driving phenotypic changes. This study provides new data on the dynamism of species interactions and the importance of obtaining a global view of interaction networks. Disentangling the direct and indirect effects of interactions and their impact on the rest of the interactions in wild communities is essential for a good understanding of the evolutionary and ecological mechanisms that promote and maintain biodiversity.

The expansive Himalayan-Hengduan Mountains (HM) and Qinghai-Tibet Plateau (QTP) form a biodiversity hotspot imperiled by global change. The species diversity, resulting from myriad factors led to plant diversification from 10 million years ago till now. However, despite understanding speciation timing better, a lack of in-depth population-level studies and a dearth of organismal sampling among closely related species and populations leaves an incomplete view of diversification trends and biotic influences. We delve into the complex factors influencing diversification through genomic and eco-morphological analysis within the Stellera chamaejasme L. complex, known for its significant floral diversity. Our results uncover four cryptic species, indicating a more recent and younger diversification period (~2.67-0.9 Mya), driven by Pleistocene glaciation and a complex set of interacting biotic factors. These factors prompted allopatric speciation and advocated cyclical warming-cooling episodes along latitudinal and altitudinal gradients throughout the Pleistocene. The study emphasizes the existence of cryptic species within these mountains, broadening our understanding of species diversification to more recent than previously recognized. This novel perspective may reshape evolutionary paradigms in plant science. Additionally, it also brings to light concerns over future warming's possible impacts on alpine species distribution and speciation, underlining the urgency for increased conservation efforts.

The mountains of Southwest China comprise a significant large mountain range and biodiversity hotspot imperiled by global climate change. The high species diversity in this mountain system has long been attributed to a complex set of factors, and recent large‐scale macroevolutionary investigations have placed a broad timeline on plant diversification that stretches from 10 million years ago (Mya) to the present. Despite our increasing understanding of the temporal mode of speciation, finer‐scale population‐level investigations are lacking to better refine these temporal trends and illuminate the abiotic and biotic influences of cryptic speciation. This is largely due to the dearth of organismal sampling among closely related species and populations, spanning the incredible size and topological heterogeneity of this region. Our study dives into these evolutionary dynamics of speciation using genomic and eco‐morphological data of Stellera chamaejasme L. We identified four previously unrecognized cryptic species having indistinct morphological traits and large metapopulation of evolving lineages, suggesting a more recent diversification (~2.67–0.90 Mya), largely influenced by Pleistocene glaciation and biotic factors. These factors likely influenced allopatric speciation and advocated cyclical warming–cooling episodes along elevational gradients during the Pleistocene. The study refines the evolutionary timeline to be much younger than previously implicated and raises the concern that projected future warming may influence the alpine species diversity, necessitating increased conservation efforts.
