“…The evidence of arthropod herbivory on different fossil plant organs ( Scott, 1992 ) can be observed and quantified based on investigations of damage types on leaves ( e.g ., Müller, Wappler & Kunzmann, 2018 ), seeds ( e.g ., Barbosa dos Santos, Pinheiro & Iannuzzi, 2020 ) and wood and other indurated tissues ( e.g ., Xiao et al, 2022a , 2022b ), providing a broad variety of plant–insect interactions. Different parts of the tree may serve as hosts for different pest categories ( Wylie & Speight, 2012 : 92, Fig.…”

“…When it comes to wood, Labandeira (2005) uses the term “boring” or “borings” ( Xiao et al, 2022a , 2022b ) for the feeding groups related to endophytic phases of phytophagy in woods. Scott (1992 : 209) has distinguished wounding from boring traces, relating wounding with damage to a living plant made by an arthropod during its ectophytic phase including a plant tissue reaction, while boring is related to an alive or dead host plant serving for feeding and shelter mainly for arthropods’ endophytic phase usually without a plant reaction.…”

Premise The recognition of the Miocene Climate Optimum (MCO) in terrestrial palaeoenvironments of the Eastern Mediterranean is restricted to Lesbos and Lemnos Islands, Greece. This area is significant for its wood microfossils. A recently-discovered fossil wood assemblage from Gökçeada (Imbros) Island, Turkey, including tree species similar to the Greek findings, is thought to have an early Miocene age. Here, we revise the age of the latter plant fossiliferous locality, re-evaluate the area for the study of MCO for the terrestrial palaeoecosystems of the Eastern Mediterranean and the nomenclature errors referring to the occurrence of fossil wood. We present the plant–insect–environment interactions using detailed anatomical descriptions, of an extinct conifer and its extinct cambium miner feeding traces observed in its secondary xylem. Methods Three thin sections were prepared with standard palaeoxylotomical techniques from a small section of the silicified wood; the sections were observed under a light microscope. The anatomy of the conifer and its damage patterns were compared with those of extant and fossil Cupressaceae and Agromyzidae, respectively. Pivotal results The common anatomical features of the studied wood specimen and Hesperocyparis macrocarpa (Hartw.) Bartel and a shared characteristic (the number of the cross-field pits – a feature we consider of diagnostic value) with Xanthocyparis vietnamensis Farjon & T.H. Nguyên led to its assignment to the Hesperocyparis–Xanthocyparis–Callitropsis clade. The detailed study of the wound scars and anatomical abnormalities, the anatomical–environmental associations, and structural–functional reactions follow the identification of the wood’s anatomy sensu Carlquist providing decisive results. Conclusions Based on the distinctive characteristics presented, we identify our macrofossil as Cupressinoxylon matromnense Grambast, a stem or an extinct lineage of the Hesperocyparis–Xanthocyparis vietnamensis–Callitropsis nootkatensis clade with feeding traces of the fossil cambium miner of the genus Protophytobia Süss (Diptera: Agromyzidae), and anatomical damage and reaction tissue on adventitious shoots. The use of Protopinaceae and Pinoxylon F. H. Knowlton from the eastern Mediterranean are re–evaluated and corrections are provided. The age of the studied plant fossiliferous locality in Gökçeada is revised as middle Miocene, allowing the proposal of an eastern Mediterranean MCO hotspot, including Lesbos, Lemnos, and Gökçeada (Imbros) Islands.

“…Preservation of fossil leaves is a multiscale process that depends on a variety of environmental inputs such as climate, the site of the preserved plant assemblage, the local environment (during burial), vicissitudes of leaf damage, the chemical milieu of the plant specimens, and other factors (Behrensmeyer et al, 2000; DiMichele & Gastaldo, 2008; Greenwood & Donovan, 1991). Moreover, the observation of DTs is dependent on a fossil plant assemblage that has achieved or exceeded a threshold in which the plant specimens are sufficiently well preserved, abundant, diverse, and unbiased, and have voucher specimens deposited in an institution accessible to other researchers (e.g., Currano et al, 2021; Gunkel & Wappler, 2015; Maccracken et al, 2022; Wilf, 2008; Xiao, Labandeira, Dilcher, & Ren, 2022a, 2022b).

Plants and their insect herbivores have been a dominant component of the terrestrial ecological landscape for the past 410 million years and feature intricate evolutionary patterns and co-dependencies. A complex systems perspective allows for both detailed resolution of these evolutionary relationships as well as comparison and synthesis across systems. Using proxy data of insect herbivore damage (denoted by the damage type or DT) preserved on fossil leaves, functional bipartite network representations provide insights into how plant-insect associations depend on geological time, paleogeographical space, and environmental variables such as temperature and precipitation. However, the metrics measured from such networks are prone to sampling bias. Such sensitivity is of special concern for plant-DT association networks in paleontological settings where sampling effort is often severely limited. Here, we explore the sensitivity of functional bipartite network metrics to sampling intensity and identify sampling thresholds above which metrics appear robust to sampling effort. Across a broad range of sampling efforts, we find network metrics to be less affected by sampling bias and/or sample size than richness metrics, which are routinely used in studies of fossil plant-DT interactions.

Bipartite network metrics, which link taxa at two trophic levels, are notoriously biased when sampling is incomplete or uneven (Bluthgen et al., 2008; Dormann and Bluthgen, 2017; Frund et al., 2016). Yet a new contribution (Swain et al., 2023, henceforth SEA) claims the opposite: that bipartite network metrics are minimally sensitive to incomplete sampling and, in fact, perform better at low sample sizes than traditional richness metrics. Here I show that SEA achieved this extraordinary finding by abandoning accepted practices, including practices from the authors' previous papers.
