“…The higher variability in the relative abundance of forest and fynbos vegetation is associated with the sudden rise of coprophilous fungi and a concomitant higher amplitude of charcoal (Figures 3c and 4), consistent with increased pastoralist activities, possibly Khoekhoen and the arrival of European settlers in the area as indicated by historical documentation (Pooley, 2014, 2018). These phases of increased disturbance (e.g.…”

“…The period from ~1750 to 1850 CE is the terminal phase of the LIA, during which time high precipitation is inferred from the Verloren Vlei diatom record (Stager et al, 2012). Historical documents provide information about the continuous demand for timber by the early settlers, which have resulted in extensive forest clearance (Pooley, 2009, 2018). This, undoubtedly, was a contributing factor to forest decline and the first signs of forest degeneration in the pollen record (Figure 3b).…”

“…It was further and more intensively altered by European settlers who increased fire activity from the mid-17th century to improve grazing for livestock (Pooley, 2014). Historical sources suggest, that after the establishment of the victualling station of the Dutch East India Company in 1652 CE (298 cal BP) areas of afrotemperate forest diminished because of intensive logging and veld burning (Pooley, 2012, 2018). This high fire frequency was followed by a steady decrease in the incidence of fire in the last 50 years (Slingsby et al, 2020) due to urban development and a policy of fire suppression implemented to protect pine plantations and property (Luger and Moll, 1993).…”

Late-Holocene fynbos-forest dynamics in Orange Kloof, Table Mountain National Park, South Africa

Fynbos and afrotemperate forest exist as alternate stable states in the Cape Floristic Region of South Africa. In parts of Table Mountain National Park, afrotemperate forest has expanded in recent decades. The aim of this project was to explore the drivers of this change and distinguish whether this expansion represents a recovery of forest after previous clearance during the 18th century or is a novel expansion of forest range that resulted from policies of fire suppression in the 20th century. To determine the relationships between forest and fynbos and its key drivers, pollen, non-pollen palynomorphs, charcoal, stable isotope ratios (δ13C) and major and trace elements were analysed from late-Holocene sediments extracted from Orange Kloof. Pollen data show that forest cover has fluctuated over the past 3690 years. At the start of the record, under drier conditions from 1670 BCE to ~170 CE, forests contracted, and dry, asteraceous fynbos dominated the landscape. Around ~170 CE there was a shift to ericaceous fynbos as water availability increased. Weak signals of Khoekhoen pastoralists may be visible in the record around 50 CE, indicated by increased spores and charcoal. A regime shift towards increased dominance of the forest occurred ~250 CE, associated with wetter climate. Clear anthropogenic signals are associated with European settlement from 1650 CE. Reinforced by human clearance of forest, fynbos expanded during the cool conditions of the late phase of Little Ice Age (~1750–1850 CE). Forest expansion in the 20th century likely reflects fire suppression and recovery from past forest clearance. Fire needs to be managed accordingly if further expansion of forest into fynbos is to be curbed.

“…Over 30 years ago, marine biological invasions were identified as one of the most serious global environmental changes ( Carlton, 1999 ; Occhipinti-Ambrogi & Savini, 2003 ). Since then, the list of non-indigenous species (NIS) in different parts of the World Ocean has grown, altering an increasing number of marine ecosystems ( Chan & Briski, 2017 ; Pooley & Queiroz, 2018 ), and expanding the scope of challenges caused by these alien species ( Simberloff et al, 2013 ; Katsanevakis et al, 2014 ).…”

Calanoid copepod Peudodiaptomus marinus Sato, 1913 was first recorded in Sevastopol Bay in the northern Black Sea in September 2016. We performed regular observations of this new invasive species between October 2016 and December 2018. We conducted bi-weekly plankton sampling at three stations located within or adjacent to Sevastopol Bay. This is the first paper to combine (i) a detailed morphological study, (ii) molecular genetic analysis, and (iii) an investigation of P. marinus seasonal dynamics and interannual abundance variability in the coastal Black Sea. Our morphological research showed similarities between Pseudodiaptomus specimens and existing P. marinus illustrations and descriptions. Our morphological analysis results were confirmed using molecular genetic studies. Based on the genetic variability of ITS2 and cytb, we found that all investigated specimens from Sevastopol Bay belonged to P. marinus. Investigations of P. marinus seasonal and interannual abundance variability showed the same seasonal patterns throughout the studied period, with a higher seasonal abundance from October to November and one pronounced density peak in autumn. The highest abundances (2,000 ind m–3 at the mouth of the bay and more than 5,000 ind m–3at its centre) were recorded in November 2018. In the samples, we found adults of both sexes, including ovigerous females, copepodites I–V, and nauplii, suggesting that the species reproduce in Sevastopol Bay. Our research indicated that P. marinus is a new non-indigenous species (NIS) in the Black Sea, and we will discuss a possible vector of its introduction into this basin.

“…The literature about the historical and social perspectives on introductions and invasions has multiplied in the last few decades, demanding interdisciplinarity (Vaz et al 2017). Not reducing narratives to a good-versus-bad battle, environmental history approaches them by capturing the cultural and natural complexities of the phenomena and revealing how these bioinvasions have unfolded (Lidström et al 2016;Pooley and Queiroz 2018).…”

An Early Bioinvasion in the Azores. Global Circulation and Local Dynamics (1840s–1860s) in Response to the Brown Soft-Scale Coccus hesperidum

Bioinvasions occurred in the past as they do in the present, raising a set of ecological, economic, cultural and scientific changes. This paper focuses on how people dealt with and overcame the introduction and spread of the brown soft scale (Coccus hesperidum) in the Azorean orange groves in the 1840s–1860s. It describes the difficulties in the detection and the identification of the causal agent, the underestimation of the impacts in the early moments, the slow response and the limitations on methods of control. This is the earliest historical case of a plant pest documented in the Azores archipelago and the first that led to regulations concerning preventive measures and control. Research results are discussed in the framework of the global transfer of living organisms, rethinking Crosby’s original model of “Europeanizing” the colonial and overseas territories in the context of the nineteenth century empires. They highlight the relevance of understanding local dynamics, which reconsider the relationship between the center and the periphery.
