Abstract

Background

The Gorongosa National Park (Mozambique) is one of the most emblematic protected areas in Africa, well known for its vertebrate biodiversity and restoration ecology efforts following the Mozambican civil war in 1992. The invertebrate biodiversity of Gorongosa National Park is still poorly studied, although the scarce information available indicates the existence of a rich number of species, namely in the case of tiger- and ground-beetles (Coleoptera, Caraboidea). Moreover, the study of arthropod assemblages is key for designing conservation practices since they are potentially accurate biodiversity and ecological indicators. Hence, the diversity assessment of Caraboidea beetles using standardised methodologies is likely to provide a new insight for future conservation planning and help to quantify the effects of climate change in areas identified as vulnerable to anthropogenic pressures, such as the Gorongosa National Park.

New information

We report the occurrence of five tiger beetles (Cicindelidae) and 93 ground-beetles (Carabidae) species/morphospecies in Gorongosa National Park from a field survey funded by the ECOASSESS project. Sampling was performed in the four main habitat types present in the Park (miombo tropical forest, mixed dry forest, transitional forest and grasslands) between 25 October and 25 November 2019. In this sampling window, the turnover of Caraboidea species from the dry season to the wet season was recorded for the first time. Twenty-eight species of ground-beetles are new records to Mozambique, including three new subgenera and three new genera. Additional information on species phenology and habitat preferences is also provided.

Introduction

Mozambique is a large southern African country covered mostly by a miombo-type of savannah, dominated by Caesalpinioideae woodlands (Malmer 2007), while true forests comprise a minor area, such as the rain forests on the slopes of Mount Gorongosa (e.g. White (1983)). The major threats to Mozambican ecosystems and biodiversity include, amongst others, natural resources overexploitation, habitat fragmentation, fires and pollution (Timberlake 2000). Yet, since the end of the Mozambican civil war in 1992 - and particularly after 2005 - the Gorongosa National Park (GNP) has become a key protected area for biodiversity conservation and wildlife restoration with special focus on emblematic megafauna (Dunham 2004, Stalmans 2012, Bouley et al. 2018, Branco 2018, Bouley et al. 2021). GNP comprises a heterogeneous landscape with four main habitats in the low plateau of the Park, namely miombo tropical forest, mixed dry forest, grassland and transitional forest (Stalmans et al. 2019). These habitat types are subjected to marked seasonal changes due to the annual flooding of Lake Urema in the wet season. This contrasting seasonality greatly influences the GNP landscape and dynamics of wildlife (Bohme 2005, Beilfuss et al. 2007), particularly the biodiversity of soil fauna.

Several environmental and human-related pressures are potential threats to soil fauna communities of Gorongosa. Flooding dynamics and landscape configuration in GNP could experience dramatic alterations due to the effects of climate change. An increase in the intensity and duration of the dry season, as well as more frequent extreme events (e.g. heat waves and heavy rainfalls) have been observed recently and are expected to increase in the next decades (Hulme et al. 2001, Beilfuss et al. 2007, Tadross 2009, Niang et al. 2014, Jinga 2019, Engdaw et al. 2022). A decrease in vegetation cover is occurring throughout the Sofala Province where the Park is situated (World Food Programme 2018) and two of the three most common trees in the GNP are highly susceptible to longer dry periods (Massad and Castigo 2016). Human presence around the Park is also a driving pressure. Agricultural and deforestation practices on the Gorongosa Mountain contribute to the deterioration of the hydrological system that feeds the GNP (Beilfuss et al. 2007, Walker 2015). Soil fauna and, particularly, Caraboidea beetles, will be strongly influenced by direct and indirect effects of climatic changes such as alterations in habitat structure and composition and in abiotic conditions, like air temperature, soil moisture and erosion events (Brandmayr and Pizzolotto 2016, Knisley et al. 2016, Jaskuła et al. 2019, Kirichenko-Babko et al. 2020, Avtaeva et al. 2021). Therefore, monitoring studies in climatically vulnerable areas are determinants to evaluate the effects of future climate change on Caraboidea diversity and community composition in GNP.

Caraboidea beetles encompass more than 40,000 known species worldwide (Desender et al. 1994, Lövei and Sunderland 1996, Lorenz 2019). Tiger- and ground-beetles can have a wide variety of ecological roles and feeding habits (Kotze et al. 2011), comprising carnivorous, herbivorous and omnivorous species, i.e. occupying a large range of trophic levels (Johnson and Cameron 1969,Honek et al. 2003, Riddick 2008). Consequently, they have been used as model organisms and as ecological and biodiversity bioindicators in rapid assessments and monitoring studies in the Nearctic and Palearctic Regions (Desender et al. 1994, Pearson and Cassola 2007, Work et al. 2008, Lemić et al. 2017, Mazzei et al. 2017, Cherine et al. 2019). Yet, only a few studies have addressed standardised biodiversity studies focusing on Caraboidea communities, in tropical ecosystems from the southern African region (e.g. Samways et al. (1996), Lawes et al. (2005)). The entomofauna of Mozambique, including the Caraboidea, has been studied since the middle of the 19th century and most of the insect specimens were collected under zoological/entomological expeditions carried out by institutions or by individual persons (e.g. travellers, missionaries, naturalists). Caraboidea material collected is, therefore, scattered and usually reported as new records or new taxa in several publications and monographic works (e.g. Klug (1853), Péringuey (1896), Basilewsky(a) (1950), Basilewsky(b) (1950), Basilewsky (1951), Straneo (1958), Basilewsky (1963), Lecordier(a) (1978), Lecordier(b) (1978), Schüle (2004), Cassola and Bouyer (2007), Schüle (2011), Kleinfeld and Puchner (2012), Serrano (2014)), but never in consistent and systematic focused works. In this pioneering study, we aimed to increase the knowledge on Caraboidea beetle diversity in the four main habitats of the GNP. The results will provide the baseline data that could improve future monitoring programmes on Caraboidea diversity and community changes, leading to a better design of conservation strategies and evaluating the impacts of climate change on GNP.

General description

Purpose: 

Our main goal was to assess the soil fauna diversity in the main habitat types of the low plateau of Gorongosa National Park (GNP). Several invertebrate assemblages were surveyed, concretely as Annelida, Collembola, Formicidae, Tenebrionidae, Scarabaeoidea and Caraboidea (Coleoptera, Cicindelidae, Carabidae). The final aim was to increase the knowledge on the Caraboidea fauna associated with different habitat types, building a baseline to support further studies on tiger- and ground-beetle diversity trends and community changes in future monitoring programmes (e.g. to assess the effects of climate change and other anthropogenic disturbances).

Caraboidea from Gorongosa National Park

Study area description: 

Fieldwork was carried out in the main habitat types covering the low plateau of the GNP, namely the miombo forest, mixed dry forest, transitional forest and grasslands (Stalmans and Beilfuss 2008). GNP is located in the centre of Mozambique, occupying around 4000 km2 of the Sofala Province (Stalmans et al. 2019) (Fig. 1) with altitudes ranging from 15-80 m in the valley to 300-400 m above sea level in the hills surrounding the basin (Stalmans et al. 2019). This region has a tropical climate with mean annual precipitation of 700-900 mm, along with two distinct seasons (dry and wet). Between 2000 and 2016, a decrease in precipitation was recorded in Gorongosa (Herrero et al. 2020). GNP annual temperatures range between 15º and 30ºC, with warmer temperatures usually recorded in the wet season (Herrero et al. 2020). This rainy season occurs in the months of November to April and is associated with heavy rainfall, resulting in extensive flooding around Lake Urema, located in the centre of the low plateau. In this low plateau of the Park (“lower Gorongosa”), the dominant habitat types range from open savannahs (grasslands) to mixed savannahs (transitional forests) and forested habitat types comprising mixed forests and miombo forests. The latter is dominated by trees of the genus Brachystegia (Herrero et al. 2020).

Sampling methods

Description: 

ECOASSESS survey focused on the four main habitat types, i.e. miombo tropical forest, mixed dry forest, transition forest and grasslands (Fig. 2), encompassing the low plateau of the Gorongosa National Park, in a total sampling area of 56,130 m2. These habitats were selected considering the ecosystem changes and complex dynamics due to seasonal flooding and human disturbance in this area of the Park. Within each habitat type, 25 sampling plots were randomly distributed (Fig. 3), with a minimum distance of 1 km between each other (Table 1).

Sampling description: 

Caraboidea beetle sampling was done through the use of pitfall traps (Drift 1951, Greenslade 1964). In each sampling plot, three pitfall traps were arranged in the shape of a triangle with 5 m of separation between them. Pitfall traps consisted of plastic cups with 10 cm diameter and filled with ethyleneglycol (5%). To include data from the transition between the dry and wet seasons, Caraboidea beetles were collected during three sampling periods: T1 (25 October to 5 November of 2019) and T2 (5-15 November of 2019), both during the dry season and T3 (15-25 November of 2019) in the wet season, comprising ten days per sampling window. During pitfall sampling, the content of each pitfall was enclosed in a cloth bag and all bags were put together in jerricans filled with 96% ethanol. Afterwards, all jerricans were transported to the laboratory at the Centre for Ecology, Evolution and Environmental Changes (University of Lisbon, Portugal) for sorting and taxonomic identification of Caraboidea beetle specimens. All other taxa were separated and stored in 75% ethanol for further possible studies. Taxonomic identification was performed to the species/subspecies level or morphospecies. Data from pitfall sub-samples were then pooled before data analyses.

Quality control: 

All carabid and cicindelid specimens were taxonomically identified by Artur R. M. Serrano. Whenever possible, the identification was made to the subspecies or species level, otherwise, the specimens were separated as morphospecies.

Description: 

Our project reported the occurrence of five tiger-beetles (Cicindelidae) and 93 species/morphospecies of ground-beetles (Carabidae) in Gorongosa National Park, ascertained through a field survey supported by the ECOASSESS project. The sampling activities were conducted between 25 October and 25 November, encompassing the Park's four principal habitat types, namely miombo tropical forest, mixed dry forest, transitional forest and grasslands. This survey period allowed us to document, for the first time, the changes in Caraboidea species diversity from the dry season to the wet season. Amongst the noteworthy records are 28 ground-beetle species that represent new records for Mozambique, including three novel subgenera and three previously unrecorded genera. Furthermore, we offer supplementary insights into species phenology and habitat preferences.

The dataset submitted to GBIF is structured as a sample event dataset, with two tables: event (as core) and occurrences. The data in this sampling event resource have been published as a Darwin Core Archive (DwC-A), which is a standardised format for sharing biodiversity data as a set of one or more data tables. The core data tables contain 403 event and 838 occurrence records (Serrano et al. 2023).

Additional information

Results

A total of 1777 Caraboidea beetle specimens were identified, of which 1765 were identified to species or subspecies. They were from 98 different species/morphospecies (5 Cicindelidae and 93 Carabidae) (Table 2, Serrano et al. (2023)). Only 785 out of the 900 pitfalls were collected (Table 3), either due to trap destruction or plot inaccessibility in the wet season due to flooding. Considering the last checklist including information on Mozambique Caraboidea (Lorenz 2019), there are three genera (Apristus Chaudoir, 1846; Platytarus Fairmaire, 1850; Crepidogastrillus Basilewsky, 1959), three subgenera (Klugipaussus Kolbe, 1927; Tyronia Liebke, 1934; Trechicus LeConte, 1853) and 28 species/subspecies that are new records for this country (Table 2). Additionally,, most of the species/subspecies sampled in this study had never been recorded for GNP and of the few that were, it was only for the Chitengo area (e.g. Alves (1974), Schüle (2011)).

New records at the Species, Subgenus or Genus levels are also provided (Sp, SbG and G, respectively). The first five species belong to the family Cicindelidae and so they are not included in any subfamily.

Licininae and Lebiinae were the two Caraboidea subfamilies recording the highest number of species (15 species each), while the most abundant specimens belonged to the subfamily Brachininae (third most speciose with 12 species). The most abundant genera were Pheropsophus Solier, 1833 (Brachininae), Microlestes Schmidt-Goebel, 1846 (Lebiinae), Chlaenius Bonelli, 1810 (Licininae) and Abacetus Dejean, 1828 (Pterostichinae) (Table 2). At the species level, Microlestes zambezianus (Mateu, 1960) (Lebiinae) and Pheropsophus mashunus (Péringuey, 1896) (Brachininae) were the most abundant, while Chlaenius conformis (Dejean, 1831), Phesopsorus insignis insignis (Boheman, 1848) and Graphipterus tristis (Klug, 1853) were the most well-represented, i.e. the only ones present across all habitat types (Table 2).

A considerable number of caraboid species were recorded only once (39 singletons, comprising 39.8% of the total assemblage) or twice (6 doubletons, comprising 6.1% of the total assemblage), indicating that almost 50% of the Caraboidea sampled in the GNP are rare species. The presence of rare species (singletons and doubletons) was common across all habitat types, but their number was highest in the mixed and transitional forests (Table 2). On the other hand, we found that two to five species were generally dominant in the Caraboidea assemblages, but species identity varied amongst habitat types (Table 2).

Transitional forest recorded the highest number in Caraboidea specimens (Table 3), with the dominance of P. insignis insignis, P. mashunus, Distichus picicornis (Dejean. 1831), Tetragonoderus immaculatus LaFerté-Sénectère, 1853, Microlestes flavipes micromys Alluaud, 1918 and M. zambezianus. Grassland recorded the second highest amount of Caraboidea specimens, with D. picicornis, Abacetus perturbator Péringuey, 1899, Chlaenius discopictus nuncius Péringuey, 1908 and also M. zambezianus as the most abundant species. Mixed dry forest was the third habitat type in terms of number of specimens of Caraboidea collected in pitfalls, with the dominance of Crepidogaster langenhani, Scarites tenebricosus molossus Klug, 1853, Abacetus percoides Fairmaire, 1868 and Orthotrichus insolitum (Péringuey 1896). Miombo forest recorded the lowest number of Caraboidea specimens (Table 3) and Crepidogaster langenhani Liebke, 1927 as well as P. mashunus were the dominant species in this habitat type.

Amongst the 98 species/subspecies recorded in this study, only a total of 24 were found across the three sampling seasons. The wet season recorded the highest absolute values in species numbers across habitats, but the abundance values in pitfalls varied according to the habitat type (Table 3). Only miombo and mixed dry forests recorded a similar pattern between abundance and species numbers found in the pitfall traps.

Our results contribute to fill the gap in the description of Caraboidea communities across the main habitat types of the GNP, setting the stage for the creation of baseline data for future assessments and comparisons with other studies. Our survey also provides a reference values for individual species that could support conservation schemes aiming to evaluate the effects of climate change on richness and diversity patterns of Caraboidea beetles in GNP.
