“…factors, including differences between the studies in species composition, sampling protocols, sample completeness, and the time period and duration of sampling periods. Other studies in Central Amazonia found higher tiger beetle richness in TF forests (Adis et al 1998;Zerm et al 2001;Adis and Junk 2002). In our study, all four Cicindelini species occurred in both FP and TF forests but significantly more cicindelid individuals were collected from TF forest.…”

“…In our study, all four Cicindelini species occurred in both FP and TF forests but significantly more cicindelid individuals were collected from TF forest. Some studies from other parts of the Amazon reported higher tiger beetle abundance in TF forests (Zerm et al 2001;Adis and Junk 2002), in contrast higher abundance has also been reported in FP forests (Pearson and Derr 1986;Lamarre et al 2016). Thus, the data are insufficient to suggest a general abundance pattern for Cicindelini occurring in these two Amazonian forest types.…”

“…Near Manaus, Brazil, Zerm et al (2001) reported only two of 25 tiger beetle species occurring at both FP and TF forest sites. Unique species assemblages for FP and TF forests has been recorded for tropical vegetation (ter Steege et al 2000;Bredin et al 2020), birds (Remsen and Parker 1983;van Lieshout et al 2016), understory arthropods (Adis and Junk 2002;Lamarre et al 2016), canopy arthropods (Erwin 1983b;Adis et al 2010), spiders (Höffer 1997), and understory tiger beetles (Zerm et al 2001). Differences in species assemblages may relate to factors such as flooding regime adaptions, differences in plant composition, forest structure, and resource availability between FP and TF forests.…”

“…Few ecological studies have compared understory arthropod diversity and species assemblages from different forest types within Amazonia (Adis 1981;Pearson and Derr 1986;Majer and Delabie 1994;Zerm et al 2001;Mertl et al 2009;Lamarre et al 2016;Santos-Silva et al 2018). Even fewer report forest understory diversity and community data for the highly diverse Carabidae (Irmler 1979a, b;Zerm et al 2001;Lamarre et al 2016;Cajaiba et al 2018), which includes a range of trophic roles including predaceous, predominately phytophagous and omnivorous species as well as some with specialized modes of nutrition (Thiele 1977;Lövei and Sunderland 1996). Current knowledge of Amazonian carabids in the understory of FP forests is largely based on research within Central Amazonia where flooded forests are annually inundated by several meters of water for several months a year (Irmler 1979a, b;Adis 1981;Paarmann et al 1982;Zerm et al 2001).…”

Although tropical regions harbor the greatest arthropod diversity on Earth, the majority of species are taxonomically and scientifically unknown. Furthermore, how they are organized into functional communities and distributed among habitats is mostly unstudied. Here we examine species richness, diversity, and community composition of carabid beetles (Coleoptera: Carabidae) and compare them between flooded (FP) and non-flooded terra firme (TF) forests in the Yasuní area of Ecuador. The forest understory was sampled using flight intercept traps (FITs) and systematic hand collections at night in June and July 2011 and 2012, and FITs in October and November 2011. A total of 1,255 Carabidae representing 20 tribes, 54 genera, and 143 morphospecies was collected. Mean number of individuals and mean species richness did not differ significantly between FP and TF; however, numbers of Cicindelini (tiger beetles) and Pentagonicini were higher in TF forest while numbers of Lachnophorini and Scaritini were higher in FP forest. Overall, FP had significantly higher rarefied richness but extrapolation of rarefaction curves using the Chao1 nonparametric diversity estimator show that this difference may decrease with additional sampling. The inverse Simpson index was significantly higher for FP than TF forest. Nonmetric multidimensional scaling (NMDS) ordination and dissimilarity coefficient values show that FP and TF forests maintain unique assemblages with minimal overlap in community composition. Given ongoing anthropogenic pressures, particularly petroleum extraction, and those resulting from climate change, a greater understanding of the richness, diversity and community assemblages of Yasuní rainforest are needed to better conserve the fauna of this megadiverse area of Amazonia.

Two to four species of tiger beetles co-occur in coastal habitats of Japan. We have already demonstrated that co-occurring species exhibit interspecific size differences in adult mandible length, suggesting food resource partitioning with respect to prey size. In the present study, we investigated the larval microhabitats of six coastal species to examine whether spatial segregation occurs during the larval stage. The larvae of each species were found in specific microhabitats: Cicindelalewisii occurred at tidal flats, Abroscelis anchoralis at beaches, Chaetodera laetescripta at coastal dunes, and Lophyridia angulata at riverbanks in estuaries. Larvae of two congeners occurred in very different microhabitats: Callytron inspecularis at reed beds formed in tidal flats in estuaries and C. yuasai either in rock crevices, where the soil had built up, or at clay cliffs. These larval microhabitats differed among species in terms of vegetation cover, salinity, and soil texture. The larvae of four species (C. lewisii, A. anchoralis, C. inspecularis, and C. yuasai) were found at sites exposed to seawater, suggesting a tolerance to salinity. Additionally, we found differences in adult limb proportion among species. These differences seemed to be adapted to soil types in the larval microhabitats. Finally, we discuss the patterns of species assemblage of coastal tiger beetles in terms of habitat selection associated with microhabitat specificity during the larval stage and interspecific interaction associated with adult mandible size.

Survival of Seasonal Flooding in the Amazon by the Terrestrial Insect Conotrachelus dubiae O’Brien & Couturier (Coleoptera: Curculionidae), a Pest of the Camu-Camu Plant, Myrciaria dubia (Myrtaceae)

The weevil Conotrachelus dubiae O'Brien & Couturier (Coleoptera: Curculionidae) is a pest of an economically important Amazonian fruit tree Myrciaria dubia (Myrtaceae). This tree grows in seasonally flooded environments, and how weevil larvae survive flooding has not been studied. From December 2004 to May 2009, five experiments were conducted in natural conditions and in the laboratory, with the aim of understanding the mechanisms that allow the survival of C. dubiae larvae in seasonal floods in Amazonia. The larvae of C. dubiae were kept under water for over 93 days. Older instars exposed to periodic circulation of water survived better than younger instars in addition to all larvae that were kept continuously under uncirculated water. Individuals that were collected from plots of M. dubia located in flooded soils and non-flooded soils did not exhibit statistically significant differences in their levels of survival indicating that the variation in survival of flooding events is due to phenotypic plasticity of the species and not to local adaptation by the populations in different environments. We speculate that larvae can survive floods without major physiological changes as larvae appear to obtain oxygen from water by cutaneous diffusion, assisted by caudal movements.
