Biological Diversity in Headwater Streams

Headwaters, the sources of all stream networks, provide habitats that are unique from other freshwater environments and are used by a specialised subset of aquatic species. The features of headwaters that provide special habitats include predator-free or competitor-free spaces; specific resources (particularly detrital based); and moderate variations in flows, temperature and discharge. Headwaters provide key habitats for all or some life stages for a large number of species across just about all freshwater phyla and divisions. Some features of headwaters, including isolation and small population sizes, have allowed for the evolutionary radiation of many groups of organisms within and beyond those habitats. As small and easily engineered physical spaces, headwaters are easily degraded by streambank development, ditching and even burial. Headwater streams are among the most sensitive of freshwater ecosystems due to their intimate linkage with their catchments and how easily they are impacted. As a unique ecosystem with many specialist species, headwater streams deserve better stewardship.

“…For instance, the spiketail dragonfly (Cordulegaster spp.) larvae are primarily found in headwater streams, and adults spend their lives in the forest and forest canopy [33]. The stonefly genus Scopura (Scopuridae) is restricted to small, montane streams of Japan and the Koreas [36].…”

“…Little is known about the requirements of both sexes in surrounding terrestrial habitats (Dolnỳ et al., 2014; Hykel et al., 2016; Le Naour et al., 2019) and their activity patterns in the landscape (Hykel et al., 2018). Indeed, this information is difficult to obtain for most species because of their elusive behaviour when they are away from ponds (Hykel et al., 2018; Moskowitz & May, 2017).…”

“…Radio tracking enables a large detection range but the weight of radio transmitters is an important constraint that makes them only suitable for tracking the largest dragonfly species (May & Matthews, 2008). Previous studies using this method described the migration of Anax junius for several hundreds of kilometres along the eastern coast of the U.S.A. (Knight et al., 2019; Wikelski et al., 2006) and enabled the first quantification of the home range of Anax imperator (Levett & Walls, 2011) and Cordulegaster erronea (Moskovitz & May, 2017).…”

Habitat use and movements of a large dragonfly (Odonata: Anax imperator) in a pond network

Local movements of aquatic insects within the surroundings of waterbodies aim essentially to find food, mates, resting sites, or avoid predation. Distances moved are very variable among species and may also differ depending on sex or age at the intraspecific scale. Despite a large panel of studies on odonate activities near waterbodies, little is known about their movements and behaviour in the surrounding landscape matrix. This knowledge is, however, crucial to support management schemes of pond networks and allow improvement of connectivity between them. In this study, 87 individuals of the large dragonfly Anax imperator were identified with a unique code on the wings and monitored visually on five ponds during summers 2017 and 2018. Simultaneously, 54 individuals were equipped with radio transmitters and tracked for up to 15 days. We built Cormack Jolly Seber models to test which factors are important for movement and survival of individuals, and calculated home ranges. Additionally, we performed a step selection analysis on the telemetry data to identify the terrestrial habitats selected by A. imperator at the interface between a rural area and a suburban area in north‐western France. A reduction of the survival rate was observed on the day immediately following capture regardless of the marking method. Individuals equipped with radio transmitters had a lower estimated daily survival (0.78; 95% confidence interval = 0.70–0.85) compared to wing‐marked individuals (0.89; 95% confidence interval = 0.85–0.92). Wing loading and age were the main variables influencing dragonfly survival for both methods. The probability of movement between ponds was similar for both sexes, but radio‐tracking data showed that females moved significantly further away in the landscape matrix than males, with one female detected up to 1,902 m away from the release pond. Females also had a larger home range (mean 95% kernel: 50 ha) than males (mean 95% kernel: 5 ha). Reproductive behaviour of males and flying behaviour of females were positively related to air temperature. Individuals of both sexes were present on ponds more often than in all other habitats whatever their activity. High trees were the preferred place to rest when air temperatures were low, especially for females. Overall, this study highlights the importance of integrating neighbouring trees in management schemes of ponds. It also confirms that preservation of pond networks must include on several hectares of land around ponds to meet the aquatic and terrestrial needs of amphibious organisms such as odonates. Our radio‐tracking data provide a basis for further studies on the persistence of odonate meta‐populations in fragmented landscapes.

“…Currently, the smallest available transmitter is approximately 0.2 g, which has been used to track Bombus spp. (Latreille) (Hymenoptera: Apidae) ( Hagen et al 2011 ), Corydalus cornutus (Linnaeus) (Megaloptera: Corydalidae) ( Hayashi and Nakane 1989 ), and Cordulegaster erronea (Hagen) (Odonata: Cordulegastridae) ( Moskowitz and May 2017 ). To date, however, radio telemetry has not been used to study the movements of arthropod vectors.…”

We conducted the first pilot radio telemetry study of hematophagous arthropods by placing transmitters on wild-caught triatomine insects (‘kissing bugs’), vectors of the Chagas disease parasite. In Texas—a recognized hotspot for triatomine diversity and locally-acquired human and animal Chagas disease—we tagged five female and four male Triatoma gerstaeckeri (Stål) (Hemiptera: Reduviidae), as well as one female and one male Triatoma sanguisuga (Leconte) (Hemiptera: Reduviidae) in three counties from 2015 to 2017. In comparative trials, placement of the transmitter on the dorsal side of the abdomen underneath the hemelytra wings, with the transmitter antenna shortened to 3 cm, yielded the best results. We tracked the movements of the 11 tagged bugs over an average of 4.8 d (range of 1 to 12 d) and detected 18 movement events with an average distance of 3.8 m (range of 1 to 20 m). This pilot study demonstrates the potential utility for using telemetry as a tool for studying fine-scale non-flight movement of triatomines and the discovery of cryptic resting habitats. Future studies using this or similar technologies to study movement and behavior of triatomines could test for site-fidelity of resting habitats and provide novel insight into aspects of vector biology that could be targeted in disease risk reduction efforts.
