Habitat degradation led to local extinction of the San Francisco forktail damselfly (Ischnura gemina) in Glen Canyon Park, San Francisco, California. In this study, we reintroduced I. gemina into Glen Canyon after the damselfly’s habitat was restored. Upon release, we carried out a mark- release-recapture study to monitor the damselfly’s population dynamics. Our data were compared to two “baseline” studies on I. gemina, conducted in the park prior to the damselfly’s demise. Our recapture rates…

On the restoration of the last relict population of a dragonfly Urothemis edwardsii Selys (Libellulidae: Odonata) in the Mediterranean
TLDR
This study highlights the importance of using biological indicators in selecting host habitats for the restoration of critically threatened populations and describes the emergence of three populations of which one was restored, one resulted from successful translocation, and one established after successful colonization.
Loss of genetic connectivity and diversity in urban microreserves in a southern California endemic Jerusalem cricket (Orthoptera: Stenopelmatidae: Stenopelmatus n. sp. “santa monica”)
TLDR
Genetic connectivity among populations has been disrupted by highways and urban development, prior to declines in local population sizes, and it is emphasized that genetic connectivity can rapidly erode in fragmented landscapes and that flightless arthropods can serve as sensitive indicators for these effects.
Selected Habitats of Slimy Sculpin in Coldwater Tributaries of the Upper Mississippi River in Minnesota
Abstract Slimy sculpin Cottus cognatus are being reintroduced into coldwater streams in the upper Midwestern United States, where they were extirpated by stream degradation during the early- to
Phylogeographic Investigation of an Endangered Longhorn Beetle, Callipogon relictus (Coleoptera: Cerambycidae), in Northeast Asia: Implications for Future Restoration in Korea
TLDR
The results of the phylogenetic and population genetic analyses suggest that C. relictus populations surveyed in the present study can be used as a “source” for a future restoration and conservation program and the linear pattern of the haplotype network with a high level of haplotype and nucleotide diversities suggests that the wide range of currently fragmented populations might be the remnant of genetically diverse populations in the past.
Dragonflies and damselflies (Odonata) in urban ecosystems: A review
TLDR
The first systematic literature review conducted to evaluate both the quantity and topics of research conducted on odonates in urban ecosystems finds the need for more studies regarding behavioural ecology and life-history traits in response to urbanisation, and a need to investigate the mechanisms behind diversity trends beyond pollution.
Testing Dragonflies as Species Richness Indicators in a Fragmented Subtropical Atlantic Forest Environment
TLDR
It is argued that Odonata can already be incorporated in ongoing assessment programs in the Neotropics, which would also increase the ecological knowledge of the group and allow extrapolation to other taxa.
Mark-recapture studies and demography
TLDR
These include the effect of marking on survival and recapture rates, differences in survival between sexes and female colour morphs, the relative importance of processes in the larval and adult stages in driving population dynamics, and the contribution of local and regional processes in shaping metapopulation dynamics.
Firefly Translocation: A Case Study of Genetic and Behavioral Evaluation in Thailand
TLDR
Firefly translocation should consider flash variation between populations to prevent this potential pre-mating isolation mechanism from resulting in probable lower translocation success rates, according to evidence in Japanese fireflies.
Hybridization rate and climate change: are endangered species at risk?
TLDR
The results showed that reproductive isolation is complete in I. damula and I. demorsa and the current pattern of extinction may not continue due to the contraction in ranges of the four species, and maximum entropy models revealed a northern and westward shift and a general reduction of the potential geographic ranges.

Population structure of the rare damselfly, Ischnura gemina (Kennedy) (Odonata: Coenagrionidae)
TLDR
The population structure of the endemic San Francisco Bay Area damselfly, Ischnura gemina, is examined using mark-recapture methods and adult population estimates showed more males were present than, females, but larval counts at one site indicated only a slight excess of males.

TLDR
The initial success of this translocation suggests that efforts using these methods to establish a population of C. d.
Significance of temporal changes when designing a reservoir for conservation of dragonfly diversity
TLDR
The study shows that to maintain both high species richness and diversity, including endemics, it is essential to maintain a variety of biotopes using selective management of the marginal vegetation without allowing succession to proceed to a point where overgrowth of the bank and silting of the bottom begin to impoverish the fauna.

Odonates as Indicators of Shallow Lake Restoration by Liming: Comparing Adult and Larval Responses
TLDR
It is concluded that lake restoration by liming can reduce diversity and larval numbers among odonates and subtly affects adult assemblages, and natural recovery processes after acidification in formerly open-cast areas––rather than chemical intervention through liming––might lead to preferable conservation outcomes.

Hybridization between Two Damselfly Species (Odonata: Coenagrionidae): Morphometric and Genitalic Differentiation
TLDR
It is concluded that the inferior appendage trait is not taxonomically reliable because it fails to convey the recombinant nature of individuals in the hybrid zone, and argues for retention of full species status for both I. gemina and I. denticollis.
