Understanding interactions between harmful algal bloom (HAB) species and their grazers is essential for determining mechanisms of bloom proliferation and termination. We exposed the common calanoid copepod, Temora longicornis to the HAB species Alexandrium fundyense and examined effects on copepod survival, ingestion, egg production and swimming behaviour. A. fundyense was readily ingested by T...

A nationwide survey of Babesia gibsoni using Haemaphysalis longicornis collected from dogs and cats in Japan was conducted using molecular methods. A total of 1,341 H. longicornis, including 305 females, 14 males, 332 nymphs and 690 larvae (153 pools) from 44 prefectures, were examined by B. gibsoni-targeted PCR. Partial sequence analysis revealed that 12 of 13 positive samples sequenced, inclu...

We investigated microhabitat selection in the Amazonian whip spider Heterophrynus longicornis (Butler 1973). The probability of finding individuals of this species increased according to the diameter of the trees. Moreover, there was a positive correlation between the size of adult individuals and the diameter of the trees on which they were found. Our results also provide quantitative support ...

Tick-borne diseases are considered as emerging infectious diseases in humans and animals in China. In this study, Ixodes persulcatus (n = 1699), Haemaphysalis concinna (n = 412), Haemaphysalis longicornis (n = 390), Dermacentor nuttalli (n = 253), and Dermacentor silvarum (n = 204) ticks were collected by flagging from northeastern China, and detected for infection with Anaplasma, Ehrlichia, Ba...

This paper describes the diets of 201 larvae of Atlantic mackerel Scomber scombrus L. collected from Long Island Sound, New York (USA) during May-June 1982 and 1983. First-feeding larvae (3.5 mm in length) were phytophagous. The diets of larvae 4.5 mm were composed of the nauplii of Acartia hudsonica, Temora longicornis and Pseudocalanus sp. Larvae > 5 mm ate some copepodites of A. hudsonica an...

The tick-borne encephalitis virus (TBEV) serocomplex of flaviviruses consists of arboviruses that cause important diseases in animals and humans. The transmission of this group of viruses is commonly associated with tick species such as Ixodes spp., Dermacentor spp., and Hyalomma spp. In the case of Haemaphysalis longicornis, the detection and isolation of flaviviruses have been previously repo...

Tick is one of the most important arthropods in the transmission of vector-borne diseases. In this study, we investigated the abundance and species of ticks associated with swine and their habitats to assess the risk of spread of tick-borne diseases in host species, such as wild boars. Ticks were collected from 24 grazing or traditionally reared domestic pig farms and 8 habitats of wild boars i...

Introduction Conclusions References

Feeding strategies of copepods were studied during a dinoflagellate-dominated bloom in the North Sea in August 2001. The aim of this study was to evaluate the importance of mesozooplankton grazing as a biological loss factor of harmful algal blooms under natural conditions. Therefore, ingestion, egestion and egg production experiments were performed with the most abundant copepod species Calanu...
