Identification of a female sex pheromone in Carcinus maenas (2011)
Journal Article
Hardege, J. D., Bartels-Hardege, H. D., Fletcher, N., Terschak, J. A., Harley, M., Smith, M. A., …Bublitz, R. (2011). Identification of a female sex pheromone in Carcinus maenas. Marine ecology progress series, 436, 177-189. https://doi.org/10.3354/meps09226

Despite major progress in our understanding of animal signaling systems, the identification of chemical signals in aquatic organisms is still in its infancy. Exemplary for this is the lack of structural knowledge of crustacean sex pheromones despite... Read More about Identification of a female sex pheromone in Carcinus maenas.

Analytical challenges and the development of biomarkers to measure and to monitor the effects of ocean acidification (2011)
Journal Article
Hardege, J., Rotchell, J., Terschak, J., & Greenway, G. (2011). Analytical challenges and the development of biomarkers to measure and to monitor the effects of ocean acidification. Trends in Analytical Chemistry, 30(8), 1320-1326. https://doi.org/10.1016/j.trac.2011.07.004

Changing ocean-carbonate chemistry caused by oceanic uptake of anthropogenic atmospheric carbon dioxide leads to the formation of carbonic acid, thus lowering the pH of the sea with predictions of a decrease from current levels at 8.15 to 7.82 by the...

Simultaneously hermaphroditic shrimp use lipophilic cuticular hydrocarbons as contact sex pheromones (2011)
Journal Article
Hardege, J. D., Harley, M. A., Lin, J., Terschak, J. A., & Zhang, D. (2011). Simultaneously hermaphroditic shrimp use lipophilic cuticular hydrocarbons as contact sex pheromones. PloS one, 6(4), e17720. doi:10.1371/journal.pone.0017720

Successful mating is essentially a consequence of making the right choices at the correct time. Animals use specific strategies to gain information about a potential mate, which is then applied to decision-making processes. Amongst the many informati...

The fecal odor of sick hedgehogs (Erinaceus europaeus) mediates olfactory attraction of the tick Ixodes hexagonus (2011)
Journal Article
Bunnell, T., Hanisch, K., Hardege, J. D., & Breithaupt, T. (2011). The fecal odor of sick hedgehogs (Erinaceus europaeus) mediates olfactory attraction of the tick Ixodes hexagonus. Journal of Chemical Ecology, 37(4), 340-347. https://doi.org/10.1007/s10886-011-9936-1

Parasite loads of animals vary among individuals, but the underlying mechanisms have not been fully identified. Here, we investigated whether health status of hedgehogs (Erinaceus europaeus) is correlated with tick burden, and whether chemical cues l...

New compounds, sexual differences, and age-related variations in the femoral gland secretions of the lacertid lizard Acanthodactylus boskianus (2011)
Journal Article
Khannoon, E. R., Flachsbarth, B., El-Gendy, A., Mazik, K., Hardege, J. D., & Schulz, S. (2011). New compounds, sexual differences, and age-related variations in the femoral gland secretions of the lacertid lizard Acanthodactylus boskianus. Biochemical Systematics and Ecology, 39(2), 95-101. https://doi.org/10.1016/j.bse.2011.01.008

Integumental gland secretions in lizards have been postulated to play a role as semiochemicals, but few studies have analysed the chemical nature of the gland secretions used in communication. We analysed the femoral gland secretions of Acanthodactyl...

Biological responses to contaminants in the Humber Estuary: disentangling complex relationships (2011)
Journal Article
García-Alonso, J., Greenway, G., Munshi, A., Gómez, J., Mazik, K., Knight, A. W., …Elliott, M. (2011). Biological responses to contaminants in the Humber Estuary: disentangling complex relationships. Marine environmental research, 71(4), 295-303. https://doi.org/10.1016/j.marenvres.2011.02.004

Due to the ecological importance of estuaries, it is necessary to understand the biological effects that potentially toxic contaminants induce in bioindicator species. A key aspect is whether effects at lower levels of biological organisation transfe... Read More about Biological responses to contaminants in the Humber Estuary: disentangling complex relationships.

Evidence that 1-methyl-L-tryptophan is a food-related odorant for the Senegalese sole (Solea senegalensis) (2011)
Journal Article
Velez, Z., Hubbard, P. C., Hardege, J. D., Welham, K. J., Barata, E. N., & Canário, A. V. M. (2011). Evidence that 1-methyl-L-tryptophan is a food-related odorant for the Senegalese sole (Solea senegalensis). Aquaculture, 314(1-4), 153-158. https://doi.org/10.1016/j.aquaculture.2011.01.025

Nocturnal animals often rely heavily on olfactory cues to locate their food. This is especially true for fish whose prey live buried in the substrate. The aim of the current study was to identify non-polar odorants released by the ragworm (Hediste di...
