Male sand lizards ( Lacerta agilis ) with a specific restriction fragment length polymorphism fragment in their major histocompatibility complex (MHC) genotype (‘O-males’) are more resistant to ectoparasites (a tick, Ixodes ricinus ) than are males that lack this fragment (‘NO-males’). However, emerging evidence suggests that such adaptive immune responses are costly, here manifested by reduced body condition and a compromised defence against secondary infections by haemoprotid parasites that use the ticks as vectors. Subsequent to tick encounter, O-males suffer from a higher leucocyte–erythrocyte ratio, and higher haemoprotid parasitaemia, in particular in relation to vector encounter rate. Furthermore, O-males (i.e. successful tick defenders) with more haemoprotid parasites remaining in their blood stream were in better body condition, whereas this did not apply in NO-males, demonstrating that the adaptive immunoreaction can—in the short term—be energetically even more costly than being moderately parasitized. In agreement with Zahavian handicap theory, O-males had a (marginally) higher reproductive success than males that lacked this fragment.

The Individual

We present a long-term study of epizootics in a migratory fish species that shows major advancements in our understanding of marine disease ecology. On the individual macroscopic level, Ichthyophonus hoferi infections in herring significantly reduced body condition (p < 0.01) and reproductive capacity (gonad weight, p < 0.001). Infection prevalence increased with age (p < 0.001, R adj2  = 0.71). Prevalence in the catches strongly depended on target school size and was thus higher in trawl catches. We found strong seasonality in infection prevalence within years, with peaks in summer and winter. Summer peaks spatially formed an “infectious belt” off the west coast of Norway, consisting of infected fish unable to follow the migration routes to the feeding grounds. Prevalence varied also between years (p ≤ 0.001). Since 1992, it had declined from stock prevalence levels of 10%, down to almost extinction, with another major peak in 1999. The annual peaks could best be associated with strong year classes (Pearson’s r = 0.56), a good overall body condition (r = 0.86), and plastic wintering behaviour.

Palmate Newt

A six year survey of a palmate newt (Lissotriton helveticus) population in rock pools on the west coast of Scotland indicates that this species has some tolerance of saline conditions. The newts were living with a mean salinity (conductivity) of 382 ppm (range 30.7 ppm to >4995 ppm). Other interesting observations include a variation in mating behaviour, in which normal open water behaviour is confined to crevices, and the occurrence of ‘pelvic bumps’ in some individuals that may indicate reduced body condition.

Abstract This study documents how settlement of juvenile Atlantic cod (Gadus morhua) in the Barents Sea affects otolith growth and morphology. A simple method to objectively discriminate between age 0 and age 1 cod sampled in late summer was demonstrated by using only two otolith morphometric descriptors: area and perimeter. In the pre-settled 0-group cod, otolith lobe formation clearly increased with fish size, resulting in high otolith crenulation. This trend was disrupted during settlement, resulting in noticeably less crenulated otoliths of the settled 1-group cod sampled in winter. Combined observations of otolith shape, fish size, and body condition suggest that environmental factors associated with settlement during autumn, particularly reduced food intake, directly affect lobe formation leading to less crenulated otoliths. Comparably reduced body condition and otolith crenulation of 0-group cod in bottom trawls (vs. pelagic trawls) may indicate early settlement or vertical exploratory behaviour in the Barents Sea Ecosystem Survey (in August–September) and, thus, an underrepresentation of 0-group cod from pelagic trawling.
