Two hundred and eighty-one anisakid larvae were found encapsulated in stomachs and mesenteries of 69 blackspot seabreams, Pagellus bogaraveo from Madeiran waters. Ninety-four larvae were identified as Anisakis simplex s.s., Anisakis pegreffii (Type I larvae), Anisakis simplex s.l. (Type II larvae) and Hysterothylacium sp. Prevalence of infection with anisakids increased with host length from 81.3% to a maximum of 96.3%. Mean intensity ranged from 3.5 (at length class 25 cm) to 4.8 (at length class 35 cm), with the majority of fish infected with only 1 or 2 parasites. A positive but not significant correlation was found between intensity and length (rₛ = 0.0419, p = 0.717). The high values of prevalence and low values of intensity may indicate that the anisakid larvae are dispersed within their hosts. No particular histopathological lesions were found associated with the presence of the nematodes, corroborated by a positive but not significant correlation that was found between intensity and condition factor (rₛ = 0.242, p = 0.035).

The smalleyed rabbitfish, Hydrolagus affinis (de Brito Capello, 1868) (Chimaeridae), is recorded from the archipelago of Madeira for the first time, based on seven specimens caught between 1200 and 2500 m depth. This record extends the previously known range of distribution of this species, and also confirms its vertical distribution down to 2500 m. Additional material collected from the Canary Islands and the Azores was used for comparison.

The pollinic spectrum of the Madeira region is dominated by grass pollen, which also represents an important aeroallergen in Europe. The present work aims to analyze the main features of the Poaceae pollen season in the Madeira region to determine the allergic risk. The study took place in Funchal city, the capital of Madeira Island, over a period of 10 years (2003–2012). The airborne pollen monitoring was carried out with a Hirst type volumetric trap, following well-established guidelines. In the atmosphere of Funchal, the mean annual Poaceae pollen index was 229. The mean Poaceae pollen season lasts 275 days, with an onset date in January/March and an end date in November/December. Poaceae counts showed a seasonal variation with 2 distinct peaks: a higher peak between March and June, and the second one in autumn. The peak values occurred mainly between April and June, and the highest peak was 93 grains/m3, detected on the 27th May of 2010. The Poaceae pollen remaining at low levels during the whole growing season, presenting a nil to low allergenic risk during most of the study period. Higher critical levels of allergens have been revealed after 2006. In general, the pollen risk from Poaceae lasted only a few days per year, despite the very long pollen season and the abundance of grasses in the landscape of Madeira Island.

The endohelminth parasite fauna of a deep water shark, the leafscale gulper shark, Centrophorus squamosus, examined from Madeiran waters, from September 2009 to January 2010, consisted of larval and juvenile cestodes of two orders, namely Trypanorhyncha and Tetraphyllidea, and L3 stages of Anisakis spp. Infection with Anisakis spp. could be due to the shark’s opportunistic feeding on squids and black-scabbard fish, Aphanopus carbo, which is heavily parasitized by Anisakis spp. in Madeira waters. The occurrence of larval and juvenile cestodes only, in this shark, suggests that the leafscale gulper shark features as a paratenic or a dead-end host for the parasites.

To determine allele frequencies, surveys of coat phenotypes of domestic cats were conducted in Madeira Island (Madeira archipelago) and Flores Island (Azores archi­pelago). The samples fitted a 1:1 sex ratio and panmitic populations were assumed based on the analysis of the O locus. The genetic profiles were compared to those from other Atlantic littoral populations and a marked deviation was detected at Flores Island referring to very high values of d, XV and I alleles. The differences were interpreted as indicating that cats from Flores may reflect the condition of continental cats in former times. The Madeira population is more similar to Western Europe probably due to more close and continual contact in recent years.

While investigating the nematode parasites of commercial fish caught off the coast of Madeira Island (Atlantic Ocean, Portugal), we collected five specimens of Oncophora melanocephala (Rudolphi, 1819) (Nematoda, Camallanidae) infecting the chub mackerel Scomber japonicus Houttuyn. This is the first record of O. melanocephala from chub mackerel and a new geographic record. Four additional larval specimens with developing buccal capsules were found in the chub mackerel examined.

Feral cats Felis catus Linnaeus, 1758 have contributed to the extinction of numerous native species on islands, which are clearly sources of global biodiversity. We studied the diet of this introduced predator in the Madeira and Cape Verde archipelagos, which harbour important colonies of endangered seabirds in the high mountain habitats, and compared the results with those obtained in the same habitat in the Canary Islands, Macaronesian archipelago. On Madeira, 461 prey were identified from 143 scat groups. Mammals, overall mice, constituted the basic diet appearing in 95% of cat scats. On Fogo (Cape Verde), 657 prey items were obtained from 145 scats, and mammals were also the most important prey, reaching a frequency of occurrence of 88%. Although introduced mammals were the main prey category on all Macaronesian islands, we observed variation in feral cat diet among these islands. Birds were more frequently consumed on Madeira, lizards on Tenerife (Canaries) and invertebrates on Fogo. No specific differences were observed in relation to La Palma. We suggest that the diet composition on these islands varies according to the respective availability of the different prey types.

Males and females of the acanthocephalan Rhadinorhynchus pristis Rudolphi, 1802, were found in the intestine of several chub mackerels, Scomber japonicus Houttuyn, 1782, caught at Madeira, Atlantic Ocean. Prevalence of infection was 50.6% in 1999 (n = 154) and 60.0% in 2001 (n = 30) and intensity of infection was 3.19 ± 3.84 and 3.056 ± 2.92, respectively. R. pristis showed an aggregated distribution as indicated by the aggregation and discrepancy indices 0.72 and 0.627, respectively. Comparisons of prevalences by Fisher's exact test showed no significant differences between the two samples and no significant relationship between abundance of infection and fish length. The presence of R. pristis in S. japonicus from Madeiran waters provides further evidence of relationships between the Madeiran parasite fauna and those of the western tropical Atlantic and the Mediterranean-Atlantic regions.
