SUMMARYDuring my third year as an undergraduate reading Zoology at Cambridge, I found a relatively large parasite inside one of the Asellus aquaticus that had been allocated to me for the afternoon's practical work. After we had failed to identify even the group of animals to which it belonged, someone suggested that I should take my find to The Molteno Institute on the Downing Site. There I was ushered into Room 3 where I first met Dr Tate. After listening to my account he looked at my specimen and said, ‘Now just one second …’ in his rich Irish accent. As I later came to know, so much of his teaching or advice began with that highly characteristic phrase. He told me that I had found an acanthocephalan worm in its intermediate host, and when I returned some days later to tell him the results of my search of the literature, he suggested that I should work on the Acanthocephala under his supervision for the Ph.D. Degree after my graduation. I never regretted for one moment my decision to take up his offer. He maintained close contact with me, as he did with all his former research students, and the last letter I received from him was dated 16 September 1985, written just a few weeks before his death on 7 November 1985 in hospital in Cork. During the 24 years of our association I was never on Christian-name terms with him. He was always ‘Dr Tate’ or, when talking with equally close mutual associates like Donald Lee, David Molyneux, John Barrett, Vaughan Southgate or Roger Tatchell, we referred to him as ‘P.T.’. He had great integrity and fairness in all that he did and an ability of seeming to know exactly what you were thinking. These attributes, coupled with his extraordinarily wide parasitological knowledge, generated our respect. He also had a delightful sense of fun and even his sarcasm was kind and gentle. Our children loved him and his steady supply of sweets for those who visited him in Room 3 and the book tokens that came without fail every Christmas were expressions of his kindness.

AbstractThe paper presents a survey of Polish malacostracan fauna. In two tables the distribution of freshwater and Baltic species is presented according to the regionalization of the country used in "Catalogus Faunae Poloniae". Figures present some interesting distributions of freshwater malacostracan taxa. Own studies as well as the review of ample literature aimed at the preparation of the successive issues of "Catalogus Faunae Poloniae" allowed to present this survey of 121 malacostracan taxa, viz., Bathynellacea - 1 species, Mysidacea - 9, Amphipoda - 50, Isopoda - 47, Tanaidacea - 1, Cumacea - 1, Euphausiacea - 1, Decapoda - 11. In inland waters 31 species and subspecies do occur (Batynellacea - 1, Mysidacea - 1, Amphipoda - 22, Isopoda - 2, Decapoda - 5). In brackish waters of the Baltic Sea and its lagoons- 54 species (Mysidacea - 8, Amphipoda - 24, Isopoda - 12, Tanaidacea - 1, Cumacea - 1, Euphausiacea - 1, Decapoda - 8). Bi-environmental species are Asellus aquaticus and Eriocheir sinensis. The land malacostracan fauna of Poland includes 4 amphipod and 34 isopod (oniscoid) taxa. The Polish malacostracan fauna is composed mainly of species that have invaded this region of Europe in the postglacial period, but the oldest, preglacial elements are subterranean amphipods (niphargids, Crangonyx) and Bathynella natans, occurring only in southern Poland. The earliest postglacial invaders of the Baltic and/or the northern lakes were glacial relict species like the Mysis relicta group, Pallasiola quadrispinosa, Monoporeia affinis and Saduria entomon. The Southern Baltic malacostracan fauna is dominated by Boreal and Arctic/(Subarctic)-boreal elements but one third of this fauna is Mediterranean-boreal or Lusitanian-boreal in origin. Inland waters were probably settled next by Gammarus lacustris, G. pulex, Synurella ambulans, Asellus aquaticus and Astacus astacus, then by later incomers, like Gammarus balcanicus. Canal constructions in the XVIIIth century helped the immigration of Ponto-Caspian elements: Corophium curvispinum and Echinogammarus ischnus. Intentionally introduced to Polish waters are Astacus leptodactylus, Orconectes limosus and Pacifastacus leniusculus; unintentionally brought along were Eriocheir sinensis and Rhithropanopeus harrisii tridentatus, as well as Talitroides alluaudi and Trichorhina tomentosa to some greenhouses.
