Izvleček. Na raziskovalnem taboru študentov biologije (RTŠB) Središče ob Dravi '97 je floristična skupina kartirala floro v kvadrantih MTB (240-250 vrst v vsakem). Nekatere zanimivejše najdbe so predstavljene v tem prispevku: Oenothera pycnocarpa in Callitriche cophocarpa sta novi vrsti za floro Slovenije. Poleg tega smo odkrili številne potencialno naturalizirane vrste (Acer negundo, Calendula officinalis, Epilobium adenocaulon in Pinus strobus), nove vrste za subpanonsko območje Slovenije in vrste z nejasno razširjenostjo v Sloveniji. Potrdili smo pojavljanje nekaterih redkih ali ogrženih vrst in nekatere od obravnavanih vrst predlagali za vključitev v Rdeči seznam (Apium repens - E, Carex strigosa - R, Centunculus minimus - E, Lythrum hyssopifolia - E, Potentilla supina - R, Rumex aquaticus - V).

Abstract. During the Student research camp Sredisce ob Dravi '97, the floristical group was mapping vascular plants in 5 quadrants of the MTB grid (240-450 species recorded per quadrant). Some of the most interesting records of plants are presented in the paper: Oenothera pycnocarpa and Callitriche cophocarpa have not been recorded in Slovenia before. In addition, we found several potentially naturalized plant species (Acer negundo, Calendula officinalis, Epilobium adenocaulon and Pinus strobus), new species for the subpannonian part of Slovenia and species with imperfectly known area of distribution. We have also confirmed occurence of several rare or endangered plant species and some of the discussed species are proposed for inclusion in the red data list (Apium repens - E, Carex strigosa - R, Centunculus minimus - E, Lythrum hyssopifolia - E, Potentilla supina - R, Rumex aquaticus - V).

Izvleček. Med 24. in 31. julijem 1997 sta bili na 16 mestih severovzhodne (subpanonske) Slovenije nabrani 102 vrsti pajkov. Ena družina, trije rodovi in trinajst vrst je novih za favno Slovenije. Prvi rezultati tretjega v seriji poskusov ocenjevanja vrstnega bogastva pajkov slovenskih gozdov pri vasi Obrež kaže, da je preiskovani gozd vrstno zmerno bogat (72-86 vrst).

Abstract. A list of 102 spider species collected between 24 and 31 July 1997 at 16 localities of north-eastern (subpannonian) Slovenia is given. One family, three genera, and thirteen species are new to the fauna of Slovenia. A preliminary result of an investigation into spider species richness, the third in a series of such experiments in Slovenian forests, indicates that the surveyed forest near the village Obrež is moderately rich in species (72-86 species).

Izvleček. Predstavljeni so rezultati dela odonatološke skupine na Raziskovalnem taboru študentov biologije Središče ob Dravi '97. Med 24. in 31. julijem 1997 je bilo na 97 lokalitetah popisanih 40 vrst kačjih pastirjev. Pregled vseh znanih objavljenih in neobjavljenih podatkov o kačjih pastirjih raziskovanega območja je pokazal, da je bilo v obdobju 1992-1998 raziskanih 128 lokalitet in da se na njih pojavlja 49 vrst kačjih pastirjev. Za raziskovano območje je novih 12 vrst: Lestes virens vestalis (Ramb.), Lestes dryas Kirb., Sympecma fusca (Vander Lind.), Anaciaeschna isosceles (Müll.), Brachytron pratense (Müll.), Gomphus vulgatissimus (L.), Cordulia aenea (L.), Somatochlora flavomaculata (Vander Lind.), Epitheca bimaculata (Charp.), Libellula fulva Müll, Sympetrum fonscolombii (Sél.) in Sympetrum depressiusculum (Sél.). Posebno pozornost z naravovarstvenega vidika zaslužijo najdbe ogroženih vrst Ophiogomphus cecilia (Fourc.) v Dravi in Leucorrhinia pectoralis (Charp.) v ribnikih v okolici Ptuja. Predlagana je vključitev vrste Anaciaeschna isosceles v kategorijo ranljivih vrst v Rdečem seznamu kačjih pastirjev (Odonata) Republike Slovenije.

Abstract. The results of the work of the odonatological group on the Student Biology Research Camp Središce ob Dravi '97 are presented. Between 24-31 July 1997 a total of 40 dragonfly species was recorded at 97 localities. A review of all known published and unpublished dragonfly records for the investigated area has shown that in the 1992-1998 period 128 localities were investigated and a list of 49 dragonfly species was compiled. Altogether 12 species viz. Lestes virens vestalis (Ramb.), Lestes dryas Kirb., Sympecma fusca (Vander Lind.), Anaciaeschna isosceles (Müll.), Brachytron pratense (Müll.), Gomphus vulgatissimus (L.), Cordulia aenea (L.), Somatochlora flavomaculata (Vander Lind.), Epitheca bimaculata (Charp.), Libellula fulva Müll, Sympetrum fonscolombii (Sél.) and Sympetrum depressiusculum (Sél.) are new for the investigated area. The records of endangered species Ophiogomphus cecilia (Fourc.) in Drava R. and of Leucorrhinia pectoralis (Charp.) in fishponds near Ptuj deserve special interest from the nature conservation point of view. Inclusion of Anaciaeschna isosceles in the Red data list of endangered dragonflies (Odonata) of Slovenia as vulnerable species is suggested.

Izvleček. V okviru skupine za dvoživke je bilo med 23. julijem in 2 avgustom 1997 na Raziskovalnem taboru študentov biologije Središče ob Dravi '97 na skupno 68 najdiščih najdenih 12 vrst dvoživk.

Abstract. The results of the work of the amphibiological group on the Student Biology Research Camp Sredisce ob Dravi '97 are presented. Of the 68 localities, 12 species of amphibians were recorded from 23 July and 2 August 1997. The main intention of the work was to survey the amphibian species and their habitats in the study area.
