Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Case report: Control of intestinal nematodes in captive Chlorocebus sabaeus

Funding was provided by the Ross University School of Veterinary Medicine via the One Health Center for Zoonoses and Tropical Veterinary Medicine.There are limited data on the efficacy of antiparasitic treatments and husbandry methods to control nematode infections in captive populations of African green monkeys (AGMs), Chlorocebus sabaeus. In faecal egg count (FEC) tests, 10 of the 11 (91%) adult male AGMs captured from the large feral population on the island of St Kitts had evidence of nematode infections, mostly Capillaria (8/11, 73%), Trichuris trichiura (7/11, 64%) and strongylid species (7/11, 64%) specifically (hookworm and Trichostrongylus, 50/50), but also Strongyloides fuelleborni (1/11, 9%). When kept in individual cages with cleaning and feeding regimens to prevent reinfections and treated concurrently with ivermectin (300 mu g/kg, given subcutaneously) and albendazole (10 mg/kg, given orally) daily for 3 days, 60% (6/10) of the AGMs were negative at a follow-up FEC at 3 months and by FEC and necropsy at the end of the study 5-8 months later. One monkey appeared to have been reinfected with T. trichiura after being negative by FEC at 3 months post-treatment. Four AGMs were positive for T. trichiura at the 3 month FEC follow-up but were negative at the end of the study after one further treatment regimen. Although initially being cleared of Capillaria following treatment, three AGMs were found to be infected at the end of the study. The ivermectin and albendazole treatment regimen coupled with good husbandry practices to prevent reinfections effectively controlled nematode infections in captive AGMs.Ross University School of Veterinary Medicine via the One Health Center for Zoonoses and Tropical Veterinary Medicin

Populační dynamika ruderálních druhů ve vztahu k limitujícím podmínkám prostředí

Hlavním cílem projektu je identifikace a ocenění významu hlavních podmínek pro rozvoj expanzních druhů rostlin náročných na živiny v lesní vegetaci. Téma je rozděleno do dílčích částí: a) analýza vegetace modelových ploch a její interpretace zaměřená na expanzní druhy, ustupující druhy, indikačně významné druhy, b) stanovení zásoby živých semen v půdě (analýza semenné banky), c) analýza intenzity deště semen, d) stanovení obsahu hlavních živin a organického uhlíku v půdě, event. pomocných půdních charakteristik, e) popis světelných poměrů stanoviště, především kvantifikace celkového světelného požitku a spektrálních poměrů významných pro klíčení semen, f) popis významných spolupůsobících faktorů (vlhkostní poměry, poměry řídící akumulaci opadu, mikro a mezomorfologie stanoviště, spouštěcí faktorys - mechanické disturbance apod.), g) formulace zásad hospodaření podporující zachování biodiverzity na vybraných lokalitách

Application of the Czech Methodology of Biogeographical Landscape Differentiation in Geobiocoenological Concept – Examples from Cuba, Tasmania and Yemen

Within the area of Central Europe, and especially in the Czech Republic (and former Czechoslovakia), geobiocoenological landscape differentiation has been applied for more than 40 years to create a spatial model of the natural (potential) condition of geobiocoenoses in the landscape. Because long-term objective of geobiocoenology is to contribute to the creation of harmonic cultural landscape by gradual development of a comprehensive system of groundworks for sustainable landscape use, and as Mendel University experts work in various countries, adaptions of geobiocoenology were used also outside Europe, in tropical areas. Examples of such a work could be shown on islands such as Socotra (belonging politically to Yemen), Tasmania, and Cuba
