Abstract

Citation: Palandacic A, Naseka A, Ramler D, Ahnelt H (2017) Corrigendum to «Contrasting morphology with molecular data: an approach to revision of species complexes based on the example of European (Cyprinidae)» by Palandačić et al. 2017. Biodiversity Data Journal 5: e21772. https://doi. Abstract This corrigendum, in the sense of the Glossary of the International Code of Zoological Nomenclature (ICZN 1999, p. 102), is to ensure that the ICZN criteria for the availability of the two new nomenclatural acts, namely the designations of the neotype of Phoxinus csikii Hankó, 1922 and the lectotype of Phoxinus marsilii Heckel, 1836, are satisfied.

Blood may buy goodwill: no evidence for a positive relationship between legal culling and poaching in Wisconsin

“…This shows that the tendency towards a negative relationship between legal state culling and population growth rates reported in [ 1 ] can be explained by the negative association between legal state culling and reproductive rates. Furthermore, if we interpret in this model as an estimate of the impact of legal state culling on poaching, the result lends support to the hypothesis that legal state culling reduces poaching, consistent with results from previous analyses of radio-tracked wolf survival in Wisconsin [ 2 ], and contrary to the conclusion in Chapron & Treves [ 1 , 6 ].…”

“…= 0.41, p = 0.03, binomial generalized linear mixed model with logit link function and year fitted as a random effect). This observed pattern in reproductive rates suggests that the tendency towards a negative relationship between legal state culling and population growth rates, interpreted as evidence of poaching by Chapron & Treves ([ 1 ], see also [ 5 , 6 ]), could alternatively be due to variation in reproductive rates. The temporal variation in reproductive rates could be owing to independent natural variation but may also have a causal component such as shooting of reproductive individuals during the legal cull [ 7 ].…”

Reply to comments by Olson et al . 2017 and Stien 2017

“…Stien [ 6 ] argues that the quadratic relationship he found for area against population size is evidence of negative density dependence. However, as we wrote previously [ 8 ], one must first demonstrate a mechanism to assert negative density dependence. Indeed, the United States Fish and Wildlife Service reported that the Wisconsin wolf population grew from minima of 746 to 866 by April 2016 [ 9 ] after all wolf-killing including tolerance hunting was barred in December 2014, or a 1-year growth of 16%, which is larger than the annual median growth during our study period.…”

Predator Control Needs a Standard of Unbiased Randomized Experiments With Cross-Over Design

“…For example, in one study (Ohrens et al, 2019a), 4 months was sufficient to reveal a statistical difference between placebo (no domestic animals attacked by pumas) and treatment (seven domestic animals attacked by pumas) but not to detect a difference for the Andean foxes nor to be confident of longterm effects (Khorozyan and Waltert, 2019). Nonetheless, we echo the sentiments of researchers calling for less adherence to traditional thresholds of significance (Amrhein et al, 2019), so even a reduction in risk equivalent to 1-2 standard deviations of the placebo control subjects might justify using or discarding a proposed treatment for predator control, regardless of the probability value generated by frequentist statistical tests (e.g., Chapron and Treves, 2017a).…”
