“…For example, the use of highly-cognitive birds instead of primates for cognition research, facilitating the use of nonmammalian species. Use of cephalopods to determine personality differences (Carere et al, 2015) can be a realistic alternative to primate studies given the complex cognition of these invertebrates (Mather and Dickel, 2017) that involves both short-and long-term learning and engagement in behaviours such as play.…”

What’s new from the zoo? An analysis of ten years of zoo-themed research output

The modern zoo's roles command empirical enquiry to determine the effectiveness of zoos locally and globally. Ten years ago, published work identified the need for empirical research on a diverse range of species beyond charismatic zoo megafauna. We review zoo-based research published in the decade since this original recommendation. We collectively evaluate zoo-themed research papers from those working in zoos and those external to zoos but studying zoo-housed animals. By systematically searching Web of Science © for zoo-based research and performing inductive content analysis to code year, journal, study animal's taxonomic classification, and research aims and outputs we evaluate trends in zoo-themed research, contrasted with trends in species holding. Significantly more birds and fish are kept compared to mammals, reptiles and amphibians, but mammals are consistently the primary research focus. Whilst output generally rises, only for birds is a steady increase in publications apparent. Husbandry evaluation is a major aim/output, but papers on pure biology, cognition and health also feature. Most publications lead to "specific advancement of knowledge" including validation of methodologies. We show that: (1) trends in species holdings are unrelated to trends in publication; (2) zoo-themed research makes meaningful contributions to science; (3) zoo researchers should diversify their aim/output categories and chosen study species to close the persisting research gaps that we have identified. Finally, we discuss our findings in the context of evident species biases within research outputs across the broader fields of zoology, conservation and ecology.

“…The present results show that domestication of cephalopods can be done in a natural way, having a welfare-based approach in an attempt to maximize the numbers for production. We believe that the existing results are even more important since personality traits have been reported already for S. officinalis (Carere et al, 2015;Zoratto et al, 2018) and we believe that these will be soon also reported in other cephalopods.…”

“…In finfish, spontaneous spawning behavior (Mylonas et al, 2010) and reproduction performance is usually attained with moderate to large holding volumes, low stocking densities (Okumura et al, 2003;Buchet et al, 2008) and 1 female: 1 male sex ratios (Mylonas et al, 2011). Moreover, it has been recently reported that, similar to cultured sea bream (Sparus aurata) (Castanheira et al, 2013(Castanheira et al, , 2016, S. officinalis display personality traits (Carere et al, 2015;Zoratto et al, 2018) which will also influence growth and reproduction. Hence, the use of circular tanks for the breeding stock allow for enough space for cuttlefish in the bottom (growth stage) and water column (reproduction stage) and promote increased interaction between individuals during growth and reproduction (Sykes et al, 2013).…”

“…We then calculated a body condition index by applying a principal component analysis (PCA) to length, height, and weight (as e.g., in Fusani, Cardinale, Carere, & Goymann, and Kocovsky, Sullivan, Knight, & Stepien, ), which was then used for further analyses (Section ). PCA is a multivariate statistical approach that reduces the dimensionality of the dataset by replacing multiple inter‐related original variables with a few, new uncorrelated component variables called “factors.” In our case, it served to reduce multiple testing to a single variable, instead of three (for a detailed description see Giuliani et al., ; Giuliani, Zbilut, Conti, Manetti, & Miccheli, ; Carere et al., ; Mojekwu & Anumudu, ). The morphometric characteristics of the three sampling groups are shown in Table , together with those of the three groups as pooled; PCA results are shown in Table .…”

Habitat choice is defined as a nonrandom distribution of genotypes in different microhabitats. Therefore, it could exert a great impact on the genetic variance of natural populations by promoting genetic divergence, local adaptation, and may even lead to sympatric speciation. Despite this potential role in micro‐ and macro‐evolutionary processes, there is little empirical evidence that the various genotypes within a population may differ in habitat choice‐related behaviors. Here, we tested whether habitat choice may have contributed to genetic divergence within a local population of the Mediterranean killifish Aphanius fasciatus, which emerged between groups inhabiting microhabitats with different oxygen concentrations during previous field studies. In a first experiment, we studied the distribution of individuals in conditions of hypoxia and normoxia to test whether they had a different ability to shy away from a hypoxic environment; in a second experiment, we analyzed the individual behavior of fish separately in the two conditions, to verify whether they showed peculiar behavioral responses linked to a possible differential distribution. We then analyzed the six allozyme loci, whose allelic and genotypic frequencies were significantly divergent in the previous studies. In the first test, we found that the distribution of the two homozygote genotypes of the glucose‐6‐phosphate isomerase‐1 locus (GPI‐1) was significantly different between the hypoxic and the normoxic conditions. During the second test, all individuals were more active in hypoxic conditions, but the two GPI‐1 homozygotes showed a significant difference in time spent performing surface breathing, which was consistent with their distribution observed in the first experiment. These results provide evidence that individual behavioral traits, related to genetic features, may lead to a nonrandom distribution of genotypes in heterogeneous although contiguous microhabitats and, consequently, that habitat choice can play a significant role in driving the micro‐evolutionary dynamics of this species.
