When does being smart pay off? Ecology and evolution of cognition in lacertid lizards
No full textAbstract: The evolution of cognition is one of the most enigmatic topics within biology. In particular, which exact (socio-)ecological forces shape the evolution of cognition remains unclear. Both the spatial complexity and the temporal variability of the environment have been hypothesized to be major selective drivers behind cognitive evolution, but evidence from previous research is sparse and mixed. During my PhD, I studied the role of ecology in cognitive evolution, by looking at variation both across and within species of lacertid lizards. The first part of my thesis investigated cognitive variation at the intraspecific level. I looked at the evolution of relative brain size across Squamata (lizards + snakes). In contrast to expectations based on literature, brain size was unrelated to habitat complexity, and social species had relative smaller brains than solitary species. Next, I measured and compared five aspects of cognition across thirteen species of lacertid lizards. Albeit species varied considerably in their performance on all five tests, this variation was largely unrelated to differences in their ecology and life-history. The sole exception was that species from more seasonal habitats tended to exhibit lower behavioural flexibility. The second part of my PhD focused on the link between environment and cognitive variation among populations of the Aegean wall lizard (Podarcis erhardii). Wall lizards from a more seasonal island habitat performed better on a spatial learning task than conspecifics from a less variable mainland location, but also demonstrated lower cognitive flexibility. Secondly, lizards from structural complex habitats were superior spatial learners compared to lizards from more simple environments. Behavioural covariance between lizard personality and cognition was also often year- and habitat-dependent. Finally, I investigated variation at the individual level. I specifically tested whether cognition would be more advantageous in complex habitats. Lizards with known cognitive abilities and personality traits were released in large outdoor enclosures characterized by either complex or simple vegetation for 11-12 months to measure their fitness. Spatial learning and problem-solving were indeed associated with survival, albeit in unexpected ways, but there was no link between cognition and reproductive success. I also found no evidence for habitat-dependent selection on cognition. The link between ecology and cognition is thus not straightforward, and may depend on the cognitive trait and taxonomic level under investigation. Altogether, this thesis illustrates how an integrative approach, looking at both macro-evolutionary patterns and selection within species, can provide valuable new insights in the evolution of animal cognition
Laudakia vulgaris Karameta & Lymberakis & Grillitsch & Ilgaz & Avci & Kumlutaş & Candan & Wagner & Sfenthourakis & Pafilis & Poulakakis 2022
No full textLAUDAKIA VULGARIS (SONNINI & LATREILLE, 1802) STAT. NOV. Included taxa: Laudakia s. picea (Parker, 1935), L. s. brachydactyla (Haas, 1951), L. s. vulgaris (Sonnini & Latreille, 1802), L. s. salehi (Werner, 2006) and the Jordan phylogenetic subclade. Type specimen: Agama stellio vulgaris (Sonnini & Latreille, 1802), FMNH 153134 (neotype) Crochet et al. (2006) (Field Museum of Natural History, Chicago, USA). Type locality: El Amiria, Alexandria, Lower Egypt, by present neotype designation. Distribution: All localities from Egypt, Jordan, Israel and south-western and western Syria (east to Palmyra). Remarks: According to the principle of priority of the ICZN (International Code of Zoological Nomenclature), this distinct genetic lineage was named vulgaris as that is the oldest available name. It includes the morphological subspecies of L. s. picea, L. s. brachydactyla, L. s. vulgaris and L. s. salehi, as well as a new phylogenetic subclade that corresponds to the Jordan populations from the eastern side of the Wadi–Araba valley, previously reported as an unnamed subspecies. The subspecific description of the latter is under preparation, but we have to note that the subspecific status of L. s. vulgaris and L. s. salehi is ambiguous and requires further investigation.Published as part of Karameta, Emmanouela, Lymberakis, Petros, Grillitsch, Heinz, Ilgaz, Çetin, Avci, Aziz, Kumlutaş, Yusuf, Candan, Kamil, Wagner, Philipp, Sfenthourakis, Spyros, Pafilis, Panayiotis & Poulakakis, Nikos, 2022, The story of a rock-star: multilocus phylogeny and species delimitation in the starred or roughtail rock agama, Laudakia stellio (Reptilia: Agamidae), pp. 195-219 in Zoological Journal of the Linnean Society 195 (1) on page 212, DOI: 10.1093/zoolinnean/zlab107, http://zenodo.org/record/653077
Laudakia stellio S. S.
No full textLAUDAKIA STELLIO (LINNAEUS, 1758) S.S. Included taxa: Laudakia s. stellio (Linnaeus, 1758), L. s. daani (Beutler & Frör, 1980) and the subclades from the western Taurus, Symi–Kaş, Anatolia, Lebanon and Hatay, as shown in this study (Figs 2, 4). Type specimen: Laudakia stellio stellio (Linnaeus, 1758), ZFMK 2063 (neotype), Crochet et al. (2006) (Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Germany). Type locality: Delos Island, Cyclades, Greece. Distribution: All localities from Greece (Cyclades, Crete, Thessaloniki, Corfu and East Aegean islands) and Turkey, north-western Syria and northern Lebanon. Remarks: According to the principle of priority of the ICZN, this distinct genetic lineage should be named stellio because that is the oldest available name. It includes already described morphological subspecies and other cryptic lineages of Clade 2, revealed by this study: the nominal L. s. stellio and its sister Anatolia subclade, L. s. daani and its sister W Taurus–Symi–Kaş subclades, as well as the Lebanon and Hatay subclades. The subspecific status of L. s. stellio and L. s. daani is retained, while the elevation of the Lebanon and Hatay lineages to the subspecies level is under preparation.Published as part of Karameta, Emmanouela, Lymberakis, Petros, Grillitsch, Heinz, Ilgaz, Çetin, Avci, Aziz, Kumlutaş, Yusuf, Candan, Kamil, Wagner, Philipp, Sfenthourakis, Spyros, Pafilis, Panayiotis & Poulakakis, Nikos, 2022, The story of a rock-star: multilocus phylogeny and species delimitation in the starred or roughtail rock agama, Laudakia stellio (Reptilia: Agamidae), pp. 195-219 in Zoological Journal of the Linnean Society 195 (1) on page 212, DOI: 10.1093/zoolinnean/zlab107, http://zenodo.org/record/653077
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Eaten or beaten? Severe population decline of the invasive lizard Podarcis siculus (Rafinesque-Schmaltz, 1810) after an eradication project in Athens, Greece
No full textInvasive species have been recognised as an important hazard to native communities. Amongst the mitigation measures that have been proposed to confront biological invasions, eradication projects are certainly the most drastic. In this short communication, a successful eradication project against a recently established population of the Italian wall lizard (Podarcis siculus) in Athens, Greece, is reported. To this aim, the Hellenic Herpetological Society received unforeseen aid from stray cats and, possibly, from the Οcellated skink (Chalcides ocellatus) and vegetation growth. Within three years, the initial thriving P. siculus population has shrunk to very few individuals
