Assessing the effectiveness of cuttlefish traps based on lure prevalence, survival and maturity statusKostas Ganias
Trap fishing is viewed as a low impact and fuel-efficient capture technique that is drawing increasing attention. However, due to their low capture efficiency fisheries sustainability may only be attained through improving profitability of these gears. The present study attempted to provide the necessary background for the establishment of a cuttlefish trap fishery in Thermaikos gulf (E. Mediterranean), a heavily fished area by gears of questionable sustainability such as the trammel nets. This task required...
Data from: Incorporating alternative interaction modes, forbidden links and trait-based mechanisms increases the minimum trait dimensionality of ecological networksDiogenis A. Kiziridis, Lynne Boddy, Daniel C. Eastwood, Chenggui Yuan & Mike S. Fowler
Individual-level traits mediate interaction outcomes and community structure. It is important, therefore, to identify the minimum number of traits that characterise ecological networks, i.e. their 'minimum dimensionality'. Existing methods for estimating minimum dimensionality often lack three features associated with increased trait numbers: alternative interaction modes (e.g. feeding strategies such as active vs. sit-and-wait feeding), trait-mediated 'forbidden links' and a mechanistic description of interactions. Omitting these features can underestimate the trait numbers involved, and therefore, minimum...
Data from: Testing macroecological abundance patterns: the relationship between local abundance and range size, range position and climatic suitability among European vascular plantsMaria Sporbert, Petr Keil, Gunnar Seidler, Helge Bruelheide, Ute Jandt, Svetlana Aćić, Idoia Biurrun, Juan Antonio Campos, Andraž Čarni, Milan Chytrý, Renata Custerevska, Jürgen Dengler, Valentin Golub, Florian Jansen, Anna Kuzemko, Jonathan Lenoir, Corrado Marcenò, Jesper Erenskjold Moeslund, Aaron Pérez-Haase, Solvita Rūsiņa, Urban Šilc, Ioannis Tsiripidis, Vigdis Vandvik, Kiril Vassilev, Risto Virtanen … & Erik Welk
Aim: A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution in geographic and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (1) the abundance-range size relationship, (2) the abundance-range centre relationship, and (3) the abundance-suitability relationship. Location: Europe Taxon: Vascular plants Methods: Distribution range maps were extracted from the Chorological...
Evolutionary rate and genetic load in an emblematic Mediterranean tree following an ancient and prolonged population collapseSantiago C Gonzalez-Martinez, Juan Jaramillo-Correa, Francesca Bagnoli, Delphine Grivet, Bruno Fady, Filippos Aravanopoulos & Giovanni Vendramin
Severe bottlenecks significantly diminish the amount of genetic diversity and the speed at which it accumulates (i.e. evolutionary rate). They further compromise the efficiency of natural selection to eliminate deleterious variants, which may reach fixation in the surviving populations. Consequently, expanding and adapting to new environments may pose a significant challenge when strong bottlenecks result in genetic pauperization. Herein, we surveyed the patterns of nucleotide diversity, molecular adaptation and genetic load across hundreds of loci...
