Spectral data for analysis: Full spectra colouration and condition-dependent signalling in a skin-based carotenoid sexual ornament

Carl Soulsbury
Carotenoid-based traits commonly act as condition-dependent signals of quality to both males and females. Such colours are typically quantified using summary metrics (e.g. redness) derived by partitioning measured reflectance spectra into blocks. However perceived colouration is a product of the whole spectrum. Recently, new methods have quantified a range of environmental factors and their impact on reflection data at narrow wavebands across the whole spectrum. Using this approach, we modelled the reflectance of red integumentary...

Data and code for \"Biomechanical properties of a buzz-pollinated flower\"

Vinícius Brito, Carlos Nunes, Caíque Resende, Fernando Montealegre-Zapata & Mario Vallejo-Marín
Approximately half of all bee species use vibrations to remove pollen from plants with diverse floral morphologies. In many buzz-pollinated flowers, these mechanical vibrations generated by bees are transmitted through floral tissues, principally pollen-containing anthers, causing pollen to be ejected from small openings (pores or slits) at the tip of the stamen. Despite the importance of substrate-borne vibrations for both bees and plants, few studies to date have characterised the transmission properties of floral vibrations....

Teaching and learning in ecology: a horizon scan of emerging challenges and solutions

Zenobia Lewis, Julia Cooke, Yoseph Araya, Karen Bacon, Joanna Bagniewska, Lesley Batty, Tom Bishop, Moya Burns, Magda Charalambous, David Daversa, Liam Dougherty, Miranda Dyson, Adam Fisher, Dan Forman, Cristina Garcia, Ewan Harney, Thomas Hesselberg, Elizabeth John, Robert Knell, Kadmiel Maseyk, Alice Mauchline, Julie Peacock, Angelo Pernetto, Jeremy Pritchard, William Sutherland … & Nicholas Worsfold
We currently face significant, anthropogenic, global environmental challenges and therole of ecologists in mitigating these challenges is arguably more important than ever. Consequently there is an urgent need to recruit and train future generations of ecologists, both those whose main area is ecology, but also those involved in the geological, biological and environmental sciences. Here we present the results of a horizon scanning exercise that identified current and future challenges facing the teaching of ecology,...

Achieving Bio-Protection in New Zealand Ecosystems mesocosm data

Priestman Waller
We established 160 experimental ecosystems (mesocosms), manipulated interactions between plants, soil biota and invertebrate herbivores in a fully factorial design. Each mesocosm was grown in a 125 L pot (575 mm diameter, Fig. 1B), and comprised one of 20 unique, eight-species plant communities varying orthogonally in the proportion of exotic and woody shrub/tree species (0-100% and 0-63%, respectively). These plants were taken from a pool of 20 exotic and 19 native/endemic New Zealand plant species....

A narrow ear canal reduces sound velocity to 1 create additional acoustic inputs in a micro-scale insect ear

Fernando Montealegre-Z
Located in the forelegs, katydid ears are unique among arthropods in having outer, middle and inner component, analogous to the mammalian ear. Unlike mammals, sound is received externally, and internally via a narrow ear canal (EC) derived from the respiratory tracheal system. Inside the EC sound travels slower than in free air, causing temporal and pressure differences between external and internal inputs. The delay is suspected to arise as sound propagation changes from adiabatic to...

Categorical versus geometric morphometric approaches to characterising the evolution of morphological disparity in Osteostraci (Vertebrata, stem-Gnathostomata)

Humberto Ferron, Jenny Greenwood, Bradley Deline, Carlos Martínez Pérez, Hector Botella, Robert Sansom, Marcello Ruta & Philip Donoghue
Morphological variation (disparity) is almost invariably characterised by two non-mutually exclusive approaches: (i) quantitatively, through geometric morphometrics, and (ii) in terms of discrete, ‘cladistic’, or categorical characters. Uncertainty over the comparability of these approaches diminishes the potential to obtain nomothetic insights into the evolution of morphological disparity and the few benchmarking studies conducted so far show contrasting results. Here, we apply both approaches to characterising morphology in the stem-gnathostome clade Osteostraci in order to assess...
