A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins ( Lagenodelphis hosei ) From the Lesser AntillesNARA Subscribed
Fraser's dolphin ( Lagenodelphis hosei ) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species. This study provides the first comprehensive characterization of Fraser's dolphin whistle acoustic structure and repertoire, based on recordings from eight gro...
High similarities in dorsal fin ratios of common bottlenose dolphins ( Tursiops truncatus ) in the Caribbean SeaNARA Subscribed
Dorsal fins, one of the most notable dolphin's physical features, play important kinematic and hydrodynamic roles and are related to physiological and environmental adaptation processes. Differences in dorsal fin shape have been recently associated with geographic variation, habitat specialization between ecotypes, and ontogenetic factors. We studied dorsal fin variation across several common bottlenose dolphin populations in...
Bottlenose dolphins’ whistles are key in social communication, conveying information about conspecifics and the environment. Therefore, their study can help to infer habitat use and identify areas of concern due to human activities. Here we studied the whistles of bottlenose dolphins ( Tursiops truncatus ) in two sites of the archipelago of Bocas del Toro, Panama, that contrast in boat traffic. Almirante Bay is a site dominate...
Feeding behavior in Caribbean surgeonfishes varies across fish size, algal abundance, and habitat characteristicsNARA Subscribed
Feeding behavior of coral reef fishes often determines their species‐specific ecological roles. We studied the two most common Caribbean surgeonfishes ( Acanthurus coeruleus and Acanthurus tractus ) to examine their species‐specific grazing rates and feeding preferences and how these differed with environmental context. We quantified the feeding activity of both surgeonfishes at four spur and groove reefs in the Florida Keys,...
Summary Trichoderma arundinaceum (Ta37) and Botrytis cinerea (B05.10) produce the sesquiterpenoids harzianum A (HA) and botrydial (BOT), respectively. TaΔTri5, an HA non‐producer mutant, produces high levels of the polyketide compounds aspinolides (Asp) B and C. We analyzed the role of HA and Asp in the B. cinerea ‐ T. arundinaceum interaction, including changes in BOT production as well as transcriptomic changes of BcBOT gene...
Kuntner, M., May‐Collado, L. J. & Agnarsson, I. (2010). Phylogeny and conservation priorities of afrotherian mammals (Afrotheria, Mammalia). — Zoologica Scripta , 40 , 1–15. Phylogenies play an increasingly important role in conservation biology providing a species‐specific measure of biodiversity – evolutionary distinctiveness (ED) or phylogenetic diversity (PD) – that can help prioritize conservation effort. Currently, there...
Reexamining the Relationship Between Body Size and Tonal Signals Frequency in Whales: A Comparative Approach Using A Novel PhylogenyNARA Subscribed
A negative relationship between cetacean body size and tonal sound minimum and maximum frequencies has been demonstrated in several studies using standard statistical approaches where species are considered independent data points. Such studies, however, fail to account for known dependencies among related species—shared similarity due to common ancestry. Here we test these hypotheses by generating the most complete species le...
