A fundamental question for all vocal communication systems concerns the relationship between the developmental processes of vocal differentiation and auditory perception during ontogenetic development. Such developmental processes have been well documented in birds and mammals but poorly investigated in other vertebrates. Fish represent the oldest and largest extant vertebrate group. Besides, neural circuitry controlling vocal behavior is thought to have evolved from conserved brain areas that originated in this taxon, which makes this group key to understanding the evolution and development of the vertebrate vocal-auditory systems. However, the relationship between the vocal motor and auditory systems during development for social communication in fish remains unclear.

The goals of this study were: 1) examine how vocal behavior develops during ontogeny; and 2) compare auditory sensitivity of the saccule (main auditory endorgan) across developmental stages in the Lusitanian toadfish, Halobatrachus didactylus (Batrachoididae). This teleost species has become an interesting model to investigate questions related to vocal communication due to its unusual complex vocal repertoire and early vocal onset. Vocalizations were recorded during social interactions for four size groups (fry: <2 cm; small juveniles: 2–4 cm; large juveniles: 5–7 cm; adults >25 cm, standard length). Auditory sensitivity of juveniles and adults was determined based on evoked potentials recorded from populations of saccular hair cells in response to pure tones of 75–945 Hz.

We found an ontogenetic increment in the vocal repertoire from simple broadband-pulsed ‘grunts’ that later differentiate into four distinct vocalizations, including low-frequency amplitude-modulated ‘boatwhistles’. Whereas fry emitted mostly single grunts, large juveniles exhibited vocalizations similar to the adult vocal repertoire. Moreover, we showed that the number of stereotyped vocalizations increased in large juveniles above 5 cm SL, which was coincident with an increase in saccular auditory sensitivity. Saccular sensitivity revealed a three-fold enhancement at most frequencies tested from small to large juveniles; and large juveniles were similar in sensitivity to adults.

This study provides first clear evidence of ontogenetic development of the vocal repertoire in fish, as previously described for higher vertebrates. The results suggest a parallel development between the vocal motor pathway and the peripheral auditory system in fish. We suggest that this parallel development may serve an important and conserved function in the development of social acoustic communication among vertebrates.

Public lecture: On a windy day lets go flying

On a windy day lets go flying

Dr. Miguel Repas
(Intern. EIA consultant and Exec. Dir. of STRIX)

About the Talk

The energy sector is a key component and driver of economic development requiring a large amount of infrastructure, both to generate the electricity and to transmit it through electrical power lines. These important developments are sometimes planned for sensitive locations within important flyways. Wind energy is considered to be a clean energy source but it produces negative impacts regarding avian mortality in these energy facilities.

The potential impacts are likely to be related to risks resulting in death or injury, barrier and disturbance effects for migrating species and soaring birds which can affect both their condition and behavior and result in disturbance along the migratory route. These risks can be minimised if appropriate actions and mitigation procedures are integrated into the energy project.

BSJ 50MW Wind Farm (SW Portugal) is within a migratory flyway of international importance, being crossed by more than 5000 individual birds of over 30 different soaring bird species every autumn. The wind farm’s licensing was conditioned to the implementation of thorough bird mortality mitigation procedures including temporary curtailment of wind turbines in order to reduce the probability of bird casualties from collisions.

Radar Assisted Shutdown on Demand (RASOD) protocol, is a wind farm security perimeter with observers aided by a radar detected soaring birds approaching the wind farm, whose turbines were to be turned-off when pre-defined criteria of intense migration or presence of threatened species were met. RASOD may be an essential tool in reconciling wind energy production with the conservation of soaring birds in areas where such a conflict may emerge.

Public lecture: The 2014-15 volcanic eruption on the Fogo Island in Cape Vert

The 2014-15 volcanic eruption on the Fogo Island in Cape Vert

Prof. João Mata
(GeoFCUL, IDL)

About the Talk

The Cape Verde Archipelago (eastern middle Atlantic) comprises 10 major islands (9 inhabited) and some islets with a volcanic origin and formed along a period of more than 26 millions of years. However, since its discovery in the 15th Century, volcanic activity has been observed only at Fogo Island, with written accounts of 27 eruptive events. The 3 last eruptions occurred in 1951, 1995 and 2014-2015, with the last one having been accompanied by the author, as member of a volcanological mission of the Universidade de Lisboa.

The emitted lavas during the 2014-15 eruption occupied an area of circa 4.7 km2, corresponding to an approximate volume of 4 x 107 m3, almost completely destroying the villages of Portela and Bangaeira, this one located at some 5 km from the volcanic vent.

Besides the description of the eruption and its consequences, the causes of the Cape Verde volcanism will be discussed. The “eminent” birthing of a new island will be also mentioned.

Public lecture: The effects of eutrophication on costal ecosystems

P. Cardoso
(Univ. of Coimbra)

ABOUT THE TALK

Coastal zones and shallow marine habitats are among the most productive ecosystems on Earth. In many locations, they are subject to a variety of anthropogenic stressors, such as pollution and eutrophication (organic enrichment). Over the last 30 years, loss of seagrasses and mangroves associated with eutrophication phenomena has become a worldwide problem. This talk explores the main causes of eutrophication, including the unbalance of the biogeochemical cycles of nitrogen and phosphorus, and focus on the effects of eutrophication on the structure (density/biomass, species diversity) and functioning (secondary production) of particular key species. In addition, mitigation and conservation measures will be explored.

Public lecture: Conservation and contamination of mangrove wetland

Conservation and contamination of mangrove wetland

Prof. Nora F-Y Tam
(Chair Prof. in the Dep. of Biology and Chemistry and Dir. of Futian-CityU Mangrove R&D at CUHK).

ABOUT THE TALK

Mangrove wetlands, one of the three coastal wetland ecosystems in the intertidal zone in tropical and subtropical regions, have important ecological and socioeconomic values. They are vital for healthy coastal ecosystems, and also provide prime nesting and migratory sites for birds and wildlife. In Hong Kong and South China, the contamination of toxic chemicals is a major threat to mangrove wetlands due to rapid urbanization and industrialization. Moderate to high concentrations of toxic contaminants have been detected in mangrove sediments. Mangrove plants also accumulate toxic contaminants, particularly in root tissues. The lecture will give details on the conservation of mangrove wetlands, the contamination problem and the tolerance of mangrove plants to toxic contaminants.
