The second international workshop on Orthoptera bioacoustics in Europe (TEOSS project) took place in Sierra de La Demanda in Spain, from 7 to 16 August. The meeting of more than 30 orthopterists was important for the future of Orthoptera studies in Spain. It allowed for learning a lot of new information, sharing experiences and trigering the enthousiasm and interest for grasshoppers, crickets and bush-crickets.

The first morning was hosted in sala municipal de Monterrubio. Florent Prunier (AEABA) intoduced the assistants to TETTRIS, TEOSS project and the different topics covered by the training. The group seems genuinely enthusiastic about participating to the workshop.

The lecture Introducción a los cantos de ortópteros by the Spanish expert Rafael Carbonell covered the basics of sounds and sound study, and was followed by practical exercices and study cases using software. Rafael generously offered a very useful library of sound files covering common species in Cataluña.

Activity 2 : Working flow for the workshop

Baudewijn Odé, member of IUCN Orthoptera group, presented TEOSS methodology and the steps for recording Orthoptera’s sounds, from the field to the lab. In this project, data will be collected in Xeno-canto webpage. The detailled steps of the field protocole were studied with the participants. Later, Cécile Malige, a student doing practice in AEABA, presented the different recording devices used in the course and gave instructions.

SECOND DAY

Activity 1 : Field trip at mid-altitude

Teh group reached Puerto del Manquillo at 10:00 and explore a range of grasslands, forests and shrubland in altitude ranging from 1.400 to 1.600 masl. The day was very hot and sunny.

We also visited North facing slopes at Valle del Sol (1.400-1.500 masl).

Activity 2 : Lab work, discovering how to upload data…

The group was hosted in the office of Agalsa Sierra de la Demanda, in the gorgeous village of Pineda de la Sierra.

For the first time, the participants started uploading the data and files collected in the morning. Much has to be learnt… CX, Observations, trimming files and of course putting a correct name on the pictures and sounds. Quite an intense session.

Activity 3 : More basic talks

Baudewijn presented the different types of microphones he is using to study sound productions of Orthoptera (e.g. ultrasonic, professional, omnidirectional).

The second part of the field guide (crickets and bush-crickets) was also explored.

Activity 4 : Nocturnal field work

Ensifera are very active during the night and it is often the best time of the day to record their song. The group explored Hoya Ranas / Llanos de La Lastra with great succes. Among the many species recorded, observing Eugryllodes pipiens (photo Julien Barataud) singing was one of the workshop highlight.

THIRD DAY

Activity 1 : Fieldwork at hight altitude

The nature reserve of Lagunas de Neila offers an extraordinary variety of high altitude ecosystems, with deep water lakes, boggy streams, grasslands, pine forest and high altitude scrublands and stony substrates. The trip was the most beautiful of the workshop with some nice addition in the species list. We listen and looked hard for the elusive Callicrania. This very long session allow for every participant to test all devices and record both Caelifera and Ensifera.

Activity 2 : Lab work in Barbadillo

The backlog of records started to build up… and it became necessary to spend more time in the lab. We have difficulties with internet connection since the course is hosted in a village with low signal. After a session of Q&A, the group starts to gain its autonomy in managing the work flow.

Activity 3 : Conference and advices

Filippo Buzzetti, from Fondazione Museo Civico di Rovereto, gave a talk on sound production in Orthoptera, comparing the different anatomical features that allow the insects to sing. Recommended softwares are SeaPro and Cool Edit for sound treatment. Recording at home (anemochoric cameras with automation to subdivide an entire night’s audio into small fragments).

FOURTH DAY

Activity 1 : Orthoptera of the lowlands

The first locality visited the grassy and lush sides of a streams near Hacinas in the lowland. A perfect locality to discover species restricted to wet vegetation.

Activity 2 : Extra field trip

Large river side and dry Juniper forest close to Hortigüela. The habitats were extremely dry and not much favourable to Orthoptera. The nicest recording was the courtship of Oedipoda males.

Activity 3 : Sharing experiences about taxonomy and bioacoustic

We were fortunate to count with the French Orthopterist Julien Barataud who shared with us his own experience with bioacoustics: the study of the variability of Barbitistes fischeri sound productions and the recent desciption of the new Iberian species Phaneroptera laticerca. Julien gave various exemples of songs produced by close relative species.

FIFTH DAY

Activity 1 : Conferences – Widening knowledge.

The last morning is hosted at Monterrubio again. We close the workshop with various conferences. XENO-CANTO GAPS IN ORTHOPTERA KNOWLEDGE – Baudewjin Odé; ORTHOPTEROIDEA (Florent Prunier); ECOLOGY & IMPORTANCE OF ORTHOPTERA FOR ECOSYSTEM VALIDATION (Ginés Rodríguez).

It was soon time to make a group picture and plan to see each other next year !

SECOND SHIFT

Of course, the second team was no less important than the first shift. Having said that, we repeated the contents and visited the same localities. This session was also shorter with three full days dedicated to TEOSS. It seems not too important to repeat the schedule here. The group was smaller with seven participants and it was easier and quicker to explain all the concepts covered by the workshop. Of course, Marta and Florent were better trained as teachers too (!). We spent three full days in the lab and the field.

In this occasion, we were fortunate to count, among the participants, with the presence of David Funosas, pHd at Université de Caen, with an on-going thesis on Orthoptera and bioacoustics.

For the first fieldtrip of the workshop we didn’t go far: we visited the Adige Sud Park, a river flood plain of almost 2 million square meters inside the city of Verona. It includes the area of the Adige river in the northern and southern sections of Verona, which are linked by itineraries running along the river from the dam of Chievo to the areas of Boschetto, Giarol Grande, and Bosco Buri. In 2005 it was characterised as «a protected area of local interest» on a municipal and state estate. Here, we found 20 Orthopteran species. It was great to see such a high diversity of orthopterans inside a city park!

[/et_pb_text][et_pb_text _builder_version=»4.25.1″ _module_preset=»default» global_colors_info=»{}»]

Our second visit was the hill of Monte Tenda above Soave Castle. It is a beautiful xerothermic hill characterised by a cypress forest (Cupressus sempervirens) and shrubby vegetation. Other trees like the European nettle tree (Celtis australis), maple (Acer sp.), and the manna ash (Fraxinus ornus) also occur there, but most importantly we found there 18 Orthopteran species. There were also hundreds of cicadas screaming constantly and relentlessly, which presented a big challenge for getting good sound recordings for the Orthopterans; but we pulled through! Most common Orthopteran sounds in the area were the songs of Decticus albifrons and Platycleis grisea. Our fieldtrip ended in a local winery, were we tasted a wonderful white wine. It was most refreshing in that hot summer day!

Species only in this locality: Anacridium aegyptium, Calliptamus siciliae, Oedipoda caerulescens.

The same night we visited another area of the Adige Sud Park in Verona, a part of the park including mostly fields and abandoned fields, as well as a more forested area, in order to collect nocturnal sound recordings. Here, we found a total of 22 orthopteran species. In the quietness of night and without the cicada songs that were drowning all sounds during the day, we managed to record and identify more orthopteran species than in the previous excursions. Most impressive species was Ruspolia nitindula, a bush-cricket whose song is extremely loud, especially when you draw too close, sounding like a deafening electric discharge.

Species only in this locality: Eumodicogryllus bordigalensis, Oecanthus pellucens.

Also in present loc 4: Yersinella raymondi, Tetrix tenuicornis.

Pachytrachis striolatus (S. Koenig).

[/et_pb_text][et_pb_text _builder_version=»4.25.1″ _module_preset=»default» global_colors_info=»{}»]

The next day we visited the Parco della Biodiversità in Fumane. It consists of a mixed landscape, including karst valleys, forests and wet areas around two artificial lakes, as well as arid meadows. The park hosts numerous animal and plant species included in the Annexes of the Habitats Directive which are worthy of protection. This variety of habitats was reflected to the number of Orthopteran species we found: 28, the most we have detected in a single locality. Standout finding was the beautiful Saw-tailed Bush-cricket Barbitistes serricauda, an arboreal bush-cricket.

Species only in this locality: Barbitistes serricauda, Barbitistes vicetinus, Poecilimon elegans, Meconema meridionale, Pholidoptera fallax, Pachytrachis striolatus, Paratettix meridionalis, Sphingonotus caerulans.

Also in present loc 5: Pholidoptera aptera.

Poecilimon ornatus (S. Koenig).

[/et_pb_text][et_pb_text _builder_version=»4.25.1″ _module_preset=»default» global_colors_info=»{}»]

Our last fieldtrip brought us to the alpine meadows and pastures at the ski center of Bosco Chiesanuova, following the road from San Giorgio, a ski school, to Conca dei Parpari. In an altitude of 1600m, we enjoyed a walk through the beautiful meadows of the Alps, always with our recording devices in hand. The most prevalent by far sound we recorded was the soft Gryllus campestris song, but the short trill of Poecilimon ornatus was also common in the more humid areas with green bushes. This was the poorest locality regarding the number of species, with only 14 species found between all participants.

Species only in this locality: Poecilimon ornatus, Tettigonia cantans, Decticus verrucivorus, Tetrix bipunctata, Omocestus rufipes, Omocestus viridulus, Stenobothrus lineatus.

Florent Prunier has presented the talk Training for building a European Orthoptera sound database in front of the audience of European orthopterists, highlighting the project’s efforts to develop a comprehensive sound database for European orthoptera species. The Book of abstracts of the conference is available at the Fondazione Museo Civico di Rovereto’s website.

The following two talks were also dedicated to bioaccoustic and were presented by trainers participating in TEOSS project. Francisco Rivas Funzalida presented his Rthoptera, a New Open-source Software for Standardized Insect Bioacoustics and Baudewijn Odé the Recent progress in sharing sound recordings worldwide: Orthoptera in Xeno Canto.

David Bennett, a participant in the subsequent Verona training camp, presented on the Relative performance of passive acoustic monitoring with Audiomoth compared to traditional transect methods, and construction of an automatic machine learning classifier for Orthoptera in Schleswig Holstein, Germany.

The TEOSS project’s participation in ECOC IV was successful, facilitating connections among researchers through various communications on related themes. It also provided an opportunity to present results and tools useful for the European community of Orthoptera recordists

This project has funded by TETTRIs Consortium (*) and is led by non TETTRIS members in what is called Third-Party Projects. More precisely TEOSS responds to Topic 4. The co-development of AI-based sound recognition of European grasshoppers. In summary, The projects should help to showcase that training professional and non-professional taxonomists in collecting sound recordings can help improve the model.

(*) The Horizon Europe Project Transforming European Taxonomy through Training, Research and Innovation (TETTRIs) is a joint effort of 17 partners tackling the shortage of taxonomic experts and resources in tools, training, and access to funding. As an EU funded project TETTRIs is co-led by RBINS and CETAF (acting as main contact point for 3PP Call). TETTRIs aims to enhance the understanding of the diversity of life on Earth through research, training, and innovation in taxonomy, particularly in European biodiversity hotspots and protected areas.

1- We will organize four international workshops, one in each European Mediterranean peninsula. Training includes a practical syllabus for recording high quality Orthoptera sounds and intensive field work for collecting numerous samples.

2- Expert taxonomists will identify individuals with collected sounds, a most critical step for
establishing reference collection. Raw data will be published in online biodiversity platforms and remain widely available.

3- We will feed EOSS with public libraries and update its taxonomic coverage. Activity of trainees and new members of EOSS community will be triggered through social media and scientific meetings, such as the European Congress on Orthoptera Conservation.

4- Machine learning (AI) will be further trained on TEOSS in collaboration with the TETTRIs consultants.

Location: Mediterranean Basin biodiversity hotspot (Myers, 2000). European Mediterranean peninsulas (Iberia, Italian, Balkans): Spain, Italy, Greece. Alpine region (Northern Italy). Those areas are especially important for arthropod biodiversity in general and especially for Orthoptera (Kenyeres et al., 2009).

Spain: Andalusia. Workshop organized in the Genal Field Station, a NGO biodiversity center located in the Genal Valley, surrounded by Strait of Gibraltar NP, Los Alcornocales NP, Grazalema NP, Sierra de Las Nieves NP, Sierra Bermeja. More than 100 species, numerous West Mediterranean endemics, especially rich for Ensifera.

Italy: The workshop will be organized in Verona (Northern Italy) by WBA Project srl. The event will coincide with the fourth European Congress on Orthoptera Conservation and field work will explore the Alpine and Mediterranean areas.

Greece: The venue will be in the Epirus region, e.g. in the heart of N Pindos National Park and Vikos-Aoos Unesco Global Geopark, boosting a rich Orthoptera fauna.

Objectives of the project

It is estimated that 1,082 Orthoptera species are native to Europe (European Red List, 2016).

Mediterranean peninsulas (Iberia, Italian, Balkans) and Alpine region are identified as biodiversity hotspot for Orthoptera in Europe (Kenyeres et al., 2009).

Among insects, Grasshoppers, Crickets and Bush-crickets are notorious for the use of stridulation and sound production in communication and reproductive behaviour.

In some cases, sister species are better identified by their sounds than by their external morphology (e.g. Chorthippus biguttulus-brunneus-mollis group).

From this background, we can conclude that:

A) Identification by sound recognition only is possible for trained experts, but still very limited among enthusiasts. Orthoptera citizen science schemes would benefit from algorithms suggesting identification.

B) Bioacoustics is a major tool for taxonomical research and for the detection of new Orthoptera species in Europe.

[/et_pb_text][et_pb_text _builder_version=»4.16″ _module_preset=»default» global_colors_info=»{}»]

The quality and geographical coverage of the algorithm largely depends on the availability of training data. Typically a loop of positive feedback establishes : recorders can help improve the model with their participation, then more training data becomes available, which in turn improves an updated version of the model, resulting in more interested users. Our approach is to focus on the capacity of recorders to provide samples to trigger this loop.
– The courses will be addressed to professional and non-professional taxonomists, which have already experience with Orthoptera.
– The teaching will focus on collecting sound recordings to build the capacity of sound recording in 2024 and 2025.
– The training will be the most practical and include sound-based identification of grasshoppers and collection of sound data using open access websites (xeno-canto.org, observation.org and other existing platforms ready to collaborate with export of their records).

TEOSS consortium is a gathering of entities active in the study and the dissemination of Orthoptera diversity, nearly all of them based in the Mediterranean area and more precisely in each of the European peninsulas within the Mediterranean region. The consortium offers a variety of complementary fields of actions within the Natural Sciences.

It must be noted that an international workshop on Orthoptera identification, including sound recognition, was held in July 2023 in Konitsa (Greece), organized by one of the project’s partners (University of Ioannina), with the participation of trainers specialized in bioacoustics (Baudewijn Odé) which are part of this project. The partners are already linked together through their participation in the European Congress of Orthoptera Conservation and the connection with the IUCN Grasshopper Specialist Group involved in the European Red List of Orthoptera.

Workshop organized in the Genal Field Station, a NGO biodiversity center located in the Genal Valley, surrounded by Strait of Gibraltar NP, Los Alcornocales NP, Grazalema NP, Sierra de Las Nieves NP, Sierra Bermeja. More than 100 species, numerous West Mediterranean endemics, especially rich for Ensifera.

Italy: The workshop will be organized in Verona (Northern Italy) by WBA Project srl. The event will coincide with the fourth European Congress on Orthoptera Conservation and field work will explore the Alpine and Mediterranean areas.

Greece: The venue will be in the Epirus region, e.g. in the heart of N Pindos National Park and Vikos-Aoos Unesco Global Geopark, boosting a rich Orthoptera fauna.

Objectives of the project

It is estimated that 1,082 Orthoptera species are native to Europe (European Red List, 2016).

Mediterranean peninsulas (Iberia, Italian, Balkans) and Alpine region are identified as biodiversity hotspot for Orthoptera in Europe (Kenyeres et al., 2009).

Among insects, Grasshoppers, Crickets and Bush-crickets are notorious for the use of stridulation and sound production in communication and reproductive behaviour.

In some cases, sister species are better identified by their sounds than by their external morphology (e.g. Chorthippus biguttulus-brunneus-mollis group).

From this background, we can conclude that:

B) Bioacoustics is a major tool for taxonomical research and for the detection of new Orthoptera species in Europe.

Improving Orthoptera recognition in Europe based on sound recordings and colaborative science.
