How extreme heat events are impacting Indian flying foxes in Pakistan: Touseef’s work broadcasted on DW News

The effects of climate change have led to an increase in extreme heat events, causing mass deaths among fruit bats of the genus Pteropus in various parts of the world. The Indian flying fox (Pteropus medius) is facing a shrinking habitat, and its distribution has shifted from southern to central and northern regions in Pakistan to escape rising temperatures and heat events. This DW News documentary covered our research work on “Effect of Extreme Heat on Indian flying foxes in Pakistan“.

Touseef Presents Poster on Future Directions for One Health Research at 7th World One Health Congress 2022 in Singapore

Touseef posed in front of his poster titled “Future directions for One Health Research; Regional and Sectoral Gaps

A competitive Travel Award by the Congress Organizing Committee enabled Touseef to attend the 7th World One Health Congress in Singapore to present his research “Future directions for One Health Research: Regional and Sectoral Gaps”. The concept of One Health highlights the important inter-relationships between health and well-being of people, animals, plants, and the environment which supports their existence. However, implementation of a One Health approach varies considerably between different geographical regions and remains challenging to implement without greater inclusivity of different disciplinary capacity and expertise. Identifying regional and sectoral gaps will help achieve One Health research parity.

Bangladesh Has at Least 31 Bat Species! – Ashraf’s first PhD paper is out

Bat research is limited in Bangladesh, so to date estimates of bat diversity in the country have been based on a few ad hoc studies and expert opinion.  To gain a more complete understanding, Ashraf compiled species occurrence data from the literature, museum records and the Global Biodiversity Information Framework (GBIF). He set out to confirm species presence and identify species that might be expected to occur in Bangladesh based on occurrence records in neighboring countries and habitat preferences. To visualize the distribution of bats, Ashraf made maps for each species recorded from Bangladesh and species that might occur in the country.

He found a total of 31 species are recorded for Bangladesh – but only 22 are associated with voucher records. Evidence for nine species came from photographs and/or human observation. An additional 81 species were recorded from surrounding countries. Of these, 38 species are highly likely to occur in Bangladesh.

So what is next? To expand the country list, Ashraf recommended that surveys of bats in Protected Areas, caves and wetlands be prioritized. Surveys should use multiple methods, including contemporary techniques (harp traps and acoustics) that have not been used in Bangladesh before, as well as traditional ones (mist nets). He emphasized that voucher specimen collections are needed to confirm the presence of and distribution of bats in Bangladesh and identify areas central to bat conservation.

Ashraf just finished his long waited first season of fieldwork this Summer 2022 in Bangladesh. The field season started with a Seminar as Dr. Tigga Kingston was invited to speak at the Jagannath University, Dhaka, Bangladesh as keynote speaker. Dr. Kingston’s talk was entitled “Diversity and Conservation of Bats in Paleotropics”. A further talk was given by Ashraf on the human dimension of bats and current bat research in Bangladesh, and the project “Bats of Bangladesh: Bat Assemblage Structure and Species Responses to Land-use Change” he was undertaking. Later, Dr. Kingston visited Ashraf’s field site to see if the study design was feasible and build bat research capacity. As part of the capacity building, Ashraf, and his team (4 students) received hands-on training on complementary field methods such as harp traps, mist nets, and acoustics to capture and record bats. They also got training on collecting morphometric data of bats and taxonomy.

In this season, Ashraf worked in three protected areas of Bangladesh. He and his team caught ~550 bats and ~17 species!  The project was funded by the Rufford Foundation, Bat Conservation International, Michelle C. Knapp Memorial Scholarship, and obviously, the equipment support was provided by the Kingston Lab.

The Kingston Lab at IBRC 2022 and the first ever GBatNet research meeting

The first weeks of August were a busy time for the lab. First, we helped plan and run the first ever Global Union of Bat Diversity Networks (GBatNet) in-person research meeting. Held in Austin, TX, USA, this meeting brought together 67 researchers from 25 countries and research areas ranging from applied conservation to genomics to disease and many more! Together, we identified 15 interdisciplinary and multidisciplinary research projects that will forward GBatNet’s mission to understand and protect bat diversity in a changing world.

We then ran across town to co-hoast the 19th International Bat Research Conference. In addition to helping run the conference, Tigga presented her talk on GBatNet’s history and mission, Abby her talk “Bat Meat: Preference or Necessity? The Role of Protein
Limitation in Driving Bat-Hunting”, and Adrienne her’s entitled “A Seasonal Comparison of Foraging Movements of Pteropus alecto From an Urban and Peri-urban Roost”. Touseef presented his poster “The Role of Heat Stressed Indian Flying Foxes in Propagation of Antimicrobial Resistance in the Environment”, and recent Texas Tech undergraduate Elaine Tackett gave her first in-person poster “Global Medicinal Use of Bats: A Systematic Literature and Social Media Review“. As if that wasn’t enough, everyone contributed to running the GBatNet’s Wednesday research and recruitment workshop, attended by over 150 people.

In addition, Kingston Lab alums were well represented throughout the conference. Recent graduate Iroro Tanshi gave an early career plenary on ” Harnessing Local Capacity to Uncover and Protect Hidden Afrotropical Bat Diversity, Nurul Ain Elias and Kendra Phelps both co-chaired sessions and presented talks, and Juliana Senawi presented her work “The Distribution and Conservation of Island Bats in Langkawi Archipelago of Malaysia.”

It was an exhausting and exhilarating time filled with old friends and new ideas.

Baobabs and bats – new publication on the influence of the landscape and plant traits on fruiting success

Baobab (Adansonia digitata) trees are iconic symbols of the arid lands of continental Africa, and aside from some populations in Southern Africa are largely dependent on fruit bats for pollination. However, the bats visit a diversity of plant species to meet their energetic and nutritional needs, so the pollination service they provide the baobabs may be influenced by the landscape context of individual trees. In collaboration with Dr Paul Webala, Macy Krishnamoorthy set out to determine the relative contribution of individual plant traits, namely tree height and girth, and landscape features and context (e.g., the distance of baobab trees to conspecifics, distances to resources that might attract or distract bats, land use) to baobab reproductive success. Very ably assisted by Mr Michael Bartonjo, she mapped more than 700 baobab trees in ~10 km2 area in Kenya, measured them, and derived a number of landscape variables for each tree. She counted the number of fruit per baobab as a measure of reproductive success.

So what did she find? Perhaps not surprisingly, larger trees were more likely to produce fruit and produce more fruit, but landscape variables also played a role, but in a complex and scale-dependent way. The importance of distance to and density of alternate food resources changed with scale, but generally, pawpaws tended to act as attractants whereas figs distracted bats from their role as pollinators.

Fieldwork was fun but arduous and there are many people in Kenya to thank! A special thank you to Macy’s local host Daniel Ngei and his family, the local chief Joseph Kavui and all the landowners in the villages of Kaai, Kalesi, Kaluku South, Kandundu, Katithini, Kavui, Kawula, Kiwaani, Mutoleka, Ngieni East, Ngieni West and Yungamaduu who generously allowed us to sample baobabs or others fruiting trees on their lands. Funding for the project came from Bat Conservation Internationa, the Association of Biologists at Texas Tech University, and the Department of Biological Sciences at TTU.

Bats love the baobab flowers, but the fruits are quite a local snack for people. Here they have been dyed green to be sold for $0.05 a bag.

Another New Publication!

Tigga, Abby, and Elaine are authors in “Global Medicinal Use of Bats: A Systematic Literature and Social Media Review” that was published in Diversity. This paper quantifies the various uses of bats, such as for food or medicine, around the world by their IUCN regions. It was determined that, “Consumption for food was prevalent in regions of Asia, Africa, and Oceania, whereas medicinal use was most commonly reported in South Asia (where it exceeded consumption for food), Southeast Asia, and to a lesser extent, Africa and South America.” The paper also quantifies the various aliments that are treated with bats.
