Thank you to LES staff and students that contributed to the website.
Across the world, natural ecosystems are becoming increasingly degraded and fragmented. As a consequence, preservation of remaining intact habitats is likely to be insufficient for many species. Instead, the United Nations has identified restoring wild places as a global priority in its upcoming decade on ecosystem restoration.
In response to this, former Bournemouth Life and Environmental Sciences alumnus, Lindsay Biermann, has helped found the Little Environmental Action Foundation (LEAF for short) alongside thirteen fellow young conservationists. LEAF’s mission is to restore some of the most threatened ecosystems across the tropics, whilst using research-driven approaches and 100% native species.
LEAF’s first project is focused on cultivating and planting indigenous trees in coastal Kenya. Situated in the East African Coastal Forest Biodiversity hotspot, this project aims to save the region’s endemic trees that are all predicted to go extinct by 2050 without intervening action. LEAF is working in partnership with Pwani University to recover seeds, grow seedlings and plant out these threatened endemic species around fragments of ancient forest sites called relics. These relics are incredibly important to the future of this region, as currently 96% of native trees have been lost to monoculture plantations and farming.
Using research and expertise, LEAF has begun by employing local graduates and implementing ex situ conservation on the university grounds. From here, we plan to expand our efforts to plant trees close to pre-existing relict sites, educate local people on how to protect these forests and show why their ecosystem services are invaluable. By focusing on native tree species, we aim to increase the survival rates of planted trees and also the long-term recovery of these forests. Collaborative research with university students is also helping to maximise survival rates by studying salt and drought tolerance, as well as optimal planting times.
LEAF is set to officially launch in National Tree week running from 28th November to 6th December. As part of the launch, LEAF is aiming to raise funds to build a new seedling nursery that can propagate and grow rare and endangered tree species. From these donations, LEAF hope to transform the nursery to provide sufficient capacity for future forest restoration projects.
The LEAF charity is remains in its infancy but has ambitious plans to expand its restoration work into ten countries by 2030. Potential projects in Rwanda and India have already been identified, whilst a UK-based school outreach programme is being developed.

Bacteria and Archaea, collectively known as prokaryotes, are the oldest forms of life on the planet, they’ve been around for over 3500 million years and are ubiquitous, meaning they are found all across the earth in every environment, some of which are adapted to living in extreme environments such as hot springs, hydrothermal vents and glacial environments.
Although some bacteria cause a variety of diseases in plants and animals, including humans, bacteria and archaea are key for a variety of environmental processes, including aquatic photosynthesis by cyanobacteria and nutrient cycling in terrestrial and aquatic environments. As well as this, some prokaryotes form key partnerships with animals and plants, such as nitrogen fixing species in plant roots and gut bacteria which help break down food.
For these reasons, studying bacteria and archaea is particularly important, to understand their use in medicine and combatting disease, their role in the environment and potential to buffer habitat against environmental change, and their importance in biotechnology. Bacteria and archaea are notoriously difficult to study in the lab, as their tiny size and immense diversity in metabolism and optimal requirements make it difficult to culture them. As a result of this, researchers have turned to genome sequencing as a way of studying these organisms.
Collaboration between researchers across the world has led to the ‘Genomes from the Earth’s Microbiomes (GEM) catalogue’, a database which contains over 52, 000 draft genomes, encompassing a large spread of samples collected from all across the world, including agricultural and natural soils, oceanic and freshwater samples, and sample collected from associated human/animal hosts and symbiotes.
The GEM catalogue has been possible despite the difficulty of bacterial culturing due to a revolutionary technique known as metagenomics. Essentially, organisms leave traces of DNA in their environment, such as lakes, soils, etc., which can be picked up in sampling, meaning that growing the species in the lab is not required to study it’s molecular biology. Through this, samples are sequenced and the DNA of various organisms can be detected, which also gives an idea of the biodiversity of the habitat.
The development of the GEM catalogue has provided researchers with an invaluable resource for studying bacteria, from their ecology, molecular genetics to help tackle disease and understand more about their place in the environment. The database has also shown that these microbes are far more diverse and numerous then we once thought, providing a wealth of information for researchers .
A new species of pterosaur about the size of a Turkey has been discovered by UK researchers. About 110 million years old, this strange finding is key to understanding the true diversity of these ancient winged reptiles.
Discovered in Morocco, North Africa, the remains belonged to a small winged reptile, or pterosaur, called Leptostomia bagaaensis which lived during the middle cretaceous period, between 94 and 113 million years ago. The fossil consists of a pair of long, toothless and flattened jaws, which bear resemblance to the beak of a curlew, a type of wading bird common on British coastline.
Although it is a common beak shape in birds, it was previously unheard of in pterosaurs, and originally was not thought to belong to a pterosaur at all. When researchers at the universities of Bath and Portsmouth analysed the mandibles, CT scanning revealed a network of internal canals – surface compressions across the surface of the beak – similar to those found in wading birds such as curlews and sand pipers. This made the beak highly sensitive to touch and it is very likely that this pterosaur could use its beak to detect prey.
Despite being a desert environment now, the Kem Kem formation of Morocco, where the specimen was found, would have been a rich habitat in the mid cretaceous period, consisting of rivers and estuaries. So this pterosaur, attracted to the area by the rich source of prey, would likely flock in large numbers, sifting through the water and probing for prey such as aquatic insects.
This is a really exciting find for researchers because it has revealed new feeding behaviours previously unknown in pterosaurs, further unearthing the diversity of these reptiles.
Dorset wildlife trust has recently introduced a colony of black bees into the DWT Kingcombe in West Dorset. The aim of this project is to establish a successful regional population in the area and to study foraging habits and pollen preferences in the colony, to better understand these bees’ behavioural patterns. The colony was extracted from an already established and successful colony in South Wales, and introduced to the Kingcombe centre orchard.
Also known outside of the UK as the dark European honey bee (Apis mellifera mellifera), the black bee is a subspecies of the European honey bee (A. mellifera). UK populations of the black bee were thought to be extinct by the 19th century, mainly due to a proliferation of tracheal mites, tiny parasites which infect and reproduce in the breathing tubes of the bees, however small isolated populations were found in Wales and Scotland back in 2012.
Considered as the ‘native’ honeybee, the black bee is perfectly adapted to the colder climate of the UK, able to fly and survive in colder temperatures, considerably larger than the continental honeybees, and with longer hairs on the thorax. It is also thought that these bees are more resistant to some diseases, such as bacterial and amoebic infections.
It is hoped that the establishment of this colony will not only help to increase local pollinator diversity, contributing to local ecosystems by boosting pollination, but also prevents an exciting opportunity to understand more about the bees’ behaviour in order to conserve them and increase local biodiversity.
A curious little mammal, a species of elephant shrew, has been rediscovered after being absent from scientific observation for 50 years. Despite some local sightings, the animal had been ‘missing’ from scientific records since the 1970s. It has now been seen again in the African nation of Djibouti. Previously known only from Somalia, the Somali Sengi, or elephant shrew is one of the most mysterious species of sengi, with only 39 specimens previously known to science.
The elephant shrew looks very much like a mouse, with a small furry body and long tail, and so named for its long, trunk-like proboscis, which they use to feed on insects. However, these curious little mammals are in fact part of a group called Afrotheres, which means they are more closely related to Elephants, Manatees and Dugongs, than to mice.
In the current environment where species are being lost at an alarming rate, this discovery is a highly important and positive one. The discovery proved puzzling to scientists, because as the name suggests, the Somali sengi was originally only known from Somalia. The next planned expedition will be to track these animals using GPS radio tracking to learn more about their movements and behaviour.
A new species of carnivorous dinosaur has been discovered from fossilised remains found by members of the public at Shanklin, Isle of Wight last year. The four bones were examined by researchers at the University of Southampton who believe they belong to a new species of theropod dinosaur (a group of carnivorous which also include modern birds and their famous Tyrannosaurus rex).
The dinosaur has been named Vectaerovenator inopinatus which means ‘unexpected air-filled hunter’. The name refers to the curious air-filled sacs in many of the bones of the creature, in the neck, back and tail. Indeed, these structures are also found in many other theropod dinosaurs, helping scientists to identify it.
These air sacs, which act as extensions of the lungs, are also found in modern birds, which not only make the skeletons much lighter, but also ensure much more efficient breathing.
Living around 115 million years ago during the cretaceous period, Vectaerovenator was around 4 metres long, a relatively small size for Dinosaurs of this group, and although likely it would not have been the top predator, it would certainly have been an efficient carnivore, probably feeding on reptiles and small, herbivorous dinosaurs such as Hypsilophodon which was a common species at the time.
This exciting find is another example of how our understanding of prehistoric biodiversity is constantly changing with the discovery of many new prehistoric species.
Largely invisible and often overseen, fungi and other microscopic organisms are highly abundant in soils across the world, and play a fundamental in maintaining the biodiversity and nutrient balances in their ecosystem.
Fungi, although visible in the form of fruiting bodies, or toadstools, during certain times, are largely invisible, existing as microbial threads in the soil. It is estimated that there are some 3.8 million species of fungi, only a fraction of which have been formally described and identified. These organisms are incredibly abundant in soils around the world, an are a key component of biological nutrient cycling, as they break down organic matter, releasing key nutrients and compounds from dead bodies. Fungi are found in a variety of areas such as rainforest, woodland, grasslands and even rocky substrates (in the form of lichens) but are most abundant in open areas such as grasslands and Savannah, where they are important in helping poorer soil uptake nutrients.
In the Amazon rainforest for example, fungi are surprisingly abundant and varied. For example, a teaspoon of rainforest soil is estimated to contain around 1800 species of microscopic organisms (according to a study carried out by Dr Camila Duarte of Germany), at least 400 of which are fungi. These fungi are so diverse and they occupy a variety of niches in the forest, such as lichen (a symbiotic relationship between fungi and microscopic plants), some living commensally in the roots of plants and some as plant pathogens and parasites. Each and every one of these plays a significant role on the forest floor, breaking down organic matter and releasing nutrients back into the soil, to be used by plants and animals.
In this sense, the sheer diversity of fungi in the soil means that it is essential to consider this hidden diversity in conservation efforts, particularly in such fragile ecosystems as the Amazon rainforests. Due to their inconspicuous nature fungi are often overlooked in biological surveys, but they are key for nutrient cycling and also act as carbon sinks, absorbing carbon dioxide from dead organisms.
Some species are also edible, and are a source of medicine, indeed fungal compounds are being considered as new antibiotic sources in the light of antibiotic resistance. On the other hand, some fungi are considerable pests to crops, while others are disease-causing pathogens which cause disease in humans and animals. There is much to learn about soil fungal diversity, in order to incorporate these organisms into conservation efforts, and to help maintain biodiversity.
