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.

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.
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.
A fossil recently discovered on the Isle of Wight has been revealed as a first of its kind to be found in the UK. The fossil belonged to an ancient flying reptile which would have soared through the skies of southern England 100 million years ago.
The fossilised jaw fragment was found by an amateur fossil hunter on Sandown beach, Isle of Wight. The delicate fossil was identified as a tapejarid (a type of medium-sized crested pterosaur) by scientists at the university of Portsmouth, recognisable by the characteristic shape of the jaw and minute holes in the jaw, which experts think were used to detect prey. The fossil has been donated to the IoW dinosaur museum for future display.
So, what did this animal look like? These pterosaurs were small to medium sized and lived around 100 million years ago, during the cretaceous period. With more curved wings than other species, they are well known for the large bony crests on their heads. It is very likely that these crests would have been highly colourful in real life, almost twice the size of the skull, and probably used to communicate and attract partners, much like many bird species such as pheasants and birds of paradise. There has been much debate concerning the diet of these animals, but it is thought that they fed on plant material, especially considering that flowering plants were diversifying around the time these creatures appeared.
The fossil is a key finding for our understanding of these creatures; before the discovery of this specimen, the tapejarids were only known from Brazil, Morocco and China, and this find not only demonstrates a very wide distribution of these pterosaurs, but also showcases the diversity of mesozoic species on the island and surrounding area.
Antarctica is arguably one of the most barren, extreme environments on the planet, with only one permanent terrestrial resident – the Emperor penguin. However, wind the clock back 90 million years, and the continent was far from a frozen wasteland. New evidence has suggested that this icy continent was largely covered in tropical swamp forest, during the time of the Dinosaurs.
The cretaceous period, which spanned from approximately 145 to 66 million years ago, was a very warm period in earth’s history, with an almost worldwide greenhouse climate, and an abundance of vegetation and tropical forests. Antarctica at this time was mostly covered in a swampy, tropical forest and there were no glaciers at the south pole.
Scientists at the Alfred Wegener institute, Germany, made this discovery by analysing sediment cores drilled from the seafloor in West Antarctica. These cores show a glimpse of the past environment in Antarctica, with sediments nearer to the bottom of the core representing older geological time. At three metres down on the core, representing the late cretaceous period, the sediment composition changed drastically, composed mainly of a coal-like material, soil, roots and pollen. The team identified over 65 types of plant material, indicating the presence of an ancient conifer forest.
So, what exactly lived in these forests? The forests would have likely been very similar in plant structure to some of the forests in modern-day New Zealand, dominated by towering tree ferns, cycads and coniferous trees. At this time in history, flowering plants had only recently evolved so were likely rare in these forests. Biogeochemical evidence from the sediment cores also revealed that microscopic photosynthetic life such as algae and cyanobacteria were common in warm lakes and rivers.
These forests were dominated by a variety of dinosaur species, which filled many of the ecological roles of forest ecosystems today. There were giant herbivorous dinosaurs such as the long necked Austrosaurus, and Muttaburrasaurus, a close relative of the Iguanadon, whose remains are commonly found on the Isle of Wight. There were also carnivorous dinosaurs such as Cryolophosaurus and Australovenator, and the tiny herbivorous Leaellynasaura, which likely lived in small groups in the forest. Primitive mammals shared the forests with the dinosaurs; they were furry, egg laying species which were likely similar to modern echidnas and platypus. It is also known that the river networks around these forests were home to a giant salamander-like amphibian called Koolasuchus, belonging to an ancient lineage of animals over 250 million years old.
The discovery of these polar forests is not only an exciting advance for palaeontology, but also shows us how key carbon dioxide levels are in the shaping of an environment. It is known that the tropical climate during the cretaceous period could have only been possible if carbon dioxide levels were much higher than today, so this discovery could give an insight into the future environmental implications of increased carbon dioxide levels in the near future.
