Relationship Between Endemic and Invasive Frogs on Grenada. [PDF]

Ecol Evol
The endemic Grenada frog (Pristimantis euphronides) is found only in high elevation cloud forests, habitat that is being invaded by the introduced Lesser Antillean frog (Eleutherodactylus johnstonei) and threatened by climate change. Between 2004 and 2020, our field team surveyed three key sites in the central highlands of Grenada to monitor ...

Ecological fitting is a sufficient driver of tight interactions between sunbirds and ornithophilous plants [PDF]

Ecology and Evolution, 2020
Plant–bird pollination interactions evolved independently on different continents. Specific adaptations can lead to their restriction when potential partners from distant evolutionary trajectories come into contact.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]

Conserv Biol
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Pest categorisation of <i>Pestalotiopsis microspora</i>. [PDF]

EFSA J, 2023
Abstract Following an EFSA commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) imported from China, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis microspora, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae.

Diversity and Activity Patterns of Medium-Sized and Large Terrestrial Mammals in Agroforests of a Peruvian Amazon Rainforest Region. [PDF]

Ecol Evol
We studied species richness and activity patterns of medium‐sized and large terrestrial mammals in agroforests located in the northern buffer zone of Tambopata National Reserve, Peru. The agroforests harboured a high number of mammal species, with species richness increasing alongside greater structural complexity of vegetation.

Susceptibility of Eucalyptus trees to defoliation by the Eucalyptus snout beetle, Gonipterus sp. n. 2, is enhanced by high foliar contents of 1,8‐cineole, oxalic acid and sucrose and low contents of palmitic and shikimic acid

Plant, Cell &Environment, Volume 46, Issue 11, Page 3481-3500, November 2023., 2023
Abstract Gonipterus sp. n. 2 (Coleoptera, Curculionidae) is an invasive, commercially important weevil that causes large‐scale defoliation of Eucalyptus trees. The weevil specifically feeds on young leaves and new shoots, thus reducing tree growth. The weevil displays a very strong preference for certain Eucalyptus genotypes, however, this behaviour ...

Co‐development of an integrated assessment framework to evaluate the effectiveness and impact of selected nature‐based water treatment technologies in Sri Lanka, The Philippines, and Vietnam

Environmental Quality Management, Volume 32, Issue 3, Page 335-365, Spring 2023., 2023
Abstract Water quality is a critical challenge in Asia in the context of growing industrialization, urbanization, and climate change. Nature‐based solutions (NbS) could play an important role in reducing urban water pollution, while generating multiple co‐benefits that could make cities more liveable and resilient. In this regard, a number of pilot and

Pest categorisation of Paracoccus marginatus

EFSA Journal, Volume 21, Issue 3, March 2023., 2023
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Paracoccus marginatus (Hemiptera: Sternorrhyncha: Pseudococcidae), the papaya scale, for the EU. It is native to Central America and since the 1990s, it has spread rapidly in mainly tropical areas of the Caribbean, islands in the Indian and Pacific Oceans, Africa and southern ...
