Vascular epiphytes in the cloud forests of the Serra da Mantiqueira, Southeastern Region of Brazil [PDF]

Rodriguésia, 2022
Vascular epiphytes represent a remarkable characteristic of the tropical cloud forests. The Serra da Mantiqueira (SM) represents one of the main highland areas of Brazil harboring vegetation remnants, and highlighting the cloud forests.

Adaptive movement strategy in rock-paper-scissors models [PDF]

Chaos, Solitons & Fractals 162, 112430 (2022), 2022
Organisms may respond to local stimuli that benefit or threaten their fitness. The adaptive movement behaviour may allow individuals to adjust their speed to maximise the chances of being in comfort zones, where death risk is minimal. We investigate spatial cyclic models where the rock-paper-scissors game rules describe the nonhierarchical dominance ...

Distribution and habitat attributes associated with the Himalayan red panda in the westernmost distribution range

Ecology and Evolution, 2021
The Himalayan red panda (Ailurus fulgens), a recently confirmed distinct species in the red panda genus, is distributed in Nepal, India, Bhutan, and south Tibet. Nepal represents the westernmost distribution of the Himalayan red panda. This study aims to

Spatial diversity and habitat characteristics of seagrass meadows with management recommendations in the Andaman and Nicobar Islands, India

Frontiers in Marine Science, 2023
The Andaman and Nicobar Islands, India, a geographically remote region, harbor a diverse island ecosystem. Limited exploration has hindered our understanding of marine floral biodiversity in this area.

Unlocking ensemble ecosystem modelling for large and complex networks [PDF]

PLoS Comput Biol 20(3): e1011976, 2023
The potential effects of conservation actions on threatened species can be predicted using ensemble ecosystem models by forecasting populations with and without intervention. These model ensembles commonly assume stable coexistence of species in the absence of available data.

Green Plants in the Red: A Baseline Global Assessment for the IUCN Sampled Red List Index for Plants [PDF]

, 2015
Plants provide fundamental support systems for life on Earth and are the basis for all terrestrial ecosystems; a decline in plant diversity will be detrimental to all other groups of organisms including humans. Decline in plant diversity has been hard to

Can anthropogenic variables be used as threat proxies for South African plant richness?

Bothalia: African Biodiversity & Conservation, 2007
Human demographic and socio-economic measures (anthropogenic variables) reflect the detrimental impact of humans on plant diversity globally. The Pretoria (PRE) Computerised Information System (PRECIS) of the South African National Biodiversity Institute

Far eastern curlew and whimbrel prefer flying low - wind support and good visibility appear only secondary factors in determining migratory flight altitude

Movement Ecology, 2021
Background In-flight conditions are hypothesized to influence the timing and success of long-distance migration. Wind assistance and thermal uplift are thought to reduce the energetic costs of flight, humidity, air pressure and temperature may affect the

Status, distribution and use of threatened tree species in the walnut-fruit forests of Kyrgyzstan [PDF]

, 2014
Information is lacking on the status of threatened tree species in Central Asia. This paper aims to provide preliminary information for 10 fruit and nut tree species of Kyrgyzstan. A field survey was conducted throughout the range of walnut-fruit forests

A threatened species index for Australian birds [PDF]

Conservation Science and Practice, 2020
AbstractQuantifying species population trends is crucial for monitoring progress towards global conservation targets, justifying investments, planning targeted responses and raising awareness about threatened species. Many global indicators are slow in response and report on common species, not on those at greatest risk of extinction. Here we develop a
