Ranging behavior of the Asian elephant in Sri Lanka
TLDR
The ranging patterns of Asian elephants suggest that conservation of the species requires their management both in and outside protected areas, and translocating and restricting elephants to protected areas will be detrimental to their survival, as it limits resource access.
Testing the roles of species in mixed-species bird flocks of a Sri Lankan rain forest
TLDR
The results show that birds with high propensity to flock, such as insectivores, use the vocalizations of nuclear species to locate flocks and that a sentinel species may be as attractive as a highly gregarious species.
The composition and spatial organisation of mixed- species flocks in a Sri Lankan rainforest
TLDR
The composition of flocks was generally stable over time, changing little over the annual cycle or between the 1980s and the 1990s, although the abundance of some species appears to have changed following regeneration after logging in the 1970s.
Multi-functional pollution mitigation in a rehabilitated mangrove conservation area
Abstract Many mangroves were forced to act as informal pollution mitigation zones and double up as conservation areas. Long-term data are presented for a high-profile mangrove reserve acting as such
ALARM CALLING IN SRI LANKAN MIXED-SPECIES BIRD FLOCKS
TLDR
It is suggested that birds in mixed-species flocks may be particularly aware of aerial predators for two reasons: a “numbers effect” whereby nongregarious species are more aware of predators when surrounded by large numbers of other species; and an “information effect,’ whereby species differ in the information available in their alarm calls, leading to an accumulation of information in a mixed- species flock.
Context-dependent vocal mimicry in a passerine bird
How do birds select the sounds they mimic, and in what contexts do they use vocal mimicry? Some birds show a preference for mimicking other species' alarm notes, especially in situations when they
The benefits of joining mixed-species flocks for Greater Racket-tailed Drongos Dicrurus paradiseus
TLDR
It is concluded that drongos are better classified as commensalists than as parasites, as they exact only a small cost on other species in flocks; they may even be mutualists, because they make sensitive and reliable alarm calls to which other species react.
Amphibian and butterfly diversity across a tropical land-use gradient in Sri Lanka; implications for conservation decision making
Asian rainforests suffer from massive deforestation but remain less studied pantropically. Although Sri Lanka is a severely threatened biodiversity hot spot with high endemicity and unique
Positive Relationships between Association Strength and Phenotypic Similarity Characterize the Assembly of Mixed-Species Bird Flocks Worldwide
TLDR
The association strengths of species in flocks are found to be strongly related to similarity in body size and foraging behavior and higher for congeneric compared with noncongeneric species pairs, highlighting the need to consider positive interactions along with competition when seeking to explain community assembly.
Response to conspecific and heterospecific alarm calls in mixed-species bird flocks of a Sri Lankan rainforest
TLDR
The response of birds to conspecific and heterospecific calls in a mixed-species flock system of a Sri Lankan rainforest is investigated, concluding that birds are listening to heterOSpecifics and suggesting that their response is influenced by several factors, including their foraging technique.
