The avifauna of a naturally regenerating secondary forest, Pangani, North-Eastern Tanzania

Autor: Chacha Werema

Publikováno v: Journal of East African Natural History; Vol. 110 No. 2 (2021); 77–85

As humans modify native ecosystems with increasing frequency, natural habitats including forests are lost. Under such circumstances, secondary forests can increasingly be important to conservation of biodiversity at landscape scales. However, in East

Seasonal abundance and distribution of Red-capped Robin Chat Cossypha natalensis in the Eastern Arc Mountains, Tanzania

Autor: Chacha Werema

Publikováno v: Ostrich. 91:129-133

In Africa, the migratory status of the Red-capped Robin Chat Cossypha natalensis is still not well understood. In some areas, this species has been regarded as either a full or a partial migrant, w...

Learned traits are thought to be subject to different evolutionary dynamics than other phenotypes, but their evolutionary tempo and mode has received little attention. Learned bird song has been thought to be subject to rapid and constant evolution.

Inferring punctuated evolution in the learned songs of African sunbirds

Signals used in animal communication, especially those that are learned, are thought to be prone to rapid and/or regular evolution. It has been hypothesized that the evolution of song learning in birds has resulted in elevated diversification rates,

Seasonal use of remnant forest fragments by understorey forest birds in the Uluguru Mountains, Tanzania: a conservation priority

Autor: Henry J. Ndangalasi, Kim M. Howell, Chacha Werema

Publikováno v: Ostrich: Journal of African Ornithology; Vol 87, No 3 (2016); 255-262

Forest fragmentation can lead to extinctions of some species at local levels and is eroding bird diversity at an increasing rate. While there is information on the distribution of forest bird species in most of the Eastern Arc Mountain forests, some

Social selection parapatry in Afrotropical sunbirds

Autor: Elia A. Mulungu, Joshua V. Peñalba, Jon Fjeldså, Rauri C. K. Bowie, Maneno Mbilinyi, Louis A. Hansen, Jay P. McEntee, Chacha Werema, David C Moyer

Publikováno v: Evolution. 70:1307-1321

The extent of range overlap of incipient and recent species depends on the type and magnitude of phenotypic divergence that separates them, and the consequences of phenotypic divergence on their interactions. Signal divergence by social selection lik

Seasonal elevational movements of Eastern Olive Sunbird Cyanomitra olivacea in the Uluguru Mountains, Tanzania

Autor: Chacha Werema

Publikováno v: Ostrich. 87:189-192

Little is known about the seasonal elevational movements for most tropical avifauna species. Seasonal elevational movements of the Eastern Olive Sunbird Cyanomitra olivacea were studied along an elevational gradient from 600 to 1 500 m above sea leve
