Size-assortative pairing and discrimination of potential mates by humpback whales in the Hawaiian breeding grounds

Journal Article
Pack, A. A., Herman, L. M., Spitz, S. S., Craig, A. S., Hakala, S., Deakos, M. H., …Lowe, C. (2012)
Size-assortative pairing and discrimination of potential mates by humpback whales in the Hawaiian breeding grounds. Animal Behaviour, 84(4), 983-993. https://doi.org/10.1016/j.anbehav.2012.07.024
Assortative pairing, and its relation to mate choice, has rarely been documented in mammals. Using data collected from 1998-2007, we investigated size-assortative pairing as i...

Habitat preferences by individual humpback whale mothers in the Hawaiian breeding grounds vary with the age and size of their calves

Journal Article
Pack, A. A., Herman, L. M., Craig, A. S., Spitz, S. S., Waterman, J. O., Herman, E. Y., …Lowe, C. (2017)
Habitat preferences by individual humpback whale mothers in the Hawaiian breeding grounds vary with the age and size of their calves. Animal Behaviour, 133, 131-144. https://doi.org/10.1016/j.anbehav.2017.09.012
We investigated whether calf age and calf size influence habitat choice by humpback whale motherecalf pairs in their breeding grounds. During 1997e2008, we conducted focal fol...

The influence of crab burrows on sediment salinity in a Rhizophora-dominated mangrove forest in North Brazil during the dry season

Journal Article
Pestana, D. F., Pülmanns, N., Nordhaus, I., Diele, K., & Zimmer, M. (2017)
The influence of crab burrows on sediment salinity in a Rhizophora-dominated mangrove forest in North Brazil during the dry season. Hydrobiologia, 803(1), 295-305. https://doi.org/10.1007/s10750-017-3282-4
Many ecological processes are influenced by salinity. Burrowing crabs, abundant fauna of mangrove forests around the world, can facilitate sediment water fluxes, which may dec...

Journal Article
Findlay, M., Briers, R., Diamond, N., & White, P. (2017)
Developing an empirical approach to optimal camera-trap deployment at mammal resting sites: evidence from a longitudinal study of an otter Lutra lutra holt. European journal of wildlife research, 63(6),
