Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

Integrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Horseshoe Crabs

Horseshoe crabs (Limulus polyphemus) are fascinating animals known as “living fossils.” Older than dinosaurs, horseshoe crabs are arthropods, closely related to spiders and scorpions.

Freshwater crabs in Africa

, 2004
Freshwater crabs are a strangely neglected component of the world's inland aquatic ecosystems. Despite their wide distribution throughout the tropical and warm temperate zones of the world, and their great diversity, their role in the ecology of ...

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

Acta Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Computing Skinning Weights via Convex Duality

Computer Graphics Forum, EarlyView.
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.
